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),...

متن کاملStainless 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...
متن کاملSelection of Arc Welding Parameters of Micro Alloyed Hsla Steel
Like all steel types, HSLA requires a definition and strict practical adherence to welding parameters in order to achieve the required weld quality. Different sources offer a varying array of welding parameters. Although their hierarchical importance can be disputed, their principal definition and practical adherence are prerequisites for the quality of welded joints 1,2 . The analysis of earli...
متن کاملBlue-light hazard from CO2 arc welding of mild steel.
OBJECTIVES The objective was to quantify the blue-light hazard from CO(2) arc welding of mild steel. METHODS The spectral radiance of arcs in CO(2) arc welding of mild steel was measured for solid and flux-cored wires at welding currents of 120-480 A. Effective blue-light radiance and the maximum acceptable exposure duration were calculated from the spectral radiance using their definitions i...
