    摘要: A seam welding apparatus and a seam welding method perform a seaming process on workpieces of various shapes having flange sections, by preventing a welding track formed by upper and lower rotary electrodes from becoming displaced from a welding reference line established on the flange section. The seam welding apparatus includes two rotary electrodes for gripping the flange section therebetween while seam-welding the flange section, a support for synchronizing movements of the two rotary electrodes with each other in a widthwise direction of the flange section, a turning mechanism for pressing at least one of the two rotary electrodes toward the workpiece body, a roller that abuts against an end face of the flange section, and roller adjusting means for positionally adjusting the roller.

    摘要: It is an object of the present invention to provide a seam welding warpage prevention method and apparatus capable of preventing warpage caused by cooling contraction after welding, in a case where workpieces are different from one another in material and thickness, and thus not uniform in thermal contraction. In the seam welding warpage prevention method for welding a plurality of workpieces W1 and W2 that are not uniform in thermal contraction with respect to an energizing direction, the workpieces W1 and W2 are clamped with a pair of roller electrodes 23 and 33 while applying current. The welding is performed in a state where the roller electrode 33 that abuts on the workpiece W2 having higher thermal contraction is offset in an advancing direction ahead of the roller electrode 23 that abuts on the workpiece W1 having lower thermal contraction.

    摘要: A welding gun is provided in which moisture does not penetrate inside of a motor housing due to preventing the inside of the motor housing from becoming negative pressure. The welding gun includes a feed screw mechanism (40) that is coupled to a servo motor (10) and has a hollow rod (43) that reciprocally moves in a predetermined direction by way of torque applied by the servo motor (10), and a moveable electrode tip (62) that is connected to a leading end portion of the hollow rod (43) and opens and closes relative to a fixed electrode tip (61) according to the reciprocal movement of the hollow rod (43). The servo motor 10 has a motor housing (20) in which a motor housing hollow part (25) accommodating a portion of the hollow rod (43) to be reciprocally moveable is formed. A vent (21b) that ventilates the motor housing hollow part (25) with ambient air is formed in the motor housing (20).

    摘要: In a roller hemming method for folding a flange erected from a workpiece by pressing a working roller against the flange and moving the working roller relative to the flange, the flange is folded by: a first temporary bending step of bending a tip-side portion of the flange into a state that the tip-side portion is inclined; a second temporary bending step of bending a remaining, base-side portion of the flange into a state that the base-side portion is inclined; and a full bending step of bending the thus-bent flange into a final shape so that the flange is into contact with a flange-proximate portion.
