Looking for some feedback. We've successfully been GMAW welding A36 and A500 to SAE 1030 cast steel using ER70-S3 both CV Spray and modified pulse spray. Asides from the basic WPS parameter controlls we try to stay away from specilize control such as pre/post heat to save cost and training requirements. Recently we've been asked to explore welding A36 and A500 to SAE 1045 caststeel-now we just left the low carbon safety zone- The question is can we pull this off with only using the lowhydrogen variation to the GMAW process?

Feedback please. Anything to help.
