ABSTRACT In this study, two different welding methods as TIG and TIG Pulse are used for joining 304 series stainless steel
sheets having 2 mm thickness. In preparation of welded specimens were used three different welding currents ranging from 70
A to 110 A by rise of 20 A.. The microstructure differences of the weld joints obtained by using two different welding methods
and three different welding currents were investigated. Tensile specimens prepared according to standards were exposed to
tensile testing at as speed of 20 mm/s. Fracture surfaces obtained from tensile test of welded specimens were examined and
their mechanical properties were compared.
