Abstract
In this experimental work, aluminium alloy (5052) weldments were made using Gas Tungsten Arc Welding with pulsed current at different frequencies 2Hz,4Hz,6Hz. The selected material as Aluminium plate and electrode is taken into chemical analysis test for checking proper composition of materials. With the successful results it is subjected to made weldment with chosen parameters. Non-destructive tests like radiography, liquid penetrate test were conducted, evaluated and compared with pulsed welding at different frequencies of two different thick materials (2mm and 3mm of 5052 aluminium alloy).The aim of this experimental work is to see the effect of pulsed current on the quality of weldment. The experimental results pertaining to different welding parameters for the above material using pulsed and non-pulsed current GTAW are discussed and compared.
