For calculating thermal cycle of bond in weld joint analytically, the equation is very complex by the term of plate thickness. In case of weld joints with various shapes of groove it cannot be calculated. Then, F.D.M. of F.E.M. by computer are used for these cases, but these methods are not convenient. The authors proposed the approximate equations for estimating thermal cycle of butt weld joint considering the change of dimension of heat flow and law of similitude in geometrically similar specimens. These approximate equations have terms of plate thickness, angle of groove and heat input. Datas for making equations were calculated by F.D.M. Values estimated from approximate equations nearly corresponded to the experimental values obtained from arc welding with coated electrode.
