摘要： A two-electrode arc welding device and two-electrode arc welding method are provided for performing welding with improved penetration performance using two non-consumable electrodes. In a two-electrode arc welding device, a power-supply unit outputs a straight-polarity voltage and a reverse-polarity voltage, which has a different electrical potential than the straight-polarity voltage. The straight-polarity voltage output from the power-supply unit is applied to a non-consumable electrode of a straight-polarity arc torch, whereby an arc is formed. The reverse-polarity voltage output from the power-supply unit is applied to a non-consumable electrode of a straight-polarity arc torch, whereby an arc is formed. An arc spacing distance, which is a distance between the ends of both the straight-polarity arc torch and the reverse-polarity arc torch, is set to be at least a minimum distance at which an arc will not occur therebetween (arc spacing critical distance).

摘要： A two-electrode arc welding device and two-electrode arc welding method are provided for performing welding with improved penetration performance using two non-consumable electrodes. In a two-electrode arc welding device 1, a power-supply unit 11 outputs a straight-polarity voltage and a reverse-polarity voltage, which has a different electrical potential than the straight-polarity voltage. The straight-polarity voltage output from the power-supply unit 11 is applied to a non-consumable electrode 41 of a straight-polarity arc torch 14, whereby an arc is formed. The reverse-polarity voltage output from the power-supply unit 11 is applied to a non-consumable electrode 41 of a straight-polarity arc torch 15, whereby an arc is formed. An arc spacing distance L1, which is a distance between the ends of both the straight-polarity arc torch 14 and the reverse-polarity arc torch 15, is set to be at least a minimum distance at which an arc will not occur therebetween (arc spacing critical distance).

摘要： A magnetic field is generated in a workpiece in a direction orthogonal to the joining direction, and as a result of the Lorentz force resulting from the magnetic field and the current between the plasma torch and the workpiece, the front tip side of the arc is bent forward in the direction of advancement of the plasma torch and welding is performed. The magnetic field strength of the welded part is adjusted by changing the relative positions of the plasma torch and a butting portion of the workpiece.

摘要： An element such as Cr is caused to dissolve sufficiently in a base-material metal (Cu) in a solid solution state at a high temperature and a material in a supersaturated condition is obtained by performing quenching. After that, a strain is applied to this material and this material is subjected to aging treatment at a low temperature simultaneously with or after the application of this strain. As a result of this, it is possible to obtain a copper alloy having properties desirable as an electrode material, for example, a hardness of not less than 30 HRB, an electrical conductivity of not less than 85 IACS %, and a thermal conductivity of not less than 350 W/(m·K).
