The author has studied the welding phenomena between molten brass (4 : 6 Brass) and solid brasses having various concentrations of Zn, (0, 10, 20, 30, 40%) and has obtained the result similar to the case of welding between cast iron and steel. Namely, the degree of melting point of solid metal does not give any infiuences on welding or joining, therefore, regardless of the sorts of Cu alloys ; i. e, pure Cu or 4 : 6 brass, welding is completed under the same thermal condition. This will give us the suggestion that the welding phenomena is not occured due to the melting of solid surface but the intermetallic diffusion.
