Remote-controlled automatic welding method - uses programmed parameters corrected according to TV camera monitored bevelling and deposit

摘要

A parameter group (A) for the welding conditions which are not changed by the inner factors of the welding part and another parameter group (B) for the welding conditions which are changed by the factors are programmed. Welding is made determining the welding condition suitable to each position of welding with the signal. The parameter group (A) is kept in the programmed condition during the welding, and welding is made correcting the parameter group (B) according to the information about the bevelling and deposit metal which are obtained by a TV camera. The arc voltage, welding current, welding speed, filler wire filling speed, and weaving speed which are not necessary to be observed are set automatically with a program. The position of the top end of the electrode and the weaving width which are necessary to be observed are observed through a TV camera, so remote-controlled welding may be made.
