State Some Mechanical Properties for Al- Alloy Welded by Seam Welding Technique

Abstract

The aim of this paper was perpetrated lap joint welding samples welded by seam welding method ,2014 heat treatable aluminum alloy, the paper studied some groups at different variable welding, welding time was studied at electrode pressure 1,1.5 KN with thickness 1.5 mm and another group at 2 mm. after welding process shear strength, Vickers hardness were tested at different variables. The paper stated the best shearing strength at 1.5mm thickness with 45 KA welding current at 1.5 KN electrode pressure. Increase 0.5 mm in thickness lead to decrease 20% of shearing strength.
