Additive manufacturing based on arc welding (DED-Arc) has already established itself in the world of additive manufacturing. Recent process optimizations show the increased use in a hybrid process by irradiating an additional laser beam into the active zone of the arc. Numerous publications can be found in the literature for steel, aluminum or bronze, in which, among other things, a strength-enhancing effect during this hybrid process is reported. The way in which the laser beam hits the arc, at what distance, at what angle and with what spot size appears to be random in the publications and is always chosen differently in the literature. In order to close this knowledge gap, a corresponding holder for a DED-Arc torch and laser optic was developed, which allows these geometric factors to be systematically changed and also enables the titanium alloy Ti-6Al-4V to be processed in a hybrid process. By welding individual tracks and walls with different angles, distances and spot sizes of the two energy sources, a fundamental understanding of the laser-arc hybrid process was created. The results are analyzed and evaluated on the basis of surface measurements, micrographs and the power source values. The result show that the distance between the laser and the arc has the greatest effect on the additive process stability. It also shows that a wider spot sizes range of 360-600μm can be used and that the angle of incidence of the laser beam determines the surface waviness.
