You won't be able to put enough heat into the subframe to warp it, as the edges are really thin.

When I did mine, I used a pulse setting to keep the heat down. Prepped first by using a buffing wheel across the seams and above/below about two or three inches. Then, I laid a small bead, about an inch long. Moved the frame 90 degrees to the next side and laid down another small bead. Moved again, small bead. By the time I'd get back to the first bead it had cooled down and I just tied in another inch and moved to the second bead. Repeat until the seams are as sealed as possible (while leaving some spots for drainage). Then I cleaned up the edges with an abrasive wheel so it looked tidy and finally buffed the spatter clean.

Thanks, that’s kind of what I was thinking, hadn’t thought about the pulse setup... but I’ll do some testing.

Love the attention to detail. Hopefully my engine bay will look that go soon.

Keep up the good work!

What kind of paint/coating are you using after welding?

I am just planning on using POR 15.

That the route I took as well.

I've heard that it adheres better if there's some surface rust, any truth to that?

I’ve always had good results with “slightly” rusted surfaces, the POR 15 tech documents suggest, rusted, seasoned or sand blasted metal for best adhesion - they also have a metal prep that I have used on brand new steel... so for the subframes and all of the suspension components I just use a scotch brite pad, then a quick wipe with lacquer thinner for a final clean...

Ended up re doing my seam welding, didn’t like the first result, struggled with getting enough heat... much better round 2.
