In wheel welding, the electrical current is transmitted through a contact wheel at the weld point. The contact wheel applies some of the forge pressure necessary for the welding process. The three main types of wheel welders are AC, DC, and square wave. In all three power supplies, electrical current is transferred by brush assemblies that engage slip rings attached to a rotating shaft that supports the contact wheels. These wheels transfer the current to the strip edges.
Wheelabrator Blasting equipment is a centrifugal blast cleaning machinery that throws steel abrasive material, cleaning items at a fraction of the cost of conventional cleaning methods. The direct drive blast wheels offer consistent production and superior performance. The steel abrasive is cleaned and recycled, reducing disposal and minimizing abrasive costs.
