Abstract: A cathode ray tube includes a faceplate panel with a plurality of electrode support studs distributed about and attached to the panel. A color selection electrode having a plurality of support springs is disposed within the panel. Each of the support springs comprises a strap-like element having a proximal end secured to the electrode and a distal end spaced from the electrode. A washer-like element is located between the panel and the distal end of at least one of the strap-like elements. The washer-like element has a frustoconically-shaped portion with an aperture therein for snugly receiving one of the studs. The base portion of the washer-like element is substantially flat and is permanently secured to the strap-like element near its distal end.

Abstract: A welding apparatus for welding a washer to a frame retaining spring while the washer and the spring are in engagement with a stud affixed to the sidewall of a kinescope panel. A welding head is suspended by an articulated joint and by flexible straps whereby the welding head is free to pivot and to flex to assure engagement with the parts to be welded when the spring is out of alignment with the welding head.
