PURPOSE: To enable attachment of parts for nonsplash in welding and besides, improve the accuracy in attachment and assembling by performing selection attachment of the elastic support member of the color cathode-ray tube of a color by TIG welding.

CONSTITUTION: An elastic support member 6b for supporting a color cathode-ray tube color selection mechanism 4b on a glass board 10 is attached by TIG welding (15: rod electrode) to a color selection mechanism frame 5b or a support member 7 attached to this frame 5b. According to this method, an electrode and works (spring and spring holder) are in noncontact condition, and besides since they are welded in inert gas atmosphere, splash (spark) does not occur, consequently no dust by splash may occur.
