I pie cut the ducts on a Detroit Diesel air cooler to spread them apart an inch and a half. Used a Lincoln Tig 300 with watercooler and 4043 to welded it up. I think 5356 would have been a better choice but the boss wanted it done with what he had....so the unfortunate part I was stuck trying to use 4043 and a balled Thoriated Tungsten.....it didn't come out too pretty. I know thoriated isn't the right tungsten for the job and I can see why now. Dave

Why did you ball it?
I never ball my thoriated when I use it on aluminum, and it's practically the only tungsten I ever use (transformer machine, no less).Syncrowave 250DX

Airco MED20 feeder

As c wagner says "don't be too hard on yourself".
Seeing as the weld looks to be on Aluminium castings then 4043 is the filler I would choose as well, I find it to be a little more "user friendly" for castings.
If that was my 1st go at work I would be very happy with the results and so should you be.
Now just tell your boss you want to do all the tig work that comes in and go for it.

Thanks. We don't have much tig work at all to do. I balled it cause the one that was there was balled. It didn't seem right to me, but the guy that left was a really good tig guy. The balled thoriated doesn't work so well though LOL. It splinters/cracks at the ball. I thought my school welding teacher told me 5356 is better for cast. I remember welding some 1/16" cast stuff from home depot in school and 4043 wouldn't hardly bond. It worked out good so far on this cooler. Dave
