Book Synopsis The Relationship of Weld Metal Hardness, Residual Stress and Susceptibility to Stress-corrosion Cracking in a Hydrogen Sulphide Environment in A 516 GR 70 Carbon Steel Shielded Metal-arc Welded Joints by : Deon Johan De Beer
Download or read book The Relationship of Weld Metal Hardness, Residual Stress and Susceptibility to Stress-corrosion Cracking in a Hydrogen Sulphide Environment in A 516 GR 70 Carbon Steel Shielded Metal-arc Welded Joints written by Deon Johan De Beer and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In the petrochemical industry, carbon steels exposed to H2S environments may be susceptible to stress-corrosion cracking. A tensile residual stress and high hardness increases the risk of cracking in H2S environments. NACE SP 0472 limits weld metal hardness to 210 HV10 (200 HB) and heat-affected zone hardness to 250 HV10 to prevent stress-corrosion cracking of carbon steel welds in H2S. The hardness is controlled by the weld thermal cycle or by a post-weld heat treatment. In this project, the effect of hardness on the susceptibility to stress-corrosion cracking was investigated by increasing electrode strength systematically and measuring residual stress in the weld metal in the as-welded state. Samples were manufactured from SA 516 Gr 70, a carbon steel used extensively in the petrochemical industry. Heavily clamped plates were welded to minimise distortion and to maximise residual stress. The weld metal hardness was increased by using E6013, E7018-1, E8018-B2 and E9018-B3 electrodes without a post-weld heat treatment. Mechanical tests included all-weld and transverse tensile tests, impact strength and hardness testing. As the nominal strength of the weld metal increased, the all-weld tensile strength increased from 512 to 829 MPa, while the yield strength increased from 443 to 659 MPa. The average weld metal hardness increased from 177 to 317 HV10. The transverse tensile strength was between 511-517 MPa, while the yield strength (in the transverse direction) was between 360 and 382 MPa. Residual stresses of the welded joint were measured by neutron diffraction in the through-thickness, longitudinal and transverse direction. The Von Mises theorem evaluated the principle residual stress. Results indicate that the residual stress in the weld metal may be up to 99% of the yield strength. For stress-corrosion cracking, the samples were submerged in the standard TM0177-2005 test solution for 30 days. The only sample to crack was the E9018, with an average weld metal hardness of 317 HV10. The study results were consistent with the NACE SP0472 specification and earlier publications.

Book Synopsis Failure Mechanisms of Advanced Welding Processes by : X Sun
Download or read book Failure Mechanisms of Advanced Welding Processes written by X Sun and published by Elsevier. This book was released on 2010-07-15 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many new, or relatively new, welding processes such as friction stir welding, resistance spot welding and laser welding are being increasingly adopted to replace or improve on traditional welding techniques. Before advanced welding techniques are employed, their potential failure mechanisms should be well understood and their suitability for welding particular metals and alloys in different situations should be assessed. Failure mechanisms of advanced welding processes provides a critical analysis of advanced welding techniques and their potential failure mechanisms. The book contains chapters on the following topics: Mechanics modelling of spot welds under general loading conditions and applications to fatigue life predictions, Resistance spot weld failure mode and weld performance for aluminium alloys, dual phase steels and TRIP steels, Fatigue behaviour of spot welded joints in steel sheets, Non-destructive evaluation of spot weld quality, Solid state joining - fundamentals of friction stir welding, Failure mechanisms in friction stir welds, Microstructure characteristics and mechanical properties of laser weld bonding of magnesium alloy to aluminium alloy, Fatigue in laser welds, Weld metal ductility and its influence on formability of tailor welded blanks, Joining of lightweight materials using reactive nanofoils, and Fatigue life prediction and improvements for MIG welded advanced high strength steel weldments. With its distinguished editor and international team of contributors, Failure mechanisms of advanced welding processes is a standard reference text for anyone working in welding and the automotive, shipbuilding, oil and gas and other metal fabrication industries who use modern and advanced welding processes. Provides a critical analysis of advanced welding techniques and their potential failure mechanisms Experts in the field survey a range of welding processes and examine reactions under various types of loading conditions Examines the current state of fatigue life prediction of welded materials and structures in the context of spot welded joints and non-destructive evaluation of quality
