TO OPTIMIZE PROCESS PARAMETERS OF TUNGSTEN INERT GAS WELDING OF MILD STEEL BY TAGUCHI METHOD

Mechanical Engineering

A Welding technique is defined as the process of joining two different or same metals by fusion process, with or without application of pressure and with or without use of filler metal. Welding of different or same material are depends upon various factors like the metallurgical changes, chemical changes , physical changes that occur due to welding, change in hardness of material, in and around the welding bed and the extent of wear and tear or we can say cracking tendency of the joint. Welding processes have been developed for change, so far using single or combination of factors like pressure, heat and filler material used.
