LASER WELDED SHAPE STEEL MADE OF STAINLESS STEEL EXCELLENT IN CORROSION RESISTANCE AND GLARE-PROOFNESS, AND MANUFACTURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a laser welded shape steel made of a stainless steel not having a temper color on the surface, and excellent in glare-proofness, concerning a laser welded shape steel having a T-shaped joint part.;SOLUTION: A laser welded shape steel made of a stainless steel, which is a welded shape steel in which a T-shaped laser welded joint part is formed with a web member and a flange material, and which is excellent in glare-proofness is manufactured by adjusting 60-degree glossiness of a surface to be 75 or lower by immersing the welded shape steel after being welded into acid solution, by using a laser weld method for irradiating a laser beam as a weld method when welding the web member and the flange material.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
