置に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laser welding device, and more particularly to a laser welding device that improves the supply of filler wire supplied from the outside in order to increase the strength of the welded portion during laser welding.
【０００２】0002

手段により集光し、高密度化し、金属あるいは非金属加

接、高速溶接を特徴とする接合手段として、レーザ溶接
の適用が高まりつつある。BACKGROUND OF THE INVENTION In recent years, it has become common practice to condense laser beams using condensing means such as lenses to increase the density of the laser beam and apply it to metal or non-metal processing. In particular, laser welding is increasingly being applied as a joining means characterized by low strain welding and high speed welding.

ーザビーム径が非常に小さいため、溶接される加工部に
より生成される溶接線は精度が要求される。However, compared to arc welding, which is widely known as a joining method, laser welding uses a different essential form of energy, so it has less margin in terms of weldability, such as weld line accuracy. Extremely small. That is, since the diameter of the focused laser beam is very small, precision is required for the weld line generated by the processed part to be welded.
【０００４】さらに、被溶接材としての加工物の大きさ
などにより、精度を維持するには自ずと限界が生じる。
そこで、レーザビーム径よりおおきな溶融部を形成し、
溶接線精度に対する裕度を拡大することがレーザ溶接の
生産性を向上するひとつの手段と考える。Furthermore, there is a natural limit to maintaining accuracy depending on the size of the workpiece to be welded. Therefore, we formed a molten part larger than the laser beam diameter,
We believe that increasing the margin for weld line accuracy is one way to improve laser welding productivity.
【０００５】また、ＪＩＳ溶接用語による２枚の加工物

がとられる。Furthermore, according to butt welding of two workpieces according to the JIS welding terminology, the thickness of the workpiece at the fused welded portion is generally smaller than the thickness of the non-welded portion. In order to compensate for this reduced thickness, measures are taken to supply the same or similar metal from the outside to replenish the reduced thickness and ensure strength.

This is an example focusing on the supply position when supplying filler wire in laser welding shown in Publication No. 4. In the figure, 2 is a nozzle that guides the laser beam 3; 4 is a wire guide nozzle that is arranged on the side surface of the nozzle 2 and guides the filler wire 7 fed from the wire feeding device; 9a, 9;
b denotes opposing workpieces, and a slight gap α is formed at the ends of these workpieces 9a and 9b, and the gap α is used as a guide groove for the filler wire 7. In order to feed the filler wire 7 to the gap α between the ends of the workpieces 9a and 9b without causing any deviation, the wire guide nozzle 4 is adjusted, and the filler wire 7 is fed to a predetermined position in the gap α. Correct it accordingly.

Moreover, laser welding is performed by moving the laser beam focus onto the extended plane (in the direction indicated by arrow A in FIG. 3) of the surfaces of the workpieces 9a and 9b (gap α).

くなる問題点があった。[Problems to be Solved by the Invention] Laser welding using the conventional filler wire 7 is performed as described above, and in order to feed the filler wire 7 to a predetermined position, the filler wire 7 is straightened and fed by the wire guide nozzle 4. However, the filler wire 7 is wound on a wire reel (not shown),
Therefore, when the filler wire 7 is released from the wire reel, it draws an arc with a relatively large curvature due to the elastic force of the material. The filler wire 7 is guided from a wire reel through a well-known route (not shown) and is fed by a wire feeding device (not shown) consisting of a pair of rollers (not shown), etc., and the wire guide is Send the laser beam to the focus via the However, as mentioned above, when the filler wire 7 is released from the wire reel, the length of the filler wire 7 coming out from the wire guide nozzle 4 is about 10 mm, and the filler wire 7 is twisted left and right. Rather than being deviated, the wire is rewound from the wire reel and deviated vertically, which is predominant. Even if lateral deviation occurs, it is only a small amount and has no effect on welding performance. has almost no effect. That is, the filler wire 7
is fed from the wire guide nozzle 4, causing the tip of the filler wire 7 to lift up and sticking in front of the laser beam (the filler wire 7 comes into contact with the surface of the workpiece 9 before the central axis of the laser beam). As a result, the filler wire 7 is not replenished stably, the amount of molten metal is not constant, and the tip of the filler wire 7 melts into particles, resulting in the welding itself not being maintained stably. was there.

する。Next, a laser welding method using the above-mentioned laser welding device will be explained. In FIGS. 1 and 2, the wire guide nozzle 4 positioned before welding is rotated by the electric motor 13 in response to a welding preparation signal (not shown).
The wire guide nozzle lifting device 14 is actuated by the rotation of the wire guide nozzle lifting device 14, and the wire guide nozzle lifting device 14 is lowered together with the wire guide nozzle lifting device 14. The tip 11 of the filler wire 7 guided by the wire guide nozzle 4 comes into contact with the surface of the workpiece 9.

However, during laser welding, the tip 11 of the filler wire 7 may separate from the surface of the workpiece 9 for some reason, for example, due to irregularities on the surface of the workpiece 9. Therefore, in the present invention, the detection means 10 is operated continuously to determine the contact state.

1 becomes open, and relay CR2 becomes OFF. Then, the contact CR2 in the circuit of the electric motor 13 is closed, the electric motor 13 rotates, the wire guide nozzle elevating device 14 operates, and the wire guide nozzle 4 descends. At the same time when the tip 11 of the filler wire 7 comes into contact with the surface of the workpiece 9, the power E1 is applied, the relay CR1 operates, and the contact CR1 is closed.Then, the power E2 is applied, the relay CR2 is turned ON, and the power E3 is applied, and the contact CR1 is closed. CR2 is opened and the electric motor 13 stops.

Since it is configured to be brought into contact with the surface of the welding material, problems such as lifting of the filler wire or melting of particles of the filler wire do not occur, so that a laser welding device capable of stable laser welding can be obtained. In addition, the effect was confirmed especially in aluminum welding.
