摘要： 目前，我国用于焊接工程的常用材料，其焊接性已基本掌握，要确保焊接质量，施焊前应进行焊接工艺评定，以评定施焊单位是否有能力焊出符合相应规程、规范和产品技术条件所要求的焊接接头。然而，国内不同行业的产品对其焊接工艺评定规定却不太一致，本文通过对国内常用的焊接工艺评定标准的对比，发现其不同点，因而在实际中应用时根据不同的要求选用不同的焊接工艺评定标准。
Abstract: At present, the weldability of materials commonly used in welding engineering has already been grasped basically, and we should make welding procedure qualification before welding when ensuring the quality of welding, so as to assess whether the welding units weld the welding joint which meets corresponding regulations, standards and the requirements of product technology conditions or not. However, there are consistent provisions of domestic different industries′ products to its welding procedure qualification. Through the comparison of domestic commonly used welding procedure qualification standards, this paper finds the differences, thus choose different welding procedure qualification standards according to different requirements in practical application.
