THROUGH DIAPHRAGM WELD JOINT STEEL PIPE COLUMN, AND MANUFACTURING METHOD OF THROUGH DIAPHRAGM WELD JOINT STEEL PIPE COLUMN
PROBLEM TO BE SOLVED: To provide a through diaphragm weld joint steel pipe column not generating breakage of a weld metal prior to a base metal, even when using partial penetration welding to a single bevel groove weld joint.SOLUTION: Assuming that a groove angle of a single bevel groove of a weld zone of partial penetration welding is α(°), a plate thickness of a steel pipe provided with a single bevel groove is t(mm), a distance from the surface to the deepest part of the steel pipe in a weld metal is t'(mm), a weld reinforcement height is e(mm), a tensile strength of the weld metal isσ(N/mm), and a tensile strength of the steel pipe isσ(N/mm), these items satisfy a prescribed relation.SELECTED DRAWING: Figure 5
【課題】レ形開先溶接継手に部分溶け込み溶接を用いた場合でも、母材よりも先に溶接金属の破壊を生じさせない通しダイヤフラム溶接継手鋼管柱を提供する。【解決手段】部分溶け込み溶接部のレ形開先の開先角度をα（°）、レ形開先が設けられた鋼管の板厚をｔ（ｍｍ）、溶接金属のうち鋼管の表面から最深部までの距離をｔ’（ｍｍ）、余盛り高さをｅ（ｍｍ）、溶接金属の引張強さをＷＭσｕ（Ｎ／ｍｍ２）、及び鋼管の引張強さをＢＭσｕ（Ｎ／ｍｍ２）としたときこれらが所定の関係を満たす。【選択図】図５
