Huayan LS vertical and WS horizontal girth welders deliver consistent circumferential‑seam quality for tubes, flanges and shell components. Within the CZ custom‑built portfolio, CZ‑MA saddle welding machines handle complex intersecting seams, while CZ‑IN internal cladding systems perform corrosion‑resistant overlay inside pipe bores.
Combined with BW series positioners and double‑gun CNC pipe welding configurations, these systems support TIG hot‑wire, MIG and submerged‑arc processes. They address typical manufacturing pain‑points including difficult‑to‑reach inner surfaces and complicated saddle joints, helping offshore and pressure‑vessel manufacturers pass non‑destructive‑testing requirements and raise overall workshop throughput.
