Interview

“Industry 4.0: Benefit From Opportunities. Today. Tomorrow.”

Getting not only industrial processes ready for Industry 4.0 but also peripherals in the infrastructure, is obtaining increased attention – especially at the major industry fairs. As Teka was presenting its new Airtracker Mini (cf. p. 36) – which will also be featured at the Blechexpo – we took the opportunity to visit the Teka booth at the Schweissen & Schneiden in September.

Additive Manufacturing

Powder on Demand

The use of a Rapid‐Powder‐Switch (RPS) during laser metal deposition leads to powder savings of up to fifty percent: With a short switching cycle of less than 200 ms, the powder is immediately available between processing cycles. Thus, surfaces can be coated precisely and only where required – efficient and resource‐conserving.

Laser Cladding

Laser Surface Cladding of Titanium Aluminides

Laser powder cladding is considered the best available technology for the repair of components from power plant turbines and aviation engine components. With the technical milestone of introducing a new group of materials – the titanium aluminides (in short TiAl) – in the aircraft engine, new requirements of technical / technological challenges need to be met.

Process Control

Acoustic Process Control for Laser Material Processing

Listening to an industrial process can reveal relevant information. As a complementary approach to optical process surveillance, monitoring the acoustic emissions is a promising alternative. Yet, acoustic detectors have not been extensively established in process control, one reason being their limited frequency bandwidth. Overcoming the disadvantages of existing microphones, a novel laser‐based acoustic sensor opens new...

Fiber Optics

CO 2 Laser‐Based Fiber Splicing System

The outstanding spatial and temporal flexibility and precise control of a laser beam enable automated, reliable and individualized production of single‐ and multi‐mode fiber components. These components can be used for fiber lasers and amplifiers, fiber‐coupled diode lasers and fiber‐based beam delivery systems. The cost‐efficient customization of fiber components is important for the support of the wide range of laser...

Additive Manufacturing

The Incredible Additive Manufacturing Creates Movement

At first glance, additive manufacturing seems to be a very simple manufacturing process. Nevertheless, many companies are not happy with their adaption of this new technology or are even overburdened by it. Often, we have to undisputedly agree with these companies. However, we can change their opinions straight away. The fascinating metal 3D printing nowadays even manages to print moving objects without needing assembly...

3D Micro‐Printing Goes Macro

In 1997, Satoshi Kawata and his colleagues from the Osaka University in Japan introduced a revolutionary method for three‐dimensional microfabrication based on two‐photon polymerization (2PP) [1]. Today, this 3D direct laser writing technique allows for building nano‐, micro‐ and millimeter‐sized objects of almost any desired shape with easy processes along a classical 3D printing workflow. 2PP uses photopolymerizable...

Application Report

Laser Welding: FusionLine Closes the Gap

One of Trumpf's goals at the Schweißen & Schneiden welding trade fair in Düsseldorf was to demonstrate how lasers can facilitate the welding process. Laser welding may not be able to replace every MAG weld seam, but it offers plenty of advantages in the cases where it can. The ongoing trend towards greater product customization poses a challenge to companies as they seek ways to produce small batches more efficiently....

Prevention, Lived Digitally

Industry 4.0 is also a widely discussed topic on the laser market. Whereas the digitalization of the working environment related to Industry 4.0 is widely discussed among experts, it has not yet made it into the reality of many small and medium‐sized businesses. Too aloof, too expensive – these are the fears of many companies. Even though easy to operate digitized solutions can put the prevention at the workplace in...

New Process for Narrow Pipes

The greatest challenge in many processes is not the question of “How” but of “How long”. All too often, tool breakage or damage leads to unplanned production stops.

When Robot Precision Becomes a Decisive Competitive Advantage

More than forty employees are engaged in the design and construction of welding systems at Conntronic Prozess‐ und Automatisierungstechnik GmbH. In its almost 15‐year‐old history, the company has built up numerous core competencies. These include CD machines and systems, special systems on the basis of resistance welding technology or robot‐driven laser welding and cutting systems.

Einführung in die Simulation von Halbleiter-Bauelementen

  • 30. November 2017

Von Mosfets über LEDs bis zu Wafern – Halb­leiter­bau­elemente sind essen­tielle Bestand­teile moderner Tech­nik in nahezu allen Bran­chen. Die nume­ri­sche Simu­la­tion kann dabei ein wich­ti­ges Hilfs­mit­tel dar­stel­len, um diese Bau­elemen­te in ihrer Funk­tions­weise zu analy­sie­ren und somit deren Kon­zep­tion zu er­leich­tern.
