NOTCHING OPTIONS--Six processes for notching tube, pipe

摘要

FABRICATORS use notching for applications as varied as bicycle frames, automobile components, aerospace parts, and household piping systems. Notching takes many forms and shapes. The equipment and process needed depend on the notch shape, the raw material, and manufacturing considerations such as tolerance and production rate. Tube notching is most often performed before joining tubes together to make a T or similar joint. Either one or both tubes may be notched before being welded together. End notching is the process of forming a cut on the end of a tube to create a shape that will mate to an existing tube. Side notching (offset notching) is the process of cutting an opening into the side of a tube to create a V notch for bending or a V notch for a T joint.
