Abstract

PURPOSE:To achieve a constructional simplification of a shadow mask welder and to raise the efficiency of welding work on a shadow mask, by restricting the movement of the electrode of the welding head to only the horizontal direction. CONSTITUTION:A welding head 20 is actuated after the positioning of a frame 2 and mask 1 has been finished. During the feed of the frame 2 and mask 1, an electrode 21 of the welding head 20 is kept in its retracted position, namely, within a groove 12, but after the positioning of the frame 2 and mask 1, an air-cylinder 23 actuates in such way that the mask 1 is pressed at the inside thereof by the electrode 21 and welded to the frame 2. Upon the completion of the welding, the electrode 21 returns to its original position. Subsequently, the frame 2 is released by the actuation of the air-cylinder.
