Choices in flying cutoff saw blades
Tube and pipe producers are a demanding breed. They have to be. With line costs up to $15,000 per hour, unexpected downtime can destroy the bottom line. Keeping the line up and running is critical, and in tube and pipe production shops everywhere, one important concern is the cutoff area.... Read more...

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...

Incorporating beveling economically
It's first important to know why and how beveling is used, and the key is realizing that joint design is process-dependent. In other words, you can't use a certain joint configuration from a book for just any process. Changing your welding process will affect the impact beveling has on... Read more...

Boosting band saw blade life
Fabrication, welding, and machine shops frequently use band saw blades to make just a few cuts in a variety of materials. Cuts are made as the need arises rather than based on a predetermined high-volume cutting schedule. Because this type of intermittent cutting can be hard on blades,... Read more...

MIAB welding of thick-walled pipe ends
Various methods are used for welding pipe, including electric shielded metal arc welding (SMAW), submerged arc welding (SAW), and flash end welding. Another efficient process is magnetically impelled arc butt (MIAB) welding. Current technology and equipment allow MIAB welding of pipes with wall... Read more...

Notching tube and pipe
The Hole Saw Using a hole saw is an inexpensive way to make the occasional notch for a weld joint. More for the hobbyist, hole saws can be used with a drill press or, for portability, with a hand-held drill. Multiple corresponding hole saws must be used to make notches with... Read more...

Cutting exotic alloys
But sometimes this common process can be puzzling, especially when the fabricator is cutting titanium or other alloys. Tubing may be cut successfully in one production application, but the next time the result is galling and extremely short blade life. If an operator understands why this... Read more...

Sawing structural and architectural tubing
Figure 1 The circular saw is a commonly used option for cutting structural materials, including (top) solid H beams, and both round (middle) and rectangular (bottom) hollow materials. Architectural tubing is something of a mixed blessing: On the one hand, the material is... Read more...

Cutting through the obstacles
Of all the materials that can be cut on industrial band saw machines, structural steels—such as pipe and tubing, plate, angle and channel iron, and I beams—are among the most common and challenging. The challenges often arise when a blade encounters changes in the cross... Read more...

Increasing productivity on your cutoff saw
If you are sawing tube or pipe in substantial quantities, you most likely have a cutoff saw to do the work. As with all of your machinery, your goal is to get the most out of it, and that takes some special consideration. Tubes and pipes are hollow workpieces, so each cut consists of three... Read more...
