PLC Control Heavy-Duty Pipeline Orbital Welding Crawler Machine

Product Introduction

The WINCOO orbital welding machine is an autonomous, PLC-driven welding crawler engineered for high-precision circumferential welding of large-diameter pipelines (≥12") in field construction and cross-country projects. Its intelligent Siemens PLC integrates motion control, welding parameter management, and real-time seam tracking to execute flawless all-position welds (1G–6G) without pipe rotation.

Key Parameters

Core Features

1. Smart PLC Architecture

   • Unified control of travel speed, oscillation width, voltage, and wire feed.

   • Stores 200+ welding procedures (WPS) with automatic parameter interpolation.

2. All-Position Stability

   • Electromagnetic adhesion (1,500 N holding force) for vertical/overhead welding.

   • Gyro-stabilized torch head compensates for gravitational drift.

3. Advanced Sensing Suite

   • Laser vision joint tracking + through-arc monitoring for root-pass consistency.

   • Real-time defect detection (undercut, porosity) with audio-visual alerts.

4. Ruggedized Design

   • IP65-rated enclosure (dust/water-resistant) • Operates in -20°C to 50°C.

   • Quick-change track modules for pipe diameter transitions.
