Resistance Seam Welding Wheels FOR SALE
Buy Seam Welding Wheels from our IN-STOCK inventory
Seam welding is very similar to spot welding. However, two opposing wheels are used, rather than two pointed electrodes. Force and current is applied through the wheel. Control timing and wheel speed determine the spacing of the welds. Seam welding wheels can overlap, be fluid tight or separated. A separated seam welding wheel setup is often called a roll spot weld.
Resistance seam welding wheels can be made from RWMA class 1, class 2, class 3, class 11 and class 13 in a variety of diameters and thicknesses. For welding steel alloys, the most common and cost effective material is RWMA class 2. RWMA class 3 wheels should be used when welding stainless steel.
Available to be shipped within 24 hours. When you buy from Weld Systems Integrators, you’re guaranteed high quality equipment along with trained / professional support services.

RWMA classes are standards used in the resistance welding industry to classify the composition and properties of materials used in welding operations. These standards ensure that when you specify an alloy class, you know what to expect in terms of performance characteristics. This standardization is crucial for quality control and process reliability across different manufacturing setups.
- Class 1 for general-purpose welding.
- Class 2 for higher heat applications.
- Class 3 for strength and durability.
- Class 11 or 13 are used for their resistance to electrode sticking and exceptional wear properties.
Upset-forged seam welding wheels vs. cast wheels:
Individually upset-forged seam welding wheels have a fine equiaxed grain microstructure which performs better, lasts longer, increases up-time and enhances weld performance. This fine radial grain flow, the essential property for minimizing premature edge deformation, can only be produced by the upset forging process. Each wheel must be individually forged and heat treated to develop this advantageous microstructure.
Cast wheels, produced without forging, have large columnar grain structures that can chip and flake, and produce unreliable results and higher production costs.
Forged and cast wheels look alike and have similar hardness and electrical conductivity properties. The difference in the grain structure can be revealed when surfaces of both wheels are chemically etched.
Weld Systems Integrators can help you identify the seam welding wheels that best fit your application. Call WSI and provide the desired material specification (Class 1, 2, 3, 11, 13), wheel diameter and wheel thickness.
