摘要: 某机防喘压力信号管荧光渗透检测过程中，零件尚未进行任何加工时，常发生不同单位之间的检测结论不一致的现象。为解决此问题，采用理论和工艺试验相结合的方法，对产生结论不一致的原因进行了分析，并依据原因制定了合理而有效的解决方法。Abstract: During the fluorescent penetrant inspection of signaling lead pipe of anti-asthmatic pressure, different F.P.I results for the parts can often be presented among the different production departments even the parts to be inspected have not been undertaken any procession. This paper aims to solve the above-mentioned problems and to analyze the reason of such different results by combining theoretical study with process examination. Some reasonable and effective methods based on the reason analysis were deduced.
