Meet LWT in Barcelona

LWT will show samples of Laser Hybrid Welding at the EWEA 2014 exhibition in Barcelona, 10th – 13th of March

EWEA is Europe’s premier wind energy event and presents an international platform for the wind energy industry to showcase and demonstrate its latest products and services.
LWT will be present on FORCE Technology’s exhibition stand no. 7E50 where we will show samples of Laser Hybrid Welding in 12 mm, 25 mm and 40 mm sheet thickness.

Laser Hybrid Welding in the wind energy industry is targeting welding optimization for foundation and tower manufacturing. LWT and the Laser Hybrid Welding technology offers:
  • State-of-the-art laser facility, 32 kW Laser Power
  • Welding of large sheet thicknesses in only a few passes
  • Low heat input compared to SAW (less distortion)
  • High welding speed (high productivity)
  • Excellent mechanical properties
  • Industrially applicable welding method 
See you at stand no. 7E50

LWT generates interest among metallurgists 

A demonstration of the very powerful laser hybrid welding technology generated great interest among participants when Danish metallurgists visited LWT. 

LWT performed a live demonstration of laser hybrid welding in 40 mm plate thickness with the 32 kW laser facility. The possibility to weld large plate thicknesses with few weld passes and a low heat input generated great interest among the participants from the Danish Metallurgical Society (DMS). LWT was hosting the DMS winter meeting.

The 32 visitors represented a wide range of the Danish industry and were mainly specialists, engineers and technicians with a background in materials and technology. As part of the meeting they visited Lindø Industrial Park. The visit started with general presentations of the industrial park, LORC, LWT and of the plans to build a component and substructure test centre.

The program also included a visit to LORC’s facility to see the ongoing construction of the 10 MW nacelle testing facility’s large motor with a torque of 12 million Nm at 10 RPM.

LWT hosts Production in Denmark meeting

20 members of the newly started ‘Production in Denmark’ met at LWT and had a unique opportunity to see the 32 kW laser welding system in action.

‘Production in Denmark’ is a three year project founded by the Danish Agency for Science Technology and Innovation with with the vision to strengthen small and midsized companies in Danish industry by implementing well-known technology. The project focuses on six different areas, but the networking meeting hosted by LWT was all about the potential in laser technology.

The 20 participants represented a broad variety of companies and the choice of LWT as host gave them a unique opportunity to see the 32 kW laser installation and experience a live demonstration of Laser Hybrid Welding. The visitors expressed great interest in the possibilities of boosting productivity and quality by implementing laser technology.

Day of celebration – the official opening of LWT 

January 28th 2013 was day 1 in the history of LWT – the open fabrication lab for advanced laser welding technology. The day was celebrated by a ceremonial cutting of a traditional welding wire which symbolically blocked the entrance to the safety steel fence encircling the laser-armed robotic arm. The golden bolt cutter to cut the wire was handled by the Danish Minister of Housing, Urban and Rural Affairs, Carsten Hansen, and witnessed by the former Prime Minister Poul Nyrup Rasmussen and by Mads Lebech, CEO of Industriens Fond, a significant sponsor.

More than a hundred persons including visitors, partners, suppliers and potential customers joined the event along with local politicians, union leaders and academic representatives.  The speakers generally agreed that the creation of LWT in a line of planned technology service centers from LORC is symbolic for a bigger picture - the cross-industrial move towards a strategic building of new technologies for the future.

The laser-system was this day – for the sake of the visitors – programmed to move in a safe demonstration mode with the laser-beam switched off. A common red laser-pointer was mounted and used to illustrate the movements of the laser-head over inch-thick steel plates.



Ernst Tiedemann, CEO of FORCE Technology – one of the two founders of LWT - spoke about the importance of the new laser technology which is a continuation of many years of welding research and development at FORCE Technology.

The first of two 16 kW lasers arrives at LWT

Two tons of laser equipment is now unloaded on the floor of LWT. Power and cooling water is connected and technicians from Trumpf have started the calibration process. Meanwhile the next half of the laser system is being prepared for delivery at Trumpf.
