In this study, the effect of various welding parameters on the weldability of Mild Steel specimens having dimensions 50mm× 40mm× 6 mm welded by metal arc welding were investigated. The welding current, arc voltage, welding speed, heat input rate are chosen as welding parameters. The depth of penetrations were measured for each specimen after the welding operation on closed butt joint and the ef...

The objective of this study was to characterize personal exposures to welding-related metals and gases for production welders and non-welders in a large manufacturing facility. Welding fume metals and irritant gases nitrogen dioxide (NO2) and ozone (O3) were sampled for thirty-eight workers. Personal exposure air samples for welding fume metals were collected on 37 mm open face cassettes and ni...

Resistance welding of crossed wires, e.g. used in the electronics industry or fabrication wire meshes, is analyzed by both experiments and numerical modeling using an electro-thermo-mechanical finite element formulation. Welding machine characteristics are discussed necessary requirements to type concluded. Cross-wire stainless steel, structural steel aluminum presented, differences process fla...

During tungsten inert gas welding process, arc length will change due to thermal deformation, uneven surface of workpiece and electrode loss. Considering the large fluctuation in all-position annular seam under action multi-variable coupling, a mathematical model voltage was established this paper, an isolated high frequency acquisition circuit designed. An improved sliding filtering algorithm ...

Laser beam welding has wide acceptability due to least welding distortion, low labour costs and convenient operation.
