Corner Welding Machine Schnelldorfer CORNER ONE 320

Corner Welding Machine Schnelldorfer CORNER ONE 320


CORNER ONE 320 is a specialized high-speed automatic machine for corner welding, designed to join simple profiles and rear-lipped profiles at a angle. As part of the Generation ONE series, it delivers impressive speed and precision, completely eliminating the need for post-weld processing (grinding and polishing).

The model 320 provides a maximum welding length of up to 320 mm on workpieces with a diagonal ranging from 70 mm to 1000 mm. It is the ideal solution for producing electrical enclosures, control cabinets, industrial kitchenware, and HVAC components. The primary welding process is TIG (GTAW).

Features and Advantages

Feature Description
Zero Post-Processing Produces high-quality, discoloration-free welds, resulting in up to 89% time savings compared to manual welding and subsequent grinding.
Precision for Thin Sheets Optimized for fast and accurate corner joints on thin-gauge metals ranging from 0.5 mm to 2.5 mm.
Efficient Clamping Pneumatic clamping system with a pre-clamp feature ensures fast, safe, and high-precision workpiece positioning.
Profile Flexibility Capable of welding corners with an inward return flange up to 38 mm and an outward return flange up to 10 mm.
Reliable Components Powered by a Siemens S7-1200 controller and a Schneider Electric LEXIUM stepper motor for consistent torch travel.
Material Versatility Suitable for welding stainless steel, mild steel, galvanized steel, and aluminum.

Standard Equipment

  • Control System: Siemens S7-1200 PLC and a Siemens Panel KP 400 (4” color display).

  • Drive System: Schneider Electric LEXIUM stepper motor for controlled and repeatable torch movement.

  • Clamping: Pneumatic clamping system with a pre-clamp function.

  • Internal Tooling: Internal clamping tool made of wear-resistant copper alloy (CuCrZr).

  • Gas Management: Three-level gas supply: Torch gas, Backing Gas (internal), and Trailing Gas (external) for full seam protection.

  • Welding Interface: Standard 2/4-stroke interface for connecting various power sources.

  • Cooling: Integrated cooling circuit for the internal tooling and the torch.

Options

  • Welding Modules: Torch Oscillation Unit and various specialized welding power sources.

  • Extended Tooling: Sets of extended height clamping fingers for complex flanges and specialized backing segment sets.

  • Automation: Barcode scanner for workflow organization and a router for remote diagnostics.

  • Specialized Nozzles: Options like 5-zone or double 3-zone nozzles for enhanced gas shielding.
