THE APL RESISTANCE WELDER.
Abstract
In order to improve the reliability of welds used in satellite construction, a new welding machine has been developed. This welding machine consists of a set of storage batteries to supply current, a bank of transistor switches to regulate the magnitude and duration of the current, and a commercial welding head. The new welder produces: a pulse whose current and duration can be independently controlled to a high degree of accuracy; a pulse whose current remains very close to its predetermined value regardless of changes in resistance in the weld being made; a pulse which is constant from day-to-day and from machine-to-machine.
