About Resistance Rolling Welding Machine (Seam Welding Machine) Introduction
The upper and lower electrodes are pressed against the workpiece, creating a certain resistance under pressure, and continuously welding current through the workpiece, the welding current is passed through the workpiece to generate heat energy, which causes the two workpieces to reach the same melting point and welding, then pressurized and close-fitting, finally forming resistance welding.
Resistance Rolling Welding Machine (Seam Welding Machine) Features
- When welding the workpiece, increase the pre-pressure to eliminate gaps between workpieces and make them fit tightly. It does not require any filler metals and gases.
- Simple operation, low deformation of the workpiece, the fast welding process and does not require any high skilled operators or professional technicians.
- The power required to operate is less to ensure the safe and no pollution working environment.
- It is suitable for welding mode of mass production due to its fast welding speed.
- Through the preheated pulses melt the plasticity of the workpiece, softening it for a tight fit and prevent spattering.
How to operate the Resistance Rolling Welding Machine (Seam Welding Machine)?
The principle of double-sided, two-point overcurrent welding is adopted. When welding the workpiece, the upper and lower electrodes are pressed against the workpiece, creating a certain contact resistance under pressure. The welding current creates an instantaneous thermal welding and circuit at the two contact resistance points, without affecting the internal structure of the welding workpiece.
Resistance Rolling Welding Machine (Seam Welding Machine) Application
Resistance Rolling welding machine is used to weld electrical conductivity metal plate and metal mesh. It is commonly used for welding thinner sheet metal and its widely used in the automotive industry for its high welding strength, which provides sufficient strength for the body of the vehicle and is completed within seconds by seam welding mode. It is also applied for the Metal Products Manufacturing Industry, Military Defense Industry, Aerospace Industry, Drink Water Storage Barrel and Kitchen and Sanitary Supplied Industry,…etc.
