AMADA WELD TECH, manufacturer of equipment and systems for welding, marking, cutting, sealing, and bonding, announced the integration of blue laser technology into its suite of micro welding technologies. This innovation leverages the unique properties of blue diode lasers to deliver superior performance in welding highly reflective materials, notably copper.
Traditional infrared lasers, such as Nd:YAG and fiber lasers, emit light in the 1064-1070 nanometer range, which is less efficiently absorbed by materials like copper, leading to increased energy consumption and potential processing challenges. In contrast, blue lasers operate at a wavelength of approximately 450 nanometers, providing better absorption of the radiation for materials like copper. This results in more efficient energy utilization, reduced heat input, reduction of spatter, and enhanced precision in micro welding tasks.
AMADA WELD TECH's blue laser systems offer power levels ranging from up to 1500W, and with capabilities extending up 4000W for industrial applications. Feasibility studies can be run in the company’s Western Technical Center in Monrovia. Capability in the technical center includes power levels up to 1500W and spot sizes between 200 to 500 microns in diameter. This enables precise joining of delicate components, making it ideal for applications in the electronics, medical device, and automotive industries. The unique wavelength can also be used for other applications.
"The introduction of blue laser technology into our product portfolio marks a significant advancement in our micro welding capabilities," says Dr. Mark Boyle, director, Product Engineering and Applications at AMADA WELD TECH. "This technology not only enhances our ability to weld challenging materials like copper but also provides a unique micro joining solution that improves production efficiency and throughput for our clients."
