High-end longitudinal roller welding machines: the innovation of CEMSA International

CEMSA International srl, a global leader in designing and manufacturing special resistance welding machines, has recently developed a new series of high-end longitudinal roller welding machines.

Using copper wire technology, these new welders are suitable for processing galvanized and aluminum steel (up to 1.3 mm thickness) and allow for a ''constant trace'' welding that preserves the integrity of the rollers. The superficial zinc deposits on the copper wire, moving in unison with the rollers; once impregnated, it is automatically shredded and collected for subsequent recovery of the copper base (circular economy).

The new series of welders are equipped with dual synchronized motors (brushless motors) that facilitate a push-pull-type process applied to the upper roller (pull) and the rear clamp carriage (push). That guarantees a smooth and precise linear flow of the product to weld. Additionally, a containment system integrated with the machine body keeps the product within adjustable linear roller guides, depending on the size of the workpiece.

Some technical data:

• Diameter: 100 mm ÷ 900 mm 
• Maximum lengths: 1000 mm ÷ 1850 mm 
• Linear speeds: 2m/min ÷ 12m/min 
• Thicknesses: 0.4 mm ÷ 1.3 mm 
• Copper wire Cu 99.9% slightly annealed, 2.5 mm

These welders are particularly suitable for the ventilation, plumbing, and heating sectors, representing a broad field of application for CEMSA’s machines and equipment. To find out which solution is most appropriate for your welding needs, contact the company staff through the info on the side.
