Longitudinal Seam Welding Machine Schnelldorfer LINEARWELD XLS EXTL 3600

Longitudinal Seam Welding Machine Schnelldorfer LINEARWELD XLS EXTL 3600


LINEARWELD XLS EXTL 3600 is a powerful and robust machine designed for the automatic longitudinal welding of external metal seams (EXTL). This model is part of the XLS series (eXtra Large and Strong), engineered for the highest industrial loads and capable of working with material thicknesses up to 15 mm. With a welding length of 3620 mm, its standout feature is the electrically height-adjustable clamping bed, providing maximum flexibility for positioning large and heavy workpieces. Powered by SIEMENS controls and the intelligent HMI “neXt” interface, it is fully Industry 4.0 ready.

Features and Advantages

Feature Description
Reinforced Design The XLS series is built for extreme durability, handling materials from 0.5 mm up to 15 mm thick.
Maximum Diameter Flexibility The electric height adjustment allows the machine to accommodate workpieces with massive external diameters (up to 5190 mm depending on configuration).
Premium SIEMENS Components High-quality PLC controllers and servo drives ensure ultra-precise torch movement and long-term reliability.
Industry 4.0 Ready The neXt Control system supports OPC UA, Sm@rt Server, Remote Access, and OEE monitoring for optimized production management.
Superior Weld Quality Delivers high process repeatability and clean welds without discoloration (heat tint) or significant part deformation.
Process Modularity Supports the integration of all major welding processes, including TIG, Plasma, MIG/MAG, and Plasma Keyhole.

Standard Equipment

  • Control System: SIEMENS PLC and servo drives. Features the HMI "neXt" interface with integrated video setup assistance.

  • Structural Frame: Stable heavy-duty frame with an electrical system for adjusting the height of the clamping bed.

  • Clamping System: Pneumatic clamping with a pre-clamp feature and fingers made of wear-resistant CuCrZr copper alloy.

  • Mandrel & Cooling: Specialized mandrel with a quick-change backing bar system and integrated cooling for both the torch and the mandrel.

  • Gas Management: Dual-supply system for Backing Gas (internal) and Torch Gas (external) for comprehensive seam protection.

  • Safety: Fully compliant with CE-Mark standards.

Options

  • Welding Enhancements: Cold Wire Feeder, AVC (Automatic Voltage Control), Torch Oscillation Unit, and Plasma-Keyhole or Laser modules.

  • Logistics & Ergonomics: Roller tracks, Insertion Trolleys for easy loading, and a mobile HMI operator station.

  • Advanced Control: Barcode scanner for program recall, Remote Access router, and OEE Dashboard monitoring.

  • Specialized Tooling: Various backing bar types (SOFT, STRONG, HEAVY DUTY) and heightening elements for larger diameters.

  • Data Monitoring: High-end systems like HKS for recording and monitoring critical welding data.
