The possible effects of this CG-HAZ on the toughness of weld seams in Grade X80 line pipe are reviewed in reference to: 1. criteria in use by pipe producers to achieve and control the toughness of the HAZ and weld metal, 2. test methods to characterize the toughness of the weld metal and HAZ, and 3. the applicability of such test methods to Grade X80 line pipe.\u003c\/p\u003e","brand":"PRCI Store","offers":[{"title":"Default Title","offer_id":44367623258190,"sku":"15199","price":395.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/prci-store.myshopify.com\/products\/l51839-methods-for-evaluating-the-toughness-of-weld-heat-affected-zones-in-line-pipe-steels-1","provider":"PRCI Store","version":"1.0","type":"link"}
