    摘要: A method of assembling an electron gun, which method permits welding of a number of welding points to be effected simply, in a short period of time and without causing mechanical distortion in welded parts and comprises the steps of; causing relative movement of electron gun parts to be welded together and the axes of a laser beam for welding and a light beam for positioning a welding point, these axes being in a predetermined positional relation to each other; causing the light beam for positioning to be incident on a part to be welded; detecting reflected light obtained when the light beam for positioning is reflected by a portion of the aformentioned part to be welded corresponding to a welding point; stopping the aforementioned relative movement according to the detection of the aforementioned reflected light; and exposing the aforementioned welding point to the laser beam for welding according to the detection of the reflected light so as to effect welding of parts to each other.
