Resistance welding applications

Resistance welding is a welding method that uses the resistance heat generated by an electric current passing through the contact surface of the workpieces to locally heat the metal to a molten or plastic state, while applying pressure to achieve a connection. It belongs to the category of pressure welding and mainly includes four types: spot welding, seam welding, projection welding, and butt welding.

Resistance welding is widely used in many industrial fields. Here are some typical application examples:

Automotive Manufacturing: Body welding: Used for welding parts such as doors, roofs, and side panels to achieve high-strength connections.

Battery Packs: Welding lithium battery tabs and busbars to ensure conductivity.

Home Appliance Industry: Washing Machine/Refrigerator Housings: Welding thin steel sheets to form a sealed structure.

Aerospace: Aircraft Fuselage: Welding aluminum alloy parts to reduce weight while maintaining strength.

Other Fields: Bicycle Rim: Welding rims and spokes.

Boiler Pipes: Welding pipe joints to withstand high pressure.

Due to its high efficiency and energy-saving characteristics, resistance welding plays an important role in joining thin sheet metal.
