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.
