Plasma Arc Welding (PAW) for Duplex Stainless Steel 2205

[MrTungsten]

Hi Expert

Is there anyone have some experience with Plasma Welding for DSS 2205 , we want to weld long seam liner of 3mm thickness 2205 DSS Material.

Is there anyone know about the suitable composition of Plasma Gas and Shielding Gas for DSS ? . Commonly we use mix gas with Ar + H2

Thanks for all your knowledge and experience

Regard's
