Automated Longitudinal Seam Welding Line Spiro Stitchwelder SWA 400

Automated Longitudinal Seam Welding Line Spiro Stitchwelder SWA 400


Stitchwelder SWA 400 is an automated welding line designed for the production of couplings, bend segments, and other cylindrical or tubular components. It is widely utilized in the manufacturing of ventilation ducts and fittings. By integrating round bending (roll-forming) and stitch welding into a single module, it ensures high productivity and a significant reduction in labor costs.

Features and Advantages

Feature Advantage
High Output Productivity Produces up to 10–12 items per minute (depending on specifications), making it ideal for high-volume serial production.
Integrated Dual Process Combines roll-forming and stitch welding in one frame, simplifying production logistics and reducing material handling.
Rapid Changeover Switching between diameters or product types, including swapping the rolls and adjusting parameters, takes less than 10 minutes.
Material Flexibility Supports galvanized and stainless steel across various thicknesses with simple adjustment of welding parameters.
Compact Footprint The integrated design occupies significantly less space compared to separate forming and welding units.
Low Maintenance Costs Engineered for easy access to service nodes, which reduces downtime and simplifies routine technical maintenance.

Standard Equipment

  • Automated Forming & Welding Module: Integrated roll-forming and stitch welding station.

  • Calibration & Positioning Unit: Ensures the pipe/component is perfectly aligned for the weld.

  • Programmable Controller: Manage welding parameters for different materials (galvanized, stainless).

  • Forming Tooling: Sets of rolls and matrices for changing product diameters.

  • Integrated Feeding System: Automated handling and preparation of the workpiece for welding.

  • In-feed & Out-feed Automation: Programmable systems for initial material feeding and unloading of finished parts.

  • Safety System: Includes protective fencing and safety interlocks with easy maintenance access.

Options and Modules

  • Logistics Modules: Automatic unloading systems, conveyors, and product accumulators.

  • Extended Tooling Sets: Additional rolls and tool kits for non-standard diameters or shapes.

  • Quality Control Monitoring: Optical sensors and systems to monitor welding parameters in real-time.

  • Advanced Line Integration: Modular connectivity for marking, preparation, and packaging units.

  • High-Capacity Packages: Adaptations for larger diameters, non-standard materials, or increased sheet thicknesses.
