Close-up view of a friction stir weld tack tool. The bulkhead and nosecone of the Orion spacecraft are joined using friction stir welding. Joint designs. Friction stir welding (FSW) is a solid-state joining process that uses a non-consumable tool to join two facing workpieces without melting the workpiece material.
For TIG/GTAW welding, the top side (front side) of a weld is normally protected by inert gas flowing through the welding torch and it is the underside (back side) of the weld where atmospheric gases need to be purged. When joining two parts together with a seal weld, it may be necessary to first hold them together, by making tack welds. [7]

Workers welding in parking garage. Welding is the main focus of steel fabrication. [8] Formed and machined parts are assembled and tack-welded in place, then rechecked for accuracy. If multiple weldments have been ordered, a fixture may be used to locate parts for welding. A welder then finishes the work according to engineering drawings (for ...
A portable spot welder. Spot welding (or resistance spot welding [1]) is a type of electric resistance welding used to weld various sheet metal products, through a process in which contacting metal surface points are joined by the heat obtained from resistance to electric current.
