Nippon Avionics Co. Ltd. announced on August 5 new Fiber Laser Welder LW-F300, which enables non-contact micro welding of metallic materials and is suitable for use in manufacturing smartphones and other information devices. It is also suitable for use in the manufacturing process of electronic components, rechargeable batteries, and fuel batteries for the automobiles which are becoming lighter and more computerized to meet the increasing demand for eco-friendly cars.

Among laser welders whose demand has increased in recent years, fiber laser welders have become popular because of their narrow beam diameter and high energy density features that realize high-quality welding of micro work pieces and highly reflective material such as aluminum and copper. The new product offers excellent stability and weldability by using a unique optical power high-speed digital feedback control function. This is an industry first for single mode fiber laser welders with an air-cooling structure.

As of August 2014, according to own research. Applications: Sealing of aluminum cases, Rechargeable battery, laminate, Fuel cell metal separator, Welding of the diode terminal, Rechargeable battery welding of secondary cell battery tab, Electronic components, Automotive electrical equipment and Medical electronic components. New Product Features: 300W high-quality single-mode laser, Stable welding operation even when ambient temperature changes or immediately after laser start-up, Air-cooled, space-saving desktop design; Normal incidence to the work is possible, Supports seam welding and high-speed welding and Energy-saving, low power consumption.
