Abstract
PURPOSE: To make possible even welding by injecting arc-control gas toward the arc produced between filler core and base metals while controlling the same into pulse-form thereby moving and controlling the arc position.
CONSTITUTION: This is the method and device of welding for narrow groove welding, particularly welding of a small groove gap. A torch body 10 is disposed coaxially to a contact tip 14 and a filler core 16 is disposed axially slidably to the contact tip in the state that it is electrically contacted therewith. Welding current flows between the filler core and base metals 18 to form an arc 20. Shielding gas 22 is led from between a shielding cover 12 and contact tip, whereby welding action is done. On the other hand, a gas flow passage 24 consists of a number of through-holes penetrated along the axial direction and is tilted toward the filler core. Hence, the arc shape is deformation-controlled by the arc control gas 26 which is injected from the gas flow passage.
