Tube Notching Formula

Notch Depth = Branch Tube Radius × sin(Angle)
Cope Length = π × Branch Tube Diameter
Offset = Main Tube Radius × cos(Angle)

Tube notching is a fabrication process used to create accurate saddle cuts so one tube fits perfectly against another before welding.

Applications in Metal Fabrication

  • Automotive roll cages
  • Motorcycle frames
  • Pipe welding systems
  • Industrial handrails
  • Bicycle frame fabrication
  • Custom exhaust systems

Frequently Asked Questions

What is tube notching?

Tube notching is the process of cutting a curved profile into a tube so it fits tightly against another round tube.

Why is notch angle important?

The angle affects weld fitment, alignment, structural strength, and fabrication precision.

Can this be used for pipe coping?

Yes, this tool is useful for pipe coping, saddle cuts, and tube intersection layouts.
