    That is some pretty welding. Almost a shame to run it in the dirt.

    Thank you, yeah i know, sometimes we get lucky and there isnt a whole bunch of dirt to fight while weldin this stuff , but not very often. But like old Owen used to say pretty welds are nice but the dirt and rocks dont giva**** what it looks like, the customer just wants it to stay put. Some guys get all bent out of shape if a ripple in the weld is out of place, i used to be like that myself. Worrying about all that will just get you all twisted up in knots, and you can do all the stuff you want to combat the dirt and sulfur in the iron and all that and you wont get the thing done in a reasonable amount of time, but we try to make it pretty without wasting time over it

    Always great examples of 'Heavy Metal' ^ ^ ^

    Have you ever used E11018, and experienced tearing down
    the center of the bead? If so, what was your remedy?

    Looking good.

    Hear you on the pretty weld thing. One of my newer guys was grinding a really good weld at the end of a wear bar because he likes them all perfect. I told him to leave it be, it was going to wear off in 300-500 hrs anyway.

    When i was workin with Owen years ago we would use some 11018. Bernie the owner of the mine would go to these sales and buy up all the weld rods left over from the power plant jobs or whatever they came from. There was always an intresting mixture of rods. All new stuff and still in the boxes and cans so they were all good, but mainly what we used was 7018 and sometimes we would grab a can of 11018. We ran it and never had any problems with cracking anywhere, and those boys are still diggin with those buckets today.

    Joe (the fella I am contracted too ) sent his stepson out one day to repair a boom either on a Demag or Komatsu PC4000 I forget which. Now Demag and Komatsu both have a welding procedure written for welding their booms and such, and 7018 is specified and of course the kid, being the know it all he thinks he is decides he is going to weld this with 11018. Yup it cracked overnight, so he does this again and it cracked, where at exactly i dont know. Well, this went for about 3 or 4 days and he still dont have it fixed. So Joe himself goes out to see what the trouble is and when he sees what he is runnin he has a damn fit. Joe tels him cut that stuff out and do it the way it supposed to be done. Yup 7018 fixed it right up.

    About 12 years ago was takin weld tests with 11018 at a shipyard. For what reason i dont know, i never saw any 11018 out the yard

    11018 is generally used for T-1 and isn't necessarily a stronger alternative to 7018 as evidenced by the boom cracking repeatedly.

    My experience was similar . . . but first - regrets -

    I am known to rail on those that don't provide details, and back-
    ground of their quandary - to adequately answer their query . . .

    In post #14 - I was one of them - 'I'll do better boss . . .'

    After Welding School, and two years of experience in an Industrial
    Shop [of 318 - 65 were Journeyman Welders - all new metal fab.]
    I jumped to field equipment maintenance on a 1200 mile power
    line.

    I am Dorothy in Oz . . .

    My heartburn was replacing the mould board on a D-8 blade.

    The operator's had burned thru the cutting edges all the way to
    the plow-bolt holes . . .

    I am no longer in a shop with a Welding Engineer [metallurgist]
    but, now subject to an Equipment Master Mechanic . . .

    He said use this - it was E11018. Even with unlimited - preheat,
    post heat [with blankets] it cracked, and cracked, and cracked -

    The 'real reward' was Arc Gouging my own work - over & over &
    over . . .


    I gave up - I gouged one last time and filled it with E7018 - and
    never told the Equipment Master Mechanic . . .

    It held for the duration of my three years on the project . . .

    If anyone has deep knowledge of - when/where/why, E11018 was
    'the go to rod' - please post, and bring me up to speed . . .

    I'm aware: Dual-Shield has obsolesced stick on heavy equipment,
    but sometimes 'stick skills' are the only option . . .

    Ideas . . .

    Ive never really ran into anything that 11018 was required, me and Owen used em mostly by accident, we would each grab some rods in the early early morning when we couldnt see and head on up the mountain. There was never any proper storage for these rods, they were all just settin on a table waitin for us to grab what we needed. If it was 1118 or 7018 we used it as long as it was lo hydrogen. Most of what we welded with em was wear plates and bars and it worked fine. These days i use 11018 for building up stuff like tooth bases. It works good for that, run a layer on it and then get it just about red hot and then beat the crap out out of it with a hammer, the more you beat it the harder it gets

    I agree with you about stick welding, sometimes a wire feeder runnin whatever you choose as far as wire goes just wont work, get out some rods then and do it the old fashion way
