摘要： PURPOSE:To perform flat welding of both inner and outer faces continuously and efficiently in an automatic welding line, by communicating the inner face welding stage with outer face welding stage. CONSTITUTION:The inner face flat welding of a steel pipe having a tab plate fitted to both end parts of weld line in the longitudinal direction is carried out in welding stage A. Then, by rotating a turning roller Rt, the steel pipe is rotated at least angle theta1 in the circumferential direction so that the tab plate may not interfere with a conveying roller Rc. This steel pipe is sent into welding stage B, and is further rotated by the turning roller Rt, and the tab plate is detected by a tab plate detector 4 which is like a limit switch of a specified position, of which signal causes to stop the rotation of the roller Rt. Thus, after positioning the weld line, the outer face flat welding is performed from the upper part of the steel pipe. Besides, when welding in both stages, after placing the steel pipe, the roller Rt is raised or the roller Fc is lowered, and the weld line position may be adjusted by the tab plate detection by the detector.

摘要： PURPOSE:To maintain the projecting length of wires always adequately and to perform satisfactory butt welding of thick walled pipes automatically by moving two electrode holding parts upward and downward mutually independently by the signal from a detector. CONSTITUTION:When a succeeding electrode W approaches to a preceding start position, a detector 21 goes on and emits an operation signal to a motor 29 so that an auxiliary slider 30 moves upward by the rate A of deposition for 1 pass of a preceding electrode W'. When a pipe P makes one turn and the electrode W' approaches to a succeeding start position B, a detector 21' goes on, and a signal is emitted to a motor 9 so that a main slider 10 moves upward by the rate of deposition for one pass by the electrode W. The electrode W' moves upward by the rate A in the position B and the electrode W descends by the rate A. When the electrode W' arrives at the preceding start position and the succeeding electrode W arrives at the succeeding start position B, the electrodes ascend respectively simultaneously by the rate A. In such a way the pipe P is subjected to butt and tandem welding.

摘要： PURPOSE:To stop the turning rollers for pushing up the pipe in a correct position even if their mounting is inadequate and prevent the breakage of the welding apparatus by having the safety ascending limit of the turning rollers detected by a vertical tracing detector. CONSTITUTION:When an up command enters a drive unit 13, turning rollers are moved upward. Then, a pipe 1 detaches from conveying rollers 3 and keeps ascending by being held by turning roller device 6. The signal of the transmission part 24 of a vertical tracing detector 21 is inputted to the drive unit 13 which in turn stops the turning roller device 6 in that position. Next, the rollers of the turning roller device 6 are revolved to dispose the groove right above or right below. When welding is started, the transmission parts 25, 26 transmit upper threshold and lower threshold and therefore the welding head is elevated by an elevating motor 17 within these ranges. At the upper limit of the turning roller device 6, a limit switch 15 actuates.

摘要： PURPOSE:To prevent the disturbance of weld beads and melt-down of weld zones by comparing the rotating speed of the driving wheel with that of the driven wheel of a welding carriage, detecting slips and stopping welding. CONSTITUTION:If it i assumed that a driving wheel 4 slips during traveling of a welding carriage, the rotating speed of the wheel 4 exceeds the rotating speed of a driven wheel 3, and the output voltage of the 2nd tachogenerator 10 proportional to the rotating speed of the wheel 4 rises higher than the output voltage of the 1st tachogenerator 9. When the output of an amplifier 13 that amplifies the output voltage of the tachogenerator 9 lowers smaller than the output of an amplifier 14 that amplifies the output voltage of the tachogenerator 10, electric current flows between a comparator 15 and the base of a transistor 17, and the TR17 conducts to drive a relay 16, by which a welding stop signal is emitted and the welding is stopped.

摘要： PURPOSE:To prevent automatically generation of thickness deviation in a weld bea in the TIG arc welding stage in which welding is executed while a welding torch is oscillated by controlling the vertical and lateral movement of the welding torch by the voltage from a welding voltage detector. CONSTITUTION:Base metals 1 having the groove formed into an inverted trapezoidal shape are welded by a filler wire 4 of an electrode 3 while the welding torch 2 is vertically and laterally moved according to the groove shape. The arc voltage during welding is detected by a detector 16 and the voltage is inputted to a control part 17 in order to execute constant arc length welding. The signal for the vertical axial position of the welding torch 2 detected by an encoder 14 is inputted thereto at the same instant. The control signal for the vertical axial movement of the torch 2 is fed to a motor 13 for a vertical axial slider 12 and the control signal for the lateral axial movement is fed to a motor 11 for a lateral axial slider 10 in the control part 17 to control adequately the vertical and lateral movements of the torch 2 in order to maintain the specified length of the arc between the wire 4 and the base metals 1, by which the weld bead having no thickness deviation is formed.

摘要： PURPOSE:To stabilize welding arcs and to prevent the generation of welding defects such as lack of penetration by stopping a welding head which is controlled of automatic running while a welding electric source is in a short circuited state or in a no-load state. CONSTITUTION:When the leading end of a welding wire is brought into contact with the surface of the groove of base materials and welding is started, a welding power source is short circuited and the detected voltage signal Vx of the welding voltage detected with a voltage divider 18 is roughly zero. Therefore, the signal Vx is not applied to the 2nd decision circuit 21, the contacts 16-1 of a relay 16 are opened and the welding head stops in the set position. When the welding arc extinguishes on account of a certain cause later, that is, when the welding power source is put in a no-load state, the output voltage increases and the signal Vx of the voltage divider 18 increases as well. When the signal Vx exceeds the permissible upper limit voltage, the circuit 21 stops transmission to the relay 16 and the motor stops. Therefore, the welding head stops in the welding position where the welding arc extinguishes.
