NEW IPG's QCW Fiber Laser

Recipient of 2010 Prism Award for Photonics Innovaton

IPG’s new quasi continuous wave (QCW) fiber lasers are ideal for spot welding, seam welding & drilling in the long pulse operation mode. These air-cooled, compact units are substantially more cost-effective than conventional YAG lasers due partly to >30% wall-plug efficiencies and maintenance-free operation.

The QCW fiber lasers are available for requalifying existing lamp-pumped processes at IPG’s application facilities and applications labs. IPG's QCW Series also features a highly cost-effective OEM module. Retrofit services, including engineers familiar with system integration, are available to help customers replace older production lasers with energy-efficient fiber lasers from IPG.
