How to use hi-lo welding gauge
There is always a need to inspect manufactured components for defects or degradation at various stages such as during production, post-production and in-service. Non-destructive testing (NDT) is undertaken for reasons of safety, risk management and critical path management and is usually performed within the stages of post-production and in-service. To highlight this point it is useful to consider welded steel plates, which are typically inspected using several techniques of which ultrasonic inspection is probably the most important. However, conventional ultrasonic testing still has some serious shortfalls, the most significant being the time it takes to inspect samples and the associated sample preparation cost of grinding the weld caps.
