| 摘要 | In a multi-electrode welding torch, electrodes (2) are configured into a shape that has an arc-shaped curved surface area (R) in at least a portion of a cross-section thereof that is orthogonal to the longitudinal direction thereof. Collets (4) are each provided with a groove portion (4a) in which an electrode (2) is fitted, and whose inner wall surfaces (4b) come into contact in a plurality of locations with the curved surface area (R) when viewed in the longitudinal direction of the electrode (2). | ||

| 主权项 | 1. A welding torch comprising: a plurality of electrodes that are insulated from the welding torch by an insulating material; and collets that are in contact with the electrodes and conduct power to the electrodes, wherein the electrodes are shaped such that they have an arc-shaped curved surface area in at least a portion of a cross-sectional shape thereof that is orthogonal to the longitudinal direction thereof, each collet is provided with a groove portion in which the electrode is fitted, and whose inner wall surface is in contact with a plurality of locations of the curved surface area of the electrode along a cross-section thereof that is orthogonal to the longitudinal direction of the electrode, and there are provided projecting portions that protrude from inner wall surfaces of the groove portion, and engagement holes that are provided in the electrode and with which the projecting portions engage. | ||
