In this case, α is a welding margin, which is selected to be a dimension at which a welded portion can be formed by welding described later. The welding margin α is appropriately selected depending on the material of the constituent member 201, the thickness t, the height of the projection 210, and other conditions. In addition, spot welding, resistance welding,
Brazing or the like can be appropriately selected.

Next, reference numeral 211 denotes a relief hole,
It is formed at a position corresponding to 10 through the component member 201.

A welding power source (not shown) formed so as to be selectively operable is connected between the pressure bonding punch 58 and the mounting table 72.

When the constituent members 201 to 204 are to be punched out, the constituent members 201 to 204 have the punched hole 35 (see FIG. 7) formed in the workpiece 4 serving as a die, and As shown in FIG. 10, the dowels 209 are engaged with the dowel holes 205 and the welded portions 215 are formed at the tips of the protruding portions 210 between adjacent components. Therefore, integration becomes possible. Note that the holding device 5
Since the hole 55 provided in the upper holding plate 56 is formed larger than the maximum outer contour of the constituent members 201 to 204, it can pass through any of the constituent members 201 to 204 without any trouble.

The supporting device 53 for supporting the components 201 to 204 is constituted by
It is preferable that every time the lamination and press-bonding 204 is performed, the structure is lowered by an amount corresponding to their thickness dimension and stopped at that position. After the stacked body 200 shown in FIG. 3 is formed as described above, the stacked body 200 is discharged from the supporting device 53, and the next stacked bonding is repeated. The continuous operation of the entire apparatus by installing a plurality of the laminating apparatuses 5 is the same as that in the above-described embodiment.

In the above embodiment, an example has been described in which the positioning between the components is performed by engaging the dowel holes with the dowels. However, the present invention is not limited to this. It may be perforated and engaged via a guide pin at the time of lamination, or the outer contour of the component may be engaged with the guide pin for positioning.
