摘要： PROBLEM TO BE SOLVED: To suppress a current flowing to a constituting transistor to a minimum limit. SOLUTION: Output terminals 3, 5 are an in-phase output terminal and an inverting output terminal of an amplifier of BTL (balanced transformerless) type. A resistor RO is an internal resistance of the amplifier of the BTL type as observed from the terminals 3, 5. V1 of a high level is input to an input terminal 1 to turn ON transistors Trs Q1, Q2, Q3, Q4 and Q5 to become a detecting mode. If a load resistor RL is not connected to the terminals 3, 5, a resistance as observed at the terminals 3, 5 is RO. Since this resistance is equal to a resistance R5, a collector current of the Q4 = a collector current of the Q5 is obtained. Since the collector current of the Tr Q5 > a current of a constant current I2 + a base current of Q6 is obtained, the Q6 is turned ON, and a signal of LOW level is present at a detecting terminal 7. Meanwhile, when the load RL is connected to the terminals 3, 5, the collector current of the Q5

The tip of a manipulator arm 22 is inserted into the set position in the water chamber end plate 3 from an inlet part of the manhole seat 3c by control of a simple NC device 25 and after this, a welding head 24 is rotated. A positioning state is photographed by a CCD camera 46 fitted on the upper part of a welding torch 45 and projected on a television monitor provided on a control panel 25. When misalignment is caused during welding, a torch right and left movement controller 43 is driven according to a signal from a profile sensor 52 and the welding torch 45 is allowed to follow the movement of the tube plate 2 and the water chamber end plate 3.

摘要： PURPOSE:To efficiently position a water chamber end plate, manhole seat and a feed water gate by providing constitution in such a way as clamping the water chamber end plate to an upper side table when work is applied to an inner side of the water chamber end plate, while clamping a manhole seat to a lower side table when work is applied to an inner side of the water chamber end plate, and allowing both the tables to be set up in horizontal and tilt- moving positions. CONSTITUTION:When an outer side of a water chamber end plate 1 is worked, it is clamped to an upper side table 5 and placed in a tilt position as necessary, and gas cutting, edge preparation and welding are executed thereon. When an inner side thereof is worked, the water chamber end plate 1 is lifted by a hydraulic cylinder 7 to a specified height and inverted, and its manhole seat is clamped and held to a lower side table 6. Under this condition, after the lower side table 6 is moved and tilted, gas cutting, edge preparation and welding are performed. At this time, the upper side table 5, being not in use, is left as horizontally placed with the hydraulic cylinder 7.

摘要： PURPOSE:To effectively perform the seal welding of a tube plate to a heat exchanger tube and the tube expanding work by operating cross slides and longitudinal slides by the prescribed moving quantity by a driving mechanism to operate based on a control signal given from a positioning unit. CONSTITUTION:In the application of the automatic welding, a welding head 55 is set up on first and second carriages 33 and 34. When a starting button is pushed, first and second cross slides move in the X axial direction by the determined moving quantity to stop and driving air is guided to an air cylinder 54 for feeding at a last place. A limit switch functions at a place where the welding head 55 mounted on the cylinder 54 moves in the Z axial direction and the tip of a position detection bar 56 comes into contact with the tube plate of a heat exchanger and it stops. A signal produced from the limit switch actuates a starting circuit of the welding head 55 at the same time to start the seal welding.
