IPC: B23K11/25
Filed: 1988-07-25
Abstract: PURPOSE:To stabilize welding quality and to reduce the number of shapings and replacements of electrodes by measuring tip areas of the electrodes before starting welding and during welding and regulating electric current concentration based on said measured areas to maintain it constant. CONSTITUTION:A holding tool 7 is provided to a rotation axis 6 and the same material piece 8 as a work is fixed thereon. Pieces of carbon paper 9 and transfer paper 10 are arranged on both surfaces of the material piece 8 which is made insertable between the electrodes 4 and 5. After welding is finished once, the electrodes 4 and 5 of a welding gun 1 sandwich and press the laminated pieces of transfer paper 10 and carbon paper 9 and material piece 8. At this time, the electrode tip shape areas are transferred to the pieces of paper 10 and the areas are calculated by cameras 11 and 12, a picture processor 13 and an arithmetic unit 14. The welding current concentration is then regulated based on the measured area and its value is always maintained constant. Accordingly, welding quality is stabilized and the number of shapings and replacements of the electrodes are reduced.

Abstract: PURPOSE:To improve quality for profile sewing in the corner part of working cloth by providing a profiling width setting means and defining profiling width from the edge of the cloth to a needle falling position as a new profiling width set value based on the detection signals of the first and second detectors when a presser bar is in a rising position and a sewing needle is in the needle falling position. CONSTITUTION:Since a sewing position control means commands the profile sewing to a drive control means according to the profiling width set value which is set by the profiling width setting means, a control means controls an actuator and the profile sewing is executed. On the other hand, when the working cloth is rotated in a prescribed direction for executing the profile sewing in the corner part of the working cloth, a profiling width changing means provided in the profiling width setting means detects it based on the detection signals of the first and second detectors that the presser bar is in the rising position and the sewing needle is in the needle falling position. Then, the profiling width from the cloth edge, which is detected by a cloth edge detector, to the needle falling position is defined as the new profiling width set value. As a result, the sewing position control means commands the profile sewing to the control means according to the new profiling width set value. Thus, the quality can be improved for base sewing or stitch sewing in the corner part of the working cloth.
