ARC Welding Investigation On The Effect Of Independent Input Parameters On Welded Joint Strength Of AISI 1020 Carbon Steel

Quality and strength of welded joint mainly depends on mechanical and chemical properties of weld metal and heat affected zone in which are directly related to the type of welding and its independent input parameters. The response or output, ultimate tensile strength (UTS), were greatly influenced...
