Abstract

PURPOSE: To let deep penetration welding, cutting, gouging, etc. be performed at high efficiency with the same device by flowing a specified amount of shielding gas from a hollow non-consumable electrode and digging down the melt zone.
CONSTITUTION: At the time of deep penetration welding of Al alloy, stainless steel, etc., helium gas or other is flowed as shielding gas 6 into a hollow electrode 3 to increase the arc potential of the central part of arc. As a result, the quantity of heat input becomes relatively high and deep penetration welding is accomplished. At the cutting or gouging, the rate of effluence of the shielding gas 6 from the hollow electrode 3 is increased to blow off the melt zone 9 by an arc flame 7. By changing the rate of effluence of the shielding gas 6 from the hollow electrode 3 in this way, the deep penetration welding, cutting and grouging are automatically accomplished.
