These are, of course, not used as they are, but are processed into various shapes, joined by welding, bonding, or the like to form molded products, and after various subsequent processes, are used for final use.

ることも知られている。When two or more galvanized steel sheets are stacked and laser-welded, zinc vapor is rapidly generated between the steel sheets due to the low boiling point of zinc, which blows away molten metal and forms pits and blow holes. It is well known that good appearance and strength cannot be obtained. On the contrary,
It is well known that good welding is possible by forming an appropriate gap between steel plates. It is also known that good welding is possible even by peeling and welding a layer containing zinc in a welded portion.

According to Japanese Patent No. 27189, it is described that plastic processing is performed in advance on some of the steel plates that are overlapped. In addition, many methods have been disclosed for forming a gap by inserting another member between steel plates. For example, Japanese Unexamined Patent Publication No.

明白である。However, a common problem in the above-mentioned methods is that a problem arises in securing the corrosion resistance that should be maintained. Zinc or zinc-based alloy plating is used for the part because corrosion resistance is required. However, if a gap is formed to enable laser welding, water, which is the most important corrosion factor, is likely to enter, and the corrosion resistance at this portion is greatly reduced. Also, it is obvious that the method of stripping the plating layer obviously eliminates the required plating amount.

FIG. 1 is a perspective view showing an image in which a corrosion-resistant metal is dispersed and adhered to a required welding portion by a method of the present invention in advance when two galvanized or zinc-based alloy-coated steel sheets are overlapped and welded. . In other words, this indicates that the corrosion-resistant metal spray 3 is sprayed from the thermal spray nozzle 2 on the target zinc-based plated steel sheet 1 and the corrosion-resistant metal 4 is dispersed and adhered on the zinc-based plated steel sheet 1.

とである。The dispersion adhesion of the corrosion-resistant metal 4 is preferably performed by the thermal spraying method shown in FIG. The thermal spraying method is a method of forming a coating by flying droplets, and is a very convenient method for producing the present coating. As a method, any of ordinary arc spraying (wire material, powder), flame spraying, plasma spraying and the like may be used. The coating can be easily controlled by controlling ordinary parameters of each method. At that point, the distance between the droplets is appropriately set (not too close to each other), the droplet ejection speed is matched with the scanning speed of the spray nozzle, and the droplet is reduced by as much as possible.
The purpose is to independently disperse one grain at the same size and at an equal distance.

It is possible to adhere to. In order to obtain a higher adhesion of the corrosion-resistant metal to the steel sheet, pretreatment such as degreasing or blasting may be performed in advance, but the contact between the steel sheet and the corrosion-resistant metal is strengthened by the welding itself after welding. The need is not high because it is reinforced. Further, for the same reason as above, it is generally not necessary to preheat the steel sheet itself.

A thickness of 0 μm or more was required. Further, when the height exceeded 500 μm, burn-through of the sprayed beads was observed.

ある。The main component of the corrosion resistant metal is zinc. In the first place, zinc is used because it makes use of the corrosion resistance of zinc to compensate for the decrease in corrosion resistance at the site where it is used. However, in general, zinc-based alloy plating is also used as a plated steel sheet for the purpose of improving the corrosion resistance of zinc. All of these zinc-based alloys can be used as the corrosion-resistant metal constituting the thermal spray. By increasing the amount of these alloys used, it is possible to further increase the corrosion resistance of the gap.

えられる。When the surface coverage of the galvanized steel sheet with the corrosion-resistant metal exceeds 55%, pits and blowholes occur during lap laser welding due to zinc vapor generated after melting of the corrosion-resistant metal containing zinc by the laser beam. In many cases, laser weldability cannot be ensured. Therefore, in order to achieve both good weldability and high corrosion resistance, the surface coverage of the galvanized steel sheet by the corrosion-resistant metal in the overlapped portion was limited to 50% or less. The reason for this phenomenon is 50
%, Even if the spray beam is applied to the corrosion resistant metal,
Even if zinc vapor is generated at the same time as plating, pits and blowholes do not occur because the surrounding space is sufficient, but if it exceeds 55%, the space and the amount of zinc vapor generated will reduce the pits and blowholes. It is believed that the resulting limit has been reached.

Galvanized steel sheets are often welded after being formed into various shapes. The above-described dispersion adhesion of the corrosion-resistant metal to the galvanized steel sheet according to the present invention includes a galvanized steel sheet which is formed, that is, in a component state before welding.
