What are the factors that affect the welding industry?

Another factor affecting productivity of welders relates to the deposition rate of the welding process. The higher current processes have the highest deposition rates, thus the submerged arc welding process and the electroslag welding process will remain important as costs must be reduced. The next factor deals with increasing material costs.See all results for this questionsp.info Why is active flux used in submerged arc welding?Further, when an active flux is used in submerged arc welding (SAW), the number of weld passes to be applied in a joint is limited. This is since there is a tendency for alloying elements (such as Si and Mn) to build up during multi pass welding, which deteriorates the fracture toughness values in the final weld pass.See all results for this questionsp.info Investigation of the Effects of Submerged Arc Welding ...Jan 01, 2017 · Welding parameters such as current, voltage, wire feed rate, and electrode extension length are the principal parameters of submerged arc welding (SAW).
