Magnesium welding?

admin

A question came up on another forum and I don't know the answer.  Can magnesium be welded with mig? I've welded it with tig, but never heard of welding with mig. Just wondering if it can be done?Yeah, I know, but it'll be ok!Lincoln Square wave 255Miller Vintage mig30a spoolgunThermal Dynamics Pacmaster 100xl plasmaSmith mc torchEllis 1600 band saw
Reply:Magnesium and aluminum  can be TIG'd with AC. I know ally can be MIG'd with argon and  DC CV and spool gun. So, I would think if they sell wire and a capable gun to feed mag then , probly yes on DC CV and argon.

Reply:Magnesium can even be O/A welded with the correct flux. If that flux still is available is a diffrent matter.

Reply:They actually sell in aluminium alloy .035 wire made by blue demon which has magnesium in it so I think that might work it's for aluminumSent from my SM-G935P using Tapatalk
