ULTRASONIC WELDING PROCESS AND EQUIPMENT FOR CONSTRUCTION OF ELECTRON-TUBE MOUNTS

摘要

Fabrication of the sample lot of 100 type 6080WB electron tubes was completed up to the last step in the assembly sequence. The last step could not be carried out because of a part change made by Tung-Sol since this effort was initiated. A method of adapting equipment and procedures to the current production part is being sought.nElectrical tests showed that most of the tubes in the sample lot had short circuits. The cause was found to be incorrect assembly prior to welding, not faulty welded joints. Appropriately modified inspection procedures will be used in fabricating a second sample lot.
