Hi! What a wonderful site! Just ordered 12m of polished 316 grade Stainless tube. The size is 25mm o.d. and wall is 1.5mm. I have also bought some 316 mig wire and some argon gas. I have done some welding in the past but never on stainless - any tips, useful websites, etc? Specifically - is it just like welding the same thickness in mild steel?
