本标准包含厚度范围为1/8至1-1/2英寸的碳钢的基本焊接变量，根部采用氩加25%二氧化碳气体保护金属弧焊（短路过渡模式），天平采用氩加2%氧气保护气体保护金属弧焊（喷射过渡模式）。它引用了制作焊接件所需的母材和操作条件、填充金属规范以及坡口焊缝的允许接头设计。本WPS主要用于管道应用。

This standard contains the essential welding variables for carbon steel in the thickness range of 1/8 through 1-1/2 inch, using Argon plus 25% Carbon Dioxide shielded gas metal arc welding (short circuiting transfer mode) for the root followed by Argon plus 2% Oxygen shielded gas metal arc welding (spray transfer mode) for the balance. It cites the basemetals and operating conditions necessary to make the weldment, the filler metal specifications, and the allowable joint designs for groove welds. This WPS was developed primarily for pipe applications.
