4130 Filler Rod
Our filler rod for 4130 Chrome Moly is NOT 4130 alloy. Rather, we offer what engineers, welders, and experience shows to be the best choice for welding structures of tubing and sheet: ER70S6.
I know we recommend something a little different on the 4130 Airframe Video, but I can't help making little improvements as I discover them, or as they become available. So it is in this case. This filler has great penetration and little spatter, flows evenly, and is reasonably priced.
(NOTE: DO NOT use 4130 alloy filler unless you wish to heat treat the whole welded assembly when done.)
