Abstract
The invention relates to a fusion method for calibrating a composite material porosity reference block, which comprises the following steps: carrying out ultrasonic A scanning detection on the composite material porosity reference block, and judging whether the ultrasonic A scanning uniformity of the composite material porosity reference block meets the requirement or not; if yes, performing ultrasonic C scanning detection on the composite material porosity reference block, and judging whether the ultrasonic C scanning uniformity of the composite material porosity reference block meets the requirement or not; if yes, performing ultrasonic numerical evaluation on the composite material porosity reference block, and judging whether the ultrasonic porosity numerical evaluation uniformity of the composite material porosity reference block meets the requirement or not; and if yes, performing small cut sample sampling on the composite material porosity reference block, and performing optical microscopic calibration on the porosity of a small cut sample observation section to obtain a porosity calibration result of the composite material porosity reference block. According to the method, correct calibration of the composite material porosity reference block can be carried out.
