焊接科学及技术和人类的其他活动一样是全球化的。在面向全球焊接工作者的友谊和精神鼓舞下，我们收集和组织了我们自己以及全球的很多同行和科学家的知识和经验写成此书。
我们感谢兰州理工大学陈剑虹教授和他的同事，他们让以汉语为母语的工程技术人员和科学工作者能更方便地获得本书的知识并丰富它，以进一步推进不锈钢焊接的科学和技术的发展。

To Chinese readers
The science and technology of welding is as global as that of any other human activity.lt is in a spirit of friendship towards all people in the global welding industry that we have collected and organized our personal knowledge and experience and that of many other colleagues and scientists around the globe in writing this book. We are indebted to Professor Chen Jianhong of Lanzhou University of Technology and his colleagues for making it possible for engineers，scientists and others whose native tongue is Chinese to more easily access this knowledge and build upon it to further advance the science and technology of welding stainless steels.
