Title:
Arc welding equipment
Document Type and Number:
Japanese Patent JP6344203
Kind Code:
B2
Abstract:
Arc welding equipment for joining the objects at high speed and for reducing the strain of the objects after being joined is provided. The nozzle housing an electrode forming arc plasma is formed from a gas supply part and a gas suction part. The gas supply part has gas supply holes supplying gas outward in a radial direction of the arc plasma. The gas suction part suctions the gas supplied form the gas supply part. A pair of the gas supply holes, which are disposed so that the electrode is disposed therebetween, supply the gas of a first pressure to a position away from the electrode by a first distance. A pair of the gas supply holes, which are disposed so that the electrode is disposed therebetween other than the pair of the gas supply holes, supply the gas of a second pressure to a position away from the electrode by a second distance. The second distance is longer than the first distance. The gas of the second pressure is lower than that of the first pressure. Thereby, the arc plasma is compressed in a direction connecting the gas supply holes, and the arc plasma becomes long in a direction connecting the gas supply holes.
