The demands of differing industries bring with it the need to create effective manufacturing technologies such as the inclusion of nanosecond infrared fiber lasers in production as they offer high reproducibility, accuracy and productivity along with the all-important low cost in terms of capital and maintenance. Until now the use of nanosecond (ns) pulsed lasers has been limited but recent pioneering development by SPI Lasers saw the introduction of the master oscillator power amplifier (MOPA) in ns fibre lasers. Viewed as extremely versatile tools due to their ability to control and tailor the pulse characteristics to the requirements of applications, this is achieved through the ability KNOBS & HANDLES Extensive range in stock, fast delivery • Knobs & handles • Handwheels • Levers • Adjustable feet H_2370 Available from Hi-Q Electronics Limited engineering@hiq.co.nz 0800 766 709 www.hiqknobs.co.nz to change the pulse duration and frequency. Regardless of the thickness, or how different the chemical and mechanical properties of two dissimilar metals, successful welding can be achieved using ns fiber lasers. The nanosecond welding process offers multiple options in join design that includes weld geometry flexibility, for example, joining copper on 718 super alloy, aluminium on brass, aluminium on copper, stainless steel on aluminium, stainless steel on copper, titanium on aluminium, and titanium on copper. SPI RedEnergy pulsed lasers provide an economic and effective solution to the welding of dissimilar metals. SPI products are available in Australia and New Zealand from Raymax Applications.
