Abstract
A butt position detecting method for a weld joint, when an arrangement direction of a first member and a second member is defined as a first direction, and a direction that is perpendicular to the first direction is defined as a second direction, the first member has a corner portion and a chamfer portion, and a two-dimensional displacement sensor is arranged at a position offset from the butt portion toward the first member side in the first direction, and such that an angle θs at which the second direction and an optical axis direction of irradiation light of the two-dimensional displacement sensor intersect with each other and an angle θa at which the second direction and a formation direction of the chamfer portion of the first member intersect with each other satisfy a condition expression: 0°<θs<θa.
