Discussions. 309L is ideal to join your stainless steel to mild steel because this welding wire is made to weld both metals. Stainless steel box section 30mm thick welding and sink bowl into the top frame. The strength of the joining is somewhat close to “normal” welding, the joining is permanent and can usually only be reversed by damaging the workpieces. By table of contents. About the book. However, this laborious process carried out at high temperatures is not suitable for all applications. Search in this book. It can be used for joining copper to steel at very high speeds. Thus, Porsche was forced to use stainless steel. Book • Second Edition • 1993 Browse book content. The joining of stainless steel and copper is necessary to manufacture these structures. Welding is still the standard technique for joining metals. You can weld a wide range of stainless steels, from 300 series stainless steels. Ni-/Co-base molten weld metal is comparatively “sluggish”, meaning it is not as fluid compared to carbon or stainless steel.
