Tig Weld 3D Printed 15-5PH part to 4130

General Discussion

Hi All,

I need to join a SS 15-5PH 3D printed (by RAM 3D) part to a 4130 Pinion Bridge and am planning to Tig with Weldmold 880 (or 312) filler wire. Does anyone have experience with this or have any suggestions for an alternative filler material?

Cheers,
Shane

I would probably go with 309L based on previous advice I have been given. I just did a quick google and it has greater elongation and less carbon vs 312 so maybe that is why? No actual experience though

A Pinion bridge and a 3D-printed part sounds like an interesting combination! If you’re willing to share photos, that would be nice.

Thanks! Did a bit of research myself as well and came to the same conclusion.

I’ve designed some bigger chainstay landing tabs to replace the standard features on a Pinion bridge. I’ll definitely post some photos once they are in place.

That has been my experience as well. Joining the CS tubes to the mount requires a lot of work.
