Achieving the required strength overmatch, ductility and low temperature toughness in WM becomes a challenge as the strength of the pipe increases. The introduction of higher productivity advanced pulsed gas metal arc welding (GMAW-P) processes adds further complications from the associated cooling conditions of the weldment. An improved understanding of WM systems (compositions, microstructures, essential variables, etc.) required for the successful large scale production of high strength pipeline field girth welds is needed for new and demanding pipeline construction projects.\u003c\/p\u003e\n\n\u003cp\u003eThis work provides details of the characterization of experimental girth welds produced for a major consolidated program of research with two primary areas of focus related to the welding of high strength steel pipelines. The first aims to update weld design, testing, and assessment procedures [1]. The second aims to optimize welding solutions for joining high strength steel X100 (Grade 690) pipe by examining the welding process and material variables that lead to variation in weld properties [2]. Characterizing and understanding the microstructures that develop in these high strength steel welds is a key element in the overall investigation to reduce variation in weld properties through better control of the welding process.\u003c\/p\u003e","brand":"PRCI Store","offers":[{"title":"Default Title","offer_id":44372285227086,"sku":"18455","price":100.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/prci-store.myshopify.com\/products\/l52352-microstructure-and-hardness-characterization-of-girth-welds","provider":"PRCI Store","version":"1.0","type":"link"}
