る突き合わせ溶接機を提供するものである。In practice, it is very often necessary to weld materials to be welded, such as rods or tubes made of different metals, such as aluminum and copper. In welding such dissimilar metal materials, it has been extremely difficult to perform good welding because the electrical resistance and melting temperature of each metal are different, so both materials to be welded do not melt uniformly. In addition, even if the metal materials are of the same type, for example, when welding materials with different cross-sectional areas, the temperature rise of each material will differ due to the difference in current density in each material, resulting in good welding. It was difficult to do so. On the other hand, the present invention aims to solve the problems of the prior art, and even when the materials to be welded to be mutually welded have different types, shapes, etc., the two materials can be welded together. To provide a butt welding machine that can perform good welding by matching the melting conditions of.

次に上記構成の作用効襲について説明する。A current flow path A including the secondary winding 21 of this transformer, the material to be welded 13 held between the electrodes of one electrode piece 5 of the electrode 1, and the electrode 11 of the other electrode piece 5 is defined. It is called the first circuit. When the material to be welded 13 is a material with high electrical resistance such as steel or stainless steel, each electrode piece 5, 5 of the electrode 1 may be constructed in the same manner as the electrode piece of the electrode 3. In other words, each electrode piece 5, 5
is formed only from a material with low electrical resistance such as copper. In this case, the material to be welded generates heat by itself due to the current flowing therein. Further, as shown in FIG. 3, power supply terminals 27, 27 are formed at both ends of the electrodes 11, 11 in the longitudinal direction of the electrode pieces 5, 5 of the electrode 1. Connect the power supply terminals 27, 27 at both ends of the
Alternatively, it is also possible to supply power in series. In this case, the current flows along the longitudinal direction of each electrode 11, 11, and the first circuit A does not include the object to be welded. The terminals of the secondary winding 23 of the transformer are connected to the electrode supports 9, 9 of each electrode piece 5, 5 of the electrode 1, and the other terminal is connected to the electrode piece 7, 7 of the electrode 3.
When the end faces of the welded materials 13 and 15 are butted against each other during welding, the one welded material 13 held between the electrodes 11 and 11 and the other welded material 15 are held together. A current flows through the path of the electrode 3. This flow path 5 is called a second circuit. Electrode 11,1 of each electrode piece of electrode 1
1 is further provided with a power supply terminal, it is also possible to directly supply power to the electrodes 11, 11 from the terminal of the secondary winding 23 of the transformer. Although the secondary windings 21 and 23 of the transformer are shown separately in the figure, they may actually be separate windings or may share one winding.
Next, the effects and effects of the above configuration will be explained.

なる被溶接材の突き合わせ溶接に好適なものである。First, the materials to be welded 13 and 15 are inserted between the electrode pieces of the electrodes 1 and 3, respectively, and a force-stretching device (not shown) is operated to clamp the materials. At this time, the end faces of the materials to be welded to be mutually welded are made to face each other between the electrodes 1 and 3, and are spaced apart from each other. Furthermore, among the materials to be welded, a material to be welded made of a material with a high melting temperature is held between the electrodes 1 and a material to be welded made of a material with a low melting temperature is held between the electrodes 3.
When the material to be welded 13 is pressed between the electrode pieces 5, 5, a current flows through the first circuit A. That is, from the secondary winding 21 of the transformer to the electrode 11 of one electrode piece 5. A current flows through the material to be welded 13 and the electrode 11 of the other electrode piece 5 . This current causes the electrodes 11, 11 made of a material with relatively high electrical resistance to generate heat. Furthermore, if the material to be welded 13 is a material with high electrical resistance, the heat generated by the material to be welded itself is also added. The materials to be welded 13, 13 are heated by this heat. Next, a butting pressurizing device (not shown) is activated to bring the electrodes 1 and 3 close together, and the end surfaces of the welded materials 13 and 15 are butted and pressurized. When the end surfaces of the materials to be welded 13 and 15 come into contact with each other, a current flows through the second circuit B. That is, current flows from the secondary winding 23 of the transformer through one electrode, the workpiece supported by that electrode, the other workpiece, and the electrodes that clamp the workpiece. This current melts and welds the abutting portions of the materials to be welded 13 and 15. Since the material to be welded 13 has been heated in advance as described above, the materials to be welded 13 and 15 are melted at the same time. The current flowing in the first circuit A is adjusted so that the current in the second circuit B quickly heats the material to be welded 13 to a temperature at which the material to be welded 15 melts at the same time as the material to be welded 15. When welding of the materials to be welded is completed, the pressure device is activated to release the electrodes 1 and 3, and then the butt pressure device is activated to release the electrodes 1 and 3.
are laterally spaced apart from each other and return to the work starting position to prepare for the next work. A second embodiment of the present invention is shown in FIGS. 4 and 5, and this embodiment is suitable for butt welding of welded materials having different cross-sectional sizes.

For example, to adjust the size of channel 1 or
It is also possible to insert a suitable current regulating device in either direction. In addition, when the material to be welded is a material with relatively high electrical resistance such as steel or stainless steel, the electrode pieces 5, 5 of the electrode 1 are replaced with the electrode pieces 7, 7 of the electrode 3, as in the first embodiment. Can I configure it the same way? Next, the operation of the above configuration will be explained.
