WINCOO Large Tank Butt & Corner Welding Machine: Precision Engineering for Flawless Joints

Product Introduction

WINCOO ENGINEERING CO., LTD. redefines the standards of heavy fabrication with our advanced Large Tank Butt and Corner Welding Machine. Designed to tackle the most demanding on-site conditions, this equipment is not just a welder; it is a comprehensive automated solution for achieving critical welds on large-scale storage tanks. Our portfolio features two powerhouses tailored to specific needs: the robust MLTW-P/J Submerged Arc Welding (SAW) Tractor for high-deposition butt and fillet seams on thick plates, and the ultra-portable WJ-III Swing Fillet Welder for intricate corner joints and reinforcement work .

The MLTW-P/J is a mobile tractor engineered for plates 6mm and above, utilizing the efficient SAW process to deliver deep penetration and consistent results on carbon and stainless steel . For complex corner welds, the WJ-III introduces oscillating technology, allowing for a single-pass wider bead that mimics skilled manual techniques but with robotic precision . Whether it's floor plates, wall plates, or reinforcement ribs, WINCOO provides the modular, customizable platform to ensure your tank construction is built on a foundation of integrity .

Key Advantages

1, Dual-Mode & Multi-Process Versatility: From welding bottom plates with square grooves to corner joints on box beams, our machines adapt. The MLTW-P/J handles square, single V, and double V grooves with the SAW process, while the WJ-III excels at fillet welds on reinforcement plates and rib plates, offering both stick and MIG compatibility .

2, Swing Technology for Superior Corner Welds: The WJ-III model stands out with its fully adjustable oscillating parameters. Operators can fine-tune swing speed, width, and dwell time to achieve a perfectly formed, wider weld in a single pass, significantly reducing the number of passes required compared to traditional methods .

3, Unmatched Portability & Ease of Setup: We understand that on-site conditions are tight. The WJ-III features a compact design (240×330×310 mm) with a magnetic handle for instant attachment and alignment, allowing even semi-skilled operators to perform high-quality work. The MLTW-P/J, despite its industrial power, is a mobile unit weighing only 90 kg, easily transported across the job site .

4, Intelligent Automation for Labor Savings: Equipped with user-friendly features like an induction stop switch, the WJ-III automatically halts at the end of a workpiece, enabling a single supervisor to oversee multiple units simultaneously. This drastically reduces labor costs and human error .

5, Built to Last in Harsh Environments: Constructed with a durable metal frame and corrosion-resistant materials, our machines are designed to withstand the dust, heat, and rigorous use of large-scale projects and comply with CE and ISO9001 standards .

Applications

a. Large Vertical Storage Tanks: Ideal for welding shell plates, bottom annular plates, and roof seams in the oil, gas, and petrochemical sectors .

b. Complex Steel Structures: Perfect for fabricating box beams, H-beams, and welding reinforcement plates for bridges, high-rise buildings, and industrial plants .

c. Shipbuilding and Locomotive Manufacturing: Suited for critical fillet welds on ribs, bulkheads, and cross-parts where structural integrity is non-negotiable .

d. Heavy Machinery Fabrication: Essential for constructing and repairing heavy equipment that requires reliable, high-strength corner and butt joints.
