适用范围：Contains the essential welding variables for chromium-molybdenum steel in the thickness range of 1/8 through 1/2 inch in the as-welded condition, or 1/8 through 3/4 inch in the PWHT condition, using manual gas tungsten arc welding. 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 applications.
