Title:
溶接方法及び溶接接合体
Document Type and Number:
Japanese Patent JP7238437
Kind Code:
B2
Abstract:
To provide a technology which can adequately secure reliability of a welded part of a first type metal material and a second type metal material of different kinds from each other.SOLUTION: A first type metal material 11 is a metal material having higher embrittlement resistance after melting and solidification than a second type metal material 12. A welding method includes: a first process of scanning an irradiation position 31 of an energy beam 30 from a first position P1 to a second position P2 along a boundary part 10 and forming a linear melted and solidified part 41 along the boundary part 10; and a second process of scanning the irradiation position 31 of the energy beam 30 from the second position P2 to a third position P3 as a first side D1 position than the second position P2 when a side from a side of the second type metal material 12 to a side of the first type metal material 11 in a direction D intersecting with the boundary part 10 is the first side D1 after the first process, and finishing irradiation of the energy beam 30.SELECTED DRAWING: Figure 5
