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.

Large-radius bends are used in many places, such as appliance handles and automobile components. For measuring large-radius bends, fabricators have at least three options: go/no-go fixtures, entering the bent part’s measurements into a CAD program and using it to calculate the radius, and a depth gauge.

In conventional metalforming operations, the main way to reduce friction between the tooling and the workpiece is to apply a lubricant. Another supplementary method, which has been used for decades, is to introduce ultrasonic energy to the tooling, resulting in microscopic, high-frequency vibrations that reduce friction and improve surface finish.

Mobile phone systems are mainly electronic, but a fabricated tube plays a critical role—known as a waveguide, this rectangular tube connects the transmitter to the antenna. Precise bending and forming are critical to manufacturing a waveguide that provides a strong, clear signal.

It wasn't that long ago that Joe Fabiani decided to make a custom exhaust system for his Porsche. A member of the Porsche Club of America (PCA) and racing enthusiast, he soon found himself making exhaust systems for fellow PCA members. That led to founding a company, FabSpeed Motorsports Inc., which initially relied on outsourcing for nearly all of the fabricating. Fabiani recently opened a new division, FabSpeed Precision Services, and invested nearly $1 million in equipment in the new division to eliminate outsourcing.

There are a few popular ways to affix the clamp die and pressure die to a rotary draw bending machine. All aim to accomplish the same thing: provide precise vertical alignment to the mating bend die and provide rigid support for the respective die during the bending process so it resists the...

Ace Metal Crafts installs a laser tube cutting system with integrated tapping, a system that has shown its strength when producing structural tube. The machine cuts tube shapes, laser cuts holes, and performs tapping all in one setup.

A collet closer, commonly found on CNC or NC tube benders, serves an important role in the bending process. When quality is good, little attention is paid to its operation. When one or more quality parameters fall outside of acceptable limits, often the collet closer again is overlooked. A...

When James Castoro founded Custom Aluminum Products in 1960, the company’s premise was simple and concise: It produced aluminum products, mainly storm windows and storm doors. It was a good time to be in the business—the baby boom was in full swing, and the U.S. population was...

Selecting the right tungsten electrode, and preparing it to match the welding process, aren't just good ideas to maximize welder productivity. They are necessary to prevent weld defects and all the time necessary for troubleshooting and rework.

Lasers have been in use for industrial purposes for decades, and their capabilities continue to develop. Many machines these days can cut sheet and tubular sections, and fabricators are finding that the laser’s programmability really broadens their capabilities.
