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 technology has changed dramatically over the last few decades. Although skilled welders always will be needed in manufacturing, mechanical welding devices can provide improvements over manual welding in terms of repeatability and throughput.

Weld inspection, weld logging, and weld recordkeeping always have been a part of quality assurance (QA) procedures for certain industries, particularly aerospace, nuclear power, semiconductor, and pharmaceutical.

Central Washington University in Ellensburg, Wash., is known for its strong science programs. "Flying Bridge," a structure designed by artist and sculptor Ed Carpenter, physically and metaphorically spans the biology and chemistry departments in the university's new Dean Science Building. Carpenter, who designed the bridge with engineering consultation from Peterson Structural Engineers Inc., teamed up with Albina Pipe Bending Co. Inc. to tackle the project's material bending and fabrication requirements.

You can achieve nearly trouble-free bending by being aware of the causes of typical compression bending problems and by correctly operating and maintaining the compression bender. Most compression bending problems are one of three types:Flattening or collapsing on the outside of the bend.Crimping...

Early power supplies for contact and induction welding for tube production, which were introduced in the 1950s, operated at 300 to 400 kHz. Modern power supplied, introduced in the 1990s, are variable from 200 to 400 kHz. While using any frequency in this range can produce acceptable welds for most applications, finite element analysis can be helpful for finding the optimal frequency for a particular gauge and material.

For the company that broke the world record for building the tallest freestanding structure with a 320-foot scaffolding (the Statue of Liberty restoration project in 1984, see Sidebarat bottom of page)designing and constructing the scaffolding for the Washington Monument restoration project was just a natural next step.

The introduction of lasers to the manufacturing process has changed the fabrication of tubing. Today, many manual processes can be replaced with laser processing techniques. Using the flexibility afforded by lasers, a bundle of raw tubing can be loaded into a laser tube cutter; parts can be cut with high accuracy, quality, and speed; and then finished parts from the machine can be sent directly to the final assembly.

The engine roars to life, and Bruce Van Sant inches the motorcycle forward, stopping about 25 feet from the starting line. Alan Geetings, crew member of the Van Sant racing team, sprays the asphalt with water. Bruce revs up the engine. The engine's torque breaks the rear tire's grip on the asphalt and it spins furiously. The air is suddenly filled with a cloud of smoke and the smell of burning rubber. After heating the tire, Bruce approaches the starting line.

As one manufacturer of automotive exhaust assemblies recently discovered, selecting the most appropriate lubricant for a tube bending operation can have a dramatic impact on part quality, workplace cleanliness, and economic efficiency. Although the liquid lubricant it was using was reliable and...
Roll forming is a common method for producing steel tubes. It is a continuous process in which a strip is guided through several sets of rolls that form the strip into the desired shape. After the final shape is achieved, tube edges are welded together to form a closed section. After the welding operation, the tube is sized through another set of rolls to obtain the required diameter.

The hand is one of the most complex parts of your body. It enables you to execute simple or complex jobs that cannot be performed by any other part of the body. Without your hands, it would be extremely difficult to do even those routine tasks that we take for granted every day.

A wiper die is a piece of tooling used in tube bending that helps keep the bend from wrinkling. While there are many reasons and ways to use a wiper die in a tube bending maching, you should also know what types are available, their differences, and how to choose the right one for your application.

To reduce weight and cost for all types of products, design engineers often specify tubes and pipes with thinner walls instead of the previously used heavier-walled tubes and pipes. Shorter tube or pipe lengths also achieve the same objectives, but usually they require sharper or more complex bends. These designs make the tube bender's task more difficult.
