Linear Welding (Welda-Long)
Linear welding systems typically have dedicated travel cars which are driven on long travel beams. They can be incorporated with positioners and other equipment to weld simple or complex weld profiles. The control schemes can range from simple motors with speed dials to computer controlled systems with servo motors and touch screen controls.
Internal and external beam welders are both common applications for construction equipment and telescoping boom sections.
Seam tracking can be provided mechanically or through integration of sensors into the control system of the machine.
