Shear and welder machine FAQ

What is a shear and welder machine used for?

A shear and welder machine is used to shear the ends of two metal coils and weld them together, allowing for continuous operation in a coil processing line without stopping production.

Can it be integrated with an existing coil line?

Yes. Shear and welder machines are often modular and can be integrated into existing press lines, cut-to-length lines, or galvanizing lines with proper control system alignment.

What is the typical welding speed?

Welding speed ranges from 800 to 1200 mm/min, depending on material type, thickness, and welding method.

How accurate is the weld alignment?

The machine ensures weld alignment accuracy within ±0.2 mm, helping maintain downstream processing precision.

Can it handle high-speed production lines?

Yes. High-end models are designed to operate with production speeds of up to 120 meters/minute, depending on the line configuration.
