濤接法とよばれるものがある。(bj Prior Art O Explanation: Laser light has a high degree of energy and can be irradiated by concentrating the energy on one point; the optical path can be freely controlled using lenses, prisms, and rectangular mirrors; and the heating rate is Welding with a laser processing machine has an excellent performance of 9 mm.For example, when welding extremely thin plates with small thickness,
In conventional general welding, the amount of heat is roughly controlled, so it is difficult to join the parts to be welded by interlocking the appropriate amount, and S* of thin materials is difficult. A commonly used S* method is called the edge arc tangent method.

ていることが条件と1に為。Here, the conventional edge arc #I connection method will be briefly explained. Section 1111 is a description of the case where thin plates are connected by edge arc. 1m long lb objects to be welded are overlapped with their end faces 1c aligned, and the welded parts are shielded by spraying inert gas 3 with a TIG @ welding torch 2, and joined from 1k in conjunction. It is. Therefore, in the heliata series connection, the sew must be overlapped and the end surfaces must be uniformly aligned.
このことは1部材の接合において種々の制約を生じる仁

金属5をシいて接合するかあるいは板厚によって#i縞
2(b)図に示すように開先なしに溶接を行なうこと4
可能である。This results in various restrictions when joining one member, and for example, when joining plates that form corners as shown in Figure 2, pre-processing is required because heliarc welding is used. As shown in Figure 21a1, in the case of a general thick plate s11, the object to be welded is 1 m 1.
1 Make a groove 4 on either side of b and join by applying lfc@welding metal 5 there, or weld without a groove as shown in #i stripe 2 (b) figure depending on the plate thickness 4
It is possible.

満たすことは非常な工数増大となり損失が大きく余分な
予加工を省略できれば省資源。For example, #I 2 (As shown in Figure 07, edge arc welding becomes possible by once bending the vicinity of the end face of the S* object, lb, into a L-shape. Figure 2 shows a simple structure, If this is a complex structure, satisfying the above conditions would require a significant increase in man-hours, and resources would be saved if the extra pre-processing could be omitted.
省エネルギーの見地からもその効果は絶大である。The effect is tremendous from the standpoint of energy conservation as well.

! However, since the laser beam is irradiated in a narrow and focused manner, it is necessary to increase the processing precision of the welded part of the workpiece to a certain degree.For example, No. 3111#
If a gap is created between the objects to be welded 1a and 1b in the IC, welding cannot be performed without regret.

石。When processing 1IIIK thin plates, irregularities are likely to occur due to waviness and curling of the plate, so careful consideration must be given to these.As a countermeasure for such cases, as shown in Figure 4, welded parts -1a, A method of welding the workpiece by pressurizing the lb with a nozzle 7 for irradiating two radar beams and a chip 9 placed on the back side of the nozzle and then bringing the workpiece into close contact with the workpiece was considered.

考えられる。11b is made to fit inside the bellows.
The end portions 13m and 13b of the bellows that are to be mated are rotated by the drive unit 14 while controlling the speed to match the welding conditions. Laser light 1 emitted from
0 through the optical path control device 16 to the end portion 1 of the bellows.
The overlapping portion 4 of 3m and 13b was irradiated and the laser was bonded for 6 times. This device produces paper-shaped *m-shaped fields.
However, in this device I, it is necessary to increase the amount of pre-processing so that the end portions 13 and 13b of the bellows are in close contact with each other. Depending on this pre-processing, there is a possibility that the success or failure of joining the bellows may be affected.

In Fig. 6, the part S to be welded 1 m, lb is in close contact with its inner diameter, and the welding is performed by irradiating the Reniza light lO without pressing the joint part with the wheel provided on the cylinder 12 and the nozzle 7. There are nine things. 61st! l1b) is the leg part a of the nozzle.

In the one lotus joint shown, stress concentration occurs at the stepped portion 20, and t
In the angular deformation joint shown in Fig. 7(b) K, bending stress and concentrated stress act in a superimposed manner on the recess 21 in response to a load in the XX direction, and both of these causes a significant decrease in strength. According to another embodiment of the present invention, in laser welding of a flat plate, as shown in FIG.
d can be suppressed and a smooth joint can be obtained.
