Abstract: PURPOSE:To reduce the quantity of building up alloy and its cost used for forming a uniform deposition bead by making building up rotating the building up alloy bar clockwise around the axis to the direction of advance of a molten pool. CONSTITUTION:The building up alloy bar 7 is rotated clockwise to the direction of advance of the molten pool 6. Thereby, the the molten pool 6 is faced to backside 4 having large heat capacity. Accordingly, overflow of molten building up alloy to margin 3 side is reduced, and at the same time, the molten pool 6 flows in a fixed direction and a regular deposition bead is formed. Consequently, dispersion of the deposition bead 6 is reduced, and feeding of the building up alloy bar 7 is confined to a minimum.
