This configuration consists of one or more robots with fixed optics. It offers good reach ability, high path accuracy and excellent flexibility. The advantage is even greater if you weld with multiple robots, also known as the "AWL beam switch management system". As the beam switches from one optic to the other the laser source is fully utilized. Products that are suitable for this configuration have relatively long distances between the welds and the welds are at various angles (3D). Recent developments with fiber laser and the significant improvement of robot safety offer serious robotized laser-weld possibilities.
