What is Spot Welding? Complete Guide to The Process
Spot welding is a type of resistance welding that uses heat generated by electric current to fuse the two pieces of metal together. In this process, two electrodes are placed on either side of the metal pieces and an electric current is passed through them to create heat. This heat melts the metal and causes it to fuse together.
A comparison of resistance spot weld quality assessment …
Resistance Spot Welding (RSW) is used in many different manufacturing industries to join sheet metal components due to its quick cycle times, low cost, ease of implementation and adaptability to different joint configurations and materials. However, quality variation in spot welding can affect both the functionality and safety of products.
Review of Electron Beam Welding Technology in Space …
