| Popis: | High strength and low alloy steels are commonly used in the manufacture of tubes, which are standardized by the API standard for oil and gas transport systems. The high yielding limits, high tenacity at low temperatures and the smaller thicknesses, allow the use of ducts with larger diameters and subjected to higher internal pressures, thus increasing their efficiency in the transport of fluids. This paper deals with the identification of the best temperatures applicable to stress relief and quenching and tempering treatments that optimize mechanical properties in circumferential welded joints, through Vickers traction and Charpy impact tests with V-notch “. In addition, the specimens will be characterized metallographically to correlate the mechanical and microstructural properties found in the different regions of the welded joint. |
