Resistance welding is an electrothermic process commonly used in Industry for joining sheet metal, particularly steel, in applications such as automobile bodies and chassis assemblies. The method is suitable for partial or total automation, and is very reliable. However, as with any process, problems can occur and inspection is therefore necessary. Although ultrasonic inspection of spot welds has been used for many years the technology still has problems with production rate and reliability, and is very operator dependent. The combination of an improved, more reliable ultrasonic coupling technique, Robust and reliable evaluation algorithms, and an optimised automation system has produced a family of inspection approaches which are scalable from low-volume manual operation to the requirements of a modern high speed automated car plant. Currently the system is being implemented in a number of other locations and organisations. The main challenge now is to build on initial favourable results and develop experience with differing situations, in particular the application to Aluminium and other advanced alloys.
