Abstract: PURPOSE:To reduce a variation of a welding quantity, and to improve welding without being influenced by a groove variation or a spatter, etc. by constituting a titled device so that at least one layer of the second layer and thereafter detects a sectional area before welding of its layer by a non-contact sensor, and executing a prescribed buildup welding by a set welding condition. CONSTITUTION:After ending an uranami control welding guided by a non- contact sensor of the first layer in which the welding quantity is varied frequently, at least one layer of the second layer and thereafter derives a welding sectional area before welding 18 containing an excess metal quantity 19 by a non-contact sensor 2. By this storage, welding of the second layer and thereafter is limited to a prescribed quantity. By deriving a conventional initial groove section area, a variation of the welding quantity is reduced by comparing with the case when an automatic control welding is executed up to a prescribed quantity. As a matter of course, if the welding sectional area is derived by the sensor 2 at the time of welding of the last layer, its variation is further decreased. A variation of the groove by welding, and an influence by spatter, dust, etc. are also eliminated, and welding is executed satisfactorily.

IPC: G05F1/46
Filed: 1989-09-20
Abstract: PURPOSE:To prevent the drop of an output even in the case an excessive voltage is applied to a load side of an output rectifier from the outside by providing two voltage dividing resistance and a differential amplifier for comparing and outputting detected voltages obtained from these voltage dividing resistances on both ends of the output rectifier. CONSTITUTION:This circuit is provided with resistances 4a, 4b for detecting a voltage of a load terminal 11, resistances 3a, 3b for detecting a voltage of an output terminal 10 of a voltage converting part 1, and a differential amplifier 5 for comparing and outputting these detected voltages. When a higher voltage than a set voltage is applied to the load terminal 11 and a voltage of the inside of an output rectifier 2 becomes lower than that of the outside, the differential amplifier 5 executes opposite phase amplification and outputs a negative voltage. Accordingly, a rectifier 6 allows a current to flow in the forward direction, and a voltage to a switching control part 7 is lowered so as to become equal to a divided voltage of the resistances 3a, 3b. In such a way, even in the case an excessive voltage is applied to the load side of the output rectifier from the outside, it can be prevented that an output of a voltage converting part drops.
