摘要： PURPOSE:To execute automatically and exactly profiling of a weld line by providing plural X axis and Y axis optical fiber sensors on the upper part of both corner parts of a groove, and connecting them to X axis and Y axis drivers through X axis and Y axis sequence circuits. CONSTITUTION:Both optical fiber sensors S are provided with a light emitting device and a photodetector, and an X axis optical fiber sensor is provided in the width direction of a groove 2, and divided into two of S1 ans S2 and installed at the outside of two groove lines 6, 6a, when a welding torch or a nozzle is on a weld line 3. Also, as for a Y axis optical fiber sensor, two are provided so that each installed height is different from each other, on the outside of the groove lines 6, 6a. Also, both drivers 9, 10 move the welding torch or the nozzle in the width direction of the groove 2 and the height direction of the groove 2, respectively. Moreover, both sequence circuits 7, 8 control an operation of the X axis and Y axis drivers 9, 10 based on a signal detected by the optical fiber sensor S.

摘要： PURPOSE:To execute exactly and automatically profiling of a weld line by providing plural X axis and Y axis optical fiber sensors on the upper part of one corner part of a groove, and connecting them to X axis and Y axis drivers through X axis and Y axis sequence circuits. CONSTITUTION:An optical fiber sensor S is provided with a light emitting device 11 and a photodetector 12, in which an X axis optical fiber sensor is in the upper part of the width direction of a groove 2, when a welding torch or a nozzle is on a weld line 3, and two of S1 and S2 are provided on both sides around a groove line 6. Also, as for a Y axis optical fiber sensor, two of S3 and S4 are provided so that each installed height is different from each other in the length direction of the groove 2. Both drivers 9, 10 move the welding torch or the nozzle in the width direction of the groove 2 and the height direction of the groove 2. Sequence circuits 7, 8 control an operation of the X axis and y axis drivers 9, 10 based on a signal detected by the optical fiber sensor S.

摘要： PURPOSE:To aim at enhancing and the quality of welding and at making the same uniform, by providing such an arrangement that the position of a torch section is controlled in accordance with the result of detection by a sensor section having a plurality of contactless detecting means which clamp welded shoulder sections of a workpiece. CONSTITUTION:A sensor section 1 which is laid in parallel with a welding torch section 12 directed toward the bevel section of a steel pipe 3, is projected downward from a deck 2 attached thereto with first to fourth slide members 21-24 to which position detectors (sensor lateral direction 31, a torch lateral direction 32, torch vertical direction 33, a sensor vertical direction 34) are pro vided respectively. Meanwhile the sensor section 11 has three optical displace ment type contactless distance measuring devices 11a, 11b, 11c. Further, the distance between the sensor section 11 and the bevel section 4 are controlled in such a manner that it is always set to a position which is the focal point of a lens. As a result, it is possible to aim at enhancing the quality of welding and at making the same uniform, and as well to enhance the productivity.
