摘要

随着钛及钛合金的广泛应用，钛和钛合金焊接技术越来越受重视，相应焊接标准的制定和应用受到了各行业的关注。我国现有标准涵盖了焊接材料（焊丝）、焊接工艺方法和焊接缺陷的无损探伤三个方面，已经颁布的国家标准共7项，其中3项是自主制定的标准，其他4项是ISO转化的。概述了钛及钛合金用焊接材料标准，并对钛及钛合金焊接工艺方法及焊缝缺陷的无损探伤国家标准进行了综述。从整体来看，现有标准数量仍然存在不足，例如厚板或超大厚板的电子束焊接工艺、薄板构件表面焊接缺陷的荧光探伤方法等都缺少相应的标准，建议尽快予以补充完善。

Abstract

With the wide application of titanium and titanium alloy, the welding technology titanium and titanium alloy is paying more and more attention, and the formulation and application of the corresponding welding standards has been the attention of various industries. At present, China's existing standards cover three aspects: welding materials (welding wires), welding process and nondestructive testing of welding defects. Seven national standards have been issued, three of which are independently formulated, and the other four are the standards coming from ISO transformation. The standards of welding materials for titanium and titanium alloys are summarized, and the national standards for welding process and non-destructive testing of weld defects for titanium and titanium alloys are comprehensively reviewed. On the whole, the number of existing standards is still insufficient, such as the electron beam welding process standard for the thick plate or ultra-thick plate, the fluorescent testing method of surface welding defects of thin sheet components, all of them are lack of corresponding standards. It is suggested to be supplemented and improved as soon as possible.
