Experimental Evaluation of Mechanical Properties and Microstructure of Friction Stir Welded 5083 Aluminium Alloy

Abstract

Friction stir welding (FSW) appears as a promisingly ecological weld method that enables to diminish material waste and to avoid radiation and harmful gas emissions usually associated with the fusion welding processes. Welding of non-ferrous materials like Aluminium, Magnesium, Copper etc, is difficult with the conventional welding processes as they are prone to oxidation effects. Hence we go for friction stir welding technique which makes use of a non-consumable welding tool to generate heat. Friction stir welding (FSW) process is a strong state welding strategy created by The Welding Institute (TWI) and now it is progressively utilized in Aluminum welding.KeywordsFriction stir welding, non-consumable electrode, solid state welding.
