15 kVA Multi Spot Welding Machine

The process of spot welding is joining of the two surfaces with the heat production from resistance to electric current. In this process, two metal surfaces are placed together under the pressure of copper alloyed electrodes. The electric current is passed through these electrodes and the heat is produced due to resistance. This heat production due to resistance melts the spot area thus joining of the two surfaces with spot without heating the remaining surface of metal.

The amount of heat generated at spot depends upon the magnitude of resistance which is determined by current magnitude and duration of time. The too less heat will not produce good spot welding and two high heat will lead on to burn off the surfaces leading on to hole formation.

This welding set of spot welder is especially needed in all forms of automobile industry where it is used universally to weld sheet in making car while in automobile industry the robotic spot welder is used even. The portable spot welding is also used in orthodontics clinic for resizing of a molar band. The other application of the spot welder is to strap nickel- cadmium or nickel metal hydride to make batteries. The spot welding is used for metal sheet and wire mesh, aluminum metals, sheet, buckets, utensils etc.

The portable spot welding machine is a domain of the cruxweld in resistance welding.
