1 Scope

This standard specifies the method of using eddy current video integration technology to detect metal composite welds, including principles, personnel requirements, and testing equipment. Preparation, test procedures, result evaluation, test report. This standard is applicable to the combination of two or more bulk metal materials by welding, explosion, rolling and other forming techniques at the interface. Detection of butt welds between formed metal composite products. This standard does not apply to the detection of the above-mentioned metal material composite interface. This standard does not apply to weld inspection of metal matrix composite materials.
