Seam Weld Wheels
Sourcing your seam weld wheel.
When sourcing your seam weld wheel it is important to remember that you should NOT use a cast weld wheel. A forged wheel is required for a robust wheel and a repeatable, reliable weld.
Choosing your weld wheel material.
Seam weld wheels can be made from RWMA class 1 copper , RWMA class 2 copper , & RWMA class 3 copper .
For welding steel alloys, the most common and cost effective material is RWMA class 2 copper.
RWMA class 3 wheels should be used when welding stainless steel.

Why upset-forged seam welding wheels perform better & last longer...
Individually upset-forged seam welding wheels increase production up-time and enhance weld performance because of their fine equiaxed grain microstructure.
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 contribute to edge chipping and flaking, unreliable performance and higher production costs.
How to tell them apart....
Forged and cast wheels look alike and have similar hardness and electrical conductivity properties. On the surface it's hard to tell them apart. But, when the surfaces of both wheels are chemically etched, the difference in the grain structure is revealed.
Take note, there is a direct relationship between your production up-time and the method of manufacturing used to produce the seam weld wheel you choose to use. Individually upset-forged welding wheels outperform cast wheels every time, making them the clear choice for extending electrode life. Many RWMA suppliers do not understand the importance of, and do not supply, individually forged wheels. Production Engineering only sells individually upset-forged and heat-treated seam welding wheels. Most products are available from inventory, or can be custom made to meet your specific needs.
