まうという問題がある。[Problems to be Solved by the Invention] However, conventionally, when stud welding a stud bolt to a damping steel plate, the stud bolt can only be welded to one metal plate, so the connection between the stud bolt and the damping steel plate is difficult. The torsional tensile strength and bending strength of the joint were weak. For this reason, conventionally, additional welding points (spot welding) were used to supplement the joint strength, but in this case, it is easier to weld from one direction, and the range of application to production processes is wide. There is a problem in that the advantages of stud welding are lost.

In the method, an arc is intermittently generated between the one metal plate and the stud bolt, the arc heat burns out the resin interposed between the two metal plates, and welds the two metal plates, and then , the stud bolt is welded to the welded portion of both metal plates.

属板同士を溶着させることが可能となる。[Function] In this method of welding a stud bolt to a damping steel plate, first, an arc is intermittently generated between the stud bolt and one of the metal plates of the damping steel plate. This intermittent arc makes it possible to gradually melt the surface of one metal plate of the damping steel plate. The reason why the metal plate surface is gradually melted is that if a large amount of the metal plate surface is melted at once, the resin of the damping steel plate will burn instantly, and the combustion gas will blow away the molten metal, causing blowholes and This is because defects such as underfilling will occur. In other words, by gradually melting the metal plate surface, the gas generated by the combustion of the resin is gradually released, and the pair of metal plates can be welded together without destabilizing the arc or blowing away the molten metal. becomes possible.

とができる。Thereafter, a stud bolt is welded to the welded portion of both metal plates using normal stud welding. Therefore, the stud bolt is welded to the two metal plates, and the strength of the joint between the damping steel plate and the stud bolt can be increased. In the case of this welding method, compared to conventional stud welding, no special additional means are required, so the welding work itself is no different from conventional stud welding. In other words, the advantage of stud bolt welding, which is the ease of welding from one direction, can be fully utilized, and welding efficiency can be improved.

．． 3 and a resin 4 having an appropriate thickness,
The metal plate 2 and the metal plate 3 are joined with a resin 4 interposed therebetween. Reference numeral 5 indicates a holder of a stud bolt welding machine for welding the stud bolt 6 to the damping steel plate 1. The stud bolt 6 consists of a large diameter part 6a and a small diameter part 6b.
is the part to be welded to the damping steel plate 1, and the small diameter part 6b is
A threaded portion is formed. A conical projection 6C is formed on the top surface of the large diameter portion 6a, and the small diameter portion 6b is held by the holder 5 of the stud bolt welding machine.

タットボルト溶接の条件の５０〜８０％に設定される。First, as shown in Fig. 1 (a), the stud bolt 6
is held in the holder 5 of the stud bolt welding machine, and the protrusion 6C of the stud bolt 6 is brought into contact with one metal plate 2 of the control steel plate 1. Next, as shown at I in FIG. 1, the stud bolt 6 is separated from the metal plate 2 by about 1 rra while passing a current between the stud bolt 6 and the metal plate 2. As a result, an arc A is generated between the stud bolt 6 and the metal plate 2, and the metal plate 2 is gradually melted by the arc heat.
A melted zone M is formed. The welding current (1) and welding time (T1) in this case are set to 50 to 80% of the conditions for normal stud bolt welding, as shown in (1) in FIG.

設定される。When the generation of the arc ends, the stud bolt 6 descends again and comes into contact with the metal plate 2. Then, with a current flowing between the stud bolt 6 and the metal plate 2, the stud bolt 6 is separated from the metal plate 2 by about 1M. As a result, as shown at n in FIG. 1, an arc A is generated between the stud bolt 6 and the metal plate 2, and the other metal plate 3 is also melted by the arc heat. Therefore, in this state, the resin 4 interposed between the metal plates 2 and 3 is burned away by the heat, and is released as a gas to the outside. The welding current (2) and welding time (T2) in this case are also set at 50 to 80% of normal stud welding, as shown in (2) in FIG.

常のスタットボルト溶接の５０〜８０％に設定される。When the generation of the arc at the nozzle 9 in FIG. 1 is completed, the stud bolt 6 is lowered again, and the stud bolt 6 and the metal plate 2 are brought into contact with each other. After that, as shown in the mouth of Figure 1,
The stud bolt 6 was pulled up in the same manner as described above, and an arc A was generated between the stud bolt 6 and the metal plate 2, and one metal plate 2 and the other metal plate 3 were sufficiently melted by this arc heat. state. Welding current in this case ■3
The welding time 3 is also set to 50 to 80% of normal stud bolt welding, as shown in 3 of FIG.
このように溶接電流および溶接時間が小に設定された条

吹き飛びによる欠肉等の欠陥も防止される。Since the arc is generated intermittently under the conditions where the welding current and welding time are set to low values, the resin 4 will not be instantly burned by the arc heat, and the molten metal will be blown away by the gas from the resin combustion. It also disappears. Therefore, defects such as blowholes and underfilling due to blown away molten metal are also prevented.

行なわれる。As described above, when the arc is interrupted and interrupted, for example, 2 to 8 times, and one metal plate 2 and the other metal plate 3 are sufficiently melted, the welding conditions are automatically switched. In other words, the welding current and welding time in this case are
As shown in Figure 4, the stud bolt 6 is connected to the damping steel plate 1.
is set to a value that allows welding. As in this embodiment, when the thickness of the damping steel plate 1 is i, o, the welding current is set to about 900 A and the welding time is set to 50 m5, for example. Then, based on these welding conditions, an arc A is generated between the stud bolt 6 and the control (cinnamon steel plate 1), as shown in (E) of FIG. The stud bolt 6 and the damping steel plate 1 are joined together in a sufficiently large state.

めに実施していた、溶接作業も不要となる。Part (f) of FIG. 1 shows a state in which the stud bolt 6 is joined to the damping steel plate 1. In this case, the stud bolt 6 is joined to both of the metal plates 2.3 of the damping steel plate 1, that is, unlike the conventional case, the stud bolt 6 is joined to both of the two metal plates 2.3. Therefore, the static torsional strength of the joint between the stud bolt 6 and the damping steel plate 1 with a plate thickness of 1.0# is greater with the welding method W1 of the present invention than with the conventional welding method W2 shown in FIG. This eliminates the need for welding, which was conventionally performed to supplement the strength of joints.
