Classification
This Seam Welding Machine is classified as follows:
By power source: AC and inverter DC
By welding wheel orientation: Horizontal and longitudinal
By quality grade: Top quality and simple type
Features
1.Equipped with a 3-phase variable-frequency motor, delivering stable welding speed, easy adjustment, and consistent operation.
2.Welding circuit loop adopts internal water cooling, while welding wheels (electrodes) use external water cooling.
3.Conductive rotating components feature embedded silver bushings; the conductive base is sealed oil-lubricated and water-cooled to ensure flexible rotation and prevent seizing.
4.Available in both horizontal and longitudinal configurations for the Automated Seam Welding System (H: Horizontal, L: Longitudinal).
Main Competitive Advantages
1.Conductive rotating parts adopt embedded silver bushings, with sealed oil lubrication and water cooling for the conductive base, ensuring smooth rotation and no seizing.
2.The rotating shaft in the conductive base uses nano-ceramic spraying (instead of conventional nylon), offering superior wear resistance and extended service life.
3.Square cylinder guide bars (vs. round designs) prevent welding wheel deflection, delivering higher welding quality than round guide bar models.
Machine Composition
1.Machine body: Vertical reinforced structure, welded with heavy-gauge high-quality steel plate.
2.Transformer: Stacked with 15,000 gauss permeability silicon steel sheets, internally water-cooled, full copper alloy core, low impedance, high power efficiency, 50% duty cycle for long-duration welding, high output, long service life, low noise, and compact layout.
3.Solenoid valve: Taiwan-sourced, high-speed and high-performance.
4.Cylinder: Precision machined from anti-friction hard duralumin, rust-proof, low friction, low noise, fast pressure buildup, reducing weld spatter.
5.Welding wheels: CuCrZr alloy, highly wear-resistant, water-cooled for extended service life.
6.Switches
