OPTIMIZATION OF PROCESS PARAMETERS FOR VIBRATION ON MECHANICAL PROPERTIES OF DSS 2205 DURING TIG WELDING

Abstract: This research work emphasizes on the improvement in mechanical properties and provide the best combination of welding parameters to produce sound welds by the imposition of mechanical vibration during TIG welding of the DSS 2205 material. Gas tungsten arc welding (GTAW) or tungsten inert gas welding (TIG) is an electric arc welding process in which a non-consumable tungsten electrode is used to produce the weld, an inert shielding gas (argon or helium) is generally used to protect the electrode from atmospheric contamination. This research provides the information about the problem of tensile strength reduction of DSS (duplex stainless steel) due to TIG welding. In the present work, an experimental investigation has been carried out in an industrial setup to determine and record the responses of the mechanical vibration applied for the TIG of DSS 2205 material under different parameter conditions.We have used mechanical vibration technique that uses low frequency vibrations to relieve residual stresses in weldment.In the industries, metal joints are mostly used in the form of a structural material for different manufacturing applications because it yields high strength and corrosion resistance.... -view more from following pdf link
