AMADA WELD TECH, a manufacturer of equipment and systems for welding, marking, cutting, sealing, and bonding, is integrating blue laser technology into its suite of micro welding technologies. This innovation leverages the 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 such as 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 1500 Watts, and with capabilities extending up 4000 Watts for industrial applications. Feasibility studies can be run in the company’s Western Technical Center in Monrovia. The 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 suited for applications in the electronics, medical device, and automotive industries. The unique wavelength can also be used for other applications.
