DFM Review & Engineering Support
Every tube notching project begins with engineering analysis. We evaluate your joint geometry for optimal notch profiles, fit-up tolerances, and weld access.
- Tube diameter, wall thickness, and material specification
- Joint angle and notch type (saddle, cope, miter)
- Fit-up tolerance requirements for welding
- Number of notches per tube and spacing
- Quantity and delivery timeline
Workflow: Upload design → 48h feedback → Quote with DFM notes → Prototype or production run
