| 耐候性鋼板用溶接材料について On Welding Materials for Atmospheric Corrosion Resisting Steel Plates 坪井 潤一郎(Junichiro Tsuboi) 杉江 英司(Eiji Sugie) |
| 要旨 ： 耐候性鋼板用の溶接材料の開発を目的として，溶接部の耐候性をその電極電位の測定と大気暴露試験で判定し，さらに溶接材料の機械的性質を試験してつぎのことを確認した。1)適当量のCu，Ni，Crなどを含んだ溶接金属は大気暴露により，母材耐候性鋼板とほぼ同時の耐候性を示す。2)開発した耐候性鋼板用の被覆アーク溶接棒とサブマージアーク溶接材料はすぐれた機械性能をもち，実際構造物に供しうる。 |
| Synopsis : For the purpose of developing welding materials specially suited for welding the atmospheric corrosion resisting steel plates, the atmospheric corrosion resistance of the weld part was tested by measuring its electrode potential and exposing it to atmospheric corrosion, and also the mechanical properties of welding materials were tested. The results obtained were as follows; (1) The atmospheric corrosion test showed that the weld metal containing an adequate amount of Cu, Ni and Cr had an anti-corrosive property nearly equal to that of the mother plate of atmospheric corrosion resisting steel. (2) It was proved that the coated electrodes and the submerged-arc wires and fluxes designed for use on the atmospheric corrosion resisting steels, possessed excellent mechanical properties and that they could well be put to practical constructional uses. |
