Optimization of hardness of weld in submerged arc welding

Materials Today: Proceedings, 2020
Abstract If a high quality of welding joint in thick metal is required, submerged arc welding process is preferably used. There are several welding input process parameters which influence the quality of the weld. Some important input process parameters in the case of submerged arc welding process are welding current, welding voltage, wire feed and ...

Thermal model of submerged arc welding

Materials Science and Technology, 1992
AbstractA model for calculating the temperature field in submerged arc welding is presented. The algorithm is based on the method of elementary balances. Melting of the electrode rod and melting of the parent material followed by solidification of the pool of molten metal are considered. The calculated temperature evolution curves are compared with the

Submerged Arc Welding

1993
Abstract Submerged arc welding (SAW) is an arc welding process in which the arc is concealed by a blanket of granular and fusible flux. This article provides a schematic illustration of a typical setup for automatic SAW and discusses the advantages and limitations and the process applications of SAW.

Inclusion effects on submerged-arc weld microstructure

Journal of Materials Science, 1987
Bead-on-plate welds were produced using twenty four fused reagent grade submerged arc welding fluxes, selected from three flux systems, SiO2-MnO-FeO, MnO-CaF2 and SiO2-CaO-CaF2. The welds were processed using AISI 1010 steel coupons, and a Lincoln L-50 AWS type A5.17) welding wire with a constant heat input of 3.0 kJ mm−1.
