ive got some local TOOLBOX who wants me reair a snow plow, i havent seen it yet but he says its a SMALL REPAIR now i have a AC225 BUZZ BOX and my hoFART 135 WITH FLUXCORE i feel more comfortable with the mig but im leary that the machince wont have enough NUT for this repair
and helpful hints as far as preheat or beveling or peening or what ever, thanks brian ?
hes three towns over, i was thinking $25 just to check it out and then $25 hour ?????????????????

You most likely will not have enough power in the 135 unit. I would not hesitate to go with the stick. $ 25.00 per Hr. sounds pretty low, but if it works for you both go for it.

thanks for the quick reply, but i feel more capable with the mig, and its easier to transport , ive got fluxcore .35 wire and need to know if multi pass beads are a option, thanks again brian

A tig class huh!
You posted this over on the dark side.
(quote from arcdawg)
i consider myself a pretty good tig welder. the problem that i face is all of the buttons and switches, polarity really gives me headache. i know about ac is aluminum dc negitive is for steels but on certian machines its worded funny, like dc straight and dc reverse. why is that, i believe that dc reverse is for smaw but its just to g.d. confusing, what ever happend to those olde lindes........ now im using a syncrowave and i feel like you need to be a rocket scientest to run the welder............... helps or hints would help me out so much thanks brian
I would be hesitant to pay money for a class, where the instructor didn't understand a simple thing like polarity!:dizzy:
arcdawg
01-31-2004, 09:40 PM
your right jim, its stupid to ask for helpful hints.
i thought that these boards are here to help each other?
if you dont want to help i would ask you not to reply to my threads.
and if you READ my polarity question it states the i do know about the settings, i was just asking for easy way of rembering them.
i would like to see you have 10 guys asking you 10 diffrent questions at the same time and be able to HAVE ALL OF THE AWNSERS

I was a certified instructor in the Navy. I taught a six week maintenance course. I've taught Florida DEP approved regional short schools on maintenance. And I've taught the Florida concealed weapons permit course.
The key to being a successful teacher is to be intimately familiar with your subject matter. By reading your posts it's obvious that your not.
For the odd question that I couldn't answer, I'd tell the student that I would research and get back to them.

Probly wears a neck tie and a lab coat too.
Seems like if he was hooked to the proper equipment he could power a small subdivision.

I don't think that anyone should be put down or insulted for asking a legitimate question. No one is so smart that he/ she can't learn something new. Egos and self back-patting should be left at the door. There are always helpful hints that can help someone retain information.

sorry guys the only time i wear a tie is to a wedding or a funeral,and just to let you know i work as a welder full time and the n i teach a class one night a week and if i have to sub i will. if i was such a BAD teacher i doubt that i would get the chance to keep coming back. last semester i had around a dozen guys in the class and after the saftey lecture i had all of them welding the first night. these guys pay to WELD. they are given a book that we read thoughout the class, but my main focus is for them to WELD,you dont learn hoe to drive a car by reading the book do ya ?

Wihtout more details on what exactly needs to be repaired, its pretty hard to offer advice on process selection or any good hints. Unless he wants you to fix the sheet metal housing of the hydraulics, you probably are going to have to use the stick. Get some pics, or details of the repair, for better advice.
What fluxcore wire are you running? If its E71T-GS you cannot multipass with it.
arcdawg
02-01-2004, 02:30 PM
i just wanted to say thanks for taking the time to reply, i really have no idea what this repair is going to consist of. i was talking to this guys employee on fri night and he said oh my boss has a small repair, i always look for side work..... in my mig right now im runnig FABSHEILD21B IS THIS OK, i was thinking multi pass if its a frame or somthing over3/16 and should i preheat? is the metal that the frame made up of heattreated or work hardened ? thanks again brian

Here is a link to that wire's specs: http://www.hobartbrothers.com/product_details.asp?prodID=18
As you can see, its rated for multipass.
Without seeing the part, its impossible to even guess if its hardened or not. Preheating can cheat your way into having a little better fusion and penetration, but if its just normal steel, its not required beyond bringing it into the 200F range to drive out moisture (or at least room temperature). If its the frame or bracket that bears signifigant wieght, and its over 1/8th, you would be doing a great injustice to your customer by not using the stick. In the long run, its better to tell a customer 'i don't have the equipment to do this thick of a repair', than to do a repair that will fail due to poor fusion or poor technique. You might not make the money from this job, but if you repair it, and the weld tears out, you've lost the customer for life, and probably some badmouth to his friends.

I have and use snow plows and they really take a beating. I would heavily suggest you give your back a work out and use that stick welder. I have repaired and modified (3rd trip spring) my plow several times and once had it repaired by a plow service shop (i happend to be plowing at the time of breakdown, what luck!). My A frame broke at pivot and head mechanic beveled it and reweled it with stick welder. Only hardened part of plow I know of is cutting edge and you replace not repaire that.

Arcdawg;
Take this for what it's worth. But from your posts, you don't have the skills, or knowledge to do this Job. Do the plow guy a favor and decline it. It would be safer for both you and him. The plow guy won't have his equipment fail`, and possibly cause damage or injury. And you won't have that on your conscience, or face litigation.
I mean this in good will. You seem like you have a lot of pride. Causing a serious injury would probably devistate you.

hey buddy, i am more than able to do this job... the line of work that i do my welds get inspected by the fire marshall of the town im working in, i have currently installed over thirty hoods and have run a few lenghts of duct in my day AND EVERYTIME I PASS THE INSPECTION,
the reason why i posted this tread was to get some feedback on the plowframes them selves and to see if my mig would be powerful enough,
i have built trailers, rebuilt and hardfaced buckets, put floor pans in cars,built kitchen hoods and whatever comes my way s oa little repair doesnt scare me
however you make a valid point about people being SUE happy, i will give you that much....
i would say that i have more skill and knowledge then you THINK.i dont think that its a good idea to discourage someone from a good work experience.....ill bust out my stick machine and lay some sweet beads that will be there longer than the truck itself....
I do not reply much here but I would not use a 135 machine for plow frames, moldboards and such. I have fixed, rebuilt, fabricated and welded many plow frames and the like. I have fixed other "welders" work who have welded with 135 machines and it had minimal penetration and always broke again. Why do you have to go to the plow. As for the plow, you did not give details on the repair. Is it the frame or plow or uprights. Have the customer come to you if you have a shop. If you do not have a larger machine then I would also pass on it. Cause he will be M/Fing you at 3 am when it breaks again and he is trying to plow and make money.

If I were you I would think about using someones machine to complete this type repair. I too have made many repairs to snow plows with my Ranger, you see the problem is these guys get in the truck and tear things apart with them. And when something you repaired fails due to them trying to be a hero plowing into something like a stone wall at 40 mph thet tend to get mad.
I have always added more materail to the repair so something else will fail before the repair does.
Go heavy on the welds, I hust think a 135 will look good but will not take what they will do too it

well i went out around 6 this morning with stick welder in car. drove out to the guys garage set up my grinder, welder and started grinding(that took the most time)
so i cleaned up the whole area around the repair. disconnected the battery in the truck too.
i beveled the area out (old reapair) it as clean as possible and went to town, it was a flat postion repair nice and easy. i used 1/8 7018 running around 120amps did a root pass then a really nice cover pass
this was much easier than i had thought. when i was done i hooked up the guys battery and loaded up my car. sprayed some rustoleum paint on the repair and collected my $50.00
thanks to the guys that steered me in the right way the stick was the way to go....

PJ you don't scrap cutter edges, you wear them in to get the proper corner releif, and then run a pass of Stoody or other abrasoweld across the bottom to triple the life. When the abrasoweld wears off, you just run another pass across the edge.
The same rod will dramaticly extend the life of shoes as well.
Jim, about that Florida CCW course, just how many seconds after shooting the hole in the paper ballot to eliminate the chad problem, and realizing you calculated windage wrong and accidently removed the head of the idiot holding the punch card in front of the TV camera are you required to say OOPSIE within for it to be a legal shooting?
1/8 7018 on a snow plow, am I the only one thinking hydrogen embrittlement?
Franz,
I have some of that Stoody hard surfacing rod, but I can't make as nice a weld with it as I want. I can make a lot of different rods lay down a good bead, but the 5/32 Stoody rod seems to elude me. I am wanting to hardface the 8' cutting edge on our Cat loader, as it costs $400 bucks to replace. Any suggestions on how to run that rod? It is real hard for me to keep a good arc going with it. Thanks.
Franz
02-05-2004, 02:21 AM
HS rod likes to run HOT, and it don't really lay down pretty unless you use TIG to place it. It also works best in flat position, so you want to plan the job and have appropriate lifting equipment to orient the work.
It also doesn't want to build up worth squat, so you pretty much want to lay it on in a single pass and do the buildup with something like 7018 or even 6013.
If you have to work to a shaped edge, run up to a carbon block.
I've never had much luck restarting HS rods either, so you just figure on tossing some long stubs.

I admit I find your skills suspect, do to lack of information of your posts. I've been in this field off and on for over forty years. Your posts seem to be lacking is substance.
Is this craft center an accredited facility? Do the students get credit for the course, Either CEU's, or college credit? Is this a private, or state sponsered school?
arcdawg
02-09-2004, 11:37 AM
its a private school, for people that want to pick up another hobby , or better their skills, i run a class one night a week and i have been for 3 semesters now.
so i really dont care WHAT YOU THINK,
you ahave singled me out eversince i have been on this board, and thats fine,
i just dont understand why you keep harassing me ?
this is suposed to be a way to learn from others, i try to help out when i feel that i can,
do you get off on putting other people down?
some one with your SKILL LEVEL ? should support the young welders and not critize them
According to my calculations, using the information you have supplied, it will take 2.77 years to complete one cycle of the classes you teach, this assumes an 8 hour class day.
do I have that right?

Arcdawg;
I got on your case because of your condescending attitude, an example is the above post "Some local toolbox". and the post over on the darkside about "HH135 sucks" I hope that in the future you will be more mature on your posts. Hobart went out of their way to make your used machine right, in spite of your rude post, even though they didn't have to.
Also you comments about Foreign workers seem kind of racist. You make statements without real facts to back them up.
I hope you mature a bit and do a little research before you post. I utilize references while I'm making a reply. and sometimes quote my sources.
Also slow down, watch your spelling, and grammer and you will be a more effectual poster.
I mean these criticism's in good spirit.
And look forward to hearing from you

Jim, read this description of the "repair" Arcdawg made.
"i beveled the area out (old reapair) it as clean as possible and went to town, it was a flat postion repair nice and easy. i used 1/8 7018 running around 120amps did a root pass then a really nice cover pass"
I don't see any mention of preheating, but I do see indicia of hydrogen embrittlement in the weld, witch is probably why the first "repair" failed.
Pound for pound, snowplows take a worse beating than the pusharms on a D-8 or dipper stick with bad bushings, and yet the operators seem to think a halfassed repair weld will hold up. The primary criteria for selecting the weldor to make the repair is how cheap the guy will hang birdcrap on the steel.

Here's my little input about some of the things discussed in this thread. I have tools, have had very little formal schooling in welding (3 levels of credit night school classes) to advance my welding skills for my personal hobby (cars) and job (various fab needs). Probably the best thing I learned is know what you can't/shouldn't do. While I have the tools to build or repair something that could severly injure someone, I won't. If a quarter panel falls off a car probably no one will die. If one of my little fab jobs at work fails, no one will get hurt. If the possiblity of my "poor" craftsmanship can hurt someone I say no in a hurry and call in the certified welder I use at work for such a job.
A smart man knows what he doesn't know.
An arts and crafts welder should not be building bridges. Odd example but you know what I mean.

Arcdawg: I'm not going to jump on any bandwagon, but you kinda asked for it when you touted your "teaching" and then all your early posts were full of horrible grammar and spelling, admissions of not knowing basic welding controls and terms, and a prideful attitude. If I may make a suggestion, I recommend asking legitimate questions, and discussing the answers, as you tried on this thread. DON'T answer questions to which you don't know the answer. Don't bring up your teaching as some kind of certificate. Use your helpful advice on the subjects for which you are knowledgable to speak for you. In time, the others will forget about your hasty indoctrination and you will be welcome to ask more questions and post about what you do know. Apparantly, you do have some experience. Don't tell us about it. Let us see it come through in the quality of your postings.
Everyone else: Let's give him another chance and see how it goes. He can either be a welcome addition, or I'll not stand in front of him again.

some people on this board really enjoy pointing their fingers and think that they are the only people in the world that have any idea about everything.
as far as my spelling goes.... is it really a big deal
my views on illegals is just that, my view
how quickly some people are to defend undocumented workers, maybe cause they employ them....
when i asked this question it was for help, i dont do much repair work and wanted some advise, not my stones broke...
as far as my teaching goes, i fell into this and i love doing it, i might not have all of the awnsers but i TRY THE BEST THAT I CAN,
to get everyone welding and show them the safe way of doing things
i might have come across as a know it all when i first signed up but i think that if you looked at my more recent post you would see that i do have something to offer this board.
and if you dont like my post or my replies you dont have to respond, really its that easy
thanks to the people that gave me advise

02-11-2004, 08:04 PM
Brian, I'm gonna try this one more time, clearly and succinctly, in the hope you get it.
You come across like a 15 year old kid, who might own a welder and has read some pamphlets, and if that's what you are, fine, but you ain't a weldor. You ain't a fab weldor, and you sure as all hell ain't a repair weldor, and I assure you there are guys here who are both.
You came up bragging on how you "repaired" a snow plow, and frankly, the job you did was NOT a repair. The best part of your work was squirting Rustoleum on top of an improper weld.
The sad thing is you didn't even realize you were making an improper weld. Your rod selection, 7018, was a LH rod, and you used it on a cold piece of steel, so you certainly created hydrogen embrittlement in the weld zone.
You went on to state you ground out a previous repair. That should have told you that you were in over your head, but you lack the skill to recognize that. The degree of difficulty goes up tremendously when you're trying to remediate somebody's prior screwup, and you damn well better know what you're doing.
Now, that might not seem like an issue to you, cause you got paid, and you can get paid again to redo the halfassed job when it fails, but to me, you created a ticking time bomb, completely unnecessarily, and you have placed in danger the lives of people you may never meet, unless it's in a courtroom in the future.
I sure hope your weld wasn't in a criticale area, like the A frame or the Quadrant, because when welds fail inthose areas plows come off. Even that might not be a problem if the plow is pushing snow in a parking lot, but if a plow breaks loose at 50mph, it is a disaster.
I've seen too damn many close calls, from trailer hitches coming apart to stairway collapses, cause somebody thought they knew how to weld. This craft ain't rocket science, but it does take some time to learn, and a lot more to master, and those of us who have been at it a while know we will never master the entire spectrum of welding. It's not just a matter of piling crap on layer upon layer, it's about knowing what the he!! you are doing before you hook up the ground, or walking away from the job.
On things like plow frames, you generally not only have to replace the original weld, you have to reenforce the frame to compensate for the structural defect developed by the original failure. You didn't do that, you didn't even know you had to do that, and you shouldn't have done the job.
This craft isn't about putting the money in your pocket and driving away, it's about seeing your work 10 years later, and being proud you did it right, and it's still performing.
Those of us here who see it that way are more than willing to help younguns who are trying to learn, and we'll bust *** to help, but don't expect a pat on the back when you screw up, this craft simply doesn't award points for trying.
Franz, I've been reading your posts here, and for a longer while back at the dark side. I don't always agree with what you say or how you say it, but I have to admit you're always fair. More than that, it's clear you been "ridin this rock" for a while and know when to speak up, and perhaps more importantly when not to. I thank you for your contributions and insights, even when it's not what I want to hear or read.
You nailed it with your last post, and I hope that the intended recipient takes it to heart and doesn't get all beside himself again trying to justify or defend.
I think you (and others in this thread) have offered him some good advice.
It's important that you and the other experienced folk are here; and it's good of you to treat some of the more ignorant folks on these boards as well as you do.

Franz, your last reply was well stated and your your patience is admireable:angel:
can anyone relate to this?
I just ran across this thread and I am wondering why, when someone was asking for knowledge to be shared, that so many were so stingy with advice. If you had an inclination that the person was not up to speed on stick welding (having to borrow a stick welder is a good hint), wouldn't it of been better to give him the knowledge to do the job correctly to prevent the possibility of injury to equipment or personnel (as many now claim to be so worried about after the fact)? I lucked out in this life and have been blessed with having an outstanding welder to be my teacher for three years in college, and to having equally outstanding welders in my town who will come to my aid if I have questions or need help. Too bad arcdawg doesn't have that in his town, or as it seem, on this board(not an indictment of all, just a few). As the trades seem to fall by the wayside in our schools, where do we think people who want to learn these skills are going to go? Since arcdawg has assumed the mantle of trying to teach others these skills, wouldn't it be more productive to make sure that he is given the knowledge to do this properly? Or is it just more fun to break his chops?

dog, thanks for replying to my post. i have decatated the past five years of my life working and learning in the welding feild.i dont really get many repair jobs and if i do its not stick welding.i think that what happened on this board is that i probably came on as a smart @## or a know it all, which is far from who i am.
and after this post blew up in my face no one will respond to my post:confused:
so i look for post where i feel that i can give some good advice and some helpful ideas, which is all i would expect in return.
thank god that there were some GOOD GUYS that dint have to bust my stones and gave me the advise that i needed, books and schools are great but real world advise works best for me.
thank you again for taking the time to respond and possibly see it the way i saw it,

Arcdawg,
No sweat. If you are new to welding, I would check to see if you have a Blacksmithing Guild in your state. You can hook up with them and learn a hell of allot from those old farts. Also check around the local airports and see if you can find out who does their welding on aircraft for them. Great welders seem to get their names mentioned alot . See if you can trade some sweat equity for some instruction or question answering. There is a good discussion on hydrogen embrittlement of the mig etc board. I prefer to lurk on these board, as knowledge can be gained wherever you go. Keep teaching, and more importantly, keep learning and practicing.

Brian,
Hey friend I read your post, and the subsequent follow ups. I was rather disappointed in my fellow welders. I am a professional welder. I don't know if you consider yourself that or not. It merely means I bring home the bacon on welding. If my welds don't cut it, people get hurt or die and considering how much work I do thats a lot of hurt people if I did not know what I was doing. I reckon what I have to say is that theres a lot of people out there eager to bust your butt and make a lot of threats, but seeing as much as I have seen and know what I know, Im sure its goin to be just fine. Another thing is, I noticed how eager ppl who claim to be veteran welders are to tell you dont do it dont do it. Well if your soo damn good than why not tell the man how to do it. Instead they wait till you did what you did and than ridicule it. Ive seen it and a lot worse. Ive heard it a lot. I run outta my own truck most of the time now. For one cause I can, my own machine, my own tools, and lots of experience. And for two I got tired of sorry welders who use insults on others to build themselves and make them feel good. As for your description of your repair. Well provided the weather wasnt as below freezing you prolly didnt warrant preheating on most components of the plow. Wouldnt have hurt, but wouldnt be a requirement. Other tips, I prefer to run a 6010 on my root and fill and cap with 7018. Provided your 7018's are nice and dry they will keep the hydrogen content to a minimum and hopefully eliminate any problems due to hydrogen. I think this hydrogen embrittlement they are talking about is hype. Yes it does exist. Its very bad. Basically cracking that occurs hours or even days later due to EXCESSIVE HYDROGEN. If its due to excessive hydrogen, then I have to ask why is there a problem using a LOW Hydrogen rod IE E-7018. I have found nothing in any of my text, notes, nor from my friends and colleagues regarding why preheating would make a significant difference. Biggest thing I hear is to make sure them 7018's are dry. Buy them in the smallest box sizes possible. Its more expensive that way, but better. They are very susceptible to moisture. I have seen accidents where a welder welding mild steel conveyor pieces put in weld on a approx 1/3 the circumference of the stacker. Than 8 or so feet into the air it broke. THe culprit was truely unknown. However, it had not been thoroughly cleaned and the rods were not fresh. I ramble, I apologize for that. Its the engineer in me I suppose. What I would like to leave with you though my friend is that I wish there were more ppl like you out there. People willing to take a chance and learn something. Good or bad, and then take what youve learned and pass it on to others. Welding is a lot of different things. ALthough some of these clowns think welding and painting are not in common, I think not. The ironworkers of the 20's and 30's were like ballerinas dancing around on 4 inch beams. Even welders together, its an art it really is. Someone doing metal sculpture or a birdhouse is just as talented as the men doing the pipelines, just skilled in different ways. I hope my message can be better conveyed to your class. I think they have a good instructor, I think his biggest problem is the information field that attracts to him. Good luck to you, I hope the best in your career and I hope welding is a good to you as its been or me . CHRIS
