置決めの開先倣いセンシング方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a groove tracing sensing method for cutting or welding positioning of three-dimensional structures such as boilers and turbine parts using electron beams or laser beams.

ビームである。As shown in FIG. 6, the conventional method for aligning grooves in electron beam welding of welded steel pipes 01 is to simultaneously align the fP seam grooves 0 and 03 horizontally, and to align the groove position 02 of the welded steel pipes 01 at the same time. After setting, perform electron beam welding. 04 is a steel pipe placement block, 05 is an electron beam gun, and 06 is an electron beam.

れ０８を生じてしまうことが多い。However, when welding is performed in this manner, as shown in Fig. 7, the groove cross section 02 of the welded steel pipe 01 does not necessarily pass through the center O indicated by 07 of the welded steel pipe 01, and as in electron beam welding, When using a welding method with a narrow beam X width, a much larger beam deviation 08 often occurs compared to the groove tolerance value 02, which is about 02.

ンシングを行う必要がある。Beveling and welding of welded steel pipe 01 is performed by thick plate press bending 1
After processing, the groove is machined and welded in close contact, but after welding on one side of the long steel pipe due to twisting, etc., the electron beam gun 05 or the welded steel pipe 01 is reversely moved in a vacuum c,,c
It is necessary to perform groove alignment by remote control while in a vacuum, or to release the vacuum and perform groove alignment sensing directly.
ところが上記の方法は、遠隔操作のため。However, the above method is for remote control.
精度が不十分であることや、真空排気の時間を有するた

致及び溶接形鋼管表面での開先幅方向のビーム位置中心
と開先幅方向中心との一致が少なくとも必要である。In conventional technology, the positioning accuracy of the groove for welded steel pipes is not up to the required groove accuracy for welding with narrow bead widths such as electron beam welding, and therefore, careful groove alignment is required. In particular, it is necessary at least to match the beam axis with the cross-sectional groove line, and to match the beam position center in the groove width direction on the surface of the welded steel pipe with the groove width direction center.

れを生じやすい。Sensing technology in which the center in the groove width direction coincides with the center of the beam axis enables high-precision positioning by utilizing CNC-controlled X-ray sensing, etc.; In the case of welded steel pipes, sensing positioning technology for the groove line (in the radial direction) and the beam axis currently only allows for visual setting, which is insufficient in terms of accuracy and tends to result in misalignment.
加えて、現状の上記セツティングは、真空解除した状態

次元開先倣いセンシング方法を提供するものである。In order to solve the above problems, the present invention attaches a tab plate having a triangular pyramid shape or a microhole to both end faces of the workpiece, irradiates a weak beam to a target point, and adjusts the beam irradiation point within the tab plate surface. This is a groove tracing sensing positioning method that sets two points in a three-dimensional coordinate system and aligns the beam axis attitude with the groove cross-section weld line. In other words, in a welding method that performs welding in a straight line with a high-energy beam such as an electron beam or a laser beam, welding is carried out in a straight line on the extension line of the surface of the groove sensing tab plate temporarily fixed to the upper end of the weld groove line extension of the workpiece. Two micro holes are provided in the
The beam irradiation point is precisely positioned using a three-dimensional coordinate system connecting the two microholes and the electron beam gun, and the beam axis posture 1. The present invention provides a three-dimensional groove tracing sensing method characterized by highly accurate tracing control of the groove center.

開先倣いセンシング方法である。Since the three-dimensional groove tracing sensing method of the present invention is the sensing method described above, it is possible to sense two points in the three-dimensional coordinate system using the tab plate for controlling the beam axis attitude, and the control signal is It is possible to control the posture of the base material workpiece or the electron beam gun.The use of a turning table or turning roller that controls the posture of the base material workpiece even in a vacuum, and the adoption of a moving electron beam gun, make it possible to control the posture of the base material workpiece or the electron beam gun. This is a three-dimensional groove scanning sensing method that enables positioning of electron beam gun attitude control with high precision and remote control in a short time.
