PLC Control Modular Orbital Welding Machine for Large Size Pipeline Construction

Product Introduction

The WINCOO WQ-III is a modular, rail-based orbital welder for high-volume fabrication of long-distance pipelines. Its Automation PLC synchronizes a rotating welding head with adaptive fill-pass algorithms, enabling unmanned 6G welding of fixed pipes in factory settings.

Key Parameters

Core Features

1. 1. Adaptive Welding Intelligence

   • Auto-senses joint geometry (V-bevel, J-prep) and adjusts heat input per pass.

   • Closed-loop current control via PLC-integrated arc voltage feedback.

2. 2. Multi-Pass Optimization

   • Automated crater filling and interpass temperature management.

   • Post-weld data reports (voltage, current, travel speed) for NDT compliance.

3. 3. Ergonomic Modularity

   • Split-rail design for quick installation on fixed pipes.

   • Remote pendant control (50m range) with live weld visualization.

4. 4. Certification Ready

   • Pre-qualified for ASME Section IX • Embedded PQR/WQR documentation.

   • Password-protected weld procedure locks for audit trails.

Applications

• Pipeline Fabrication Yards: High-speed welding of pipe spools for compressor stations.

• Process Piping: ASTM A335 P11/P91 alloy welding in power plants.

• Municipal Water Transmission: Corrosion-resistant cladding of ductile iron pipes.

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.
