Abstract

The investigations of the characteristics of cold shut occurred in the electron beam weld metal have been done using aluminum and iron-based alloys. Consequently, three types of cold shuts occurred as follows. They are ; a-type occurred in the spikes, b-type occurred in connection with the porosity, c-type occurred in the vicinity of root except a-type and b-type. A lot of occurring numbers of cold shuts belonging to c-type in the weld metal of aluminum alloy was observed compared with the case in the iron-based alloy. It was recognized that cold shut tends to exist in the vicinity of strong spike and this condition corresponded well with the occurring zone of R-porosity. It was known that the high pressure vapor element included in the base metal segregated in the cold shut zone unlike ripple line and its metallurgical combination was defective.
