Abstract:
In the process
of studying the dynamic distribution of diffusible hydrogen in
welded zone of alloyed steels by the microcomputer, a series of
software for image processing are developed in this
investigation. By use of these software, image and data
processing of escaping pictures of hydrogen bubbles can be dealt
with, avoids the complicated counting work of escaping pictures
of hydrogen bubbles can be dealt with, avoids the complicated
counting work of people. And dynamic escaping behaves of
hydrogen in welded zone of two kinds of alloyed steels 16Mn and
30CrMnSiA are studied by means of the further study of
micro-mechanism of hydrogen-induced cold cracking as well as
engineering practice.
Key words:
