Supply chain collaborates on bending project
Figure 1
The complexity of the finished product stems, in part, from making bends on both the H plane (hard way) and E plane (easy way).
Fabrication projects don't just happen on their own; they require planning, which often involves an OEM, a fabricator, a tooling provider, and a... Read more...

No need for annealing
Fabricators are always looking for new ideas. Any new strategy, whether it involves a machine, a process, a technology, or a technique, is worth investigating if it will result in a better product or improve profitability.
New ideas aren't always easy to implement. Sometimes they are... Read more...

Learning to adapt
Although Production Cutting Services initially focused on saw-cut parts, these days it also provides machined (right) and laser-cut (left) parts. It also learned the ins and outs of drilling and plasma cutting. Manufacturing isn't the same today as it was two and a half decades ago. CNC... Read more...

Focusing on bent tubing
You have been bending tube and pipe for years, and while you're proficient at bending, you realize that you're spending too much time on quality control. Some of the parts are easy to handle and have just one or two bends, so measuring the straight sections and verifying the bend angles isn't... Read more...

Putting a few end forming basics to work
End forming processes are used to change the shape of a significant majority of fabricated tube ends. Quite often one or both tube ends must be formed to mate to another part. The mating part might be another tube, a small component such as a fuel pump, or a large component such as an... Read more...

Titanium trends
Although titanium was discovered in the late 18th century, it wasn't until 1940 that a metallurgist, Dr. William Kroll, first devised a commercially viable process for extracting the metal fromits raw ore. In the 1950s titanium was recognized for its high strength and light weight, making it... Read more...

Fact or Friction?
The tube and pipe bending process is full of variables and options, all of which you must understand and manage successfully to make the end product.
Any of these variables can make a significant contribution to the success or failure of the manufacturing process. Certain variables are... Read more...

TIG for titanium tubing
Titanium is 45 percent lighter than steel, 60 percent heavier than aluminum, and more than three times stronger than either of them. While it is much more expensive than many other metals, it has greater corrosion resistance, lower life-cycle costs, longer service life, and drastically lower... Read more...

Pour me a mandrel
A low-melting-point alloy is heated and poured into a length of tube. 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... Read more...

Minimizing wall thickness variation in seamless tubing
Reducing the amount of variation, or achieving more wall thickness consistency, can be the difference between meeting a customer's requirements or not. It also helps to reduce or even may eliminate the customer's need for subsequent processes such as machining. Seamless tube typically is... Read more...

Brazing copper tubing
This tool modifies copper fittings by making a shallow impression in the fitting wall, shortening the socket depth to 3/8 in. It should be used only for joints that will be brazed. Strength of Tube Joints Butt joints between copper tubes can be just as strong as the copper itself if... 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...

Laser welding of stainless pressure tubes
The vast majority of welded stainless steel pressure tubing is produced with the gas tungsten arc welding (GTAW) process. This process often is referred to as tungsten inert gas (TIG) welding. However, with the recent advent of reliable, high-power laser power sources, the laser beam... Read more...

Producing quality ASTM A249 and ASME SA 249 pressure tubes
Object Producing quality ASTM A249 and ASME SA249 pressure tubes takes more than just applying a stencil to the product. It requires a manufacturing process and a quality system that not only provide an excellent weld, but also condition the weld through proper cold working (forging) and... Read more...
