合さオする。In order to manufacture a steel plate frame by joining these steel plates and reinforcing frames, it has been common practice to temporarily fasten the reinforcing frames to the copper plates and weld them using a resistance welder or an arc welder. These methods often result in dents and weld distortions, which require the can to be repaired. This manual work requires skill and a great deal of time, and the indentations require putty processing in the pretreatment process before painting. As mentioned above, resistance welding or arc welding machines have the disadvantage of causing indentation and welding distortion.As a way to prevent this disadvantage, as shown in Figs. 1 and 2,
There is a method of joining a copper plate and a reinforcing frame using a laser. That is, as shown in FIG. 1, a steel plate 1 and a reinforcing frame 2
A laser beam 4 generated by a carbon dioxide gas radar device 3 is refracted by a reflecting mirror 5, condensed by a condensing lens 6, and irradiated with IR4 onto the surface of the reinforcing frame 2. When the reinforcing frame 2 is irradiated with the laser beam 4, a weld 7 is formed and the steel plate 1 and the reinforcing frame 2 are joined together, as shown in FIG.

問題が発生する。By the way, the tensile strength of the reinforcing frame 2 and the steel plate 1 is proportional to the welded cross-sectional area of the reinforcing frame 2 and the steel plate 1. The width W is extremely small compared to that of other types of arc welding. Therefore, securing tensile strength can be solved by increasing the welding length.
Since steel plate frames are used in structures that experience high levels of vibration, such as elevators and switchboard panels, this method has the disadvantage that sufficient fatigue strength and shear strength cannot be obtained. It is also conceivable to increase the beam diameter to increase the weld bead width in order to maintain sufficient strength, but this may cause other problems such as the welding area becoming larger.

である。Therefore, as shown in Fig. 3, there is a method of welding two or more welds to ensure strength, but this method requires increasing the time for opening and closing the beam shutter and shielding gas. This is a major drawback as it results in a loss of time in total density energy welding, which requires high-speed welding, such as the time required to move the beam scanner to a new welding start point and the time needed to make new setups.
本発明は上記の欠点に鑑みなされたもので、高速でかつ

As shown in the same figure (=(2. Copper plates l and i+u) The frame 2 is superimposed and the laser beam 4 is irradiated from the side of the reinforcing frame 2. When irradiating this laser beam 4, a program is written in advance to the NC controller 11. is input, and the XY beam scanner 13 is set to S under the control of the NC control device 11.
By moving it in the shape of a letter, the welded part 15 between the reinforcing frame 2 and the steel plate 1 is shaped as shown in FIG. 5 (-).

Furthermore, under the conditions for obtaining the same strength, the time for one step was shortened by more than 20% compared to the case of two-ferment welding beads shown in FIG. 4. This is a great advantage in manufacturing steel plate frames that require high-speed welding.
