Welding Unlike Sizes

[BradJacob]

This hasn't yet happened to me, but when welding unlike sizes of metal - let's say 1/8 plate to a 1/4 plate, do you weld at the smaller thickness setting to prevent burn-through? Or do you use the thicker size metal's setting? I'm inclined to think that you use the thinner metal's settings.

brad i just did that last week, i was using a mm250 set it at 5 and 5 and favored the 1/4

came out real nice.....no warpage !

i even suprised myself

use the setting for the heavier material and weld on that and push the puddle into the thinner material..

Yup, heavier setting and wash it into the thin stuff. Concentrate most of the heat on the thicker side, and allow just enough to wash over to make a sufficient bead with out burning through. It takes some practice and patience at times, but it really is easy.

Don has it, and is my philosophy as well whether mig or tig. Created a small pit of SS last week, had the bright idea to use 3/8" SS tubing for hinges on
the sch 10 tube, was a bear till I screwed my head on correctly, LOL
