摘要： A method for adaptive control of the traveling electrode of a spot welding gun includes causing the traveling electrode of the welding gun to move at a first speed when performing a welding (working) cycle and to switch to a second speed at a point, the coordinate of which is calculated based on the point of contact of the coordinate of the electrode obtained at the configuration cycle performed before the working cycle. The method allows for a reduction in welding cycle time.

摘要： Distance to the upper face of workpieces W sandwiched between electrode rollers 15 and 16 is measured by a range sensor 41 that has a predetermined positional relationship with the electrode rollers 15 and 16 (STEPs 1, 3). Correction is made based on the distance found by the range sensor 41 by moving the pair of electrode rollers 15, 16 with reference to the workpieces W so that an angle Rx between a straight line L0 connecting centers of the pair of electrode rollers 15, 16 and the surface of the plurality of workpieces W is preset angle (STEP 5).

摘要： A positioning method of a spot welding robot, the spot welding robot having a movable electrode tip and an opposition electrode tip opposed to the movable electrode tip. The method sandwiches a work piece to be welded between the pair of electrode tips and includes driving the movable electrode tip towards the opposition electrode tip with a servo motor and stopping the movement upon contact based upon a prescribed current value. The method further includes measuring an open separation of two opposing tips between the movable electrode tip and the opposition electrode tip and moving the opposition electrode tip towards the moveable electrode tip based upon the preset value and the open separation of the two opposing tips.

摘要： A production line method of resistance welding comprising the steps of contacting a metal sheet with an electrode having an initial contact surface area at a force to provide a pressure to the metal sheet; applying a current though the electrode to the metal sheet; measuring dimensional changes of the electrode; correlating dimensional changes in the electrode to changes in the initial contact surface area; and adjusting the force to compensate for the changes in the initial contact surface area of the electrode to maintain pressure to the metal sheet. The force may be adjusted by stepping the force to maintain pressure to the faying surface of the metal sheet to be welded. By maintaining the pressure at the faying surface the life cycle of the electrodes may be increased without forming discrepant welds.

摘要： When the operation frequency is high, in order to cause the rate of change of outputs from an output terminal (OUT) to be abrupt, a selection control signal is caused to be in a low state, thereby causing MOS transistors (T5b, T6b) to be in ON states, thereby causing the combined resistance of the ON-resistances of the MOS resistors in a NOR gate (NOx) to be small. On the other hand, when the operation frequency is low, in order to cause the rate of change of outputs from the output terminal (OUT) to be gentle, the selection control signal is caused to be in a high state, thereby causing the MOS transistors (T5b, T6b) to be in OFF states, thereby causing the combined resistance of the ON-resistances of the MOS transistors in the NOR gate (NOx) to be large.
摘要翻译：当操作频率高时，为了使来自输出端子（OUT）的输出的变化率突然变大，使选择控制信号处于低状态，从而使MOS晶体管（T5b， T6b）处于导通状态，从而导致NOR栅极（NOx）中的MOS电阻器的导通电阻的组合电阻较小。另一方面，当操作频率低时，为了使来自输出端子（OUT）的输出的变化率平缓，使选择控制信号处于高电平状态，从而使MOS 晶体管（T5b，T6b）处于OFF状态，从而使NOR栅极（NOx）中的MOS晶体管的导通电阻的组合电阻变大。

摘要： A welding assembly is provided for welding a fastener to an object such as a vehicle body panel. The assembly includes a weld gun having first and second electrodes movable relative to one another between an open position and a closed position. The first electrode includes a housing assembly. A pin is received in the housing assembly and is movable when in said closed position between a desired nut position, and upside down nut position, and a no nut position. An optical sensor has a terminal end space from the pin for direction light thereon. The terminal end of the sensor received reflected light from the pin. A sensor control system processes the reflected light into a signal corresponding to one of the desired nut, upside down nut, and no nut positions.
