Spot Projection Welders

Spot projection welders are resistance welding machines. They join metal components. The process combines spot welding and projection welding. Projection welding involves raised areas on one or both parts. These raised areas are projections or embossments. During operation parts go between two flat copper electrodes. Electricity flows and the projections get hot. Heat and pressure join the parts at determined points. Melting occurs locally. This creates welds that are consistent. In comparison to spot welding, projection welding uses the part's shape to direct current. The workpiece geometry allows several welds at the same time, if projections are present. For example attaching nuts, bolts as well as studs to sheet metal is effective with these welders. The automotive appliance next to construction industries use them frequently. Capabilities include welding thick materials. The process makes multiple welds at once. Joints are cleaner. They are more pleasing to look at. Electrode wear is low. The weld strength also dependability are appreciated.
