Jan 15, 2014 · 1. Arc-Welding Introduction Arc welding is the fusion of two pieces of metal by an electric arc between the pieces being joined – the work pieces – and an electrode that is guided along the joint between the pieces. The electrode is either a rod that simply carries current between the tip and the work, or a rod or wire that melts and ...sp.info How does the submerged arc welding process work?In the submerged arc welding process the flux-covered electrode is replaced by the granular flux and a bare electrode. An arc between the electrode and job is the source of the heat and remains buried under a blanket of flux. This flux keeps the atmospheric contamination away.See all results for this questionsp.info How is constant current used in arc welding?The constant current power is invariably used with SAW welding. Multiple electrode wire is used with ac and dc arcs. We use here the constant power system. It applies the constant voltage when the two-electrode wire is fed into the arc supplied from a single welding power source.See all results for this questionsp.info What do you need to know about welding consumables?Welding consumables Those to be used are as specified by the WPSs, are stored/controlled as specified by the QC procedure. Joint fit-ups In accordance with WPS/drawings tack welds are to good workmanship standard and to code/WPS. Weld faces Free from defects, contamination and damage.See all results for this question
