Potentiodynamic corrosion studies on laser beam welded austenitic stainless steel AISI 321

[摘要] In this study, the microstructure and corrosion characteristics of laser beam welded austenitic stainless plates has been studied. CO2Laser beam produced defect free weldments in AISI 321 with no trace of heat affected zone. The microstructural studies revealed distributed ferrites in the weld zone. Potentio-dynamic polarization studies were carried out on the weldments in 5% NaCl environment in order to understand corrosion current, potential and rate.
