摘要
Micro Plasma Arc Welding (MPAW) is one of the important arc welding process commonly used in sheet metal industry for manufacturing metal bellows, metal diaphragms etc. In the present paper welding of AISI 304L austenitic chromium-nickel stainless steel using pulsed current micro plasma arc welding was discussed. The paper mainly focuses on studying the weld quality characteristics like weld pool geometry parameters, microstructure, grain size, hardness and tensile properties of Pulsed Current Micro Plasma Arc Welded AISI 304L austenitic stainless steels at different welding speeds. Results show that a welding speed of 260 mm /minute yield better weld quality characteristics.
