The automatic half-shell welding machine for larger elbows

The VARB XL is the large version of the VARB and is suited for particularly large elbows with a diameter of up to 315 mm (12”). In the VARB XL work pieces are clamped and welded in a horizontal position. The system concept is designed for fully automated operation. The VARB XL requires a separate clamping and holding tool for each pipe bend diameter. No more than 10 minutes are necessary for retooling, including change of material and adjustment of parameters.

Benefits at a glance

  • Production of very large elbows with thin material radius
  • High quality because the weld process is guided with shells
  • Integration in a fully automated production line easily possible
  • Only 10 min. for a product change
