本公告报告了与焊接和焊接部件性能有关的两个重要组织的活动。本公告包含以下报告:报告1:不锈钢药芯焊丝焊接金属的高温性能调查和日本焊接工程学会的指南报告2:铋对药芯钢焊接件高温性能影响的立场声明J.C.M.Farrar、A.W.Marshall和Z.Zhang（附录:IIW循环:不锈钢FCW焊缝中的铋）。日本焊接工程学会承认，在化工和石油应用中，不锈钢部件出现裂纹的报告非常频繁。 其委员会积极调查此事，以查明并纠正原因。通过合作和数据共享活动，他们确定了铋的作用，并为FCAW应用制定了适当的指南。他们并没有就此止步。该组织的主要成员在国际上的重要工程论坛上报告了这项工作；在美国石油学会、压力容器研究委员会、IIW和其他合适的场所。他们迅速而专业的努力值得赞扬。在IIW会议上，第九委员会审查了工作，扩展了数据库，并认识到需要建立铋分析限值。进行了铋分析循环试验。 IIW的全貌？可从本文件第2号报告中获取相关信息。焊接研究委员会很高兴提请工程界注意焊剂成分控制的必要性，以及这项工作提供的高温失效模式的新见解。JWES提供的指南应有助于防止未来的故障和开裂。

This Bulletin reports on activities of two important organizations concerned with welding and the performance of welded components.This bulletin contains the following reports:Report 1: Investigation on High Temperature Properties of Weld Metals of Stainless Steel Flux-Cored Wires and Guidelines by The Japan Welding Engineering SocietyReport 2: Position Statement on the Effect of Bismuth on the Elevated Temperature Properties of Flux Cored Steel Weldments (with Appendix on IIW Round Robin: Bismuth in Stainless Steel FCW Welds) by J. C. M. Farrar, A. W. Marshall, and Z. Zhang.The Japan Welding Engineering Society recognized the unusual frequency of reports of cracks in stainless steel components in chemical and petroleum applications. Its committees vigorously pursued the matter to identify and correct the causes. Through cooperative and data sharing activities they identified the role of bismuth and established appropriate guidelines for FCAW applications. They did not stop there. Leading members of the organization reported the work internationally in important engineering forums; at the American Petroleum Institute, the Pressure Vessel Research Council, IIW and other appropriate venues. They are to be commended for their prompt and professional endeavors.At the IIW, Commission IX reviewed the work, expanded the database and recognized the need to establish bismuth analysis limits. A bismuth analysis round robin was performed. The full picture of IIW?s discussions may be gained form Report No. 2 herein.The Welding Research Council is pleased to bring to the attention of the engineering community the need for control of flux composition and the fresh insights into elevated temperature failure modes this work offers. The Guidelines provided by JWES should help prevent future failures and cracking.
