無損檢測手冊簡介

1、無損檢測手冊 無損檢測手冊簡介 簡介無損檢測手冊是機(jī)體、發(fā)動機(jī)和部件制造廠編制的無損檢測程序，不僅包含主要的和輔助的結(jié)構(gòu)，而且包括專利的部件的檢測程序，是機(jī)體、發(fā)動機(jī)和部件制造廠在真實的構(gòu)件上和原位實際狀態(tài)下經(jīng)過驗證可以實施的程序，每種機(jī)型均有相應(yīng)的無損檢測手冊，制造廠家定期進(jìn)行更新和修正，在兩次定期進(jìn)行更新和修正之間通常發(fā)布一些臨時修正，在使用時要注意采用有效版本。除無損檢測手冊外，制造廠家也會根據(jù)產(chǎn)品的使用狀況發(fā)布服務(wù)通告，如果服務(wù)

2、通告中要求的無損檢測程序在產(chǎn)品無損檢測手冊中已經(jīng)存在，該服務(wù)通告只給出在無損檢測手冊中的零件和檢驗程序號，否則在服務(wù)通告中會與按所用產(chǎn)品手冊的相同標(biāo)準(zhǔn)給出詳細(xì)的檢測程序。作為 NDT 人員應(yīng)對所維護(hù)的機(jī)型的無損檢測手冊（NTM）有清晰的了解，能夠了解不同機(jī)型無損檢測要求的差異，掌握無損檢測手冊中各種檢測方法的通用要求，熟練應(yīng)用無損檢測手冊中各種檢測程序指導(dǎo)檢測工作。由于所有機(jī)型的無損檢測手冊都是按照 ATA 規(guī)范編寫的（ATA100 2

3、-9《無損檢測手冊》 ） ，因此不同機(jī)型的無損檢測手冊的格式基本是一樣的。下面就按照 BOEING NDTM 和 AIRBUS NTM 及 CMM 進(jìn)行介紹。一．波音系列飛機(jī)無損檢測手冊簡介下面介紹 BOEING NDTM 的組成和使用：在查閱手冊時，首先應(yīng)確認(rèn)使用的手冊是最新有效的版本，即是滿足適航要求的技術(shù)文件，這才能作為工作依據(jù)，手冊的版本號、更新日期在前言頁上可以查到，在有效頁清單中可以知道更新、修改的情況,如下圖所示 Revi
