1. Product Description

This Portable Welding Seam Grinding Trolley is designed for circular seam grinding and polishing on cylindrical metal tanks such as stainless steel storage tanks, pressure vessels, and similar components. It can also be used for pre-weld V-groove slag removal and oxide cleaning.

The unit adopts a compact wheeled chassis, allowing easy maneuverability on-site. It integrates a belt grinding system and cutting disc module, with automated lateral tracking, ensuring efficient and consistent grinding along circumferential weld seams. The system includes a dust suction pipeline, spark filter box, and silent air pump, working in conjunction with an industrial-grade dust collector for a clean and safe working environment.
