Test plates shall be welded using the same qualified welding procedure and electrodes that are required for the tank shell plate joints. The API 620 steel storage tank test plates need not be welded as an extension of the tank shell joint but shall be welded in the required qualifying positions. One test weld shall be made on a set of plates from each specification and grade of API620 steel storage tank construction plate material, using a thickness that would qualify for all thicknesses in the shell. Each test welded of thickness t shall qualify for plate thicknesses from 2t down to t/2, but not less than 5/8 in. For plate thicknesses less than 5/8 in., a test weld shall be made for the thinnest shell plate to be welded; this test weld will qualify plate thicknesses from t up to 2t.

This specification, in conjunction with API 650 Standard, prescribes minimum standards for the API620 steel storage tank construction design, supply fabrication, erection, and testing of field erected welded steel storage tanks complete with accessories as specified herein and as shown on attached datasheets and/or drawings.
