摘要： A welding deformation computing method for computing welding deformation in a relatively short time while maintaining high deducing accuracy of the welding deformation by carrying out convergence computation in such a way that nonlinear analysis of only the portion near a welded portion is carried out to maintain continuity with the linear analysis result, a welding deformation computing device, a computer program, and a recording medium. A limit surface representing a limit of a region for which nonlinear analysis is necessary at a predetermined time point is determined in reference to the stress distribution and the temperature distribution, the region for which nonlinear analysis is necessary is extracted, the displacement and reaction force at the limit surface are computed by linear analysis of the object to be welded, the reaction force at the limit surface is computed by nonlinear analysis of the region for which nonlinear analysis is necessary, an amount of correction of the displacement at the limit surface is computed and the above processing is repeated if it is judged that a difference between the two reaction forces is larger than a predetermined value, and welding deformation of the object to be welded is computed based on the computed displacement if it is judged that the difference between the reaction forces is smaller than the predetermined value.

摘要： The aim of the invention for a narrow-gap arc welding process of shaft parts is to easily and effectively improve the quality of a first tubular annular seam (17) when testing a weld joint of a shaft (1), particularly for a turbine and/or a generator. According to the invention, the quality of the first tubular annular seam (17) is assessed from within a hollow chamber (15) during and/or after welding by means of a detection device (19) or a radiation source (19a) introduced into the hollow chamber (15) from outside said chamber through a passage (18). A video camera is particularly suitable as a detection device (19). In this manner, the welding procedure can be directly regulated.

摘要： The present invention relates to a method (500) for monitoring and/or regulating the quality of spot welds of a resistance welding gun (100), wherein the method comprises a step of measuring and storing measured values (220, 230) during the execution of resistance spot welds at different points on a workpiece. The measured values (220, 230) represent a voltage, a current, a resistance, a welding time, an energy, a force on welding contacts and/or an output during the production of a resistance spot weld. Furthermore, the method comprises a step of comparing the measured values (220, 230) with a reference measurement value (200), wherein the reference measurement value (200) represents a corresponding voltage, a current, a resistance, a welding time, an energy, a force on welding contacts and/or an output during the production of a corresponding resistance spot weld. Finally, the method comprises a step of outputting a warning message (250) when, during the comparison step, it is established that a predetermined number of successive measured values (230) is outside a predefined tolerance band (210) from the reference measurement value (200).

摘要： A welding system has: a welding mechanism, a reception laser light source, a reception optical mechanism, an interferometer, a data recording/ analysis mechanism and a data recording/ analysis mechanism. The reception laser light source generates reception laser light so as to irradiate the object to be welded with the reception laser light for the purpose of detecting a reflected ultrasonic wave obtained as a result of reflection of a transmission ultrasonic wave. The reception optical mechanism transmits, during or after welding operation, the reception laser light generated from the reception laser light source to the surface of the object to be welded for irradiation while moving, together with the welding mechanism, relative to the object to be welded and collects laser light scattered reflected at the surface of the object to be welded.

摘要： The invention relates to a quality control method for ultrasound welding. In order to carry out very sensitive process monitoring, the method provides for the generation of a tolerance range which is adjusted to the progress of the welding process and which is generated from measured values which influence the welding process. According to the invention, a method is proposed for quality control for ultrasound welding, wherein a measured value tolerance range is determined from measured values of executed welding processes, said measured values being associated with at least one parameter which influences the welding process and/or represents the goods of the welding process. Measured values which are associated to an identical parameter of a further welding process following thereafter are considered during the quality monitoring in such a way that the measured value tolerance range is changed in its form or composition to an average value for further welding processes, in accordance with the variance between the additional measured values and the tolerance range determined from previous measured values.

摘要： Should several simultaneously-operating, functional elements (2) be required on processing workpieces (10, 11), a particular support arrangement for the functional elements is thus required, in order to hold the above in the working position thereof, even in the case of curved machining paths. Said support arrangement comprises a base (12) with supports for the functional elements arranged thereon in adjustable positions. The supports are preferably in the form of ring structures (60) and the functional elements arranged in the inner volume thereof, whereby a drive mechanism works externally on the supports, to turn the same.
