Coping Pipe for Strong Welds

Written by: Greg Dawes, Application Engineer

When welding two pipes together at an angle just trimming one to the other doesn’t give us a desirable result.

Welding pipes together

In order to have a strong weld between the two pipes, we need to have a pipe wall that is a constant thickness.

The Steps to get a constant wall thickness:

  1. Create a ruled surface from the inside edge that is Normal to the Surface or Perpendicular to a Vector (Pipe extrude direction)

  2. Extend the surface toward the inside of the pipe.

  3. Use “Cut with Surface” with the surface body made in the previous two steps

  4. Delete the surface body.

And Voila!
