I have been welding Mild steel with ER70-S6 and chromoly with ER70-S2. I understand that Er80-s2 (?) is the recommended rod for 4130 chromoly tubing.
Is there any negative effect of using the ER80...rod on mild steel?
I'm just wondering if it's possible to use one rod for both mild steel and chromoly without any negative strength effects on either?
Maybe this should be asked a different way...
What filler rods should be one have on hand for different materials...most commonly used?
Lastly, I understand that some welders choose a silicon-bronze rod for Tig welding sheetmetal to limit heat input/warpage. What is the numerical designation for this wire?
thanks
