Seam Welding
Seam welding is a continuous resistance welding process that uses rotating wheel electrodes to create leak-tight, overlapping spot welds. This technique is essential for manufacturing tanks, containers, radiators, and any application requiring hermetically sealed joints with high production efficiency.
Seam welding passes overlapping metal sheets between two rotating copper alloy wheels (electrodes). As the wheels rotate, they apply pressure and conduct welding current to create a series of overlapping spot welds that form a continuous seam.
Seam Weld Types
Continuous Seam
Overlapping welds create a complete hermetic seal
Roll Spot Weld
Spaced spot welds for structural applications
Mash Seam
Thins the overlap for flush-surface applications

Advantages of Seam Welding
Seam welding is the go-to process for applications requiring continuous, leak-tight joints.
Leak-Tight Joints
Creates continuous, hermetically sealed welds ideal for pressure vessels and fluid containers.
High Speed
Continuous welding at speeds up to several meters per minute for efficient production.
Consistent Quality
Automated process ensures uniform weld quality along the entire seam length.
No Filler Metal
Clean process with no consumable filler materials required.
Minimal Distortion
Localized heat input reduces warping and maintains dimensional accuracy.
Versatile Materials
Suitable for steel, stainless steel, aluminum, and coated materials.
