抄録

On the tensile test specimens of ilmenite type arc welding electrodes for mild steele (4 and 5mm dia) which were tested in accordance with JIS G 3524 in the Report 1 authors further analysed statistically distribution of fisheyes and correlation between fisheye and tensile properties. The results are summarized:<BR>1. If the size of fisheye is indicated by the diameter which is derived from the total area of all fisheyes, found in a fractured surface of test specimen, distribution of fisheyes and correlation between size of fisheye and tensile properties can be fairly well represented.<BR>2. In very few electrodes, fisheyes are absent, and there is a slight stronger tendency for 5mm dla to develop fisheyes than 4mm dia.<BR>3. There is an evident negative correlation between fisheye and elongation or reduction of area, but a less evident such relation, between fisheye and tensile strength or yield point. These correlations clearly indicated especially with contour ellipses.
