MANUFACTURING METHOD FOR PLATE FOR WORK SUCH AS PLATE FOR CUTTING AND PLATE FOR TILLING

To provide a manufacturing method for plates for work such as a plate for cutting in which high-hardness materials made of metal dissimilar to metal of a substrate can be tightly installed in a wide range, by suppressing a heat shrinkage rate in brazing, which can improve a work function including a cutting performance and yet improve fastening strength and durability.SOLUTION: In a manufacturing method for plates for work such as a plate for cutting, divided high-hardness parts 6 in which high-hardness materials 3 in divided-shapes are melted to be brazed to a base material 4 for welding in advance are welded by the base material for welding to installation parts in a wide range so as to be arranged in parallel continuously and the high-hardness materials in the divided shapes are installed in a wide range so as to be arranged in parallel continuously.SELECTED DRAWING: Figure 3 【課題】ろう付けに際しての熱収縮差を抑えることで、基板とは異種金属の高硬度材を広範囲に強固に付設できることとなり、そのため切断性能などの作業機能を向上でき、しかも止着強度も耐久性も向上することができる切断用板などの作業用板の製造方法を提供すること。【解決手段】予め溶接用母材に分割形状の前記高硬度材をろう材を溶融してろう付けした分割高硬度材パーツ６を、広範囲の付設部にこの溶接用母材４により連続並設状態に溶接して、前記分割形状の高硬度材３を広範囲に連続並設状態に付設した切断用板などの作業用板の製造方法。【選択図】図３
