Provided is a welding equipment that performs welding of an annular body from an inside thereof so as to be perpendicular to a welding groove, thus making it possible to enhance the weld quality. A welding equipment (1) that forms an end part (5) includes a vacuum chamber (23) in which a vacuum atmosphere can be established; a holding member (25) that is installed in the vacuum chamber (23) and that holds the end part (5) in which a welding groove is formed by placing a half cell (11), an end plate (17), and a beam pipe (19) next to each other; a window (29) that is installed in a top-end surface portion (27) of the vacuum chamber (23), which intersects with an axial center (0) of the end part (5), and that forms a portion thereof; a laser radiating head (35) that is installed outside the vacuum chamber (23) and that radiates a laser beam (33) into an internal space of the end part (5) through the window (29); and a mirror member (37) that is installed in the internal space of the end part (5) and that adjusts a reflected laser beam (55), formed by reflecting the laser beam (33), so as to be oriented in a direction perpendicular to the welding groove. |
