ＣＯ２プラグ溶接に先立ち制振鋼板にアークスポット溶
接を施す方法は開示されていない。Normally, when repairing, the defective part is removed and reassembled by welding, but even if the part was spot welded during regular assembly, the spot gun cannot access it during repair due to the plate assembly, so spot welding is performed. This is often not possible and it is necessary to attach using other welding methods, for example plug welding. An example of this can be seen when a damping steel plate is attached to a steel plate member such as an automobile body from below, a plug hole is provided in the steel plate member, and plug welding is performed from the upper side to weld the damping steel plate to the steel plate member. It will be done. In addition, arc welding and plug welding between vibration damping steel plates and steel plate members are

However, as in the present invention described below,
There is no disclosure of a method for performing arc spot welding on damping steel plates prior to CO2 plug welding.

として働がないので、溶接強度（剪断強度）が著しく低
下するという問題があった。However, when a damping steel plate consisting of a laminated plate with resin sandwiched between the upper and lower plates is attached to a steel plate member by ordinary CO2 plug arc welding, as shown in Figure 3, the upper plate of damping steel plate 1 is attached to steel plate 2. Since the side panels 1a are not welded and the lower plate 1b does not function as a strength member, there is a problem in that the welding strength (shear strength) is significantly reduced.

問題がある。Alternatively, as shown in Fig. 4, there is a method of attaching the damping steel upper plate 1a in the part corresponding to the plug hole 3 and performing plug arc welding, but it takes a lot of man-hours to attach the upper plate 1a. However, the resin layer IC is exposed to the inner surface of the plug hole 3 when the resin layer IC bends, so that there is a problem that organic gas blows out from the resin layer IC during CO2 welding, which has a negative effect on the CO2 plug welding.

板との溶接方法。According to the present invention, the above problems are solved or alleviated by the following method of welding with a damping steel plate. In other words, when performing plug welding between a damping steel plate with a resin sandwiched between the upper and lower plates and a steel plate located above it during repairs, etc., arc spot welding is first applied to the damping steel plate using the plug holes in the steel plate. The upper and lower plates of the vibration-damping steel plate are fused together, and then plug arc welding is performed between the steel plate and the upper plate of the vibration-damping steel plate to fill the plug hole and weld the steel plate and the upper plate of the vibration-damping steel plate. A unique method of welding with vibration-damping steel plates.

よるＣＯ□プラグ溶接への悪影響もない。In the method of the present invention, since the steel plate has a plug hole, the vibration damping steel plate is first subjected to arc spot welding using the plug hole. As a result, the upper and lower plates of the vibration-damping steel plate are integrated by arc spot welding nuggets at or near the portion where plug welding is to be performed next. Plug welding is then performed between the vibration-damping steel plate and the steel plate in which the upper and lower plates are integrated, but when the steel plate is welded to the upper plate of the vibration-damping steel plate, it is controlled via the nugget created by spot welding. It is also connected to the lower plate of the swing steel plate, and the welding strength is the same as when properly assembled (spot)? I
The contact strength is improved to the same extent as the contact strength. Furthermore, since the intermediate resin layer is not exposed, there is no adverse effect on CO□ plug welding due to the ejection of organic gas from the intermediate resin layer.
