Title:
異材接合用溶加材及び異材溶接構造体の製造方法
Document Type and Number:
Japanese Patent JP5689492
Kind Code:
B2
Abstract:
Provided are a welding filler material for bonding different kind materials that improves joint strength and reduces cracks at the bonded part in different kind material bonding of an aluminum material or an aluminum alloy material and a steel material and has difficulty to break at the time of the wire drawing process, and a method for producing a different kind material welded structure. The welding filler material is formed by containing at least 1.0% by mass to 6.0% by mass of Si and 0.01% by mass to 0.30% by mass of Ti with a remainder being aluminum and inevitable impurities. Alternatively, the welding filler material is formed by filling a flux into a sheath material so that the filling rate is 2.0% by mass to 20.0% by mass relative to the mass of the whole wire, where the sheath material is formed of an aluminum alloy that contains at least 1.0% by mass to 6.0% by mass of Si and 0.01% by mass to 0.30% by mass of Ti with the remainder being aluminum and inevitable impurities. An aluminum material or an aluminum alloy material and a steel material are welded with each other using one of these welding filler materials.
