Abstract

PURPOSE:To avoid the effect of splash which takes place on welding by irradiating a specifically designated pattern of laser light divided into at least more than two in a non-circular form. CONSTITUTION:When oscillating the laser oscillator 10, the laser light 11 reflected at the reflecting mirror 12 is irradiated onto the welding points 17 and 18 concurrently in the form of an oval spot by the action of the dividing lens 13 to weld the grid electrode 4 and the convergence cup 5. In this case, the oval direction of the spot is directed toward the radial direction of the convergence gup 5, and its short diametrical direction is turned to directions out of the paths 1, 2, and 3.
