Total oxygen content in weld metal is usually several times higher than in general rolled steel. Oxygen content which is soluble in matrix is extraordirary low, therefore almost oxygen exists in the form of non metallic inclusions. Attempts have been made to extract non-metallic inclusions to carbon film to be studied with on electron microscope. By the electron microscope the very minute non-metallic inclusions such as smaller than 1μ can be direct observed. The size, shape, constituents ahd other characteristics of non-metallic inclusions have been determined by means of electron diffraction method and direct observation. The author tried to obtain rather simple non-metallic inclusions and used single deoxidizer such as silicon, manganese, titanium, etc. The core wire, its carbon content is very low and its silicon and manganese contents is reduced to neglsible small, was used in this investigation.
