Full-Automatic Flexible Internal Pipeline Welder for Mountain Terrain: Articulated Architecture, Adaptive Centring and Sector-Based Root Welding
Mountain slopes break the rigid internal welder: ovality beyond 1.5%, hi-lo up to 6 mm, bends under 1000D. This engineering guide covers the articulated chassis, per-arm servo centring, laser groove-scan compensation, 12-sector weld schedules, field troubleshooting, a gorge-section case study and a FAT checklist.
