Stercorarius Posted May 29, 2016 Report Share Posted May 29, 2016 7018AC rod on a worn out loader bucket that I'm trying to get to limp along for a little bit longer. What are your thoughts ( I am particularly interested in what comp has to say as he is welding Yoda)? Be as critical as possible. I want to know everything I am doing wrong. Honestly don't care if I did anything right. My thoughts are that I ran it too cold and should have ground out a groove in the cracks first. Are the bubbles in the weld when I let it arc out too far? Transitions between strings is kinda shitty, no? Thought about preheating it but had just ran out of O2, would this have helped? I'll grab some pictures today of what it looks like after a couple weeks of heavy abuse. Is the black outline around the HAZ that you can't see on these pics but is pretty obvious now carbon that rose to the surface or microfractures? 2 Quote Link to comment Share on other sites More sharing options...
JimboS1ice Posted May 29, 2016 Report Share Posted May 29, 2016 Better than what I could do... No welding experience I've always wanted to learn Jimbo Sent from my iPad using Tapatalk Quote Link to comment Share on other sites More sharing options...
comp56 Posted May 29, 2016 Report Share Posted May 29, 2016 well here you go, bubbles can be caused by a few things, improper angle if your running gas ........flow is low so it contaminates. or even bad gas ......if you are running fluxcore might be moist. yes you are running cold and rushing. grind it out and run root pass and 2 caps slow your roll...... 3 Quote Link to comment Share on other sites More sharing options...

KnarlyCarl Posted May 29, 2016 Report Share Posted May 29, 2016 Interesting, that actually made sense. Also a working helmet can make a difference too lol.. If you grind it out this time, do you need to heat or does the grinding heat it enough that won't be necessary?

Stercorarius Posted May 29, 2016 Author Report Share Posted May 29, 2016 Had to run into work for a few hours. Grabbed a couple pics of the welds after a couple weeks. Some held some didn't. 1 Quote Link to comment Share on other sites More sharing options...
JimboS1ice Posted May 29, 2016 Report Share Posted May 29, 2016 Could you weld it from the other side too? Jimbo Sent from my iPhone using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...
Mondo1310 Posted May 29, 2016 Report Share Posted May 29, 2016 That 7018 is one versatile rod. Those buckets take some serious abuse. 2 Quote Link to comment Share on other sites More sharing options...

Jimbo Sent from my iPhone using Tapatalk Yeah, but if more of the welds start to crack or decide to pull apart I'll probably just take a grinder and grind it out and do passes like comp said to where it fuses all the way through. I'm going to leave it for now because they want to just replace the whole bucket with a bigger one soon and scrap this one. If that doesn't happen before it needs rewelded I'll have toTry again.

You said rods, so there shouldn't be any gas involved. If you aren't that practiced in welding, you will find welding on a flat level surface is the easiest way to do it. Grind it to a clean metal, groove it out where the cracks actually are. I am going to guess once you do those 2 steps you will find you didn't find the end of the crack, it was a little longer and hidden from you. 1 Quote Link to comment Share on other sites More sharing options...
