Key Features:
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.
Application Scenarios:
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.
