Summary This standard specifies the X-ray photography method for fusion welded butt joints whose welding methods are gas welding, argon arc welding, and a combination of gas welding and argon arc welding (electric welding, submerged arc welding, and a combination of electric welding and submerged arc welding may also be used) , stipulates the classification of weld quality. This standard is applicable to the detection and grading activities of fusion welded butt joints with base metals of copper and copper alloys and thickness not greater than 20mm in air separation equipment. The detection and grading activities of fusion welded butt joints with other base materials and copper or copper alloys can be Refer to use.
