Technological Conditions of Mechanised TIG Welding using Various Systems Adjusting Current and Electrode Wire Feeding Parameters

The study described in the article involved technological tests of mechanised TIG welding with an electrode wire fed at a possibly low angle in relation to a welding arc and based on various wire feeding control systems, e.g. enabling the adjustment of wire feeding rate pulsation and synchronisation of wire feeding rate with current impulses. The article also presents differences in sets of technological parameters of welding performed using such control systems.
