The new frontier
Cutting and welding highly reflective materials like copper and gold with more precision is now possible with Laserline’s blue diode lasers. Combining two proven laser applications (blue and infrared lasers) has allowed for the processing of thicker materials. Now, even more applications are possible, with less energy consumption and material waste.
Better absorption
Reflective metals have long proved a challenge to process by laser, whether that’s cutting or welding. This is because the laser light is reflected away and not absorbed by the metal. But copper and gold absorb blue light 7– 20 times better than any laser in the infrared range. The resulting weld seams are smooth. Blue lasers can even process very thin foils and sheets.
A quantum leap for technology
Thanks to its high thermal and electrical conductivity, copper is a popular material used in today’s technology. It’s present in many different forms in batteries and electric cars, for example. Each component could be made of different parts that need to be connected. And it’s essential that the connections—welds—don’t cause resistance in the flow of the signal. Some applications of blue laser welding include the production of wind turbines, electric cars and jewellery.
The team at Raymax have offered us exceptional service and technical back up. We couldn’t ask for better support from a supplier.
Controlled process & result
Infrared lasers can also weld copper but require high output power, which increases the risk of mistakes and spatters. The rejection of compromised materials or parts can be more costly to manufacturers.
Because blue lasers are better absorbed by copper, the process is more controlled. The resulting weld seams are created without spatters or pore formation.
The best of both worlds
When joining thicker materials, however, blue light is less efficient and more costly. So how to solve this dilemma? Laserline developed a hybrid concept for deeper welding up to 3mm. The hybrid laser technology involves a blue light overlaid with an infrared laser. The infrared laser does the actual welding, while the blue light provides a calm molten pool for a more controlled outcome.
