Optimization of Submerged Arc Welding Process: A Review

2015-3-16 · Wire sizes normally used for butt welding are 2.0, 2.5 and 3.0 mm, with wire separations of about 8 mm. DC welding, with the wire positive relative to the workpiece, is preferable, as this results in the best arc stability and least risk of porosity. When hard facing using tubular wires, it is generally preferable for the wire to

Welding - Wikipedia

2019-4-23 · Welding is a fabriion or sculptural process that joins materials, usually metals or thermoplastics, by using high heat to melt the parts together and allowing them to cool causing fusion. Welding is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal.
