Some Helpful Features of the Tig Welding Process Using High Frequency Pulsed Arc

Abstract

Many of the features and advantages of TIG welding are well known. The paper presents in part the results of some experimental research using TIG welding with high frequency pulsed arc. A comparative study was performed between the application of TIG welding with high frequency pulsed arc technology and classical TIG welding, applied to achieve welded joints of stainless-steel parts. The conclusions are based both on the characteristics of the welding process (the hole main group of parameters) and the results of the applied non-destructive and destructive testing methods. Features like reduced deformations in the joint, low energy guaranteed ignition, wonderful focalization of the high current density arc, increased working speed and not the last, the special look of the welded plates recommends this procedure for some replacement possibilities for the expensive laser welding process. Aspects of improving the quality of welded joints are highlighted, given the low manufacturing costs.
