Abstract

New weld inspection methods superceding visual inspection are presented. Laser‐based sensor technology contained in a handheld scanner for pre‐ and post‐weld inspection enables measurement of joint preparations or finished welds and validation of their geometry against pre‐set limits, as well as the analysis of three‐dimensional images of weld beads. The range of laser‐based sensor equipment available extends to full robotic weld inspection systems, which are applied in arc and laser welding processes on production lines, such as in the automotive industry. The benefits of these systems include higher repeatability, a permanent record for generating trending information, and the production of data helpful in reducing welding consumables used, resulting in significant savings to manufacturers.
