An arrangement for determining the achievable adhesive strength before forming an integrally bonded connection at a surface of a joining partner, which arrangement comprises a broadband radiation source, a plurality of detectors and an evaluation unit, wherein the plurality of detectors are configured for a spatially resolved spectral analysis of electromagnetic radiation within a wavelength interval, are arranged in a row or a row and column arrangement, and are connected to the electronic evaluation unit and are arranged such that electromagnetic radiation emitted by the broadband radiation source impacts the detectors either after a reflection at the surface of one of the joining partners, a layer which is formed on the surface of a joining partner and with which the integrally bonded connection is formed, and/or after the irradiation of the joining partners transparent for the electromagnetic radiation, wherein the broadband radiation source is formed such that, on a surface of the joining partner from which the electromagnetic radiation is reflected or transmitted through the surface, an intensity of the electromagnetic radiation that is homogeneous laterally and in time is maintained, and the radiation is not absorbed 100%, and so an at least 2% transmission and/or reflection of the electromagnetic radiation is/are achieved and the electronic evaluation unit is formed such that the measurement signals detected by the detectors with spatial and wavelength resolution are detected within a wavelength interval for individual local points arranged on a predefinable surface of the joining partners, and measurement signals detected at several positions are in each case associated with a partial region of the detected surface (hypercube) and a data reduction is carried out for all measurement signals of the partial regions of the detected surface detected with wavelength resolution and in this process significant features are selected and on the basis of these selected features with previously determined regression model, which is stored in an electronic memory and which has been determined on the basis of the feature sets obtained in an analogous manner of joining partners connected to one another in an integrally bonded manner, the adhesive strengths of which were determined previously on samples using a different measurement method, the evaluation unit makes a prediction about a corresponding achievable adhesive strength. wherein the plurality of detectors are configured for a spatially resolved spectral analysis of electromagnetic radiation within a wavelength interval, are arranged in a row or a row and column arrangement, and are connected to the electronic evaluation unit and are arranged such that electromagnetic radiation emitted by the broadband radiation source impacts the detectors either after a reflection at the surface of one of the joining partners, a layer which is formed on the surface of a joining partner and with which the integrally bonded connection is formed, and/or after the irradiation of the joining partners transparent for the electromagnetic radiation, wherein the broadband radiation source is formed such that, on a surface of the joining partner from which the electromagnetic radiation is reflected or transmitted through the surface, an intensity of the electromagnetic radiation that is homogeneous laterally and in time is maintained, and the radiation is not absorbed 100%, and so an at least 2% transmission and/or reflection of the electromagnetic radiation is/are achieved and the electronic evaluation unit is formed such that the measurement signals detected by the detectors with spatial and wavelength resolution are detected within a wavelength interval for individual local points arranged on a predefinable surface of the joining partners, and measurement signals detected at several positions are in each case associated with a partial region of the detected surface (hypercube) and a data reduction is carried out for all measurement signals of the partial regions of the detected surface detected with wavelength resolution and in this process significant features are selected and on the basis of these selected features with previously determined regression model, which is stored in an electronic memory and which has been determined on the basis of the feature sets obtained in an analogous manner of joining partners connected to one another in an integrally bonded manner, the adhesive strengths of which were determined previously on samples using a different measurement method, the evaluation unit makes a prediction about a corresponding achievable adhesive strength.
