Mod-Weld Dual Station Headstock/ Tailstock
The MOD-WELD® Dual Station Headstock/Tailstock system from APT Manufacturing Solutions is designed for long and large components that require controlled rotation during welding. This configuration allows the workpiece to be positioned for improved weld access, consistency, and efficiency.
For education and workforce training programs, this system helps students understand how robotic welding extends beyond basic table-based applications. Learners can explore coordinated motion, part orientation, torch access, fixture planning, and the role of rotation in complex weld paths.
The Headstock/Tailstock system is a strong fit for advanced welding, fabrication, and automation programs preparing students for industrial robotic welding applications.
- Best for long or large parts that need controlled rotation during welding.
- Improves weld access by positioning the part instead of forcing difficult torch angles.
- Supports advanced robotic motion training through coordinated robot and part movement.
- Ideal for complex geometries, cylindrical parts, and longer assemblies.
With rotating parts and complex geometries, the Headstock/Tailstock configuration benefits from welding processes that maintain arc stability across changing orientations.
- Fronius TPS/i: Supports precision welding across varying angles and complex part geometries.
- Miller Auto-Continuum™: Maintains consistent arc behavior during repeatable robotic weld cycles.
- Fronius LSC: Helps reduce spatter and improve weld seam quality.
- Fronius CMT: Supports thin material, brazing, cladding, and multi-material applications.
- FANUC TPW: Helps the robotic system adjust to part variation through touch sensing and seam tracking.
- Tip reamer, nozzle spray, and wire snip system
- Additional Allen-Bradley I/O
- Laser seam finding and tracking
- FANUC iRVision for 2D and 3D part location
- Additional closed-center valve options
