The effect of the current pulsation frequency on heat supply results during pulsed current TIG welding in 301L stainless steel

Main Article Content

Andrzej Kolasa


The paper presents the influence of pulsation frequency on the results of pulsed current TIG welding based on two criteria: geometric parameters of weld and changes in microstructure. The investigations were carried out for 301L austenitic stainless steel with constant current parameters, constant welding speed, 50% duty cycle ratio and constant heat input. The results were referred to the commonly used methods for measuring the amount of heat input.
