How many different welding processes are in use?

There are basically five types of welding namely:a)Gas Metal Arc Welding (GMAW/MIG)b)Friction welding,c)ELECTRON BEAM WELDINGd) LASER BEAM WELDINGe) RESISTANCE WELDINGWhat is welding?Welding is a fabrication process in which two or more parts are joined together using of heat, pressure, or both to form a joint as the parts cool. materials to be welded include metals, thermoplastics, and wood.Types of welding processesa)Gas Metal Arc Welding (GMAW/MIG)Used mainly for joining metals like stainless steel, nickel, copper alloys, aluminum, titanium, and cobalt.b)Friction welding This is a  technique used to join materials using mechanical friction. this can be used to join wood, steel, and aluminum.c)ELECTRON BEAM WELDINGThis process uses a mean of high-velocity electrons to combine materials this can be used to join thick sections in the aerospace, automotive, rail, and nuclear power industry.d)LASER BEAM WELDING this is used to combine pieces of metal or thermoplastics.e) RESISTANCE WELDING This is a process that joins metals by applying pressure and passing a current through them for a period of time.
