Friction stir spot welding creates spot welds are created by pressing a rotating tool with high force by two sheets within the lap joint. The frictional heat and pressure plastify the workpiece, so that the tip of the pin...
Spot welding is a joining process whereby metal surface points are joined by heat generated from resistance to electric current.
Submerged arc welding is a welding process developed and patented by Jones, Kennedy and Rothermund, and requires a continuously fed consumable metal cored electrode. The molten weld and the arc zone are protected by being submerged under a flux...
Brazing is a joining process in which two or more items are bound via a filler metal flowing into the joint. The filler material has a lower melting point than the target.
