Cutting to the chase - Integrating secondary operations
Many tube cutoff machines have evolved to integrate end forming and bending capabilities that normally are considered secondary operations. Considering the tube industry's need to reduce costs to stay competitive, the concept of integrating more operations may sound appealing. An inline system... Read more...

Is your company a breeding ground for workplace violence?
Approximately 2 million U.S. workers are victims of workplace violence each year. In 1997 the National Institute of Occupational Safety and Health (NIOSH) reported that an average of 20 workers are murdered each week in the U.S., and an estimated 18,000 per week are victims of nonfatal...

Identifying the right cutting and welding tips
The tip of a welding or cutting torch is where the action is (see Figure 1 ). Welding tips usually produce positive pressure (higher than 1 pound per square inch ) and are used at equal pressures of acetylene and oxygen. These single-hole copper-alloy tips are attached to a torch handle... Read more...

What's that material?
An XRF system can be integrated at a detector station before final packaging. The tubes are held in place by a pneumatic clamp while the XRF detector is raised to make contact with the tube and perform the measurement. This process confirms the alloy grade of the material typically in two... Read more...

Art From the Forge
It's been happening gradually over the past 25 years, but in the past four or five years, art from the forge is finding outlets in fine art and sculpture galleries, as public art and even jewelry. These motifs, techniques, designs, and objects are heading ironwork in new directions. Much of it... Read more...

Working safely with metalworking fluids
Metalworking fluids (MWFs) are widely used in many manufacturing industries. These fluids are used in the cutting, machining, and grinding of metal parts to cool and lubricate tools and workpieces, wash away the removed metal, prolong tool life, and prevent corrosion of the workpiece....

Examining tube mill roll tooling, setup, and maintenance
Poor tooling setup and mill alignment can be costly, especially when they result in decreased production quality and scrap. Both areas must be maintained continuously. A secret to achieving maximum roll integrity is simple, but often forgotten: Roll tooling design is based on known parameters... Read more...

Monitoring laser beam performance
In the last 20 years, the use of industrial lasers for cutting, drilling, welding, marking, and cladding has increased dramatically. Industrial lasers, unlike their laboratory cousins, are not designed with continuous monitoring in mind. The laser often is assumed to be operating at peak... Read more...
