RSWA is an ultrasonic device designed for quality control and NDE of resistance spot welds. RSWA is as a portable and simple-in-operation device capable of producing images of spot weldâs internal structures. In addition to live on-screen image, this device performs estimation of the nugget diameter and compares it with predefined minimum nugget requirements. Using the unique technology of multi-channel ultrasonic matrix transducer, RSWA collects data from the surface and from the internal structures of the nugget. Special algorithms use this data to reconstruct the image of the spot weld and estimate the average diameter of the nugget area in real time.
Repetitive strain injuries (RSI) are a family of injuries affecting tendons, tendon sheaths, muscles, nerves and joints. They cause persistent or recurring pains most commonly in the neck, shoulders, forearms, hands, wrists, elbows and lower limbs.The term ârepetitive strainâ injury is misleading.he causes of repetitive strain injuries can be classified in the following ways: 1  Rapid movement injuries, caused by repeated rapid movements; 2  Forceful movement injuries, cause by exertion of muscle movement; 3  Static loading injuries, caused by fixed positioning with unsupported limbs.
