摘要： PURPOSE:To make visible penetration beads correct and to prevent the production of porosities by measuring the electric current conducting through base metals to the outside when an electron beam penetrates through the base metal, and changing the welding conditions in accordance with this electric current. CONSTITUTION:An electron beam A from an electron gun 4 is driven into the front side groove 2a of the groove 2 of base metals 1, 1. In the normal case in which the beam penetrates to the rear side groove 2b and forms copying penetration beads correctly, the electric current value flowing in the earth line 6 of the base metals 1 is measured with an ammeter 5. On the other hand, when porosities are produced or the penetration beads are not correct welding, the melt flow changes and therefore the current value flowing in the line 6 differs from that during the correct welding. This current value is visually observed with the ammeter 5 or is fed back to the control system to change the beam output or the welding conditions such as welding speed properly, whereby the current value of the line 6 is corrected to the correct value.

摘要： PURPOSE:To enable diffusion joining even in super-heat-resistant alloys, by setting a pair of members to be joined butt to butt with a soft metal layer inserted in the middle, rotating one member with respect to the other member, and keeping the heated pressurized state for a specified period of time. CONSTITUTION:Soft metal layers 3, 3 of thin pieces of Ni, Cr or the like are formed on the surfaces of grooves 2, 2 of members 1, 1 to be joined (super-heat-resistant alloy). With one of the members 1, 1 secured, while rotating the other member at low speed so that the both joining surfaces on one side may be parallel, pressure is applied so that the soft metal layers 3, 3 may contact with each other, and at the same time the joining part is heated to high temperature by the rotary frictional heat. Thus, the members 1, 1 are joined together through the soft metal layer 3, then the rotation of the one member 1 is stopped. Next, under the specified joining temperature and pressure, the same state is maintained for 5 minutes to 14 hours to promote the diffusion between the soft metal layers and the members being joined, and a boundary layer 5 almost similar to the member being joined is formed in the joining part, and joining is completed.

摘要： PURPOSE:To prevent decomposition and fusion of carbides of the grain boundary in the heat affected zone likely to occur when welding, by carburizing the groove surface to increase the carbon concentration in the vicinity thereof. CONSTITUTION:Only the vicinity of groove faces 2, 2 of works 1, 1 is carburized to form carburized layer 3, 3 (the depth A of carburized layers should be preferably 2-3mm, for instance, in the case of Inconel 713C). Then, the joints of works 1, 1 are joined together through a weld zone 4 by electronic welding, and then heat treatment is given to diffuse the carbons remaining in the carburized layers 3, 3 into the works 1, 1 and weld zone 4 so as to make uniform the carbon distribution.

摘要： PURPOSE:To prevent the thermal distortion of low alloy cast and forged steel, etc. used for an internal gears and an internal gear hub, the lowering of the accuracy of the gears being accompanied by the thermal distortion, the reduction of the hardness of a quenched portion, etc., by decreasing welding heat input by adopting electronic beam welding. CONSTITUTION:In a planetary reduction gear that a connecting portio between an internal gears 22 and an internal gear hub 21 is a welding structure, a circular projection A is shaped to the outer circumference side of a butt portion of the internal gears 22 while a faucet projection C is formed to the inner circumference side of a butt portion of the internal gear hub 21, and both are fitted in a press-in or transition fit while the fitting portion B is joined by electronic beam welding. This device can attain the desired target, and can easily obtain necessary joint strength as compared to a bolt connecting sysbem and a gear connecting system in conventional devices while allowing the reduction of the number of parts.

摘要： PURPOSE:To prevent the generation of porosities and wormhole like beads in performing electron beam welding by changing the cross sectional shape of an electron beam from a circular shape to an elliptical shape at prescribed periods. CONSTITUTION:In electron beam welding, a deflection coil 2 for an electron beam 3 is provided in the lower part of a focusing coil 1 for the beam 3, and a transmitter 4 and an amplifier 5 are installed to the connection thereof so as to form Kapp's magnetic field when electricity is conducted to this coil 2. When the electrical circuit for forming the Kapp's magnetic field is held open, the cross sectional shape of the beam 3 is circular, and if the circuit s closed, the beam deforms to an elliptical shape. In this way, the cross sectional shape of the electron beam is changed periodically, by which the disturbance and pores in the flow of the molten metal in the molten pool in welding base metals are agitated and reheated, whereby the generation of porosites and wormhole beads is prevented.

摘要： PURPOSE: To control the copying of the groove on the rear side easily and adequately by providing a pair of interposing materials consisting of materials differing from base metals and of mutually different materials to the groove on the rear side of the base metals and detecting the intrinsic X-rays generating from the interposing materials.
CONSTITUTION: A pair of interposing materials 5, 6 are set near the groove 2b on the rear side of the groove 2 of base metals 1, and respectively different materials are used for these three. An X-ray detector 7 is disposed on the rear side of the base metals 1, and is so set that the X-rays detected by a slit 8 are sligned in one direction and are conducted to a crystal 9, and that the X-rays genetrating from the material 5 enters a counter tube 10 and the X-rays from the material 6 enters a counter tube 11. When an electron beam A is irradiated from an electron gun 4, it is irradiated to either of the materials 5, 6 when it is not correctly irradiated to the groove 2a, then the X-rays intrinsic to the materials 5, 6 are genetrated and are detected by either of the tubes 10, 11. According to the deflection of the beam A, bases 3 are operated to move the base metals 1, whereby the copying control is accomplished.

摘要： PURPOSE:To weld a base metal having a groove gap of even 2-6mm., with small thermal strain, by welding the I-shaped groove formed in part of welding surface of a base metal by electron beams, and radiating electron beams to the extremely small groove formed continuously to the I-shaped groove to build up welding. CONSTITUTION:The end faces of protrusions 3, 3 projecting in the axial direction, which are formed preliminarily, are set butt to butt in the central part of the welding surface 2 of base metals 1, 1 to form an extremely small gap 4 of about 2-6mm.. In thisf state, the materials 1, 1 are set opposedly to each other. By butting the end faces of the protrusions 3, 3, an I-shaped groove 5 having a groove gap of 0-0.1mm. is formed in the central part. Welding is then performed by radiating electron beams 6a to the groove 5. Then, the end part of a wire feeder 7 is inserted into the gap 4, and beams 6a are radiated to the wire 8 being fed successively to build up welding 10 consisting of plural layers 91, 92-9n while rotating the materials 1, 1, for example, in the direction of 5a, so that the materials 1, 1 may be completely welded.
