4130 tubing as filler?

Aug 18, 2005 3 Replies

Googling around for sources of scrap 4130 I found the following statement: "Call me a butcher, but I'd use scrap 4130 as filler. It's usually easier than finding the correct rod" -



Is this idea more trouble than it's worth? I'm assuming he makes 1/8" strips from tubing - Mike

Buy ER80S-B2. It is the best TIG filler rod for 4130.

Short answer yes with a provision; if this involves any code, injury from failure then the answer is no. Welding rods have additives such as deoxidizers that are required for a sound weld. Just found this pdf that may be of interest to the group

Yes, its more trouble than its worth. S2 or S6 rod is just fine.
