Help Please. T-Joint. Melting Holes
Hello welders of Reddit. I am having a problem welding a T-Joint. I’ve got two pieces:
- 30” length of square tubing that’s 3/16” thick.
- 8” piece of square tubing that’s 1/8” thick.
I’m trying to weld the end of the 8” length to the center of the 30” piece — a butt joint — basically creating a “T.”
I’m using 3/32” 7018 electrodes and running at the lowest my autoset will run at (manually cranking power down to 60A for 1/8” steel and 3/32” rods).
I’m approaching the weld at a 45 degree angle, and dragging the welding rod by 15 degrees.
I am burning holes in the 1/8” thick tubing.
As I’m typing this, It occurred to me that I have my ground clamped to the 8” piece and not the 30” piece to let current flow through the joint I’m trying to weld. Fuck me. Did I just figure it out? Today, I went out and bought 3/16” for both pieces.
Any thoughts/tips/suggestions for me?
Here’s a pic. And I did grind the paint off the 30” length. :-)
