摘要： PROBLEM TO BE SOLVED: To prevent blown-out filaments by providing a heating voltage correction means for controlling the output of a filament power supply for filament voltage generation and a pulse power supply for pulse voltage generation and correcting each voltage balance within a specified range. SOLUTION: A cathode heating monitor device 44 judges the voltage balance between a filament voltage 30 and a pulse voltage 32 and outputs a voltage balance correction signal 45 to a cathode heating auto correction circuit 41 if the voltage balance exceeds the specified range. The cathode heating auto correction circuit 41, when the voltage balance correction signal 45 is input, controls an auxiliary power supply 27 so that the voltage balance between the filament voltage 30 and the pulse voltage 32 is within a specified range. Thereby heating power is maintained by the quantity according to consumption of the filament 24, and the voltage balance is within the specified range. When the voltage balance is normal, an indicator 52 is lit, and if the voltage balance cannot be controlled within the specified range the error signal is output to an alert circuit 53, and sudden faults are pre-inhibited.

摘要： PURPOSE:To prevent the degradation in the sensitivity of an X-ray sensor which detects the X-ray radiated from the position where an electron beam is irradiated without requiring specific parts and to effectively utilize the space in a welding chamber by providing the X-ray sensor in an electron gun for scanning the electron beam. CONSTITUTION:The X-ray sensor 7 is installed in the electronic gun 4. Namely, the X-ray sensor 7 is mounted in the part deeper than a cylinder 10 provided on the electron beam exit side of the electronic gun 4. The cylinder 10 limits the angle range where metal vapor can intrude as far as possible to suppress the amt. of the metal vapor to be intruded to the electron gun 4 body to the permissible amt. or below. The cylinder 10 is applied in this way to the prevention of the metal vapor to the X-ray sensor 7 as well, by which the inside of the welding chamber 1 is effectively utilized without having the need for separately providing the intricate metal sticking preventive mechanism requiring a large space and the detecting sensitivity of the weld line position is always well maintained.

摘要： PURPOSE:To improve a working accuracy and to shorten a working time by adding a high speed deflecting function to the deflecting function of an electron beam and performing the time share of a beam deflecting pattern as well as multi-beading one beam. CONSTITUTION:A high speed deflecting function is given with its adding to the deflecting function of the electron beam emitted from an electron gun 1 and the deflecting pattern of an electron beam 4 is optionally time-shared as well. Namely the electron beam 4 is made a multi beading by its deflection via a deflecting coil 3 and in case of forming a welding bead on a work 5, a beam deflecting pattern is subjected to time sharing by performing a center bead forming, etc., after forming the preceding bead at both sides. With this method the bead 4 having a smooth surface is formed by preventing an undercut forming. Consequently a microworking is enabled and a working distorsion is reduced as well. Namely the improvement in working accuracy and the shortening in working time are made possible.

摘要： PURPOSE: To perform locating of the weld points of a gratinglike welded structure accurately and quickly by using a rotary type transducer for a locating detector and combining this with a programmed control device.
CONSTITUTION: When one piece of cross bars 1AW1n of a gratinglike structure and a bearing bar 2AW2n are welded, a welding electrode 3 moves upward, and a disc brake device 11 and a rotary type transducer 21 move in order to detect the weld point of the next step. The pinion 21a of the transducer 21 revolves and its moving distance is detected with a moving distance detector of an automatic locating control device 23. The output thereof is compared with the welding process of a preprogrammed welding process control circuit 25 in a comparator 26, and when it goes equal to a target, a pitch feed driving device 10 is stopped. When the welding point of the next step is detected by this, the bearing bars 1AW1n are pulled up to the next point, and are welded to one unwelded piece out of the cross bars 1AW1n of the next step by resistance.

摘要： PURPOSE:To make stable flash butt welding of high quality possible by measuring the quantity of heat for flash charging to be applied to flash welding articles, and controlling flash voltage and the feed of a moving table in such a manner that this quantity of heat is kept constant. CONSTITUTION:The end face of an object 2 to be welded grasped by moving side electrodes 5, 6 under pressing force P is collided against the end face of an object 1 to be welded grasped by stationary side electrodes 3, 4, under pressing force P at a velocity V by the movement of a moving frame 8 directly coupled to a driving device 9. Flash is generated between the end faces of the objects 1, 2 by the flash current I2 generated by this collision. Further, the object 2 is repeatedly moved at the velocity V, so that the end faces of the objects 1, 2 are melted and welded by pressure. During this time, the quantity of heat for flash charging is detected 22, and is compared with the set reference quantity of heat having beforehand set 23 depending upon the quantities and sectional areas of the materials 1, 2. The result of the comparison thereof is fed back to the feed control for the moving table, and the speed of the frame 8 is so controlled by the device that the quantity of heat for flash charging and the reference quantity of heat are kept always equqal.
