In that project, the performance of modern systems for mechanized ultrasonic inspection of girth welds in pipelines was evaluated with the emphasis on the weld root, which can be considered historically as the most difficult part of the weld when it comes to conventional ultrasonic inspection. In the current project, this was extended to the entire weld. Already in report PR-220-9123, it was stated that a structured evaluation would also help to arrive at a generic approval of mechanized UT systems for use in pipeline industry, to reduce or replace job-specific qualification tests. This point is still valid. The results of the first project, and hopefully also of this one, will be an important basis for international efforts currently being undertaken to develop such approvals, as well as to arrive at adapted acceptance criteria for weld defects. The current project was, similarly to the previous one, built around a number and a variety of representative test welds, using different welding techniques. These were inspected with Rotoscan, also using improvements (such as simultaneous TOFD), partly initiated on the basis of the work done in the previous project, and with radiography. They were then destructively tested for correlation with the NDE results.\u003c\/p\u003e","brand":"PRCI Store","offers":[{"title":"Default Title","offer_id":44361979232334,"sku":"15575","price":995.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/prci-store.myshopify.com\/products\/l51776-evaluation-of-ultrasonic-technology-for-volumetric-weld-inspection-of-pipeline-girth-welds","provider":"PRCI Store","version":"1.0","type":"link"}
