摘要： A method of controlling the synchronized movement of a backing shoe in an automatic one-side welding of the type in which a light-transmittable backing material is placed in close contact with the back surface of the welding joint and a backing shoe adapted to be moved along with the movement of a welding apparatus is pressed through the backing material against the back surface of the welding joint just below a welding electrode whereby effecting the welding. The method employs photoelectric detectors which are embedded in the surface of the backing shoe contacting the backing material at four positions, i.e., right-front, right-back, left-front and left-back positions just below the electrode with respect to the direction of welding and the detectors are arranged at predetermined distances from each other, whereby the light emitted from the back surface of the welding joint and transmitted through the backing material is received by the detectors each of which generates an electric signal corresponding to the received light magnitude and the speed of travel as well as the lateral position of the backing shoe are controlled in such a manner that the below-electrode-point is maintained at a predetermined position among the light receiving positions on the backing shoe.

摘要： In the multi-layer welding of a joint of two pieces of metal to be welded by arc welding, the proper number of passes and the desired tracing positions of a welding torch for each layer are automatically established during the welding of the preceding layer. The welding torch is subjected to a Y-axis control so as to maintain constant the arc voltage or current during the welding and simultaneously the torch is caused to weave in the direction of an X-axis within the groove. The tracing of the groove by the torch is accomplished by controlling the weaving turning positions of the torch in accordance with the X-axis and Y-axis direction displacement data of the torch and the torch displacements in the X-axis direction are compared with a predetermined value thereby determining the proper number of passes to be made in the welding of the next layer.

摘要： A welding method comprises rotating a nozzle (3) provided with a welding electrode (9) eccentrically from the center axial line (a) thereof within a groove (2). The center axial line (a) of the nozzle is aligned with the center of the groove (2) by smoothing values of variation in welding current or welding voltage for each of the left and right half cycles of the nozzle and controllably moving the nozzle horizontally at right angles to the welding direction so that the difference between these values becomes null. The height of the nozzle (3) relative to the groove (2) is maintained at a prescribed distance by smoothing values of variation in welding current or welding voltage and controllably moving vertically the nozzle (3) so that the difference between the thus smoothed value and a set value becomes null.
