A selection of reliable measurement systems that are able to measure the toe radius along the weld bead in a T-jointhas been studied. The results show that the currently used methods and gauges do not provide the required accuracywhen measuring the toe radius. The gauges are handled differently by different operators – even when using a vision system– which makes the current evaluation methods subjective and unreliable.Therefore, an algorithm has been developed that assesses weld bead surface data and automatically identifies and calculatesthe toe radius and the toe angle along the weld. The results obtained by the algorithm are consistent with referencemeasurements and it is possible for the algorithm to be used in improving the process and quality control duringwelding.
