前言有两种不同的方法可用于焊缝的无损检测(NDE)。常规的方法除与焊接过程有关的工序间检验以外,一般用于焊后的无损检测。第二种新的方法是焊接过程中的无损检测,这种方法的工艺及操作方法是结合某一焊接工艺过程而确定。在这种方法中由无损检测所获得的技术信息,可对焊接工艺参数
Preface There are two different methods that can be used for non-destructive testing of welds (NDE). Conventional methods are generally used for non-destructive testing after welding except for the inter-process inspection related to the welding process. The second new method is non-destructive testing in the welding process. The process and method of operation of this method are determined in conjunction with a certain welding process. Technical information obtained by non-destructive testing in this method can be used for welding process parameters
