The formability of butt welded stainless steel sheets was investigated through Erichsen cupping and deep drawing tests.
In the case of austenitic stainless steel SUS304, even TIG Welded sheet with wide fused zone showed the same degree of formability as that of base material, taking care against lubricant. In the case of ferritic stainless steel SUS430, the EB welded sheet with narrow fused zone was better than that of TIG welded, sheet. The formability of welded sheet of modified SUS430 with lower C and with ferrite-forming element was nearly equal that of base material.
