The memory system of dual channel A/D automatic acquisition is studied in this paper. Using transceivers and gating controllers, the data bus and address bus of RAM are respectively controlled.

In this research works, the authors, using the optical welding robot, have controlled arc for improving the welding quality. The control system consists of TV-camera, micro-computer and image memory.

The whole system is controlled by a special computer system provided with back-up memory, key-board, micro-printer and led display.
