The Electrogas vertical welder from Shenyang University Research Institute is designed for automated vertical welding of large storage tanks, operating from bottom to top. It handles plate heights between 1.40 and 3.20 meters and thicknesses from 8 to 50 mm, with single-side welding capability up to 32 mm. The system uses 100% CO2 gas shielding with flux-cored or intershield flux-cored wire, enabling deep penetration without backing plates.
The welder features an auto-lifting carriage driven by feedback from arc voltage, which adjusts wire stick-out and travel speed dynamically. Ceramic or water-cooled copper shoes are used on the front side, while a fixed backing mat - either ceramic or water-cooled copper - is applied on the reverse. This dual-cooling system controls molten pool shape and minimizes distortion. The system is built for continuous operation in industrial tank fabrication, not for field repairs or small-scale use.
This equipment is primarily used by manufacturers of oil, chemical, and LNG storage tanks with diameters of 5 meters and above. Buyers are typically engineering firms, pressure vessel fabricators, and EPC contractors requiring high-volume, consistent welds. Trade terms are FOB Dalian or CIF as agreed. The machine is shipped in a disassembled state with protective covers. Lead time is confirmed upon order and subject to component availability.

Before ordering, confirm the exact tank diameter and plate height your facility handles. Request a weld test coupon made with your preferred flux-cored wire and base material. Verify the machine’s power input matches your facility’s 3-phase supply. Do not assume the unit includes installation - this must be arranged separately with the supplier or a local technician.
Lead time is typically 10 to 16 weeks after deposit, depending on component availability. Incoterms are usually FOB Dalian, though CIF is negotiable. Payment is commonly 40% advance, 60% against bill of lading. The machine is shipped disassembled in steel frames with anti-rust coating. Request a detailed packing list, weight certificate, and export documentation before shipment.
Conduct a pre-shipment inspection for missing parts, damaged wiring, and hydraulic leaks. Request a video of the carriage moving through its full travel range under load. Confirm that the control panel is labeled in English and includes emergency stop buttons. Retain all original packaging for transport insurance. Ensure the supplier provides a manual with technical diagrams and maintenance schedules.
