    Get no argument from me that mining is about as tuff as it gets but not highly inspected. But i am a pretty fair muffler scabber most of the time.

    Muffler repair is as good as any of it. All work but its fast and saves a lot. Exhaust is so good anymore that failures are often local. No parts, little wire, 1/2 or an hour even and most outlast the car.
    I bought a car a while back had been somewhere for a repair and they fixed the exhaust.
    They did a really good job, simple and not his first go round with the feeder.

    There is more codes and specifications than written about. I books on subject and data from welding wire/rod manufacturers I had to use.

    I work in metal builds.
    But if you working in pressure tanks and pipes they live by different set codes.
    Each type of work has there own codes , rules and specifications to follow.

I used the NR 232 in a few shipyards as well. The NR 233 is a bit less moneywise a pound and I guess thats why Joe gets the stuff for me to use. Im the only guy there that uses it, and probly the only guy in Schuylkill County that uses it, the folks he gets it from tell me that Joe is the only guy they deliver it to. I know its got that seismic rating or classification or whatever and believe me these operators do just as much to these buckets as what an earthquake in San Francisco will do to a building or a bridge. Old Owen used to say this stuff is the ultimate welding test and I believe him

    I had a sprout moved on from me to a tile/underground outfit and he said they had to change their flavor of mig hard wire due to shock and awe.

    Steel such as T-1 is a different category than filler metal altogether. T-11 steel is to. According to Smithdoor's logic any T-1 wires would be suitable for welding T-1 steel. Nope, you need an equivalent to 11018. A higher tensile T-5 wire is the most common for T-1 steel. I actually like E71-T11 flux-core but also respect it's limitations. I used a bunch of it building the box for an end dump trailer. Great for welding the floor plates and frame for the box. The square tubing made for a nice penetration gap. Would never have used it for the main frame though. Lincoln even lowered the max. thickness it should be used on. Like I said previously, the original NR211 required about 28 passes on 3/4" plate to meet specs. 3/4" is now considered too thick. NR232 requires way less passes because it is superior in mechanical properties but still not the right wire for T-1 steel.

    I have to repair mufflers for the equipment from time to time, I think the steel is a wee but thicker for a shovel or dozer muffler than for a road vehicle, I never did it for a car or truck. We have a MIG but me and MIG aint really too good with each other, so I use 3/32 6010s for it and it works out ok for me.

    As far as inspection goes...I am my own QC guy...If I there is any doubt in my mind about it stayin together, I fix it...Its my name and my reputation on the line

    Probably the best muffler guy I ever met (worked in a Minute Muffler and hand fabbed me a partial header for a Ford 300 straight 6) used steel rods and O/A.

    I like using O/A brazing rod for exhaust and mufflers.
    When work large exhaust pipe over 4" I used E71T-1.

    There it's all about that extra 10000PSI tensile makes it work so good. 6010 would NEVER hold.


    Just kiddin'.
    An optimist is usually wrong, and when the unexpected happens is unprepared. A pessimist is usually right, when wrong, is delighted, and well prepared.

    Re: E7018 the right way and why

    The core rod in 6010 is the same as 7018, 7014 and even 6013. The flux makes the difference. A true craftsman does do their own QC even if there is no official inspector or requirement. Sometimes successfully repairing a large or difficult piece brings a great satisfaction to the repairer. It also helps restore your confidence that you know what you're doing. I felt this way after repairing my backhoe swing post that ripped the top swing bushing right off. Was so relieved it fit back together. The bottom bushing is on a 1 1/2" plate and I had to straighten that too. I ended up cutting a big V groove in it so only about 1/4" material had to actually straighten. Had to pre-bend it down to allow for contraction from welding and only used a bar tacked in place to keep it flat after it cooled a bit. Then I turned it over and ground a smaller V groove into the weld from the backside to make sure I had 100% fusion the full thickness. On final assembly a friend came with his welding truck and a large rosebud to get the final alignment for the upper and lower pins. So far it has held fine and I can drag the machine around. There was no sense doing anything less than a proper fix because you can't always baby the machine if you run into harder digging. I figure I saved 3-$4000 doing the repair myself and it justified buying the SA200 (which I got a great deal on). I am a qualified weldor and having the machine has been invaluable. I should point out that I would never have attempted the repair if I didn't have enough welding experience. It wasn't a DIY repair for a beginner weldor and had to be done right.

    Re: E7018 the right way and why

    That is kind of why some of us do this. When I left HS or before really as matter of fact took college welding and auto classes. Its kind of interesting but I aint that facinated and even though I got the book I havnt studied enough and onlu know if its thick heat it, if its harder use lo hy and keep it dry.
    The amount I really need to know about any of the rest of this minor and far few between. 50 or 75 thousand welds when I was working for others and 100 thousand more in my own shop and the times any of this including aluminum alloy I can count on fingers alone.

    Majority of failed welding has been from mfg under supervision. We ran in to a machine had some repair work doner, very ratty welding, not unstrong but a mess and the helper commented and I said,,, well the guy fixed something the book learned engineer designed 40 yrs ago and its still works.

    Re: E7018 the right way and why

    I will agree with POP that anyone done a bit or a lot of stressful fitup can compare tack strength, 7018 is better. All the half clamp and line up stuff.
    I have seen some testing, been tested a couple 3 times and done some tested work and compared a little during some rework. Some I thought would/should be a bit more critical but I guess as long as it was full and could be ground smooth it was pretty good. Good operators could really improve the clarity and even between pass clean was somewhat a factor.

    Re: E7018 the right way and why

    Its a trade and I need it. A welder can simply do work a non welder cant. Its a solution to so many problems. Bad news is it broke, the good is a couple hrs and 10$ materials and ita working again with a compentent repair. If it aint sposed to leak it doesnt. This is often different than the part time welder or should I say less than well trained types. I do some repairs save a lot of money and some seemingly simple pieces where the skill is the simplicity and the speed.

    Re: E7018 the right way and why

    Some of the stringint testing weeds out who is hired and who isnt. I entered my career a couple times not due to real know how but simply pass a critical test, some easy ones too. I dont watch a lot of Jody but he is really good and been there, I can feel what he talks about. He is way more studied and disciplined but had a hot berry in the shorts a time or 2 and for giggles I watch a 6013 demo he did and his experience is almost identical to my own, I know exactly what he means. Also had an instructor put me 2 days in the booth on a buzzer and 13.

    So if you doing work that is inspect and or x-ray ( testing) you would do the welding different ?

    The next question if work is being tested and or inspected how would you do the work
