Available in PDF, EPUB and Kindle. Book excerpt: It appears that the characteristics of the toe of the weld controls the fatigue crack initiation and propagation phenomena in the as welded specimens; and the size, and distribution and possibly location of the largest pore(s) control the fatigue crack initiation and propagation phenomena in weld reinforcement removed specimens.

Book excerpt: The work to be performed is the fatigue testing of aluminum alloy weldments containing various amounts of porosity. Approximately ninety specimens will be tested. The program is divided into three subprograms. Subprogram 1 involves 18 sound specimens to be tested with the reinforcement on. Subprogram II involves 36 specimens containing various levels of porosity to be tested with the reinforcement removed. Subprogram III involves 36 specimens containing various levels of porosity to be tested in the as-welded state. In each subprogram the following tasks will be performed in the following sequence: test specimen preparation (matching), nondestructive evaluation (x-radiography), fatigue testing, post-test examination (porosity level determination, fractography).

This book was released on 1975 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of the investigation indicate that 5083-5183 welds subjected to fatigue are little affected by porosity if the weld reinforcement is left in place. The weld reinforcement itself is the critical and fatigue limiting notch. Most welds tested with their reinforcement removed gave longer fatigue lives than as-welded tests regardless of porosity level. Porosity most influenced the fatigue lives of the reinforcement removed tests at the lowest stress levels. The radiographic standards currently in use by the U.S. Navy were found to be effective in insuring superior results with reinforcement removed welds. Conversely, few reinforcement removed welds which failed these standards gave shorter fatigue lives than porosity-free, as-welded welds.

Available in PDF, EPUB and Kindle. Book excerpt: The effects of environment on fatigue behavior are quite intimately related to such test variables as stress intensity, cyclic frequency, and temperature. The effect of these variables has been shown to be quite complex. However, a consistent pattern of behavior is beginning to emerge which, it is hoped, will lead to a considerably changed understanding of the corrosion-fatigue process. It is considered probable that an increased understanding of the corrosion-fatigue process will also contribute measureably to an improved understanding of general fatigue processes. Material variables such as composition, directionality of properties, and microstructure, have important effects on corrosion-fatigue behavior of aluminum alloys. However, it appears that these variables, at least in gaseous environments, may be important largely because of their effects on the mechanical behavior of aluminum alloys. On the other hand, studies in seawater suggest that these variables become increasingly important as the corrosive nature of the environment increases. This memorandum discusses in detail the effects of both test variables and material variables on corrosion fatigue. In addition, current theories of corrosion-fatigue mechanisms are outlined, and several methods of preventing corrosion fatigue are suggested. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: During the last eight years, a number of research studies have been conducted on the fatigue behavior of aluminum alloy weldments under the guidance of the Aluminum Alloys Committee of the Welding Research Council. The initial study was a comprehensive review of the current (1970) state of knowledge and the development of research needs. The additional studies have included investigations into the effect of weld orientation (longitudinal versus transverse), thickened plates, and weld defects on fatigue behavior. This paper provides a summary of these five studies.
