New Trends and Technologies for Laser Processing and Control

2 December 2021
Online via MS Teams

Industrial laser processing is faced with a lot of new technology and many new possibilities these years. This entails that more parts can benefit from being manufactured by laser processes, and existing laser equipment can be upgraded to perform with higher efficiency and robustness. Additionally, integration with the manufacturing system, quality monitoring and control, digital solutions and Industry 4.0 are themes to be aware of in manufacturing with lasers.

This seminar will give you a technical overview of trends and technologies to watch for when working with industrial laser processes.

13:00 - 13:10
Welcome and introduction by Morten Kristiansen, Associate Professor, Aalborg University
13:10 - 13:45
New innovations in sheet metal processing with laser radiation - increasing quality in cutting and welding through process control

Markus Kogel-Hollacher, Head of of Department R&D Projects, Precitec

As laser is now a conventional tool, the main topic in production today is headlined with the words digitization, artificial intelligence and Industry 4.0. Especially in this context sensor technology is a leading part related to Smart Factory and predictive maintenance and even process control. Transforming machine elements into intelligent cyber physical systems involve the integration of smart sensors for condition and process monitoring.

One of the key modules between the laser source and the work-piece are the beam shaping optics, in everyday language the processing head. As in the past, the bulk material of the optical elements or the increasing brightness of the laser sources took center stage, the attention now moved to solutions where the intensity distribution at the work-piece surface and inside the work-piece is designed with the explicit knowledge of beam material interaction.

This contribution to the seminar will try to demonstrate the recent technical innovations developed in-house. These new features in the area of laser cutting and welding will be described technically and the benefits of these devices will be presented.

Laser beam welding improvement thanks to beam-shaping with multi-plane light conversion technology

Gwenn Pallier, Product Line Manager for material processing applications, Cailabs

The development of lasers with higher available power pave the way to more complex laser-based welding, such as gap-welding, or thicker parts welding. Nevertheless, the available laser-heads are based on refractive optics, which highly limit the capability to fully use the available power. Indeed, most laser-heads are not capable of handling such powers, and when they are it implies cm-scale focus shift, leading to a reduced robustness of the process.

During this seminar, the performance of a laser-head based on Multi-Plane Light Conversion (MPLC), a fully reflective technology, will be described. The laser-head provides an annular shape at 1µm. It stabilizes the keyhole even at high power with a less than a 1mm focus shift. You will learn here why this laser-head can improve your Laser Beam Welding process with an example on 304L stainless steel welding. The ease of integration of the laser-head on a standard robot arm will be shown. At last, we will discuss on more complex use of this laser-head, including hybrid welding.

Gwenn Pallier holds a MSc in optical engineering from the Institute of Optics (Paris, France). As project and product line manager at Cailabs, she brings her expertise to the development and commercialization of innovative optical solutions that optimize the quality and performance of laser-based material processes.

Laser forming of sheet metal

Anders Noel Thomsen, Postdoc, Aalborg University

Laser forming is a new and interesting incremental forming technology that uses a laser to form shapes without external forces applied. The process does not rely on part specific tools and dies, which makes it ideal for customized production and prototyping. Current research at Aalborg University is aimed at fully automating the process, reducing the need for highly trained workers and long run-in times. This presentation will discuss the current research at AAU, how the process works, including current and future cases where this technology could be applied.

Anders is a Postdoc at Aalborg University working on the topic of Laser Forming. He successfully defended his PhD in 2020 titled “Laser Forming of Sheet Metal”.

Technologies for laser processing of sheet metal

Morten Kristiansen, Associate Professor, Aalborg University

Manufacturing of sheet metal components can be done by a wide range of laser technologies. This presentation will show how to combine laser technologies and how it is applicable for industrial use in an Industry 4.0 system for laser processing. Additionally, many laser processes can be improved by beam shaping methods. A beam shaping technique will be presented and industrial cases of its use will also be shown.

Morten Kristiansen is Associate Professor at Department of Materials and Production, Aalborg University. He works with automation of industrial processes and has for more than 10 years been focussing on laser processes.
