摘要： PURPOSE:To maintain welding conditions automatically constant by detecting the amplitude of the oscillations generated during welding in a disc-like electrode pair which is held in press contact with materials to be welded, to detect welding condition and controlling welding conditions automatically. CONSTITUTION:During progression of welding, the relative displacement (h) of upper, lower electrodes 1a, 1b is monitored at all times with a displacement sensor 7, and the amplitude Aa of the electrode 1a is detected. The amplitude varies with the change in the size of a molten layer. The limit amplitude reference values on the over-forming side of the layer 31 and the under-forming side of the layer 32 are defined as A1, A2 respectively. Said amplitude Aa is applied via an arithmetic device 8 to a comparator 9, by which the Aa is compared with the A1 and the A2 and when the same deviates from the range of the reference values, the number of revolutions of a motor 11 is controlled, by which the welding speed is controlled automatically so as to keep the amplitude Aa within the specified range. It is equally well to control welding current automatically so as to keep the Aa within the specified range. Thus, the welding conditions is automatically maintained satisfactorily.

摘要： PURPOSE:To make the temp. distributions of joining interface uniform and to prevent the generation of joining defect parts like cavities in the case of joining parts to be joined to the end parts of base plates by superposing the free end parts of both base plates in such a way as to extend in mutually symmetrical directions. CONSTITUTION:The free end part sides of a pair of base plates 4a, 4b of prescribed length are superposed on each other, and the longitudinal directions thereof are extended mutually symmetrically. Parts 3a, 3b to be joined are sandwiched between the plates 4a, 4b, and upper, lower electrodes 1, 2 via brazing filler metals 5a, 5b. When prescribed voltage is applied to the electrodes 1, 2, the heat on the respective free end part sides of the plates 4a, 4b flows toward the longitudinal direction of the plates 4a, 4b which are in superposition and contact on and with each other without saturation, thus the temp. difference from the point A to B and from the point A' to B' at the respective joining interfaces is extremely small, and the drooping of the brazing filler metal layers and the generation of joining defects like cavities are eliminated.

摘要： PURPOSE:To prevent the excessive melting of thin-films formed onto each member stably by shaping solder projections to the thin-films and preferentially heating only the noses of the projections when the each solder projection is contacted. CONSTITUTION:The solder projections 3a, 3b are formed previously to each of the first and second members to be joined 1a, 1b through the conductive thin- films 2a, 2b for shaping the projections. The solder projections 3a, 3b are contacted and reflowing-bonded, but respective solder projection 3a, 3b is heated so that the temperature of the nose sections is higher than the base sections and joined at that time. The heating method is that microwaves 5 are irradiated under a condition that there are comparatively much flux 4 at the contacting sections of several solder projection 3a, 3b. Accordingly, the flux 4 is heated preferentially because the dielectric loss to the microwaves 5 of the first and second members to be joined 1a, 1b, the thin-films 2a, 2b and the solder projections 3a, 3b is higher than that of the flux 4.

摘要： PURPOSE:To obtain a soldering device which is contrived so that sticking of the solder to the soldering iron is prevented and a good banked part of solder is formed, by heating the top part and its vicinity of soldering iron with electric current, when the soldering iron is pulled up at the time of completion of soldering work. CONSTITUTION:When soldering work is performed with soldering iron 1, the temperature of molten solder in the vicinity of top part of soldering iron 1 is preferentially raised by supplying electric current between soldering iron 1 and molten solder 5 from exclusive power source 8 in the course where soldering iron is pulled up when the soldering work is completed. In this way, the sticking of molten solder 5 to the end of soldering iron is prevented, and the stuck amount and banked shape of solder on the joining part can be maintained at a constant state. The above- mentioned heating by electric current may be made at need in either way, whether molten solder 5 in the vicinity of top part of soldering iron 1 is heated by electric current from exclusive power source 8 or the top part of soldering iron 1 is heated by electric current from exclusive power source 8 through projected part 11.

摘要： PURPOSE:To high-efficiently manufacture a short pipe with high quality, by welding butted two edges of a long size sheet material after being continuously bent into a cylindrical shape, by flattening this welded cylindrical pipe by a grooved roller, by shearing this flattened welded pipe into a specified length, and by expanding this short flat pipe to finish the purposed short pipe. CONSTITUTION:A pipe-forming long sheet material 1 such as a hoop, etc., is fed to the rotating squeeze rollers 6 and is laterally bent so as to butt both of sheet edges, which are continuously welded by the welding torch 2; hereby, a long sized, cylindrically formed, and welded pipe is continuously fed forward. Next, this welded pipe is continuously flat pressed by a grooved roller 12 to form a continuous, flat and welded pipe 13 which is then sheared by the shear blade 14 into a specified length. This short flat pipe 15 is expanded by driving an expanding zig 16 into the pipe 15; hereby, the short pipe 17 of specified size is obtained.

摘要： PURPOSE:To enable the sound brazing free from brazing defects such as voids, etc. to be performed by coating the undercoating material for brazing in the gap between the two members to be brazed which are bonded face to face, not over the entire surface. CONSTITUTION:Undercoating material 3 for brazing is coated in the central part of the gap faces of the two materials to be brazed 1, 2 which are bonded face to face except at least two opposing side end parts D. Brazing material 4 is supplied from one end part arrow A other than the side end part D and is spread along the undercoating material 3. Next, the coating material 3 for brazing is coated to the side end part D like the arrow E and the brazing material 4 is supplied like the arrow F, then brazing free from voids is completed. Here, the width from the end part of the side end part D is preferably within the range of 1-7mm.
