The acceptance level of pipe line girth weld defects revealed by non-destructive testing is commonly based on workmanship quality control. Unfortunately, workmanship defect acceptance levels are based on experience and are, by necessity, both arbitrary and often conservative.\u003c\/p\u003e\n\n\u003cp\u003eThis report presents the results of an experimental study of the failure behavior of 11.6 mm (0.457 in.) pipe segments taken from 36-inch diameter pipes with defects in the girth weld. Small-scale and fatigue pre-cracked, curved, wide-plate test specimens were used. The objectives were to: (1) determine the effect of pipe and weld metal yield strength differences on girth weld performance; (2) verify the assumption that the CTOD test is a reliable indicator of girth weld performance; and (3) evaluate the usefulness of the Charpy V-Notch test for predicting girth weld failures.\u003c\/p\u003e","brand":"PRCI Store","offers":[{"title":"Default Title","offer_id":44362015047758,"sku":"15058","price":995.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/prci-store.myshopify.com\/products\/l51685-effect-of-weld-metal-matching-on-girth-weld-performance-volume-ii-experimental-investigation","provider":"PRCI Store","version":"1.0","type":"link"}
