Product Introduction:
The EGW Series revolutionizes vertical welding for ultra-thick storage tanks
(e.g., LNG, LPG, cryogenic vessels). Featuring dual-wire tandem EGW
technology, it achieves deposition rates exceeding 25 kg/h (55
lbs/h), welding plates up to 100mm thick in a single pass.
Integrated oscillation and real-time seam tracking ensure flawless
fusion in critical applications requiring ASME Section VIII or API
620 compliance. Ideal for shipyards and heavy fabrication shops.

| Power Supply | 480V AC, 3-Phase, 200 kVA |
Key Features:
Industry-Leading Speed: 2x productivity vs. standard EGW for thick sections.
Deep Penetration: Dual-arc synergy ensures full fusion on 100mm plates.
Active Arc Control: Independent parameter adjustment for each wire.
Zero-Defect Guarantee: Auto-correction via seam tracking & oscillation.
Remote Monitoring: Real-time weld analytics via IoT interface.
Cryogenic-Ready: Optimized for 9% Ni steel, stainless steels, and aluminum alloys.
Application Scenarios:
LNG/LPG storage tanks (API 620, Appendix Q).
Cryogenic vessels (-196°C service).
Thick-wall reactor shells in petrochemical plants.
Nuclear waste containment tanks.
Offshore platform leg sections & gravity-based structures.
