Welding SCM415 to 4130 Chromoly

[Black Rainbow]

G'day. I'm having a new electric cargo bike frame welded and I'm in the process of buying all the materials for it. The rear dropouts I'm looking at are made of SCM415. https://www.otaisteel.com/products/quenched-and-tempered-alloy-steels/jis-scm415/

The frame will be made of 4130 Chromoly tube. My question is are both these materials able to be welded to each other successfully?

Yes you can do this with a wire of: CLASSIFICATIONS / CLASSIFICATIONS EN ISO 21952-A: W CrMo1Si SFA / AWS A5.28: ER80S-G weld well.

I’d recommend an undermatching filler wire personally.
