The VARB is a fully automated variant of the VSTW-RBi-RBa for elbow with a maximum diameter of 200 mm (8").
The VARB automated stitchwelder
Depending on the requirement, the pre-fabricated half shells can be placed into the tools manually or automatically by a robot. The weld operation is fully automatic and has consistent quality.
The VARB is best suited for applications with a high degree of automation and large production runs that need to be handled in a cost-efficient manner. The VARB requires a separate clamping and holding tool for each pipe bend diameter. No more than 10 minutes are normally needed for retooling, including time for changing of material and adjustment of parameters.
