Longitudinal Seam Welding Machine Schnelldorfer LINEARWELD XP 800

Longitudinal Seam Welding Machine Schnelldorfer LINEARWELD XP 800


LINEARWELD XP 800 is a high-precision automatic longitudinal welding machine within the XP series. It is specifically engineered to provide maximum accuracy when working with minimal tube diameters (from 40 mm) and thin-walled materials (up to 0.8 mm). Utilizing premium components from leading manufacturers—including a SIEMENS-based control system and the intelligent HMI “neXt” interface—the XP model is perfectly suited for high-tech sectors like the aerospace and medical industries, where miniature dimensions and flawless seam quality are critical.

Features and Advantages

Feature Description
Small Diameter Specialization Enables high-precision welding of cylindrical parts with internal diameters starting as small as 40 mm.
Premium Components Built with high-quality SIEMENS PLC controllers and servo drives, ensuring reliability and precision in all movements and processes.
Industry 4.0 Ready The neXt Control system features OPC UA connectivity, AI-driven parameter control, and intuitive process visualization.
Deformation-Free Welding A precise pneumatic clamping system and optimized process control minimize part distortion and ensure welds without heat tint (discoloration).
High Reproducibility Delivers consistent quality and high process repeatability, which is essential for serial production in regulated industries.
Modular Design Supports the integration of all common precision welding processes: TIG, Plasma, and Microplasma.

Standard Equipment

  • Control System: SIEMENS PLC and servo drives for dynamic and precise torch movement control. Includes the HMI "neXt" user interface.

  • Clamping: Pneumatic clamping system with a pre-clamp feature to securely fix delicate, thin-walled parts before the final weld.

  • Mandrel & Cooling: Specifically adapted mandrel design with a quick-change backing bar and integrated cooling.

  • Gas Management: Delivery systems for Backing Gas (through the mandrel) and Torch Gas for optimal weld pool shielding.

  • Safety & Standards: Fully compliant with CE-Mark standards.

Options

  • Welding Modules: Cold Wire Feeder, AVC (Automatic Voltage Control), and Torch Oscillation Unit.

  • Specialized Mandrels: Solid round mandrels or units with custom geometries to achieve even smaller internal diameters.

  • Automation & Software: Barcode scanner for program recall, Remote Access for long-distance diagnostics, and Advanced Data Store for welding data management.

  • Monitoring: High-resolution systems for recording and monitoring real-time welding data.
