Sensor integration for robotic laser welding processes

摘要: The use of robotic laser welding is increasing among industrial applications, because its ability to weld objects in three dimensions. Robotic involves sub-processes: seam detection and tracking, process control, inspection. Usually, for each sub-process, a separate sensory system required. systems leads heavy bulky tools, contrast compact light that are needed reach sufficient accuracy accessibility. In the solution presented this paper all subprocesses integrated one multipurpose head. This multi-purpose tool under development consists head, with sensors inspection, while also carrying interfaces control. It can provide relative position work piece three-dimensional space. Additionally, it cope occurrence sharp corners along path, which difficult detect conventional equipment due measurement errors robot dynamics. will be mainly elaborated.
