Abstract

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.
