Abstract
In this study was to join and assess the development of gas tungsten arc welding (GTAW) on dissimilar materials like austenitic stainless steel and low carbon steel. This GTAW weld is best suited for the thin cross-section metals. This welding process can be used for continuous, spot or intermittent weld joints. The combination of mild steel and austenitic steel are used in various industries namely valves, furnace parts, tanks, heat treatment pots and baskets, kiln cooler plates. Tests were conducted effect of different welding process parameters on arc voltage, gas flow rate and torch distance. The mechanical properties and microstructures and the chemical composition of the joint of the gas tungsten arc welding joints will be examined using universal testing machine, scanning electron microscopy (SEM), energy dispersive spectroscopy (EDAX).
