The tube and pipe fabrication technology area covers sawing (band, circular, and friction) and other cutting processes, such as abrasive, flame, laser, oxyfuel, plasma, and waterjet. It also discusses forming processes, including bending and end forming. Finally, it includes a handful of miscellaneous processes, such as trimming, beveling, finning, grooving, threading, and spinning.

Welding applications in the aerospace industries demand high precision, a quality that can be entirely as low as possible. Automatic orbital welding is being used to help meet these requirements.

The rotary cutting process rotates a tube or pipe and cuts it with a rotating blade. The blades are beveled to various angles and produce a chamfered end on the workpiece. Selecting the right bevel angle is the key in getting an optimal combination of end finish and production rate. Proper alignment and clearance, the use of a lubricant, frequent inspections, and proper sharpening are the keys to long blade life.

The rotary cutting process rotates a tube or pipe and cuts it with a rotating blade. Because it is a chipless cutting method, it does not waste any material and reduces or eliminates subsequent deburring and cleaning operations. Although it can be used on any metal, it is not suitable for every application. The cutting action produces a slight chamfer on the end of the workpiece, so it is not useful for applications that require a square end. Machine types include manual and pneumatic. Accessories include cutter block assemblies that support the workpiece during the cut; length gauges for repeatable cut lengths; and feed systems that store and feed the material into the cutting machine.
