    <title language="eng">Potentials of the ALE-Method for Modeling Plastics Welding Processes, in Particular for the Quasi-Simultaneous Laser Transmission Welding</title>
    <abstract language="eng">The  Arbitrary-Lagrangian-Eulerian-Method  (ALE-Method) offers the  possibility to model the quasi-simultaneous laser transmission welding of plastics, in which a squeeze-flow of molten plastic occurs. It is of great interest to get a deeper understanding of the fluid-structure-interactions in the welding zone, since the occurring squeeze-flow transports heated material out of the joining zone, causinga temperature decrease inside.In addition, the numerical  modelling offers the possibility to investigate the flow conditions  in the joining zone. The aim of this article is to show the  potentials of the ALE-Method to simulatethe quasi-simultaneous laser transmission welding with the commercially available software LS-DYNA. The central challenge is to realize a bi-directionalthermo-mechanically coupled simulation,which considers the comparatively high thermal expansion and calculates the interactions of solid and melted plastic correctly. Finally, the potentials of the ALE element formulations for the mathematical description of welding processesare shown, especially for those with a squeeze-flow.</abstract>

    <title language="eng">Gap-Bridging during Quasi-Simultaneous Laser Transmission Welding</title>
    <abstract language="eng">Tightness is often the main requirement for quasi-simultaneous laser transmission welds. However, remaining gaps cannot be detected by the used set-path monitoring. By using a pyrometer in combination with a 3D-scanner, weld seam interruptions can be localized precisely while welding, due to temperature deviations along the weld contour. To analyze the temperature signal in correlation to the progress of gap-bridging, T-joint samples with predefined gaps are welded. The set-path is measured synchronously. Additionally, the temperature distribution and the influence of the thermal expansion of the polymers are studied by a thermo-mechanical FEM-process simulation. On top of that, the melt blow-out of the welded samples is analyzed using μCT-measurements. The experiments have shown that closing of a gap can be identified reliably by the temperature signal and that the squeezed melt flow into the gap and the thermal expansion in the gap zone accelerates gap-bridging. Furthermore the inserted heat can be adapted in the fault zone, in order to avoid thermal damage.</abstract>

    <title language="eng">Finite element analysis of thermoplastic probes under tensile load using ls-dyna compared to ansys workbench 14 in correlation to experimental investigations</title>
    <abstract language="eng">Joining thermoplastic requisitions is a popular technique to build  sophisticated plastic applications. Therefore the laser-transmission  welding process is used to join thermoplastic polymers in visible regions. The clamping force in this case plays a decisive role when  it comes to the weld quality. Simulating the clamping pressure with  finite element techniques is therefore highly attractive to understand the principal of the process. Thermoplastic polymers under tensile load often show a brittle behavior coupled with softening. Simulating  such materials is quite difficult for FEM programs. In this case a  finite element study of the tensile test in LS-DYNA and ANSYS Wb 14 with respect to the material models was analysed. The experimental  data get validated in comparison with the FEM solution for a tensile test. The material models and the problems in simulating softening behavior for thermoplastic polymers were discussed</abstract>

    <title language="eng">In-Situ Process Monitoring during Laser Transmission Welding of PA6-GF30</title>
    <abstract language="eng">Quasi-simultaneous laser transmission welding is preferably used for packaging sensors and electronics. In order to protect the components from moisture, a hermetic encapsulation is needed. However, local weld seam interruptions cannot be identified with the commonly used set-path monitoring. By using a pyrometer, coaxially integrated into a 3D-scanner, gaps between the joining partners can be allocated on basis of the measured temperature. However, the scattering of the heat radiation, especially caused by the fiber reinforcement of the plastics, leads to a reduction of the accessible heat radiation, which makes the identification of gaps considerably more difficult. The herein used experimental setup is characterized by a small detection spot and only by a slight weakening of the heat radiation inside the scanner. Hence, for welding PA6-GF30, the detection of small sized gaps is possible, even if a glass fiber content of 30 percent (wt.) and a weld seam width with approximately 1 mm are given.</abstract>

    <title language="eng">Simulation of Quasi-Simultaneous Laser Transmission Welding of Plastics</title>
    <abstract language="eng">Thermo-mechanical simulation offers great opportunities to optimize welding processes of plastics. For realistic simulation, the temperature dependent mechanical properties need to be implemented from ambient temperature to temperatures above the flow temperature. Standard test methods are insufficient for characterization in the entire temperature range because close to the flow temperature the material is too soft for tensile tests and too stiff for rheometry. Therefore, an optimization strategy is developed, that determines unknown material parameters by testing in welding simulations. The unknown parameters are iteratively adjusted to minimize the mismatch between computed and measured set-paths. Thus, important process characteristics are calculated realistically, enabling the computer aided assessment of the weld quality.</abstract>

    <title language="eng">Measurement of Core Temperature through Semi-Transparent Polyamide 6 using Scanner-Integrated Pyrometer in Laser Welding</title>
    <abstract language="eng">Predicting the core temperature during welding is an ambitious aim in many research works. In this work, a 3D-scanner with integrated pyrometer is characterized and used to measure the temperature during quasi-simultaneous laser transmission welding of polyamide 6. However, due to welding in an overlap configuration, the heat radiation emitted from the joining zone of a laser transmission weld has to pass through the upper polymer, which is itself a semi-transparent emitter. Therefore, the spectral filtering of the heat radiation in the upper polymer is taken into account by calibrating the pyrometer for the measurement task. Thermal process simulations are performed to compare the temperature field with the measured temperature signal. The absorption coefficients of the polymers are measured, in order to get precise results from the computation. The temperature signals during welding are in good agreement with the computed mean temperature inside the detection spot, located in the joining area. This is also true for varying laser power, laser beam diameter and the carbon black content in the lower polymer. Both, the computed mean temperature and the temperature signal are representing the core temperature. In order to evaluate the spatial sensitivity of the measurement system, the emitted heat radiation from both polymers is calculated on basis of the computed temperature field. Hereby it is found, that more than 90 percent of the detected heat radiation comes from the joining area, which is a crucial information for contact-free temperature measurement tasks on semi-transparent polymers.</abstract>

    <title language="eng">Correlation between Joint Strength and Process Temperature in Quasi-Simultaneous Laser Transmission Welding of Polyamide 6</title>
    <abstract language="eng">The joint strength is gaining importance in quasi -simultaneous laser transmission welds, especially in structural components. A correlation between the joint strength and a process characteristic is a basic requirement for selecting the best process parameter setting. In this work, the temperature is measured during welding polyamide 6 by using a scanner-integrated pyrometer with an InGaAs-detector. The filtering of the heat radiation in the upper joining partner is taken into account by calibrating the mea surement system. By this, the measured temperature signal represents the temperature in the joining zone. A correlation is found between the measured temperature and the  resulting joint strength. Moreover, high joint strengths are also seen for welds with short welding times, as far as the temperature is sufficiently high. With this knowledge, a process window can be derived easily in order to produce welds with high strength and short welding times.</abstract>

    <title language="deu">Festigkeits- und zeitoptimierte Prozessführung beim quasi-simultanen Laser-Durchstrahlschweißen</title>
    <abstract language="deu">Mit Blick auf Leichtbauanwendungen ist der Bedarf an thermoplastischen Strukturbauteilen sowohl in der Automobil- als auch in der Luftfahrtindustrie in den letzten Jahren deutlich angestiegen. Das quasi-simultane Laser-Durchstrahlschweißen ist ein etabliertes Kunststoffschweißverfahren, welches jedoch zur Herstellung von tragenden und sicherheitsrelevanten Bauteilen bislang kaum in Betracht gezogen wird. In der vorliegenden Arbeit wird die Korrelation zwischen dem Prozessablauf und der Schweißnahtfestigkeit beim quasi-simultanen Laser-Durchstrahlschweißen von Polyamid 6 (Ultramid B3s) erstmalig untersucht. Zur Prozessanalyse wird ein 3D-Scanner mit integriertem Pyrometer realisiert und für die Messaufgabe kalibriert. Es wird gezeigt, dass die detektierte Wärmestrahlung dem Kern der Schweißnaht zuzuordnen ist. Die Kerntemperatur in der quasi-stationären Prozessphase steht in direkter Korrelation mit der Schweißnahtfestigkeit. Mit steigender Kerntemperatur bzw. Molekülbeweglichkeit erhöht sich die Wahrscheinlichkeit der Bildung von Molekül-Verschlaufungen in der Fügeebene. Zur Ermittlung der Kerntemperatur ist sowohl die in dieser Arbeit entwickelte Temperaturmesstechnik als auch die realisierte numerische Prozesssimulation nutzbar. Die Erkenntnisse in dieser Arbeit sind für eine festigkeits- und zeitoptimierten Prozessführung des quasi-simultanen Laser-Durchstrahlschweißens nutzbar.</abstract>
    <abstract language="eng">The demand on thermoplastic components for lightweight constructions is continuously rising in the automotive as well as in the aerospace industry. The quasi-simultaneous laser transmission welding is an established joining technique in industry, but so far, it is usually not used for high strength applications as well as for safety-relevant components. This is caused by the lack of process understanding in case of producing high strength joints. Especially the temperature in the joining zone is a crucial process characteristic. Up to now, it was not measured in the needed precision. The quasi-simultaneous laser transmission welding of polyamide 6, especially the correlation between process characteristics and the joint strength is analyzed in this work. Therefore, a 3D-scanner with integrated pyrometer was realized and calibrated for the measurement task. It is shown, that the detected heat radiation is mainly coming from the core of the weld seam. The core temperature in the quasi-stationary process state is in direct correlation with the joint strength. The core temperature represents the mobility of the macromolecules in the polymer. An increased mobility leads to a better diffusion, relaxation or retardation of the macromolecules across the joining interface. A process window is defined on basis of the core temperature. The process setting which leads to a high joint strength as well as to the shortest irradiation time is found on the upper corner of the process window. The temperature can be measured with the needed precision by using the herein shown 3D-scanner with integrated pyrometer as well as by using the developed numerical process model. In conclusion, these tools for process diagnostics and the results of this work are useful for the production of welds with high joint strength and short welding times.</abstract>
