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，使用气体保护金属极电弧焊（短路过渡模式），根部采用氩气加25%二氧化碳保护，然后采用药芯焊丝电弧焊（球状过渡模式），天平采用氩气加25%二氧化碳保护。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 gas metal arc welding (short circuiting transfer mode) with Argon plus 25% Carbon Dioxide shielding for the root followed by flux cored arc welding (globular transfer mode) with Argon plus 25% Carbon Dioxide shielding for the balance. It cites the base metals 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 application.
