Description of the Related Art In a vehicle body assembly line, a plurality of vehicle body components are welded to each other at a plurality of temporary attachment points necessary for maintaining the vehicle body shape, and after assembling the vehicle body, the strength of the vehicle body is secured. Has been subjected to additional welding. Then, when welding the temporarily attached portion, a plurality of vehicle body components are mutually positioned by a positioning member provided on a welding jig arranged on both sides of the assembly station, and in this state, a plurality of welding guns mounted on the welding jig are used. Welding of a plurality of temporary attachment points is performed.

５７７号公報、特公平３−１３１１５号公報参照）。Conventionally, a welding transformer connected to a welding gun mounted on the welding jig is installed, and power is supplied directly from the welding transformer to the welding gun. However, this increases the size of the welding jig. There is a problem to do. Therefore, the welding gun mounted on the welding jig is composed of an indirect power feeding gun with an extended power supply terminal, and this power supply terminal is clamped by a welding gun such as a portable type to supply power to the welding gun mounted on the welding jig. There is also known a method for performing the above-described operations (Japanese Patent Laid-Open No. 63-63).
577, Japanese Patent Publication No. 3-13115).

In this case, however, it is necessary to press a plurality of temporarily attached portions in order to perform welding. As a result, distortion occurs at the time of welding of the temporarily attached portion at the front of the welding order, causing a displacement of components at the later temporarily attached portion, making it difficult to secure the shape accuracy of the vehicle body. In view of the above, an object of the present invention is to reduce the equipment cost and to assemble a vehicle body with high accuracy.

Power is supplied to the first welding gun from the second welding gun, and it is not necessary to install a welding transformer in the welding jig. This makes it possible to reduce the size and weight of the welding jig and reduce equipment costs. In addition, since the first welding gun is used to weld some of the temporarily attached portions and then the second welding gun is used to weld the remaining temporarily attached portions, misalignment of parts during welding by the second welding gun may be caused by the first welding gun. Therefore, it is prevented by the temporary attachment portion welded, and the shape accuracy of the vehicle body is secured.

Temporarily attached portions (the locations marked with X in FIG. 5) are sequentially welded. In this case, since it is not possible to simultaneously clamp all the temporary attachment portions that the second welding gun 12 is in charge of, parts may be displaced at the subsequent temporary attachment portion when welding the preceding temporary attachment portion in the welding order. However, since the main temporary attachment portion is welded in advance by the first welding gun 9 as described above, displacement of parts is prevented, and the automobile body W is assembled with high accuracy. In addition, the first welding gun 9 may be opened when welding the temporarily attached portion by the second welding gun 12. However, in order to further improve the function of preventing misalignment of parts, the welding of the temporarily attached portion by the second welding gun 12 is completed. It is desirable to open the first welding gun 9 later. Further, according to this, when the first welding gun 9 is opened, the temporarily attached portion is sufficiently cooled and solidified, and when the gun is opened, the unsolidified metal is pulled up in a whisker shape while adhering to the gun electrode and solidified as it is, so-called. The occurrence of welding defects such as pickup can also be prevented.

However, the welding jig 3 does not need to be provided with a welding transformer for the first welding gun 9 and the first Since the welding gun 9 is not used to weld all the temporary attachment points, the number of the first welding guns 9 to be mounted can be reduced. As a result, the welding jig 3 can be reduced in size and weight, and replacement work can be facilitated. Costs can also be reduced.
