    The Welding of Stainless Steels

    Since the SAW process is used mainly for thick austenitic stainless steel sheet, par- ticular care must be taken to avoid the for- mation of sigma phase due to the use of high welding energies. This is especially the case for 25% Cr – 20% Ni alloys, but also for 18% Cr – 9% Ni grades with high ferrite contents.
