Download or read book IIW Guidelines on Weld Quality in Relationship to Fatigue Strength written by Bertil Jonsson and published by Springer. This book was released on 2016-04-13 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents guidelines on quantitative and qualitative measures of the geometric features and imperfections of welds to ensure that it meets the fatigue strength requirements laid out in the recommendations of the IIW (International Institute of Welding). Welds that satisfy these quality criteria can be assessed in accordance with existing IIW recommendations based on nominal stress, structural stress, notch stress or linear fracture mechanics. Further, the book defines more restrictive acceptance criteria based on weld geometry features and imperfections with increased fatigue strength. Fatigue strength for these welds is defined as S-N curves expressed in terms of nominal applied stress or hot spot stress. Where appropriate, reference is made to existing quality systems for welds.In addition to the acceptance criteria and fatigue assessment curves, the book also provides guidance on their inspection and quality control. The successful implementation of these methods depends on adequate training for operators and inspectors alike. As such, the publication of the present IIW Recommendations is intended to encourage the production of appropriate training aids and guidelines for educating, training and certifying operators and inspectors.

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Welding structural steel components is an essential stage in steel fabrication. Residual stresses and welding defects are often associated with the welding procedure. According to the fracture toughness of the material, the level of the residual stresses and the size of the discontinuities and flaws in the steel component being welded, cracks can initiate and repair will be required. In some cases, this repair will need to be repeated if additional cracks result from the weld repair procedure. As a result, welding and steel specifications contain limits as to the material fracture toughness and the size of discontinuities in the base metal. The origin of these limits is for the most part based on studies involving commonly used steel plates of less than 25 mm thickness. Nowadays, the use of heavy steel sections composed of plates or elements greater than 50mm in thickness has increased in construction because of current design specifications that require structures to withstand loads arising from blasts impact and large earthquakes, for example, which amplify the loading demands placed on the steel structure compared to what was considered for design in past decades. Available welding specifications and procedures have been employed in the fabrication of thick steel components; nonetheless, fabricators have reported unrepairable cracks that developed after the welding procedures were completed. The increase in thickness of the welded component results in greater restraint to the expansion and contraction induced by the welding procedure, which leads to an increase in the developed welding residual stresses. Moreover, the likelihood of discontinuities and flaws in thick steel is higher than that in found in thinner plates. In addition, the variability of the fracture toughness of a material increases as the thickness becomes larger. Accordingly, the welding of thick steel components requires separate welding specifications and acceptance criteria. In this thesis, a comprehensive study is conducted based on a numerical and an experimental framework, with which the welding procedures of thick steel plates (greater than 50mm) using an automated submerged arc welding process is evaluated. A finite element simulation of the welding is developed and validated with measured results from a welding experiment. Material tensile and fracture toughness testing is conducted for thick steel plates to determine the variability in these properties. A probabilistic approach for assessing discontinuities is proposed based on fracture toughness tests, as well as a database compiled from previous and current research. The finite element simulation and discontinuities assessment approach are used for the assessment of a parametric study of the main parameters of the welding procedure. According to the results of the parametric study, four submerged arc welding procedures are recommended for welding steel plates of thicknesses from 25 to 100mm. In addition, acceptance criteria are developed for discontinuities existing in the steel plates before welding based on a performance-based approach. Moreover, two experimental investigations are carried out; the first is to determine the effect of five submerged arc welding procedures on the weld quality and material properties of the heat affected zone. The results of the experiments are in agreement with the parametric study results. Based on the weld experiment results, two welding procedure specifications are recommended for welding thick steel plates. The second experiment aims to study the effect of multiple weld repairs on the heat affected zone of the base metal. The results of this study suggests using a maximum of three weld repairs at one location in steel fabrication." --

Download or read book Friction Stir Welding written by Daniela Lohwasser and published by Elsevier. This book was released on 2009-12-18 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: Friction stir welding (FSW) is a highly important and recently developed joining technology that produces a solid phase bond. It uses a rotating tool to generate frictional heat that causes material of the components to be welded to soften without reaching the melting point and allows the tool to move along the weld line. Plasticized material is transferred from the leading edge to trailing edge of the tool probe, leaving a solid phase bond between the two parts. Friction stir welding: from basics to applications reviews the fundamentals of the process and how it is used in industrial applications.Part one discusses general issues with chapters on topics such as basic process overview, material deformation and joint formation in friction stir welding, inspection and quality control and friction stir welding equipment requirements and machinery descriptions as well as industrial applications of friction stir welding.

This book was released on 2013-01-25 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: The weld toe is a primary source of fatigue cracking because of the severity of the stress concentration it produces. Weld toe improvement can increase the fatigue strength of new structures significantly. It can also be used to repair or upgrade existing structures. However, in practice there have been wide variations in the actual improvements in fatigue strength achieved. Based on an extensive testing programme organised by the IIW, this report reviews the main methods for weld toe improvement to increase fatigue strength: burr grinding, TIG dressing and hammer and needle peening. The report provides specifications for the practical use of each method, including equipment, weld preparation and operation. It also offers guidance on inspection, quality control and training as well as assessments of fatigue strength and thickness effects possible with each technique. IIW recommendations on methods for improving the fatigue strength of welded joints will allow a more consistent use of these methods and more predictable increases in fatigue strength.
