Download or read book Hot Cracking Phenomena in Welds II written by Thomas Böllinghaus and published by Springer Science & Business Media. This book was released on 2008-08-07 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: Failure of welded components can occur during service as well as during fabrication. Most common, analyses of the resistance of welded components against failure are targeted at crack avoidance. Such evaluations are increasingly carried out by modern weldability studies, i. e. considering interactions between the selected base and filler materials, structural design and welding process. Such weldability investigations are particularly targeted to prevent hot cracking, as one of the most common cracking phenomena occurring during weld fabrication. To provide an international information and discussion platform to combat hot cracking, an international workshop on Hot Cracking Phenomena in Welds has been created, based on an initiative of the Institute for Materials and Joining Technology at the Otto-von-Guericke University in Magdeburg and the Division V. 5 – Safety of Joined Components at the Federal Institute for Materials Research and Testing (BAM) in Berlin, Germany. The first workshop was organized in Berlin under the topics mechanisms and phenomena, metallurgy and materials, modelling and simulations as well as testing and standardization. It consisted of 20 individual contributions from eight countries, which were compiled in a book that found a very ready market, not only in the welding community. As a consequence of increasing interest, it has been decided to establish the Workshop on Hot Cracking Phenomena in Welds as a regular event every three years embedded in the International Institute of Welding (IIW). Attached to the IIW Commission IX and II Spring intermediate meetings, the second workshop was organized in March 2007.
Download or read book Weld Cracking in Ferrous Alloys written by R Singh and published by Elsevier. This book was released on 2008-12-12 with total page 581 pages. Available in PDF, EPUB and Kindle. Book excerpt: Weld cracks are unacceptable defects that can compromise the integrity of welded structures. Weld cracking can lead to structural failures which at best will require remedial action and at worst can lead to loss of life. Weld cracking in ferrous alloys reviews the latest developments in the design, evaluation, prevention and repair of weld cracks. Part one reviews the fundamentals as well as recent advances in the areas of welding technology, design and material selection for preventing weld cracking. Part two analyses weld crack behaviour, evaluation and repair of cracking/cracked welds. The book benefits from an extensive and robust chapter on the topic of NDE and quality control that was contributed by one of the most respected non-destructive evaluation and development groups in the world. Part three covers environment assisted weld cracking. With its distinguished editor and international team of contributors, Weld cracking in ferrous alloys is a valuable source of reference for all those concerned with improving the quality of welding and welded components. In the planning and development of this book, particular care has been taken to make the chapters suitable for people from other disciplines who need to understand weld cracking and failure. Reviews the latest developments in the design, evaluation, prevention and repair of weld cracks Assesses recent advances in welding technology, design and material selection Analyses weld crack behaviour, evaluation and repair including environment assisted weld cracking
Download or read book An Investigation of the Elevated Temperature Cracking Susceptibility of Alloy C 22 Weld metal written by Morgan Leo Gallagher and published by . This book was released on 2008 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The use of nickel-base alloys has increased in recent years as the demand for high-temperature corrosion resistant alloys increases. However, the introduction of new alloys can present challenges in materials joining. During fabrication involving welding, both solidification cracking and ductility-dip cracking (DDC) cracking may occur in these alloys if proper precautions are not followed. One such nickel-base alloy is Alloy C-22, which has limited weldability data to date. Alloy C-22 is one of the most corrosion resistant Ni-Cr-Mo alloys available today, and is particularly versatile. As a result, Alloy C-22 is being considered for use in the construction of storage canisters for permanent disposal of radioactive waste in the Yucca Mountain Project. However, in such a critical application, weld related defects (such as these two forms of cracking) are simply unacceptable. This investigation examined the solidification cracking and ductility-dip cracking susceptibility of Alloy C-22 in two phases. The first phase or the investigation determined the baseline susceptibility of two commercial heats of Alloy C-22 to these two forms of weld cracking. Solidification cracking was evaluated using the transvarestraint test, and ductility-dip cracking was evaluated using the strain-to-fracture and hot-ductility tests. The alloy was found to be highly resistant to solidification cracking, yet susceptible to ductility-dip cracking in the strain-to-fracture test. However, it is noted that Alloy C-22 has not been found to be susceptible to ductility-dip cracking within industry. The second phase of the investigation examined the effects of compositional variation (specifically the variation of Mo, W, and Fe) on solidification cracking and ductility-dip cracking. This was accomplished using a combination of thermodynamic simulations and button melting experiments. The button melting experiments were coupled with a new version of differential thermal analysis known as single-sensor differential thermal analysis. Experimental results indicate that compositional variation within the limits that define the alloy as C-22 will not significantly increase the susceptibility of the alloy to solidification cracking or ductility-dip cracking.

Download or read book Hot Cracking Phenomena in Welds III written by John Lippold and published by Springer Science & Business Media. This book was released on 2011-05-03 with total page 439 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the third in a series of compendiums devoted to the subject of weld hot cracking. It contains 22 papers presented at the 3rd International Hot Cracking Workshop in Columbus, Ohio USA in March 2010. In the context of this workshop, the term “hot cracking” refers to elevated temperature cracking associated with either the weld metal or heat-affected zone. These hot cracking phenomena include weld solidification cracking, HAZ and weld metal liquation cracking, and ductility-dip cracking. The book is divided into three major sections based on material type; specifically aluminum alloys, steels, and nickel-base alloys. Each of these sections begins with a keynote paper from prominent researchers in the field: Dr. Sindo Kou from the University of Wisconsin, Dr. Thomas Böllinghaus from BAM and the University of Magdeburg, and Dr. John DuPont from Lehigh University. The papers contained within include the latest insight into the mechanisms associated with hot cracking in these materials and methods to prevent cracking through material selection, process modification, or other means. The three Hot Cracking Phenomena in Welds compendiums combined contain a total of 64 papers and represent the best collection of papers on the topic of hot cracking ever assembled.

This book was released on 1963 with total page 1613 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because cracking problems were encountered during the welding of the first HY-80 steel submarine hulls, the program to develop an HY-130/150 submarine-hull weldment was designed to include a comprehensive investigation of the composition limits within which an HY-130/150 steel will exhibit minimum susceptibility to weld-heataffected-zone cracking. Therefore, a statistically designed program was initiated to determine the effects of carbon (0.05 to 0.21%), manganese (0.30 to 1.50%), phosphorus (0.003 to 0.027%), sulfur (0.003 to 0.027%), and nickel (1.00 to 9.00%) on the weld-heat-affected-zone cracking of Laboratory cruciform specimens fabricated from 32 experimental Ni-Cr-Mo steels (1.3% Cr and 0.6% Mo).
