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).

Two or more superposed plates and a thin plate are resistance-welded by: placing, on the two or more superposed plates, the thin plate whose thickness is less than each of the two or more superposed plates; placing a welding auxiliary member on the thin plate; making one of a pair of electrodes abut on the welding auxiliary member, and making the other of electrodes abut on a bottom surface of a lowest plate of the two or more superposed plates; and resistance-welding the two or more superposed plates and the thin plate to one another by the pair of electrodes.

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).
