A Study Of Spot Welding Conditions At The Welding Region Of The Duralumin Alloy

Abstract

In this research the spot welding parameters ( welding time , welding electrode force , welding current ) have been studied by determining the tension test of duralumin alloy , type (H.15) which have a common use in the cars and air plain industry . The results showed that the best shearing strength was at (12) cycle of welding time , (2) KN welding electrode force and (50) KA welding current . Also, it was found that the shear strength decreased with the increasing of metal thickness at fixed welding condition up to (50) KA welding current
