An overview of TIG welding of Ti6Al4V: Recent developments

Abstract

Titanium is a commonly used non-ferrous metal in the aerospace, chemical and nuclear industry, due to its unique structural and mechanical properties. Selection of suitable welding techniques and understanding of the effects of parameters corroboration to achieve a quality joint necessitated this article. The article presents recent researches in process parameters optimization done on Tungsten Inert Gas (TIG) welding of Ti6Al4V alloy. Furthermore, it discusses the effects of the parameters used in TIG welding technique on the weld quality, mechanical properties, and microstructure of joined plates. Pulsed TIG welding was found to be the most suitable type of welding for Ti6Al4V alloys based on its ease of use and reduced heat input compared to the conventional TIG welding.
