硬化肉盛用MIGアーク溶接ワイヤおよび硬化肉盛用MIGアーク溶接方法
Document Type and Number:
Japanese Patent JP5022428
Kind Code:
B2
Abstract:
A wire is adopted to hardfacing MIG-arc welding using a pure argon gas as a shielding gas. The wire is a flux-cored wire prepared through drawing a steel hoop or steel pipe as a sheath in which a flux is filled. The flux contains, based on the total mass of the wire, C: 0.12 to 5.00 percent by mass, Si: 0.50 to 3.00 percent by mass, Mn: 0.30 to 20.00 percent by mass, P: 0.050 percent by mass or less, S: 0.050 percent by mass or less, and at least one of TiO 2 , ZrO 2 , and Al 2 O 3 (TiO 2 +ZrO 2 +Al 2 O 3 ) in a total content of 0.10 to 1.20 percent by mass and has a total content of silicon and manganese (Si+Mn) of 1.20 percent by mass or more. The wire has a ratio of the total mass of the flux to the mass of the wire of 5 to 30 percent by mass.
