(F) Effects of the Invention According to the overlay arc welding method of the present invention, it is impossible to manufacture a conventional overlay metal alloy with a crystalline structure, especially a continuous 1-beam band-shaped filler metal or a band-shaped consumable electrode with hardness.

In addition, amorphous band-shaped filler metals or consumable electroplating can have a larger width-to-thickness ratio than conventional crystalline thread (e.g., nickel-based) filler metals or consumable parts. In addition, resistance heat generation increases and the amount of melting increases. Furthermore, due to an increase in the melting amount of the amorphous strip-shaped metal foil or the consumable mold 6, the amount of weld metal supplied to the base material increases. Since the dilution ratio corresponding to the amount is very small, desirable results can be obtained for overlay welding.
