摘要： PURPOSE:To hold and control a torch for welding automatically to a proper position and posture and to carry out a labor saving and efficiency elevation by transmitting a torch position controlling signal to actuator with the image process of a video by a TV camera. CONSTITUTION:On the image picked up by a TV camera 10 a groove width, a position and projecting length of a welding wire 5 are calculated by an image processing device 12 and transmitted to a torch position and posture controlling device 18 as an output signal. On the other hand when one part of arc light detecting sensor 14 does not detect the arc light with the change in the posture of a torch 6, the output signal to the posture controlling device 18 is suspended and the inclination of the torch 6 is detected. The posture controlling device 18 compares with the reference value and outputs the signal holding the torch position to a certain conditions to driving moters 21, 24 are also outputs to a driving motor 25 the signal moving the inclination of the torch 6. A motor 21 drives the torch 6 up and down by driving a container 28 up and down and motors 24, 25 change the right and left direction and posture angle of the torch 6.

摘要： PURPOSE:To perform correct NC guided automatic welding by correcting the beginning and finish ends, the part where a plate thickness changes, the positions for starting creeping, starting jumping, the midway of a welding route, etc. by a magnetic sensor and oscillation sensor with respect to the welding operation by NC information. CONSTITUTION:The beginning and finish end, the change of a plate thickness, the aiming position of a torch, the distance between the torch and objects, etc. are detected by a magnetic sensor. The forward obstacle in the welding direction is detected and the positions for starting creeping and jumping are decided by an oscillation sensor. The deviation in the information is corrected by these detections with respect to the information incorporating NC and the correct NC guided automatic welding is accomplished.

摘要： PURPOSE:To perform narrow groove welding of thick steel plates of a wire curving type by automatic remote control with high accuracy by detecting the luminance of the arc light in the stage of bending a wire to the right and left. CONSTITUTION:A weld zone is monitored with a television camera and the luminance distribution of the arc light at the AA' line and BB' line near the weld zone in the groove is measured. The AA' line includes a welding wire 4 right under the top end of a torch 2 or chip 3 and is the line in the lateral direction at a right angle to the weld line. The BB' line includes an arc generation part 5 below the AA' line and is the line in the lateral direction at a right angle to the weld line. The relative positional relation between the part 5 and the side wall in the groove part is obtd. by binary-encoding processing of such luminance distribution and the conditions for welding procedure are controlled in accordance with the calculated value.

摘要： PURPOSE:To obtain an intact weld zone having a uniform bead shape by providing a coil near the weld zone to generate a shifting magnetic field, and applying the thrust in the direction opposite from the outflow direction of a molten metal on said metal that flows downward as a pipe inclines in its position according to its rotation. CONSTITUTION:A welding position 15 where a steel hoop 7 and a spiral pipe 14' contact with each other is internally welded by a welding torch and a shifting magnetic field heading toward the rotating direction (b) of the pipe is generated from a magnetic field coil L attached near a molten metal 22. As a result, the thrust in a direction F is acted on the molten metal 22 moving diagonally upward according to the rotation of the pipe and the outflow of the metal 22 going to flow downward by its own weight is prevented by such thrust. An electromagnetic stirring effect by the shifting magnetic field is generated in the metal 22 in this stage. The formation of a recess in the weld bead of the spiral steel pipe is thus averted and the intact weld zone is obtd.

摘要： PURPOSE:To improve the productivity without stopping the whole line, by performing sheet joint welding of strip at a reduced line speed. CONSTITUTION:At the jointing of strips 2, 7, the line speed is changed to a welding speed according to the thickness of the strips 2, 7 from a normal running speed by the order from a speed controlling device to a pinch rolls 3 and a main driving device 11. At the same time, a sheet joint welding device 5 travels in synchronizing with the change of line speed by a carriage 5a in the feeding direction of the strips 2, 7. After completing the welding of strips 2, 7 by the device 5, the speed controlling device returns the line speed to the normal running speed. Then the jointed strip is sent to a spiral pipe foming equipment.

摘要： PURPOSE:To improve welding efficiency by starting deceleration of wire feed speed from a high speed to a low speed just before the welding current changes from high current to low current in the pulse welding method which changes the feed speed of a fly wire according to welding current value. CONSTITUTION:The material 18 to be welded and welding material 11 are pulse- welded by melting a fly wire 8 by the arc generated between the end of an electrode 13 and molten pool 10. In this case, the control signal in which welding current is peak current out of the control signal emitted from a controller 1 with timer by a control signal discriminator 5 is transmitted directly to a welding power source 2 by bypassing a time limit lag delay timer 6. The control signal in which welding current is base current is transmitted to the welding power source 2 by way of the time limit delay timer 6. In this case, adjustment ability of about 0.1-0.01sec is usually possessed to the time limit delay timer 6. By the action of this control system, the deceleration delay time of the wire feed system is made virtually none and the welding of high performance may be performed.

摘要： PURPOSE:To smoothly perform foil seam welding of thick plate materials by providing more than a pair of rotary auxiliary electrodes before the welding advance direction of a pair of rotary main electrodes which sandwich the base metals by way of foils and stepwise elevating the temperature in the base metal while suppressing the temperature rise of the foils. CONSTITUTION:A pair of rotary auxiliary electrodes 9 which disposed two base metals 1 of plates by way of foils 2 similar to a pair of rotary electrodes 8 which sandwich the butt portions of said base metals 1 by way of the foils 2 are disposed slightly before the welding advance direction of said electrodes 8. Even at the welding of the plates by this device, current may be supplied at the permissible current value or less. While the base metals 1 and foils 2 are passing the electrodes 9, the foils 2 are cooled by the contact with the electrodes 9 whereby their temperature rise is suppressed and with the foils being held kept at a low temperature state only the central part of the base metals 1 is made to a high temperature state. Further while the base metals 1 and foils 2 are passing the electrodes 8, the foils 2 hardly cause temperature rise as compared to that while they are passing the electrodes 9 but the base metals 1 are difficult to receive cooling action from the electrodes 8 and therefore they rise further to a higher temperature state, to the melting point or more of steel, owing to supply current I', in which state welding may be accomplished.
