    How To Weld 4140 Steel WELDING ANSWERS

    Developing Welding Procedures for 4140 and Other High Carbon Steels. ER70S-2 can be used but you will be undermatching the base material. Low-hydrogen electrodes minimize the amount of diffusible hydrogen in the weld. With the elevated carbon content even low levels of hydrogen can wreck havoc. A common problem with medium to high carbon steels is their susceptibility to hydrogen-induced cracking.

    Welding 4140 and Other Tips - Welding Tips and Tricks

    Welding 4140 is a lot like welding 4130 which is a lot like welding plain old steel. Except for being more crack sensitive and therefore needing a preheat before welding on certain applications, the puddle looks very much the same as welding plain carbon steel... thats because the composition is so similar. 4130 and 4140 are low alloy steels.
