This is all in my WPS, so....
At or over 1/8th I preheat to 200 degrees with an inter pass limit of 250 degrees, and stress relieve, and still use the ER80 .
I do use ER-80s-D2.
You can do whatever you want, but under 1/8" I don't preheat or stress relieve .

I want to make an exhaust pipe hanger from a piece of 3/8 4130 tube,
can I cold form it or do I have to heat it with a torch?
Want to flatten each end.

Flatten part way, add the insert, flatten the rest of the way and edge weld the end..
Access to welding equipment a .050 insert in the end adds a lot of strength.

Quick question. Im not discussing on locations on welding in gussets, but instead exactly how to weld them in. On round tube frames, should I weld the gusset plates in the center of the tubing or on the side of the tubing?
Thanks. 1990 Suzuki LT250R Quadracer...

Two weeks ago I had my fuselage sandblasted and coated with two-part
epoxy. I had to get it primed prior to welding because it's going to
