Seam welding is a metal welding that forms a permanent bond. During welding, the welding part is pressed between two welding wheels, and the rotating welding wheel drives the welding part and electrified. The welding current heats up through the local part of the welding part, forming overlapping welding spots to form continuous welds, and realizing permanent connection. Seam welder is widely used in box, such as automobile, motorcycle oil tank; Barrel body, such as oil tank and forming plate workpiece, such as rinm, muffler, radiator, etc.

2. Rolling welding head component: The rolling welding head box is made of chrome zirconium copper casting and processing as a whole. The rotating shaft conducts electricity through contact with the silver tile, resulting in higher conductivity efficiency. Internal water cooling is used near the conductive contact area to timely remove heat and ensure conductivity and service life.
3. Welding wheel drive mechanism: Powered by a reduction motor, the differential gearbox and universal spline shaft are used to drive both the upper and lower wheels simultaneously, while maintaining consistent linear speeds to avoid welding slippage.
4. The pressurization mechanism adopts vertical pressurization, and the electromagnetic valve is connected to the cylinder at the shortest distance, greatly accelerating the reaction speed of the action and improving production efficiency; The pressure guiding mechanism adopts self-lubricating bearings, which have good follow-up performance; Reduced the impact force of the electrode on the workpiece during pressurization, preventing damage to the workpiece and excessive depth of pits during welding, reducing electrode deformation and wear.
5. Pneumatic system: The solenoid valve, pressure regulating valve, air processor, etc. use branded products, and the cylinder adopts oil-free self-lubricating cylinder barrel. The equipment is equipped with a gas storage tank to stabilize the air source pressure. There is a pressure sensor at the inlet, which is monitored by PLC to prevent splashing, welding penetration, or cylinder failure during low air pressure.
6. Water cooling circulation system: Adopting parallel grouping cooling method, the transformer, inverter system and electrode head are cooled separately, and the heat generated during the welding process is carried away in a timely manner to stabilize the quality of the welding points and extend the service life of the electrodes and related components. A flow meter, ball valve, and water filter are installed at the inlet for easy observation and replacement of spot welding electrodes. When the water flow is insufficient, an automatic alarm is triggered to ensure the normal operation of the water cooling circulation system.
