Abstract

In this study, 10 mm thick DUROSTAT 500 and AISI 430 grades were joined by double sided keyhole tungsten inert gas (K-TIG) welding method without using filler material. The characterization of the microstructure of the weld zone was investigated by optical analysis methods and the mechanical properties of the welded parts were examined by mechanical tests. The fracture surface structure of the parts that were broken as a result of the tests were examined. No deterioration was observed in the welded samples. It was determined that the weld penetration increased as a result of the increase in the amount of heat entering the weld zone with the increasing welding current.

Keywords: AISI 430; DUROSTAT 500; K-TIG; microstructure; weldability
