Influence of PWHT Parameters on the Mechanical Properties and Microstructural Behavior of Multi-Pass GTAW Joints of P92 Steel. [PDF]

Materials (Basel), 2022
The 9% Cr steels were developed for ultra-supercritical (USC) power plants to meet the requirements of high operating temperature and pressure. These steels are produced to operate at high temperatures where impact toughness is not a concern; however, it

Effect of PWHT on the dissolution of δ-ferrite in the welded joint of 12Cr–1Mo steels for steam turbines

Journal of Materials Research and Technology, 2021
In this research work, the optimal parameters of post welding heat treatment (PWHT) for 12Cr–1Mo Steel in the welding condition are determined. The PWHT aims to decrease δ-ferrite percentage in the interface of the heat-affected zone (HAZ) and partially ...

Influence of welding procedure and PWHT on HSLA steel weld metals

Journal of Materials Research and Technology, 2019
The development of consumables for welding of high strength steels represents a continuous challenge taking into account the great variety of alloy systems. In this regard, there are many applications, such as offshore structures, where the welding is still preferably done by the SMAW process. In order to evaluate the properties of weld metals obtained
