This part of NB/T 47013 specifies the technology and quality classification requirements for X-ray computer-aided imaging testing (hereinafter referred to as "CR testing") below 450kV for fusion welded joints of pressure components of metal materials in pressure-bearing equipment. This section is applicable to CR testing of fusion welded joints of steel, copper and copper alloys, aluminum and aluminum alloys, titanium and titanium alloys, nickel and nickel alloy materials. The type of welded joint is a butt joint of plate or pipe butt weld (hereinafter referred to as "butt weld"). The CR testing of welded joints of other materials, supports and structural parts of pressure-bearing equipment can be used as a reference.
