The use of thick or special materials in marine structures has been recently increased under the requirement of high operative efficiency. However many practical problems in the conventional welding of these materials are not always controlled. Electron beam welding process is expected to be hopeful because of its high power density (10^4-10^5 times in comparison with conventional arc welding). The purpose of the present investigation is to examine weldability of HY-90 steel and 9% Ni steel used in marine structures by electron beam welding and also to investigate the possibility of its application to the marine structures. Consequently, HY-90 steel and 9% Ni steel were welded nicely by electron beam and several several practical processes of the application to marine structures were proposed.
