とが効果的である。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a method for joining metal plates, and more particularly to a method for joining metal plates in which band-shaped metal plates are butted against each other or partially overlapped and welded. [Technology] In addition to pressure welding and brazing, there are fusion welding methods for welding and joining strip metal plates together. This fusion welding method is a method of joining materials to be welded by melting them themselves, and includes gas welding, arc welding, and special welding using a laser or electron beam. In these welding methods, the ends of the band-shaped metal plates to be joined are butted against each other and welded (for example, JP-A-61-276770), or the ends are overlapped and welded. In particular, it is effective to weld thin strip-shaped metal plates by overlapping them by a small amount.

FIG. 3 is an observation diagram of the metal structure of a cross section of a welded joint joined by arc welding. As shown in Fig. 2, when cold-rolled strip metal plates 67 and 69 are joined together by fusion welding,
At the joint, a molten portion 71 that is melted and solidified is generated, and a recrystallized portion 73, 73 that is recrystallized by receiving welding heat for a certain period of time is generated around the molten portion 71. That is, the welded joint of the cold-rolled strip metal +fi67.67 consists of a molten part 71 that has melted and solidified, and a recrystallized part 73 that has been recrystallized under the influence of heat during welding, and the area around the welded joint is is the base material that has not undergone any melting, solidification, or recrystallization (
There is an original metal plate) 75, and three types of metal structures are formed at the joint portion of the band-shaped metal plates 67 and 69. Also,
Even in welded joints of metal sheets that are not cold rolled,
The melted part, recrystallized part, and matrix can be classified into 03 metal structures.

しかしながら、従来の溶接接合方法によって、帯状金属
板６７．６９の溶接接合を行うと、溶接接合部は本来の
帯状金属板６７．６９の厚みと一致しない場合がある。[Problems to be Solved by the Invention] However, when the strip metal plates 67.69 are welded together using the conventional welding method, the thickness of the welded joint does not match the original thickness of the strip metal plates 67.69. There is.
また、薄板の接合において２１１１１１１程度、望まし

板厚より大きくなる。Furthermore, when welding is performed by overlapping thin plates by about 2111111 mm, preferably by 0.5 mm to 1.5 mm, the thickness of the welded joint becomes larger than the original thickness of the band-shaped metal plate 67.69 mm.

に板厚の相違する金属板６７．６９同士を接合した場合
応力集中は顕著になる。If the thickness of the welded joint is significantly different from the original thickness of the strip-shaped metal plate 67.69, when a strip-shaped plate with such a welded joint is conveyed by being passed around a large number of pass rollers, stress will be generated at the welded joint. Concentration occurs and rupture is likely to occur. Particularly when metal plates 67, 69 of different thicknesses are joined together, stress concentration becomes significant.

不具合がある。In addition, the hardness and fracture strength of the base material 75, recrystallized portion 73, and molten portion 71 are as follows: base material > recrystallized portion ≧ molten portion, so the structure is arranged in the order of base material - recrystallized portion and molten portion. When bending stress is applied to a metal plate, the stress tends to concentrate in areas where the thickness changes greatly, and recrystallized areas with poor fracture resistance are located in these areas. For this reason, the band-shaped metal plate 67, 69 having the joint part by the conventional joining method,
If it is brought into contact with a large number of pass rolls, there is a problem that it will break in a short period of time.
本発明はこのような事情に鑑みて成されたちので、金属
板同士の溶接接合部の強度を高めて破断が生じない溶接
接合方法を提供するとこを目的とする。The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a welding method that increases the strength of the welded joint between metal plates and prevents breakage.

るように溶接接合部を形成することを特徴とする。In order to achieve the above object, the present invention is a welded joint of metal plates in which the ends of metal plates are welded together, and a molten part and a recrystallized part generated by the heat effect during welding are formed at the welded joint. In the method, the difference in thickness between the melted part and the recrystallized part is within 30%, and the difference in thickness between the recrystallized part and the original metal plate part that is not affected by heat during welding is within 30%. It is characterized by forming a welded joint so that the

及び溶接時の熱影響を受けない本来の金属板との厚みの
差が３０％以内であるため、金属板に張力又は曲げ応力
を与えた時にこれ等の応力が再結晶部分に集中し難い。According to the method for welding and joining metal plates according to the present invention, the recrystallized part of the weld joint that is prone to breakage has a thickness difference between the adjacent melted part and the original metal plate that is not affected by heat during welding. Since it is within 30%, when tension or bending stress is applied to the metal plate, it is difficult for these stresses to concentrate on the recrystallized portion.
この為、本発明に係る溶接接合方法による溶接接合部を
存した帯状金属板が張力を受けながら多数のパスローラ
に転接された場合でも、その接合部は強度が増して破断
しない。For this reason, even when a band-shaped metal plate having a welded joint formed by the welding and joining method according to the present invention is rolled by a large number of pass rollers while being subjected to tension, the strength of the joint is increased and the joint does not break.
