Laser Welding Applications

While the beginning of the LASERDYNE® product line can be traced to laser welding, most associate LASERDYNE with laser cutting and drilling for aerospace applications. Over the more than 37 year history of what is now Prima Power Laserdyne, we have supplied laser welding systems for aerospace (engine and airframe), electronics, fluid couplings, and medical device applications using CO2, Nd:YAG, and fiber laser sources.

This section contains links to articles from our Applications Engineering group to help you evaluate and apply laser welding for metals.
