High-power laser welding of thick steel-aluminum dissimilar joints

Lahdo, Rabi; Springer, André; Pfeifer, Ronny; Kaierle, Stefan; Overmeyer, Ludger (Amsterdam : Elsevier B.V., 2016)

According to the Intergovernmental Panel on Climate Change (IPCC), a worldwide reduction of CO2-emissions is indispensable to avoid global warming. Besides the automotive sector, lightweight construction is also of high ...
Improving weld bead homogeneity in short arc GMAW processes applying low power diode lasers

Leschke, Jan; Zokoll, Erik; Hermsdorf, Jörg; Kaierle, Stefan (Amsterdam : Elsevier B.V., 2018)

Using laser and arc power in equal parts, laser-arc hybrid welding processes are successfully adapted by the industry. This paper shows the stabilizing effects of diode lasers on short arc GMAW (gas metal arc welding) which ...
Influence of the ultrasonic vibration amplitude on the melt pool dynamics and the weld shape of laser beam welded EN AW-6082 utilizing a new excitation system for laser beam welding

Ohrdes, H.; Nothdurft, S.; Nowroth, C.; Grajczak, J.; Twiefel, J.; Hermsdorf, J.; Kaierle, S.; Wallaschek, J. (Berlin : Springer, 2021)

Laser beam welding is a commonly used technology for joining similar and dissimilar materials. In order to improve the mechanical properties of the weld, the introduction of ultrasonic vibration into the weld zone has been ...
Influence of ultrasound on pore and crack formation in laser beam welding of nickel-base alloy round bars

Grajczak, Jan; Nowroth, Christian; Nothdurft, Sarah; Hermsdorf, Jörg; Twiefel, Jens; Wallaschek, Jörg; Kaierle, Stefan (Basel : MDPI AG, 2020)

Welding by laser beam is a method for creating deep and narrow welds with low influence on the surrounding material. Nevertheless, the microstructure and mechanical properties change, and highly alloyed materials are prone ...
Investigation of the composite strength of hybrid steel-steel semi-finished products manufactured by laser beam welding and friction welding

Behrens, Bernd-Arno; Chugreev, A.; Matthias, T.; Nothdurft, S.; Hermsdorf, J.; Kaierle, Stefan; Ohrdes, H.; Twiefel, J.; Wallaschek, J.; Mildebrath, M.; Hassel, T. (Bristol : IOP Publishing Ltd., 2018)

An ever-increasing demand for more effective products with lower weight, more compact design and extended functionality has led to the use of material combinations with locally adapted properties instead of mono-materials. ...
Investigations on laser beam welding dissimilar material combinations of austenitic high manganese (FeMn) and ferrite steels

Behm, Velten; Höfemann, Matthias; Hatscher, Ansgar; Springer, André; Kaierle, Stefan; Hein, David; Otto, Manuel; Overmeyer, Ludger (Amsterdam : Elsevier B.V., 2014)

For the past few years the customer's demand for more fuel efficient and at the same time safer vehicles has steadily increased. Consequently, light weight design has become one of the main interests in engineering. With ...
Investigations on laser beam welding of different dissimilar joints of steel and aluminum alloys for automotive lightweight construction

Seffer, Oliver; Pfeifer, Ronny; Springer, André; Kaierle, Stefan (Amsterdam : Elsevier B.V., 2016)

Due to the enormous potential of weight saving, and the consequential reduction of pollutant emissions, the use of hybrid components made of steel and aluminum alloys is increasing steadily, especially concerning automotive ...
Optical coherence tomography for laser transmission joining processes in polymers and semiconductors

Meyer, Heiko; Zabic, Miroslav; Kaierle, Stefan; Ripken, Tammo (Amsterdam : Elsevier B.V., 2018)

Laser transmission welding applications become wide spread technology in joining transparent and turbid materials. The requirement of higher throughputs and lesser rejects support the need of alternative methods to commonly ...
Reliable copper spot welding with ir laser radiation through short prepulsing

Moalem, A.; Von Witzendorff, Philipp; Stute, U.; Overmeyer, Ludger (Amsterdam : Elsevier B.V., 2012)

We demonstrate a technique, which significantly enhances the stability of copper welding with laser radiation. After modelling spot welding stability we conclude that oxide layer morphology typical for native oxide layers ...
Studies on the robustness of underwater laser cutting of S355J2+N using a Yb:YAG disk laser source

Leschke, Jan; Barroi, Alexander; Kaierle, Stefan; Hermsdorf, Jörg; Overmeyer, Ludger (Amsterdam : Elsevier B.V., 2016)

In this paper, an underwater laser cutting process for maintenance and replacement operations is presented and investigated regarding process robustness for the application in rough environments. A Yb:YAG laser is used ...
Temperature distribution during laser based heat conduction welding of CFRP

Wippo, V.; Winter, Y.; Jaeschke, P.; Suttmann, O.; Kaierle, Stefan; Overmeyer, Ludger (Amsterdam : Elsevier B.V., 2018)

For the implementation of carbon fiber reinforced (CFRP) parts, these need to be assembled to more complex structures. Therefore, laser transmission welding was transferred to heat conduction welding for joining thermoplastic ...
The influence of laser welding processes on the weld seam quality of thermoplastic composites with high moisture content

Wippo, V.; Winter, Y.; Jaeschke, P.; Suttmann, O.; Overmeyer, L. (Amsterdam : Elsevier B.V., 2016)

Presently, fiber reinforced materials are used for many industrial applications. Laser transmission welding (LTW) is a suitable method to join these materials. For multiple thermoplastics, the weld seam quality is affected ...
