GREDGER - Back Gouging Grinder
Back gouging is the process of removing excess weld material from the back side of a weld joint. Properly executed back gouging ensures complete weld fusion at the root side of the weld.
The GREDGER Back Gouging Grinder delivers precise back gouging, cleaning the weld area without the hazardous toxic fumes often generated by other methods. At the same time, it significantly reduces the physical strain on operators compared to manual grinding, while greatly increasing productivity.
Intelligent Floating System for Consistent Depth and Accuracy
The GREDGER grinder is equipped with an advanced Intelligent Floating System, electronically controlled to guarantee a consistent gouging depth along the entire weld. This smart system adapts to vessel ovality, maintaining gouging accuracy and ensuring uniform results. In addition, the automatic lateral movement keeps the gouging groove perfectly aligned and the weld seam precisely tracked. This high level of automation not only boosts productivity but also enhances the quality and consistency of weld preparation.
