Today, automated robot welding of components with low tolerances in series production is state-of-the-art. But turning to small-lot production particularly of parts with high tolerances, plant construction is just at the beginning of building economically efficient automated solutions. While weld seam tracking is well established for the described problem, geometric recognition of weldments is not yet solved satisfactorily. The following article will present an optimisation approach of a laser sensor guided and programmed robot welding system which was developed within the project Roprof at the TU Dortmund. With this development, a working prototype robot weld system was build by a steel construction company as well as an additional demonstration software showing the potential and transferability of adjusted geometric location of weldments for industrial applications.
