Hi all,
I lasercut a few more of the stainless practice cubes and tried an el cheapo pyrex gas lens.
I'm not sure if the increased coverage gave me less discoloration or if I was welding colder (or faster...). I tried to not remove too much of the material when welding.
I also added a max current control on my foot pedal which made the range more controllable.
It was really nice to see some pretty colours in the welds instead of the dull grey I have been getting.
I have my original cube and the one I did most recently. I don't think my filler feeding consistency is any better yet.

Certainly looks better, does your machine have the ability to pulse? You could use a slow pulse setting to help time the addition of filler and give a more consistent looking bead

Last weekend. Pressure vessel repairs. Didn’t include all the photos but ground out an old coupling and welded in a new one. Plus made a repair on another pin hole on the coupling on the left. With the pt test you can see the stress crack that developed on the edge of the HAZ. Had to grind that out full depth as well. Beveled the base metal and the coupling. Then had to add a fillet per code so that I didn’t have to back weld from the inside.

Yes it does have pulse just haven't really had a chance to fiddle in detail with all the settings. My Argon and scrap supplies are running low at the moment haha.
I think it is almost time to construct something a bit more useful :)

Some roots and caps. Never got to cap the other two welds they said they might have to cut it apart. Gotta love engineers! Oh well just means more fun welding for me.

Occasionally I talk them into letting me MIG weld. Yes it's cold but on these rec boats they want them to have the stack of dimes.

The bung is thick 6061 welded into 1/2" 5052. It's at an angle so the top is inset 1/4" and the bottom sticks out 1/8". Kinda tricky with lots of pedal play.

Some more seat risers. The blueprints called out 1-1/2" overall but when I gave them to them they said it should have been 1-1/2" in the center. Engineers haha oh well I get paid by the hour.ImageImageImageImageImageImageImageImageImage

Thanks bud and yes I weld the fillet first before I put the other piece on. Then I weld the top with the outside corner.

Big change of pace from the car parts and small tig stuff I'm used to! First pic is a floor for a roll off box we over build for our recycle glass plants, and the second is a frame for one of the local mills. Third/fourth pics are of a lifting hook for the bucket in the fifth pic, minus the 10 foot 4"plate arms that come up the side. So far in the last two months here I've mig welded a shit load, and ran dual shield, as well as arc gouged, all for the first time in any serious capacity. ImageImageImageImageImage

Nice projects! It’s amazing how much metal you can put down when you start working with thick stuff like that.
I have more questions than answers
