Abstract
In this study, Activated Tungsten Inert Gas welding (A-TIGW) operation factors welding current, speed and argon gas flow rate (AGFR) were optimized in order to attain the enhanced wear resistance of weldment which is obtained by welding of AISI 316L austenite stainless steel. The levels of welding factors were optimized using Taguchi method. Contribution of welding factors on the wear resistance was determined by using ANOVA technique. Dry sliding wear resistance of weld joint against EN-8 steel was studied employing wear test rig at constant load, sliding velocity and sliding duration at room temperature. The results of the experiments illustrated that as the welding current and speed raises, the wear of the welded joint tends to drop. Experimental results showed that welding factors have to be investigated suitably to attain the enhanced wear resistance.
