Backgouging

Whether longitudinal or circumferential weld, our grinding solution is based on grinding wheel technology and prevents hardening and carbonisation of the corner zone.

High quality grinding and polishing of surfaces on dished ends, vessels, cones etc, inside and outside, in sizes between 230mm and 14000mm, according to customer requirements. Leading manufacturers around the world use our grinding solutions.
