Translating any good idea into a practical innovation through research and development can require much persistence, dedicated effort, essential investment, and a long time. This article looks at three welding and joining innovations—hybrid laser arc welding, electron beam welding in air, and NanoFoil® joining—with decades-old roots that still are struggling for widespread acceptance.

Laser equipment specialists claim that an operator now can change the head for cutting up to 3/4-inch mild steel to welding 3-D parts in less than 15 minutes. So the laser cutting/welding equipment has made a technological leap to support the job shops looking to expand their capabilities. But how have the gas systems evolved to support these advanced capabilities?

Although a firm grasp of laser physics, metallurgy, tooling and fixturing, weld process parameters, and part strength testing is necessary to implement laser technology in any manufacturing facility, it's also critical to think of other issues that will impact the success of your laser use. Some keys to a successful laser project include involving production personnel early in the process, choosing a laser technology advocate, considering your shop's ambient environment, using trained operators and maintenance personnel, and planning for spare parts and maintenance.

The ramming machine bores into the side of the new automobile at a speed of 50 kilometers (31 miles) per hour. Within a fraction of a second, sensors situated all over the test dummy signal details of the stress load. Shortly afterward the overall results of the Euro-NCAP crash test will appear in all the specialized automobile magazines.
