Laser Supplier Introduces Twin-Rod Technology for Welding Units

Upgrade can increase power in existing equipment by 20%

Successfully introduced with a line of drilling lasers, twin-rod (TR) technology is now available to upgrade a company's entire JK-series welding lasers. Developed by GSI Lumonics (Billerica, MA), the twin-rod oscillator design combines high beam quality with a compact laser head. Benefits include a smaller focal spot size, greater working distances, and enhanced processing capabilities, according to Andrew Dodd from the company's Northville, MI, office. "This is truly a new development for welding applications," says Dodd.

"It was driven by customer requests for welding solutions in ever-smaller components. The upgrade enables users to increase power in their existing units by about 20%," he says. The retrofitting process is extremely easy, he adds.

The TR upgrade includes a replacement laser head, power supply adapter heads, a single-fibre input module, a focus head with 160- or 200-mm recollimation, a focus lens, and a 15-m Luminator fibre-optic cable. The small-diameter cable does not require alignment following changeovers, and a proprietary coupling technology provides back-reflection protection during the welding of highly reflective materials.
