• On the Method of Measurng Eccentricity and Bending in Nonferrous Electrode

抄録

A new method is described for measuring the eccentricity and the bending in nonferrous electrode by making use of the electromagnetic type instrument widely used to measure the eccentricity of steel core electrode and already reported in our previous paper (cf. J. Japan Welding Society 19, 203 (1950))<BR>The principle is to transform the changes in coating thickness and in core bending into the displacement of the iron plate attached to the instrument.<BR>By this method, the bending can be measured with great accuracy, but as for the eccentricity, errors frequently enter in its measurement owing to the effect of electrode bending. So we improved the measuring method to lessen the effect and succeeded in selecting electrodes of small eccentricity (less than 3%).<BR>We also measured the core bending by this method, finding out that the cause of eccentricity was sometimes attributable to the core bending.<BR>Advantages of this method are as follows:<BR>1) We can use the electro-magnetic type instrument.<BR>2) Operation is easier than the high frequency method presented in one of our papers (cf. Bul. Electrotech. Lab. 15, 144 (1951)).<BR>3) Measurement is done without stripping off electrode coating.
