High-Frequency Mill Component

Our high-frequency weld boxes have been the industry standard for over 50 years. Tough, dependable, and designed with simplicity in mind, tube and pipe manufactures have turned to Addison Machine for the best in weld boxes. Built-in "Quick Centering Mechanism" eliminates set-up plugs and positive roll locating eliminates shimming.

Light-wall tube producers typically prefer our Chuck Rotation Mechanism. Simply by loosening the three mounting bolts on the chuck face, the entire assembly can be rotated to allow use of a single grooved roll on top to straddle the welded seam.


Primary functions are to stabilize and guide the strip edges as they enter the weld apex, and to apply pressure to forge the heated edges of the formed strip together for a good weld. As such, the unit's weld rolls must be capable of providing enough pressure to upset the edges sufficiently to ensure impurities are squeezed out.
