Abstract

A carriage 10 includes a guide member 28 which cooperates with a tracking ring 7 on a pipe member. The carriage carries, for example, an ultrasonic, multi-transducer probe assembly 80 for the non-destructive testing of welds 8. On movement of the carriage around the pipe member, the guide member and tracking ring cooperate to ensure the maintenance of a constant geometrical relationship between the probe assembly and the weld to be tested. The carriage is driven around the pipe member by a chain 34 and sprocket wheels 32. The carriage may be modified to carry a welding torch (Figure 15, not shown). <IMAGE>
