Default Good job gone bad

I am transmogrifying a WMC bucket for the JD544 as the one it's wearing is thin enough that the sun shines through in some spots.
The ears had to be air arced off and I cut new ears from 3/4" plate on the plasmacam.
I plotted out the bucket angles and moved the ears out 5 inches from the position of the present bucket so it will curl up more and carry the load without spillage. I made bushings from some DOM that I had for pin supports and to put a pin keeper bolt in. About this time I wished I had a turntable to weld these things as the weld, stop, turn, start, stop, doesn't make a pretty weld.

So far, so good, and the air arc job went better than I expected, except I dug too deep in spots, but I just run a bead to fill the groove. It's easy to get carried away with the gouger.
I ground the crap and rust off the surfaces and welded braces onto the ear to control warpage. I spaced the new ear out about 1/8-3/16" and opened up my last steel can of 5/32" 11018 and used 165 amps to burn in a root pass. I tried 175 and there was too much spatter, but still it went in deep.

So far everything is going well, and I took some pictures for the forum.

Nice fit up for an the irregular contour your dealing with It sure makes the job of welding it up go smoother.

Now my plan was to do 3 stringers with the Mig and .040 wire.

So now the shit starts.
I laid one down next to the root. It was a bit funny for spray, snapping and spitting occasionally. I turned up the voltage and started bead #2 and then it seemed good but when I stopped and looked at it, there was some spots where it had puffed up like a pregnant worm. So I ground that out and re-welded it.
Then I went to work on the other side, and there seemed to be the same problem. I thought maybe not enough gas, turned it up to 30 cfh.
I laid down the last stringer and it was terrible. So I looked at the gun and the Miller has an insulated nozzle, and a bit of it was hanging into the gas flow. I stopped and went into town and bought some new gas nozzles.

As this is an old feedlot bucket it has soaked in silage, piss, and shit, for a lifetime before I got it. I have come to the conclusion that it is deep into the steel. When I welded up the grooves I cut withe the gouge rod, they were perfect, so maybe I needed to grind deeper.

When I got home, the welds did not look any better, worse actually. So I air arced the worst sections out and welded it back in with stick, and then in some areas I had to go in and gouge the adjoining area to the stick weld and redo it. I am wondering if the impurities trapped in the first 2 stringers from the surface were concentrated and killed the third pass.

All in all, a mess that I am not proud of.
So there it is, a lumpy mess, and I am set up and rooted in for the last two ears.
Spray has great penetration and is so nice and smooth.
I ground out the area thoroughly, I am tempted to try once again with the wire.

But not tonight.

Been there, looks like a good spot to leave your coat in case you get company.

Oh Lordy that is the shits. Can you maybe hit it with a rosebud and try to cook the crap out before you try to lay a bead. The appearance of those sections reminds me of welding in new liners in Rearload hoppers. Everything is cruising along just fine then you weld over some chunk of crap and the gases from it burning/boiling off blows a bunch of holes in the weld pass

Some days you are the windshield, some days you are the bug. Glad to know I am not the only one that gets those days.

Tomorrow will be better, Gerry.

I can do it all with stick, I just wanted to have a nice job. It is harder than ever to work at chest height with by bad arms so I have to limit myself to 3 hours. I have to preheat first thing and maybe I'll try roasting some stuff out of it.
I was aware that after gouging due to carbon left behind you should grind out the gouged area. But this is 2.5" away from that zone.

Oh well, It's not over yet. Still another 120 inches of weld to do.

This was not pin holes, the nice flat bead all wetted in at the edges looked good from the helmet. Behind the puddle it inflated the bead up at least 1/8 or 3/16 high and when I broke into it there was the holes. Inside it looked like a cake mix.
I figured that it was useful to post anyway because someone may learn from this besides me, and there may be a solution to this problem, besides stick.
