This Bulletin represents many years of effort by the experts of the Joint Working Group on Fatigue Design Rules. The main points are: on structural hot spot stress, Consideration of aluminum at the effective notch stress method, improvement techniques and multi-axial loading. WRC supports USA participation in IIW via the American Council for IIW, a collaborative body of WRC, the American Welding Society and the Edison Welding Institute. The Bulletin is published under an agreement between WRC and IIW. Commission XIII: Fatigue Behavior of Welded Components and Structures consists of the following Sub-Commissions and Working Groups: Fatigue Testing and Evaluation of Data for Design; Techniques for Improving the Fatigue Strength of Welded Joints; Hot-Spot Stress Method in Fatigue Analysis of Welded Components; The Influence of Weld Defects in Fatigue-Loaded Structures; Life Extension of Welded Structures by Repair, Retrofitting and Structural Monitoring; Fatigue Design Rules. The International Institute of Welding (IIW) has for sixty years served as a remarkable instrument for professionals from many nations to exchange information, work on common problems and prepare publications with recommendations for best practices associated with welding.

The ferrite predicting diagrams are developed by calculations that use chemical analyses and measured ferrite content, then correlating composition and ferrite content. Since both composition and ferrite content are measured, each input data point used in developing the correlation has a degree of uncertainty associated with it. The uncertainty in ferrite measurement and approaches to make it as reproducible as possible were considered in great detail in WRC Bulletin 318. A series of predicting diagrams have been developed using chemical composition and measured ferrite content, including the Schaeffler Diagram (1949), the DeLong Diagram (1973) and the WRC-1988 Diagram. The latter was first published in the Welding Journal in December, 1988 (hence the name "WRC-1988 Diagram") and then was more completely described, with its supporting data, in WRC Bulletin 342. Each successive diagram was considered to be an improvement on the preceding diagram, but the degree of uncertainty in each diagram remained somewhat unknown.
