Advanced EGW Vertical Seam Welding Machine for Thick-Wall Tanks

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.

• 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

• 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
