Annotation of standard text ASTM A488/A488M-24 :
This practice covers the qualification of procedures, welders, and operators for the fabrication and repair of steel castings by electric arc welding. The materials are categorized as carbon steel, carbon and carbon-manganese steel, low alloy steel, ferritic stainless steel, martensitic stainless steel, low carbon austenitic stainless steel, unstabilized austenitic stainless steel, austenitic stainless steel, duplex austenitic-ferritic stainless steel, precipitation-hardened austenitic stainless steel, nickel base alloy, steel castings, austenitic manganese. The orientation of the welds with respect to the horizontal and vertical planes of reference is classified into four positions, namely, flat, horizontal, vertical, and overhead. Four types of test shall be conducted in the qualification procedures such as tension test, bend test, Charpy impact test and radiographic test. Guided bend test specimens shall be prepared by cutting the test plate or pipe to form specimens of approximately rectangular cross section. Guided bend test specimens are of three types depending on which surface -side bend, face bend, or root bend is on the convex (outer) side of the bent specimen. A welding procedure must be set up as a new procedure and must be requalified when any of the changes in essential variables, inclusive, are made. Changes other than those listed may be made without requalification, provided the procedure is revised to show these changes. All welders and operators welding castings under this practice shall pass the welder qualification test. The welder or operator successfully performing the procedure qualification test is automatically qualified for performance.
