Phased array (PAUT)
Phased array ultrasonics is an advanced method of ultrasonic testing that is commonly used in industrial nondestructive testing. The beam from a phased array probe can be focused and swept electronically without moving the probe. The beam is controllable because a phased array probe is made up of multiple small elements, each of which can be pulsed individually at a computer-calculated timing and is generally regarded as a more reliable method of ultrasonic testing.
Time-of-flight diffraction (TOFD)
Time-of-flight diffraction method of ultrasonic testing is a sensitive and accurate method for the non destructive testing of welds for defects. Measuring the amplitude of reflected signal is a relatively unreliable method of sizing defects because the amplitude strongly depends on the orientation of the crack. Instead of amplitude, TOFD uses the time of flight of an ultrasonic pulse to determine the position and size of a reflector.
Rope access (RA)
Rope access is a form of work positioning, initially developed from techniques used in climbing and caving, which applies practical ropework to allow workers to access difficult-to-reach locations without the use of scaffolding, cradles or an aerial work platform. Rope access technicians descend, ascend, and traverse ropes for access and work while suspended by their harness. Sometimes a work seat may be used. The support of the rope is intended to eliminate the likelihood of a fall altogether, but a back-up fall arrest system is used in case of the unlikely failure of the primary means of support. This redundancy system is usually achieved by using two ropes – a working line and a safety line.
