The four ultrasonic techniques for sizing flaws in pipeline girth welds were evaluated against a set of seventeen girth-weld flaws that included cracks, incomplete fusions, inadequate penetrations, slag inclusions, a gas pocket and a porosity. The correlations were poor for the results obtained by two versions of the decibel-drop technique. The best results were obtained from the supplemented satellite-pulse observation technique.\u003c\/p\u003e","brand":"PRCI Store","offers":[{"title":"Default Title","offer_id":44367606382670,"sku":"18149","price":50.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/prci-store.myshopify.com\/products\/l51443-evaluation-of-flaw-depth-measurement-accuracy-using-ultrasonic-inspection-techniques-1","provider":"PRCI Store","version":"1.0","type":"link"}
