Eddy current testing strategies for copper tube

March 11, 2008

By:

If you are a copper tube producer, you know you need to use nondestructive testing methods, but you might not be aware of all the possibilities in how they are used. First off, should you check the material before or after it is processed? What are the advantages and disadvantages of each testing point? Should you test it at both places? And second, can testing do more than help you prevent shipping poor-quality product?

Aluminum Workshop: Preventing porosity in humid environments

March 11, 2008

By:

Q: I'm having problems with excessive porosity when TIG welding aluminum. My friend says it comes from water vapor in the air (it's very humid here) being broken down by the arc. Is this true? It sounds pretty far-fetched.A: I hope you didn't bet on this one. If you did, get ready to pay up. All...

Automation in tube and pipe welding

March 11, 2008

By: ,

Robots make a lot of sense for tube and pipe welding. The return on investment for a typical robot system can be seen usually within six to 24 months, depending on the parts, complexity of the system, and learning curve of the manufacturer. Quality improvements are typically seen immediately. In addition, by tracking the process, manufacturers can make changes to improve production time and determine the throughput of the system for accurate part production projections.

Setup or cover-up?

March 11, 2008

By:

Setting up the tooling for a tube or pipe bending machine isn't as simple as it seems. Many variables are involved, making this a difficult task. A further complication is the tendency for many operators to adjust various pressure settings to compensate for poor tooling setup. The bend might turn out okay, but at a cost—a loss of process control and shortened tool life. Using a simple four-step setup process is the key to good bending, process control, and optimal tool life. This setup procedure also facilitates troubleshooting.
