Abstract

PURPOSE:To improve strength of a joined part of beltlike metal plates and to prevent the joined part thereof from rupturing by increasing welding output of the central parts of the beltlike metal plates and rolling the welded and joined part at the time of welding and joining the ends of the beltlike metal plates to each other. CONSTITUTION:The beltlike metal plate 10 is rewound and conveyed to a joining device 16 and cut by a pre-cutting device 18 and arranged so as to be able to be abutted accurately or superposed slightly on the rear end 22A of the metal plate 22. The tip 10A and the rear end 22A are then welded together by a welding torch 30 of welding equipment 24. In this case, when a welding current between butt parts A-B and C-D and a welding current between butt parts B-C are denoted by E1 and E2 respectively, E2 is made higher than E1. By this method, welding of the central parts is performed satisfactorily by making the welding current E2 of the central parts of the metal plates higher than the welding current E1 of both ends. In addition, joining strength is further increased by rolling the joined part by a rolling roller 34 of a rolling device 32.

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for joining strip-shaped metal plates, and particularly to a joining method for joining end portions of flexible strip-shaped metal plates.

Methods for joining belt-shaped metal plates include a method in which the belt-shaped metal plates are joined by overlapping each other, and a method in which the belt-shaped metal plates are joined by butting each other. FIG. 4(a) is a perspective view showing a conventional overlapping joining method. As shown in FIG. 4(a), a band-shaped metal plate 70
and the end of the band-shaped metal plate 72 are overlapped, and the joining surface 73 is adhered with double-sided adhesive tape or fused by ultrasonic waves (see No. 4 of Japanese Patent Laid-Open No. 59-24526). (Fig. and Fig. 6).

Further, FIG. 4(b) is a perspective view showing a conventional butt joining method of band-shaped metal plates. As shown in FIG. 4(b), the ends of the band-shaped metal plates 70, 72 are butted against each other, and the butted joint portion 75 is joined with one-sided adhesive tape 76, 76 (see JP-A No. 59-24526).

However, in the conventional method of joining band-shaped metal plates as shown in FIG. 4(a), there is a step at the joining part, so it is not possible to make smooth contact with a pass roller or the like. Further, in the photosensitive layer coating process in the manufacture of lithographic printing plates, the coating device must be evacuated to prevent damage when the joint portion of the band-shaped metal plate passes through. Further, if the coating device is not retracted, the bonding surface 73 will have a negative effect on the coating state and cause quality defects.

In addition to this problem, since the joint surface 73 is often not bonded over the entire surface, the joint surface 73 may be bonded while the strip is being transported.
3 may be turned over. In addition, if there is a surface treatment process for the strip metal plate using a treatment liquid, when the strip metal plate passes through the treatment liquid, foreign matter such as the treatment liquid may enter the gap between the joint surfaces 73. This may cause quality defects in subsequent processes.

Furthermore, in the joining method by butting shown in FIG. 4(b), since the joining is performed using the one-sided adhesive tape 76, 76, a difference in thickness occurs at the joining portion due to the tape 76, 76. This level difference causes a problem similar to the problem in the overlapping joining method shown in FIG. 4(a). In particular, in the case of this method, the tape 76, 76 at the abutting section is damaged by the edge of the strip at the abutting section while being conveyed through the process by a bus roller, etc., which weakens the strength and makes it easy to cut. There is a point. Furthermore, such a bonded band-shaped metal plate receives bending stress when passing through the bus roller, but
This bending stress makes it easy for the joint to break. This phenomenon is particularly noticeable when the belt-like plates are thin, such as 0.1 mm to 0.2fflI11, or when there is a large difference in thickness between the two joined belt-like plates.

In order to solve these problems, a joining method has been disclosed in which band-shaped metal plates are welded together and the welded joint is rolled to eliminate the level difference.

However, when band-shaped metal plates are welded using such a conventional welding method, good welding is possible because there is no place for thermal energy to escape at both ends of the band-shaped metal plate, but at the center, thermal energy is absorbed at both ends. Since it is easily transmitted to the parts, poor welding occurs frequently.

A welding device 24 is provided downstream of the bricutting device 18, and the welding device 24 includes a clamp 26, 28 and a welding torch 3.
It is composed of Q. A strip metal plate 10 is attached to the clamp 26.
The front end 10A of the band-shaped metal plate 22 is held by the clamp 28, and the rear end 22A of the band-shaped metal plate 22 is held by the clamp 28. Therefore, the tip 1
0A and rear end portion 22A are butted against each other, as shown in FIG. The welding torch 30 moves from position A to position D of this abutting portion shown in FIG. 2 to weld the end portions 10A and 22A of the band-shaped metal plates.

In this case, as shown in FIG. 3, the welding current between the butt portion A and B (the left end of the strip metal plate in FIG. 2) is set to El,
E2 is the welding current between the butt portion B and C (the center of the strip metal plate in Figure 2), and the welding current between the butt portion C and D (the right end of the strip metal plate in Figure 2) is E2. Set to El. As described above, since the welding current E2 is larger than the welding current E1, sufficient melting occurs between the abutting portions C and D.

A rolling device 32 is provided downstream of the welding device 24, and the rolling rollers 34 of the rolling device 32 are arranged at the end portions 10A and 2 of the strip metal plate.
Rolling of the welded joints between 2A is carried out. By such rolling treatment, the step formed in the welded joint is suppressed and compressed. This rolling treatment increases the bonding strength. This is because the tensile strength reduced by welding is recovered by work hardening through rolling treatment, and at the same time, the material is processed into a shape that is less likely to cause stress concentration. In addition, when the strip-shaped metal plate 10 and the strip-shaped metal plate 22 are bonded together with minimal overlap, a rolling process is particularly required.
