Parametric Optimization of TIG Welding Process in Butt Joining of AISI 310 Austenitic Stainless Steel Materials
Abstract: Tungsten inert gas (TIG) welding is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. Selection of the levels of the input parameters plays a very significant role in determining the quality of a weld joint. The present study is planned to investigate effects of process parameters: welding current, gas flow rate and arc gap on ultimate tensile strength in TIG welding of austenitic stainless …

Statistical Analysis on Weld Bead Geometry of Pulsed Current Micro-plasma Arc Welded AISI 316Ti Austenitic Stainless Steel Sheets
Abstract: Micro-plasma arc welding (MPAW) uses low amperage to join sheets, where the thickness is low, such that they can be used for manufacturing metal bellows, metal diaphragms etc. In the present work, pulsed current MPAW is used for joining 0.3 mm thick AISI 316Ti austenitic stainless steel sheets. Peak current, base current, pulse rate and pulse width are considered as input parameters and weld bead geometry parameters namely front width, …

Effect of Pulse Current Micro Plasma Arc Welding Parameters on Pitting Corrosion Rate of AISI 316Ti Sheets in 3.5 N NaCl Medium
Abstract: Austenitic stainless steel sheets are used for fabrication of components, which require high temperature resistance and corrosion resistance such as metal bellows used in expansion joints in aircraft, aerospace and petroleum industries. When they are exposed to seawater after welding they are subjected to corrosion as there are changes in properties of the base metal after welding. The corrosion rate depends on the chemical composition of the base metal and …
