Optimization of Weld Bead Width in Tungsten Inert Gas Welding of Austenitic Stainless Steel Alloy

This paper investigates the effects of process parameters on weld bead width of austenitic stainless steel SS-310 in tungsten inert gas welding. The four parameters namely welding current, type of gas, gas flow rate and included angle of weld plates during butt joint were varied at three levels. The DOE approach was used to design experimental conditions. Orthogonal array L9 was used for carryi...

Evaluation of the Melted Zone Microstructure in the Interface of the Dissimilar Weld between A335 Low Alloy Steel and ER309L Filler Metal by Gas Tungsten Arc Welding

In the present study, the microstructure and mechanical properties of the dissimilar welding between ASTM A335 low alloy steel and ER309L austenitic stainless steel were investigated using the gas tungsten arc welding process. The welding of dissimilar materials between ASTM A335 low alloy steel and ER309L austenitic stainless steel was found to have a significant effect on the microstructure w...

Modeling of Transport Phenomena in Gas Tungsten Arc Welding of Ni to 304 Stainless Steel

This study investigates transport phenomena in the weld pool (WP) of gas tungsten arc (GTA) welding of Nickel to 304 stainless steel. A finite element 3D simulation of fluid flow and heat transfer of spot welding without consumable is accomplished which leads to prediction of the weld zone shape, weld penetration and dilution of alloying elements. The model includes magneto-hydrodynamics (MHD),...

Gas tungsten arc welding

Gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG) welding, is an arc welding process that uses a nonconsumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by a shielding gas (usually an inert gas such as argon), and a filler metal is normally used, though some welds, known as autogenous welds, do not require it. A const...

Stainless steel manual metal arc welding fumes in rats.

Forty two male Wistar rats were exposed to manual metal arc (MMA) stainless steel (SS) welding fumes generated by an automatic welding device for "nose-only" exposure. The exposure simulated an actual MMA/SS welding environment as closely as possible. For the retention study, the duration of exposure was one hour per workday for one, two, three, of four weeks and for the clearance study four we...
