Abstract

The paper presents the effects of tungsten inert gas (TIG) welding of 4 and 10 mm thick austenitic stainless steel EN X5CrNi1810 (AISI 304) in the butt joint with and without active flux. The sample dimensions were 30050 mm. The commercially available active flux QuickTIGTM, which does not contain health hazardous ingredients, was used for testing. In the planned study the influence of welding position and weld groove shape was analysed based on the penetration depth. A comparison of microstructure formation, grain size and ferrite number between TIG welding and active flux TIG (ATIG) welding was done. The A-TIG welds were subjected to bend test. A comparative study of TIG and A-TIG welding shows that A-TIG welding increases the weld penetration depth, they have good bending properties, and ferrite number slightly increases.
