Abstract:
In this Paper we discuss about the distortion and material consumption of 409M ferritic stainless steel for the process of TIG and SMAW welding. As with other welding processes such as gas metal arc welding, shielding gases are necessary in GTAW or MIG welding is used to protect the welding area from atmospheric gases such as nitrogen and oxygen, which can cause fusion defects, porosity, and weld metal embitterment if they come in contact with the electrode, the arc, or the welding metal. The gas also transfers heat from the tungsten electrode to the metal, and it helps start and maintain a stable arc. We used the TIG and SMAW process to find out the distortion created by welding at different current and comparative study in between two welding.
