Tig Welding 4140 to 1045

This weekly video is about Tig Welding 4140 Steel to 1045 Steel.

The customer supplied a drawing to modify 20 snap ring pliers and weld some jaws on the end that were machined out of 4140.

Inconel 82 tig rod was used because I have had a lot of success with inconel 82 in repairing tool steel injection molds.

312 stainless would have been my first choice, but I had the inconel 82 rod in storage and in the right diameter… so I used about 3 rods to complete all 20 parts.

What rod would you have used?
