Rolling Smooth, Wearing Slow:
SVS Standards for Welding Wheels
Seam welding electrodes are made from heat-resistant, high-conductivity copper alloys and ensure reliable performance in high-cycle operation. Precision-machined surfaces support consistent current transfer and controlled thermal behavior. Critical wear zones are hardened and optionally coated to increase service life and minimize spatter buildup.
Available in standard designs or as custom versions based on drawings or samples. Geometry, interface and material are precisely matched to your specifications.

Fundamentals
Functions of Welding Wheels in Seam Welding
During resistance seam welding, the upper and lower wheels press two overlapping sheets together and guide current precisely through the joint. At the contact points, electrical resistance generates heat that locally melts the material.
With each pulse, a single weld nugget is formed. As the electrodes roll forward, the nuggets are placed tightly in sequence or slightly overlapping. When solidified, they merge into one continuous and sealed weld seam.
Key Parameters of Seam Welding Wheels
A well-matched alloy ensures efficient conductivity and thermal control. This balance is key to managing heat input and preventing local overheating during welding.
High contact forces and rolling motion place mechanical stress on the electrode. A hardened or coated surface reduces wear, prevents buildup and keeps current transfer stable.
Precision manufacturing is essential to ensure even current and force distribution. Inaccuracies can cause seam deviation and reduce weld consistency.
Upper and lower electrodes only perform reliably as a coordinated unit. Consistent seam quality depends on a precise match of material, hardness and geometry.
