Features

• Standard Three-Roll Weld Box Units have the first-ever “Quick Centering Mechanism” incorporated into the unit to provide fast and positive roll centering at setup and changeover removing the need for setup plugs or shimming.
• Our universal, three-jaw chuck allows each weld roll clevis to be adjusted independently or all three clevises can be adjusted simultaneously.
• Heavy Duty Weld Boxes are designed with all adjustments on the operator side for increased operator safety and reduced mill downtime. All adjustments may be made without shutting down the mill.
• Weld rolls manufactured from AISI H13 heat-resistant tool steel, precision machined, hardened, and ground.

Options

• An optional keyway can be machined into base plate of the unit to assure proper alignment, allowing easy correction of minor mill misalignment.
• The optional subbase allows lateral adjustment of the entire unit. Corrects for minor mill misalignment or wear and can be used to offset slight seam rolling.
• Optional wiper plates can be attached to each clevis, offering two additional benefits. Wiper plates provide a retainer for stainless steel wool at the rear of each weld roll as a pickup remover. Secondly, mill coolant can be directed to the back side of each weld roll via a tube fitting attached to each plate; useful when mill coolant must be restricted at the point of welding.
