PLATED WELD SHAPE STEEL AND MANUFACTURING METHOD OF PLATED WELD SHAPE STEEL
PROBLEM TO BE SOLVED: To provide a plated weld shape steel excellent in corrosion resistance of a part where a plated layer is missing and weldability at same time, and a manufacturing method of the plated weld shape steel.SOLUTION: A plated weld shape steel having a web consisting of a galvanized steel sheet, a flange consisting of the galvanized steel sheet and welded to the web, a weld bead positioned at a weld part of the web and the flange and a rust prevention film coating at least a part of the weld bead and containing a metal component, the metal component contains particles having a sacrificial anticorrosive action to iron, Irepresented by the following formula (1) is 0.5 to 30 μm, thickness of the rust prevention film is 30 to 130 μm. I(μm)=T (μm)×(100-M (mass%))/100, where T is thickness of the rust prevention film (μm) and M is content of the metal component in the rust prevention film (mass%).SELECTED DRAWING: Figure 2
【課題】めっき層が欠落している部位の耐食性を優れたものとしつつ、同時に溶接性に優れた、めっき溶接形鋼及びめっき溶接形鋼の製造方法を提供する。【解決手段】本発明に係るめっき溶接形鋼は、亜鉛系めっき鋼板よりなるウェブと、亜鉛系めっき鋼板よりなり、前記ウェブに溶接されたフランジと、前記ウェブと前記フランジとの溶接部位に位置する溶接ビードと、前記溶接ビードの少なくとも一部を被覆し、金属成分を含有する防錆膜と、を備え、金属成分は鉄に対して犠牲防食作用を有する粒子を含み、以下の式（１）で表されるＩｗは、０．５〜３０μｍであり、前記防錆膜の厚みは、３０〜１３０μｍである。Ｉｗ（μｍ）＝Ｔ（μｍ）×（１００−Ｍ（質量％））／１００ ・・・ （１）ただし、式（１）中、Ｔは、前記防錆膜の厚さ（μｍ）であり、Ｍは、前記防錆膜中の前記金属成分の含有量（質量％）である。【選択図】図２
