GM vehicle recalls due to laser welding machine

29 July 2014

General Motors today announced six safety recalls covering 717,949 recent model vehicles in the U.S. A total of 124,007 are being recalled due to an issue with one of the company’s laser welding machines.

The faults, the company said in a press release, are due to a loss of power to a laser welding machine according to data collected between July 2013 and January 2014. The vehicles are being recalled to dealers to inspect a possibly incomplete weld on the seat hook bracket assembly.

Diode laser that can cut half inch steel commercialised

28 July 2014

TeraDiode, an MIT Lincoln Laboratory spin out company, is commercialising a diode laser system that can cut through half an inch of steel while still benefitting from diode laser's increased efficiency when compared to other laser types. Until now, systems manufacturers have struggled to keep beams from diode lasers bright enough to cut such materials.

The 4kW TeraBlade uses a power-scaling technique developed at MIT that manipulates individual diode laser beams into a single output ray. This allows for boosting power of a diode laser, while preserving a focused beam.

First photonics technology report on automotive industry

24 July 2014

The first market report analysing the use of photonics in the automotive industry will be released in December 2014. The European Photonics Industry Consortium (EPIC) has partnered with market research company Tematys to produce the market technology report, which is expected to benefit developers of photonics technologies and sales and marketing personnel working in the field of photonics.

Quick and clean laser welding for thick metal sheets

22 July 2014

A new laser-based hybrid welding process developed at the Laser Zentrum Hannover (LZH) makes it possible to weld thick pipelines and metal sheets at greater speed, reducing process costs of liquid gas tanks and pipelines by lowering processing times. It is now possible to weld aluminium alloys or steel at speeds of 6m/min or 1.5m/min respectively.

Exhibition style anniversary party at Eurolaser

17 July 2014

To celebrate its 20th anniversary, Eurolaser is organising an in house technology fair to take place on 11-12 September in the company’s native Lüneburg, Germany. The exhibition will show the company’s partners latest innovations from a range of specialists that manufacture laser systems and components.

Eurolaser will present its latest analysis tool, Watchdog, to the public for the very first time. This live-monitoring tool enables customers to keep all key functions of their laser systems in view at all times.

Trumpf strengthens Eastern European position

Trumpf has strengthened its position within Hungary through the acquisition of the Lasersystems sales agency as the company continues to expand its presence in Central and Eastern Europe. The merger was announced just weeks after a number of managerial changes within the Trumpf group.

Maersk looks into on-ship 3D printing for tanker repair

14 July 2014

The shipping company Maersk has started looking into using additive manufacturing to replace faulty parts onboard its tankers.

The speed of production, readiness of a specific part and the reduction in cost of getting a replacement to tankers positioned all over the world have all played a part in the company's increased interest in 3D printing. While cost could still be prohibitive for metal parts - as the 3D printing machines are still far more expensive - the company and its partners have indicated they see the technology as nearly ready.

Trumpf bank aids steel processing company

11 July 2014

Trumpf Financial Services has provided funding to a steel processing company in order to buy one of Trumpf's laser systems. C. Brown & Sons was financed for a TruLaser 3040 CNC laser profiling system, which will be installed at its headquarters in Dudley, UK.

Large-area micro structuring system presented at Lasys

02 July 2014

Scientists at Fraunhofer IWS have presented a novel compact system for metal micro-structuring at the Lasys material processing trade fair in Stuttgart, Germany from 24-26 June.

The system is able to impart clever functions onto a material by patterning periodic structures onto its surface. This kind of surface structuring has applications in bio-materials, automotive, the fabrication of more efficient organic solar cells, and for anti-counterfeiting. The scientists presented examples of the structuring process at Lasys.
