Study on automatic welding of pipe, (1)

In a nuclear power plant, a large number of pipes must be set in very complex and narrow places. A remote control pipe welding equipment is developed, in order to solve difficulty of welding in such a narrow place. Characteristics of this equipment are summarized as follows. (1) All welding sequences are controlled by a mini-computer. (2) From the information displayed on the screen of control panel, which inculdes a TV monitor, the operator can evaluate results of welding, torch positioning and the groove shape. (3) The operating panel includes a keyboard which is used for parameter input and for communication with the welding equipment to make necessary adjustment. (author)
