Abstract
Nowadays technologies have huge assortment of welding processes are available and used in joining metals. The characteristics of the microstructures through weld zones, Scanning electron Microscope investigated the grain size before and after weld with the precipitates and the size and the extent of heat-affected zones (HAZ) will primary depend on: (1) the type of metals being joined, (2) the heat treatability of the material and welding velocity, (3) the classes of welding or joining processes used. The microstructure changes arising from welding will significantly affect the mechanical and the corrosion behaviour of the welded stainless steel. Because of lack of information which welding processes are the best method and the contradictory opinions regarding efficiency of different welding techniques. Accordingly, the present study has been undertaken to evaluate the mechanical and corrosion behaviour using different welding techniques, laser welding and conventional welding. Two welding techniques for Standard Austenitic stainless steel 1.4301(304) are presenting in this study: Case (I) gas tungsten arc welding (GTAW) or TIG; Case (II) High-speed remote scanner laser-welding.
