Experimental study on Pulsed and Non- Pulsed Current TIG Welding of Stainless Steel sheet(SS304)

A.Raveendra, Dr.B.V.R.Ravi Kumar

In this experimental work tests were conducted on the weldments of SS304using GTAW with pulsed current and non-pulsed current at different frequencies of 5Hz,&10Hz on 3mm thick sheets. Hardness test, tensile test and microstructure results of weldments were studied . The aim of this experimental work is to see the effect of pulsed current on the characteristics of weldments. The experimental results pertaining to different welding parameters for the above material using pulsed and non-pulsed current GTAW are discussed and compared.
