Performance of Welding Characteristic Inaluminium Alloy 5052 Using Gas Tungeston Arc Welding

In this experimental work, aluminium alloy (5052) weldments were made using Gas Metal Arc Welding (GMAW)with pulsed current and non- pulsed current at different frequencies 2Hz, 4Hz, 6Hz. Non-destructive tests like radiography, liquid penetrate test were conducted, evaluated and compared with pulsed and non-pulsed current welding at different frequencies of thickness materials (2mm of 5052 aluminium alloy). The aim of this experimental work is to see the effect of pulsed current on the quality of weldments. The experimental results pertaining to different welding parameters for the above material using pulsed and non-pulsed current GMAW are discussed and compared.
