Technique of Submerged Arc Welding (SAW) | Industries | Metallurgy

It is an automatic process developed primarily for the production of high quality butt welds in thicker steel plates. SAW differs from other arc-welding processes in a way, that a blanket of fusible, granular material (flux) is used for shielding the arc and the molten metal. The deposition rate in this process is high and penetration is deeper. In this [...]

Technique of Thermit Welding | Metals | Industries | Metallurgy

Thermit welding is the only welding process employing an exothermal chemical reaction for the purpose of developing a high temperature. It is a fusion process in which weld is effected by pouring super-heated liquid thermit steel around the parts to be united. The heat of “thermit” reaction is utilised to bring the surfaces of metal to be welded into plastic [...]
