PURPOSE:To blow off a molten metal and to perform gouging continuously by specifying the angle between an electrode wire and a base metal and the angle of the jet water injected to the base metal. CONSTITUTION:Underwater cutting of a stainless clad steel is accomplished by setting the angle between an electrode wire 1 and a base metal 2 at 25-70 deg. and generating an arc between the wire 1 and the metal 2 in order to remove only the stainless steel part in the water. The wire 1 is continuously delivered off according to the consumption thereof and the arc is generated without using a shielding gas. The jet water is ejected from a nozzle 3 at 20-65 deg. angle with the metal 2 from behind the arc generating point to blow off the molten metal. |
