Coherent | Copper Welding With IR Adjustable Ring Mode (ARM) Fiber Lasers

Copper offers a unique combination of electrical, thermal, mechanical and cost characteristics, which is why it is used throughout electric vehicles – in motor stators and inverters, in power distribution systems and within batteries. But, copper’s high electrical and thermal conductivity have also made it challenging to weld with fiber lasers. Solid-state green lasers have emerged as a possible alternative for copper welding, but their practical limitations lead to a higher cost of ownership. The Coherent ARM Laser brings all the cost, reliability and practical advantages of fiber laser to challenging copper welding tasks. Tests have proven that the dual-beam of the ARM Laser, with a high brightness center spot, can efficiently weld copper without the process instabilities that fiber lasers have.
