Automatic Tank Horizontal Seam Welding Machine with LINCOLN Power Supply

The MSHW-I Series represents the next generation of horizontal tank welding machines, featuring integrated high-precision wire oscillation for superior weld bead control and quality. Designed for critical applications demanding flawless X-ray quality welds or welding of thicker materials requiring wide beads, this system offers unparalleled control over the welding arc. Its advanced control system allows fine-tuning of oscillation parameters for optimal fusion and penetration profiles.

Key Specifications:

Key Features:

• Precision Wire Oscillation: Enables wider beads, excellent sidewall fusion, uniform penetration, and smooth bead contour – essential for high-quality, defect-free welds (X-ray quality).

• Optimized for Thick Plate: Ideal for welding shell sections exceeding 25mm (1") thickness in a single pass or fewer passes.

• Superior Process Control: Digital control over all parameters (travel speed, oscillation width/freq/dwell, voltage, wire feed) ensures repeatability.

• Reduced Welding Time: Wider beads reduce the number of passes required for thick sections.

• Improved Weld Properties: Better heat distribution and fusion profile enhance mechanical properties and reduce distortion.

• Enhanced Operator Interface: Intuitive touchscreen and remote control simplify operation and monitoring from a safe distance.

• Data Logging: Records weld parameters for quality assurance and traceability.

• Robust Magnetic Adhesion: Ensures reliable operation on vertical surfaces, even with vibration.

Application Scenarios:

• Fabrication of high-integrity storage tanks for LNG, LPG, cryogenic services, or highly toxic chemicals requiring stringent weld quality standards (e.g., ASME Sect VIII Div 1/2, API 620 Appendix Q/R).

• Welding of thick-walled pressure vessels and reactors in the oil & gas and petrochemical industries.

• Construction of nuclear containment vessels or penstocks demanding ultra-high weld integrity.

• Critical infrastructure tanks where weld reliability is paramount (e.g., strategic fuel reserves).

• Applications requiring minimal post-weld grinding due to superior bead appearance.

Wincoo Engineering Co., Ltd (WINCOO) is engaged in bringing the most suitable solutions/equipments for client, fabricators, EPC/C companies on pipe fabrication, tank construction, pipeline construction, industrial production lines, clean energy project and other industrial field.

We have ability of providing workable solutions to support clients to be awarded with shorter project execution time, fewer man-hour cost and higher efficiency construction/fabrication method and better quality during phase of project bidding.

Based client’s facility/site space availability, we are able to study/design and present matched configurations on project schedule, quality, cost and productivity to guarantee production pace is accordance with project requirement.

To support project execution, we are always ready to work as fireman to give prompt supply on project materials from different consumables, tools, equipments/machines to special merchandise. With flexibility, we are also glad to perform as procurement agent in China to seek required supply resources.

Our products covers tank welding machine, tank hydraulic jacking system, pipelayer, paywelder, pipeline groove machine, pipeline bending machine and other tank/pipeline construction equipment, etc.

To familiarize clients fast to use equipment/lines/system we supplied, we can arrange engineers to implement installation, training, and commission. Meanwhile, to better support client to finish their projects, we provide operators for construction, operation or we are able to undertake such work as subcontractor.

We can provide OEM service, all the equipment/lines supplied we can produce with client’s brand.

To verify what we supply can well satisfy clients’ requirement, we sincerely would like to invite client to visit us before issuing order. We prefer to set factory acceptance test process before shipment to remove clients’ concerns.

Your support is our forward motivation.
