# Classification
Available in diverse configurations, this equipment is categorized as follows:
By power source: AC and inverter DC
By welding wheel orientation: Horizontal and longitudinal
By quality grade: Premium grade and basic type
All variants belong to the professional Seam Welding Machine series.
# Features
1. Fitted with a 3-phase variable-frequency motor, delivering uniform welding speed, straightforward adjustment, and consistent operational stability.
2. The welding circuit loop utilizes internal water cooling, whereas the welding wheels (electrodes) are cooled via external water circulation.
3. The conductive rotating components adopt an embedded silver bushing structure; the conductive base is sealed oil-lubricated and water-cooled to maintain flexible rotation and prevent seizing.
4. Designed for versatile production, this
Automated Seam Welding System supports both horizontal (H) and longitudinal (L) welding setups.
# Core Competitive Advantages
1. The specially designed embedded silver bushings for conductive rotating parts, paired with sealed oil lubrication and water cooling on the conductive base, ensure smooth rotation without jamming.
2. The rotating shaft within the conductive base features nanometer ceramic spraying, offering superior wear resistance over conventional nylon materials and significantly prolonging service life.
3. Square cylinder guide bars replace the common round type, effectively preventing welding wheel deflection and delivering more reliable welding quality.
# Machine Construction
1. Machine body: Built with a vertical reinforced framework, welded using high-grade thick steel plates.
2. Transformer: Fabricated from 15000 gauss high-permeability silicon steel sheets, with internal water cooling and a full copper alloy core. It features low impedance, high power efficiency, 50% duty cycle for continuous welding, high output, extended service life, low noise, and a compact layout.
3. Solenoid: Sourced from Taiwan, with high response speed and stable performance.
4. Cylinder: Made of high-precision wear-resistant hard duralumin, rust-free, low-friction, low-noise, and fast in pressure application, effectively reducing welding spatter.
5. Welding wheels: Manufactured from CuCrZr alloy with exceptional wear resistance, and water-cooled for longer service life.
