摘要： A method and system of velocity control for an automatic welding apparatus, wherein at least either a welding torch or a workpiece is movable in the directions of the three rectangular axes and point-to-point (PTP) position control of the torch and workpiece is effected between two preset positions at a preset relative velocity. In effecting the PTP position control, the direction of movement is determined based on information about the two preset positions, and the components of the preset velocity in the directions of the three rectangular axes are determined based on the direction of movement thus found and also based on information about the preset velocity, these components being used as instruction velocities in the respective axes.

摘要： An increment type position control apparatus is adapted to evaluate a numerical value concerning a positional point by making subtraction between the data in a position feedback counter for counting a feedback pulse from an incremental encoder and the data in a commanded position buffer from a processor. Upon depression of an origin return command button provided on a control panel, the position feedback counter and the commanded position buffer are each loaded with a predetermined value, whereupon a pitch is given, whereby an object being controlled is controllably moved in the direction toward the origin. If and when the object being controlled exceeds the origin position, the same is stopped and the counter and the buffer are each again loaded with an appropriate numerical value, whereupon a given pitch is provided, whereby the object being controlled is moved in the direction toward the origin and comes to a point to almost exceeding the origin position. Just at the timing when the object being controlled is about to pass the origin position, the position feedback counter is set, whereby the data concerning the origin is regained in the apparatus.

摘要： An automatic welding apparatus comprises a welding torch including an electrode and a fixture for fixing a workpiece, and a relative positional relation of the welding torch and the workpiece fixture is controlled such that the electrode of the welding torch is moved to trace the welding line of the workpiece, whereby automatic welding is achieved. The automatic welding apparatus further comprises a switch for selectively connecting the electrode of the welding torch to a welding power supply or a detecting power supply, and a sensor for sensing a current or a voltage between the electrode and the workpiece when the electrode is switched to the detecting power supply, whereby the relative positional relation between the welding torch and the workpiece is detected in response to the output of the sensor, and thus a welding point or a welding line is sensed. In the case where the automatic welding apparatus is a wire extension type, adapted to successively feed the electrode in accordance with the progress of welding, a collet chuck for clamping the electrode to the welding torch is provided for fixing the length of the electrode from the welding torch on the occasion of the sensing mode.
