Hello, I am wanting to try a piece of san mai with a carbon steel core and stainless jacket. I have seen others make the stack then weld all the way around the outside to keep the stainless from decarbing on the inside. What type of welder is used to weld the stainless to the high carbon steel? I have an arc welder, but not sure that will work. Is a tig or mig normally used for this? I have also seen stainless steel rod for the arc welder and I wondered if that would work.
Also to forge weld the stainless to the carbon I am assuming temps need to be higher than weld carbon to carbon.
I am in the market for a new welder and I am thinking strongly of buying a combo welder that does arc/mig/tig. Anyone have any experience with these?
Any help would be appreciated.
Thanks, Shane

I can help with that if you want. There are some top shelf welders here but I can run you through your options. I have been in the business for 20ish years. Its easier to text or talk, there are a lot of options and budget matters. Storm 360.305.6225
