WINCOO Large Tank Girth Welding Machine – High‑Performance Automatic Solution for Heavy‑Duty Tank Construction

1. Product Overview

WINCOO Large Tank Girth Welding Machine is a self‑propelled automatic welding system designed for horizontal girth seams of large tanks. It adopts submerged arc welding (SAW) as the standard process and supports single‑sided or double‑sided synchronous welding. The machine is widely used in on‑site tank erection and factory tank production, helping users achieve X‑ray qualified welds with high efficiency and consistency.
