Product Overview
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.
