WINCOO Standard Electrogas Welding (EGW) System for API Tanks

The WINCOO Standard Series is a purpose-built vertical welding system for fabricating the longitudinal seams of large aboveground storage tanks (ASTs). Utilizing the Electrogas Welding process, it creates high-integrity, single-pass welds in thick plate (typically 9-40mm) with exceptional deposition rates. The system operates vertically upwards using sliding copper shoes to contain the molten weld pool and shielding gas, ensuring X-ray quality joints for critical storage applications like oil, chemicals, and water tanks compliant with API 650/653 standards.

• High Deposition Efficiency: Single-pass welding eliminates multi-layer processes, reducing labor by 70%.
• Exceptional Quality: Copper shoes ensure smooth weld profile & minimal spatter; ideal for X-ray/UT inspection.
• Automated Operation: PLC-controlled travel speed, voltage, and wire feed for consistency.
• Rigid Guidance System: Precision rails ensure vertical alignment over full seam length.
• Quick-Setup Shoes: Interchangeable copper shoes adapt to plate thickness changes.
• Gas Containment: Integrated gas chambers maintain optimal shielding atmosphere.

• Longitudinal seams in crude oil/fuel storage tanks (API 650).
• Water reservoir tanks (>10,000 m³ capacity).
• Chemical storage tanks (acid, alkali, ethanol).
• Tank refurbishment (API 653 repairs).
• Power plant surge tanks & penstocks.
