What is the preferred shielding gas for hardened steel to cast iron? Wire is the equivalent of ni99 rod. I have 100% argon and stargon®cs on hand, but will get whatever is needed. Job will be done using a miller 350p.
This "HOT" nightmare was thrown in my lap friday afternoon.
The job consists of welding three pressed in 15mm dowel pins to the casting. In my opinion this is a band aid for a bad design.
The customer has specified using mig. I suspect this is because of the number of pieces that need to be done ( a couple hundred at least). I tried getting them to let me stick or tig them but no go.
Any and all help is appreciated.
