I have a project in my business with weld seam detection on steel tubes before bending. We are already using color sensors and the combination of magnetic flux leakage and eddy current technology. Neither of the two satisfies the requirements we need for a stable production. Because of production volume, on some of the machines we depend on 99.9998%. Does anyone have experience with other types of equipment that can do the job? We have temporarily solved the problem by interrupting the search program when the weld is not found within 10 seconds, but then we have a production stop which is not preferable.
