る。<Prior Art> Martensitic stainless steel strips have been widely used as materials for blades, for example, and their production is continuously performed through steps such as cold rolling, heat treatment and pickling.
特に、熱処理・酸洗工程では、鋼帯を連続的に処理する
必要があることから、先行する鋼帯と後続する鋼帯とを
例えばマッシュシーム溶接法を用いて直接溶接接続して
生産性の向上を図ろうとしている。In particular, in the heat treatment / pickling process, since it is necessary to continuously treat the steel strip, the preceding steel strip and the subsequent steel strip are directly welded and connected by using, for example, the mash seam welding method to improve productivity. We are trying to improve.

開示されている。As a means for eliminating such a defect, for example, Japanese Patent Publication No.
-43818 gazette, using a martensitic stainless steel welding rod, welded at a temperature range and a time range that is equal to or higher than the martensitic transformation start temperature and does not precipitate a ferrite phase and a carbide, and subsequently subjected to a post heat treatment welding. A method is disclosed.
しかし、この方法においても後熱処理を施すのに熱処理
設備を設けねばならず、設備費がかさむなどの問題があ
る。However, even in this method, heat treatment equipment must be provided to perform the post heat treatment, and there is a problem that the equipment cost increases.
本考案は、上記のような課題を解決したマルテンサイト

溶接法により下記の条件で溶接を施して接続した。<Example> As shown in FIG. 1, a connecting end is provided between a martensitic stainless steel strip 1 having a preceding width of 1000 mm and a thickness of 2 mm and a martensitic stainless steel strip 2 having the same size following. As the plate 3, an austenitic stainless steel plate having a length of 1000 mm, a width of 1000 mm and a thickness of 2 mm was interposed and welded by the mash seam welding method under the following conditions to be connected.
・溶接電流 :15kva ・溶接速度 :10m/min ・溶接加圧力:2.5t ついで、連続熱処理ラインに通板した結果、処理された
マルテンサイト系ステンレス鋼帯1,2の溶接部Ｗにはい
ずれも破断現象は認められなかった。・ Welding current: 15kva ・ Welding speed: 10m / min ・ Welding pressure: 2.5t Then, as a result of passing through the continuous heat treatment line, both of the welds W of the processed martensitic stainless steel strips 1 and 2 No breakage phenomenon was observed.
