Description of the invention (Technical field to which the invention belongs) The present invention relates to a welding method and device suitable for arc welding or friction stir welding (Friction stir welding). (Prior art) Welding of large structures such as the body of a railway vehicle is performed by crimping both sides of the weld line with a crimping member. The pressurizing mechanism of the crimping member includes a lock bolt, an air cylinder, and a method of blowing high-pressure air into a wind pipe. These situations are described in the following documents. "Modern fusion technology" Volume 36 "is a brief introduction of automatic semi-automatic fusion. T I G fusion (translated name)" January 23, Showa 55, pp. 248 ~ 249. Also known as friction stir welding, workers are joined using a rotating joining tool.

Description of the invention Ge). When copying, use the honing machine to delete it. Since the above-mentioned welding is necessary, a wide working place and a large number of workers are required. In order to prevent the workpiece from being heated, expanded and deformed by the arc heat of welding, there is a butt difference in the groove (butt joint). Welding the workpiece with a crimping member is limited to the east and then welded (see the above document). . Therefore, when the workpiece is large, it becomes a very large-scale equipment and requires a large amount of equipment cost. Strain will also occur due to the heat of fusion. When the amount of strain exceeds the allowable amount, the correction of the strain will be implemented in the later process. The object of the present invention is to make it possible to perform welding at a low cost. (Means for Solving the Problem) The above-mentioned object can be achieved by substantially simultaneously performing honing, welding, and cutting of the superfluous beads that are welded.

The detector 50 irradiates the laser light to the groove and takes a picture of it with a CCD camera, so that the position of the welding torch 55 and the groove is often automatically tracked at a certain distance. The crimping device 60, 8 0, is The workpiece 1.0 is crimped to the back support 15 (pressurized). The crimping device 60 is used to prevent the workpiece 10 from expanding and deforming due to the heating of the arc of the welding torch 55, which causes the groove to have a butt gap. The pressure of the crimping devices 60 and 80 is achieved by air cylinders 6 1 and 81. The contact of the workpiece 10 is performed by the rollers 6 2 and 8 2 of the crimping device 60 and 80. The crimping effect of the workpiece is closer to the fusion The larger the melting pool is, but when the roller is too close to the welding pool, the rollers 6 2 and 8 2 will be overheated by the high temperature of the arc for a short period of time, so the cooling mechanism of the rollers 6 2 and 8 2 is provided. The roller 6 2 of 60 has a plurality of rollers, and all of the rollers 6 2, 6 2, ... are connected to each other by connecting plates 6 3 through pins 6 4 to form an infinite. Belt (endless belt). This endless belt is supported on the holder 6 5. The holder 6 5 is divided into two in the axial direction of the roller 62. A convex portion 6 5 a which contacts the inside of the endless belt is provided. The roller 6 2 is crimped to the workpiece 10 so that the upper surface of the lower roller 62 contacts the convex portion 65a.

Therefore, when compared with the crimping device 80, the roller 62 is cooled much more. The detector 50 detects the height position of the groove, and raises and lowers the column 32. In addition, the air cylinders 6 1 and 8 of the crimping device 60 and 80 and the cutting device 90 are raised and lowered at a predetermined pressure, and can be slightly moved up and down by the reaction force on the workpiece side. The cutting means of the cutting device 90 is an end mill, so that the cutting device can be made compact and inexpensive. In order to prevent excessive mechanical cutting by the cutting device 90, cutting. Only cut to a position slightly above the surface of the workpiece. After cutting through the weld joint 30, use the honing machine to work to the same side of the workpiece. If it is not necessary to cut by the cutting device 90, the end mill 9 2 does not need to be processed. The occurrence of welding strain can be alleviated by the removal of excess beads after welding. After completely cooling (room temperature) after welding to remove excess joint beads with a honing machine, compare with the amount of strain generated by an end mill cutter 9 2 to remove excess joint beads under high temperature after welding. Take the example of the workpiece in Figure 6 as an example. To show.
