Market Report

The Worldwide Market for Lasers

Over the last thirty years, new developments in laser systems have impacted strongly on every single aspect in the manufacturing of devices and products that are currently available on the market, for example, novel femtosecond laser solutions allow materials processing of practically any material with extremely high precision and minimal collateral damage (for example, the femtosecond lasers by EXPLA as the one depicted in...

Laser Welding

High Power, High Speed, High Quality

At the Institut für Strahlwerkzeuge (IFSW), laser beam welding of aluminum sheets with a laser power of 16 kW and feed rates up to 50 m/min was investigated. The resultant weld seams were virtually free of processing pores and fluctuations of the penetration depth. Welding at very high feed rates reduced centerline cracking in close edge positions and increased the process efficiency. Humping could be prevented by welding...

Laser Surface Processing

Laser Technology for Tool Production

In the course of the last twenty years, laser treatment of tools and dies has been transferred from a fundamental research work into an established technology of the modern manufacturing process. In the beginning, the focus was put on laser beam hardening. Nowadays, laser beam cladding is also increasingly accepted for repair and modification of tools or even completely new tool design. In principle, both technologies,...

Additive Manufacturing

Automated Manufacturing of Sensor‐Monitored Parts

Laser beam melting (LBM) is a powder bed‐based additive manufacturing technique, where metal powders are layerwise and selectively molten into complex geometries. LBM is state of the art in several industries, such as aerospace or medical for the production of metal parts. The automated integration of sensors and actuators during LBM exhibits great potential for manufacturing of function‐integrated metal parts. However,...

More Than Beam Profiling

With its unique design and fabrication possibilities, additive manufacturing (AM) is rapidly gaining relevance in a wide field of scientific and industrial applications. Especially when considering industrial exploitation, a sound knowledge and control of the influential factors dominating the process is crucial, to ensure constant quality. In addition to the properties of the laser spot as the actual tool processing the...

Tomorrow's Advanced Technology for Laser Welding – Today

Optical coherence tomography (OCT) becomes a widely accepted technique for precise and consistent seam‐guided laser welding. Being advantageous due to its operation principle, OCT has gained a role of innovative seam tracking technology for highly productive, cost‐effective laser processing. The industrial tests deliver satisfactory results. Either remote laser welding of body‐in‐white or gap bridging, OCT is an unbeatable...

Laser Cooling

Cooling Solutions for Laser Applications

In cutting, welding, and additive manufacturing, lasers are a universal tool. To make sure that a laser operates reliably, its components must be cooled as the generation of the laser light creates heat. If this heat is not discharged, both the laser and the workpiece will heat up. Heat can diminish the accuracy of the laser beam and even deform parts of the laser. To prevent temperature fluctuations and damages, laser...

Laser Welding

A “World Champion” in Energy Efficiency

In terms of efficiency, laser welding has long been a major contender. With the launch of a new generation of beam source and processes that bring improved productivity, Trumpf has now made it into a real champion.

Matching the Intensity of the Laser to the Speed

The performance of precision, multi‐axis positioning solutions for laser processing depends both on the mechanics and the drive type selected, and also its automation controller. For example, to achieve consistent path quality during laser cutting, the intensity of the laser and the speed of the moving components must be precisely matched to each other in order to cut as consistently as possible and in the shortest possible...

Application Report

Power Packs

Today, modern industry lasers are found in many fields of use, from automotive and heavy industry to tool making. As to the type of laser that applicants may opt for is mostly determined by factors such as output power, beam quality, investments, and operating costs. However, depending on the individual process requirements, these are by no means the only criteria for choosing an industry laser system.
