Top Cover Joining

Cover Welding

Secure, seamless and fully automated top cover joining techniques for long-term operational durability.

Transformer tank top cover welding
System Overview

What the system does

Cover joining is the step where the tank is closed and tightness is finally determined. A continuous, even circumferential seam is decisive for both oil tightness and visual quality.

Automated cover welding completes the circumferential seam in a single pass at constant speed, with start-stop overlap managed by program. When the cover type or tank size changes, production switches over through the program set.

Highlights
