This document presents the results of recent copper welding tests which were performed successfully with a new type of adjustable ring mode (ARM) fiber laser having a high brightness center beam. Here, the high brightness ARM laser delivered excellent weld quality, and better penetration at various weld speeds, than commercially available kW class green lasers. These results indicate that this technology could bring all the cost, reliability, and practical advantages of fiber lasers to the demanding task of copper welding.
