Abstract

1,102,437. Welding by pressure. STANDARD TELEPHONES & CABLES Ltd. 10 June, 1966, No. 25958/66. Heading B3R. [Also in Division H1] A sealed enclosure for an electrical component such as a miniature crystal includes a metallic member supporting the component and having a flat rim and a metallic cap having a flat surface and a groove between its centre and its periphery, the flat rim and the flat surface are cold welded together and the cap is dimpled due to flow of metal during cold welding. A base 2 of nickel-iron alloy has metal to glass seals 3 through which pass leads 4 carrying a miniature piezo-electric crystal and the base is brazed in a copper eyelet 5 having a flat rim 6. A copper cap 7 having a circular groove between its centre and periphery is placed over the eyelet and the rims on the cap and eyelet are cold welded by an annular lower tool which supports the eyelet and an annular upper tool having a partially recessed spigot which controls the extent of the dimpling as metal flows inwardly away from the weld. Metal which flows outwardly is cropped.
