Not mine, but I might have done something similar before. <lift hood, sigh, reposition to start weld again....>

It has to hold 440' of 1½" steel pipe. Normally we install the well casing then the tremie pipe but this next job we will be installing the tremie pipe first the way we support the pipe while installing it will block too much of the hole and we won't be able to get the well casing in. This new clamp will let us support the tremie at ground level.
The plate has the same size hole in it as our bore hole so if something goes wrong the casing elevator can't fit down the well.
 
Rebar does not weld nice even with a super grind/clean. What is this material??

this material is junk. but serves its purpose in concrete not fab..... :lmao::lmao::lmao:

There are quite a few different kinds of rebar. Depending on the carbon content, etc, some is weld grade, while others aren't as it is made up of junk. The rail steel kind isn't fancy W grade as far as I know. A roof bolt / rebar plant I used to fix cranes at made both kinds, and made their own billets for the line of good stuff. Other than roof bolts, I'm not sure what the application was for the better rebar.
 
its is crazy how some will break right out side the weld when given a minor load and others can take it. i see the jersey barriers use rebar loops to tie them together, at least it looks like rebar. its all about the grade thats for sure.
 
Fuck me. Just couldn't get this part of my boat to wet in right. Giant ass heat sink. Fixing some pin hole leaks in the factory weld on the keel.

Attempt 1, low on gas. Lots of porosity.

Ground out and redone after new tank of argon. Super awkward position and just couldn't get a good angle. Gonna smooth it out with the sander tomorrow. :flipoff2:

propane torch for preheat can do wonders for aluminum when you don't got enough amperage
 
Probably would have helped. Think I need to turn my frequency down to get a fatter puddle.

It's dirty and heavily oxidized. Clean the oxide layer off better.

Acetone followed by stainless steel brush one direction. Hit it until you think it's clean then keep going then wipe with acetone again.

Mild preheat to like 200 helps a lot
 
I hate aluminum. I have no idea where to ever set balance freq and all them other fancy knobs. I always do a fusion pass afterwards to wet everything in and make sure that everything is solid.

leave frequency at 60hz
leave balance at 50%
works good enough for my old transformer machine

more cleaning on the ac balance reduces available heat in the work and increases wasted heat in the tungsten
more frequency makes your bead narrower because the arc has less time to wander before being restarted after the polarity switch

Nope. It's ground out, stainless brushed and acetoned. Even hit it with the AC cleaning action before puddling. (first pic was on a super low argon tank so think that was causing the dirty look)

Need to set your balance for more cleaning action

It's in the sweet spot on this welder (AHP). I've messed with it a bunch.

See I can TIG aluminum pretty good, just not out of position :lmao: This was the same night I was welding on the boat. Same settings just lower amperage.
