SOME EXPERIMENTAL INVESTIGATIONS ON LASER WELDING OF AISI 904 L STAINLESS STEEL JOINTS

摘要：

Laser beam welding experiments have been carried out on 3 mm thick super austenitic stainless steel specimens in butt-joint configuration.The experiments were conducted according to the central composite design approach.The laser weld bead profiles mainly depends on various parameters such as beam power (BP),travel speed (TS) and focal position (FP) of the laser spot and types of shielding gas.These parameters are to be selected suitably to obtain the desirable output.The bead profiles were measured using optical microscopy.The laser weld joints were tested through tension test,impact test and hardness test.Microstructural studies were also carried out.
