@article{oai:kitami-it.repo.nii.ac.jp:00006968, author = {棟, 徹夫 and 二俣, 正美}, issue = {2}, journal = {北見工業大学研究報告}, month = {Jun}, note = {application/pdf, Continuing the previous report(N0.1),we want to report here the results of some experiments on the variation of the maximum arc length under various blowing directions and the influence of the wind to the vaporized coating of electrodes.   An outline of the results will be described below.   (1)The maximum arc length is affected remarkably by the coating of electrode. The arc length of an ilumenite electrode is longer than that of a low-hydrogen electrode. It is observed that the vaporized coating, i.e.gas molecules, is more effective on striking the arc than the vaporized core metal and moreover the former depends strongly on t he winds' conditions.   (2)The maximum arc length is affected by the blowing directions. In the opposite blowing it is going to be the shortest and in the backward blowing, inclined at 45°,it is going to be the longest.   (3)The relation of L(θ)/L(π/2) and θ or the variation of the arc angle is independent of the kind of electrode and the blowing direction.   (4)The arc voltage at a moment of arc-vanishing depends on the blowing direction but the current is not so much affected.   (5)These results suggest that the interaction of the wind and the gas ionic flow of the coating will be a subject for a next study.}, pages = {211--224}, title = {溶接アークの最大長さにおよぼす風向風速の影響(第2報)}, volume = {3}, year = {1972} }
