However, the above-described flux brazing / soldering method, vacuum brazing / soldering method, and pressure welding method using a roller have various problems as described below. In the flux brazing / soldering method, the flux is often corrosive,
Cleaning is required after brazing and soldering. The residual flux that remains slightly after cleaning hinders the reliability of the joint. Most fluxes are usually liquid. Therefore, the flux cannot penetrate into the narrow gap and the effect cannot be exhibited.

In order to achieve the above object, in the method for joining metal plates according to the present invention, the surface of the metal plates is irradiated with an excimer laser as an alternative to the flux to wash and activate the metal plates. This promotes brazing and soldering. That is, by irradiating the surface of the metal plate at the joining portion with an excimer laser, the oxide film formed on the surface of the metal plate is decomposed and removed (ablation), the surface of the metal plate becomes clean, and the brazing material and solder material Wetting is promoted and good bonding is obtained. Further, since the laser beam can be applied to the fine portion, brazing and soldering can be performed even in the portion where the flux does not penetrate.

In particular, the excimer laser is suitable for decomposing and removing only the metal surface, and does not damage the inside of the metal. For example, when removing an oxide film such as Cu 2 O or CuO on the copper surface, the energy density of the excimer laser is 1 to 2
It is about 0 J / cm 2 . Further, in the method of joining metal plates, which joins the metal plates by pressure welding, the gap between the metal plates is irradiated with an excimer laser to remove surface stains from the surfaces of the metal plates. Immediately after exposing the surface of the activated and clean metal plate, both metal plates are pressure-welded to each other, so that good bonding can be obtained.

As described above, when the surface of the metal plate is irradiated with the excimer laser, the laser is absorbed on the extreme surface and the oxide film or the metal is decomposed and removed. As a result, the surface of the joint metal plate is in a clean and active state, and good joining with the molten brazing material / solder material can be performed, and also joining by pressure welding can be performed well.

This is an example of heating a heater while irradiating an excimer laser in a method of preliminarily bonding a brazing material / solder material to a metal plate bonding surface. For example, when preliminarily joining a brazing material and a solder material on a metal plate, as shown in FIGS. 1A and 1B, the metal plate 2 is heated by the heater 3 and irradiated with the excimer laser 1. However, if the brazing material / solder material 4 is supplied, good wetting can be obtained.

FIGS. 2A to 2C show a second embodiment, which is an example of heating using a high energy beam such as a CO 2 laser or a YAG laser. The excimer laser irradiation by this method may be performed at the same time as the irradiation with the CO 2 laser or the YAG laser, or may be performed after the excimer laser irradiation with the CO 2 laser or the YAG laser. As shown in FIGS. 2 (a) and 2 (b), CO 2 or YAG is attached to the metal plate 2.
By supplying the brazing material / solder material 4 while irradiating the laser 5, good wetting can be obtained. After the pre-bonding is completed as described above, as shown in FIGS. 2 (c) and 2 (d), the pre-bonded metal plates 1 are brought into contact with each other and heated by the heater 3 for brazing. Soldering is completed.

FIGS. 3 (a) and 3 (b) show a third embodiment, which is different from the first and second embodiments, in which a metal plate is brazed / soldered without performing pre-joining. . As shown in the figure, while the metal plate 2 is irradiated with the excimer laser 1, the brazing material / solder material 4 is supplied and heated by the heater 3. At this time, the excimer laser 1 irradiates a place (a boundary portion between metal plates) where brazing and soldering are performed as a target position.

FIGS. 4A and 4B show a fourth embodiment. In the third embodiment, CO is used instead of the heater.
This is an example of using a high energy beam such as a 2 laser or a YAG laser. As shown in the figure, the excimer laser 1 irradiates the vicinity of the mutual boundaries of the metal plates 2 to be brazed / soldered as a target position. The CO 2 or YAG laser 5 irradiates the portion to be brazed / soldered to the joining temperature. At this time, a laser (CO 2 or YAG) serving as a heat source may be branched and irradiated from two or more directions so that the laser light is not unevenly irradiated. It is also possible to irradiate while scanning the laser light. According to this method, since the heating heat source and the cleaning of the metal plate surface are both performed by the laser light, the local heating of the ultra-fine portion causes
Fluxless brazing and soldering are possible.

FIGS. 5 (a) and 5 (b) show an example in which the metal plates are joined by pressure welding, and the excimer laser is irradiated to clean and activate the metal plate surface. As shown in the figure, when the narrow gap between the metal plates 11a and 11b is irradiated with the excimer laser 1, the laser reflected on the wall surface gradually increases its energy density and travels deeply to process the processed surface. The irradiation of the excimer laser 1 removes the oxide at the bonding interface A between the metal plates 11a and 11b, which is the base material, and exposes the activated and clean surface. For example, Ar and He are sprayed in a direction perpendicular to the drawing, the removed oxide and the like are blown off, and the pressure welding is started from the pressure welding start point S which is substantially depending on the pressure roller 12. The layer removed by the excimer laser 1 is extremely small, on the order of a few μm, and is hardly affected by heat. Since the rolling is performed immediately after the activated surface is exposed, the rolling force may be small, and the plastic flow (deformation) of the base material is almost eliminated.
