- Resistance Seam Welder, Longitudinal Welding
The rotating shaft on the circular electrode is perpendicular to the electrode arm, with the formed welding seam parallel to the electrode arm. Longitudinal welding is used not only for welding straight seams, but also circumferential seam welding in order to save customer purchasing costs for additional equipment.
- Seam Welder, Resistance Welding System
Seam welders are used for long straight seam welding and circumferential seam welding. The rotating shaft for the circular electrode is perpendicular to the electrode arm, so that the welding seam formed is parallel to the electrode arm.
- Universal Seam Welding, Resistance Welder
Universal seam welding performs transverse welding and longitudinal welding at the same time. It is a resistance welder that places the workpiece between the circular electrodes using either continuous or intermittent rolling and a current to form a welding seam.
Seam welding uses a pair of roller electrodes instead of a cylinder electrode and spot welding. The welded workpiece moves between the rolling plates, thus generating a series of sealing welds that overlap with each other to weld the workpiece together. Seam welding using our equipment meets all the welding needs for tanks, buckets and other vessels with different specifications.
- DC welding saves up to 30% more power than traditional AC welding.
- High welding intensity, no leak and excellent sealing performance after welding
- Longer service life with silicon controlled cooling transformer.
- Can be used for circular seam welding and longitudinal welding, thus saving money without having to purchase other, related equipment.
