Welded structure and manufacturing method thereof

摘要

A welded structure may include a first member having a spherical surface part, and a second member which is formed in a plate shape. A part of an end face of the second member before laser welding is performed is formed to be a contact end face having a contact part with which a part of the spherical surface part is contacted. The second member is formed with a joining part including the contact end face and the joining part is joined to the spherical surface part by laser welding. At least before laser welding is performed, a plate thickness of the joining part is thinner than a plate thickness of a portion of the second member except the joining part and the spherical surface part of the first member and the end part of the second member are joined to each other by laser welding.

1. A welded structure comprising:
a first member having a spherical surface part which is formed in a spherical surface shape; and a second member which is formed in a plate shape; wherein a part of an end face of the second member before laser welding is performed is formed to be a contact end face having a contact part with which a part of the spherical surface part is contacted; wherein the second member is formed with a joining part including the contact end face, the joining part being joined to the spherical surface part by laser welding; wherein at least before laser welding is performed, a plate thickness of the joining part is thinner than a plate thickness of a portion of the second member except the joining part; and wherein the spherical surface part of the first member and the end part of the second member are joined to each other by laser welding.
