Tube and Pipe Welding Units
Tube and Pipe Welding units, or weld boxes, come in a variety of configurations, from a 3-roll “chuck style” (shown) to
a 2-, 4-, or 6-roll type (similar to a side pass stand). These units are custom designed, based on the welding application, material type, or tube size required. Liquid-cooled weld rollers are also a common element in many weld boxes.
Features:
- Heavy-duty weldment, stress relieved before machining
- Weld roll clevises are made from 300 series stainless steel for induction welding applications. This substantially reduces the energy absorption into the weld box, and puts more power to the weld zone, increasing your welding efficiency.
- Weld roll shafts are also made from stainless steel for induction welding applications and are designed to be an assembly with the weld rolls. The taper roller bearings can then be precisely preloaded in the weld roll prior to installation in the stainless steel clevises. Each clevis offers quick-change stainless steel end caps.
- Each clevis is mounted on a heavy-duty 3-jaw Rohm chuck, with operator side adjustment feature
- A face plate offers rear access holes for quick change of chuck, when needed
- Each weld roll clevis is individually adjustable for precision match-up of strip edges for welding
- Jackscrews, with anti-backlash and digital readouts for repeat setups, are provided for wrench-free vertical and horizontal adjustments
