Abstract
A welding equipment that forms an end part includes a vacuum chamber; a holding member that is installed in the vacuum chamber and that holds the end part in which a welding groove is formed by placing a half cell, an end plate, and a beam pipe next to each other; a window that is installed in a top-end surface portion of the vacuum chamber, which intersects with an axial center of the end part, and that forms a portion thereof; a laser radiating head that is installed outside the vacuum chamber and that radiates a laser beam into an internal space of the end part through the window; and a mirror member that is installed in the internal space of the end part and that adjusts a reflected laser beam, formed by reflecting the laser beam, so as to be oriented perpendicular to the welding groove.
