BAM study by Michael Rethmeier says: Laser welding in car body construction is more ecological that resistance-spot welding.
Weld joints and adhesive bonds in powertrain components must comply with strict quality standards. To obtain first-class results, the joining surfaces must be perfectly clean. Lasers are efficient cleaning tools, capable of removing all traces of oily residues.
Walter Sticht has been devising high-tech automations for the past 44 years. No laser systems ever passed muster with him – none of them suitable for automation. He has now changed his mind and is starting his latest enterprise.
Femtosecond laser pulses weld glass without any additional material. The process is economical and ready for industrial practice.
More and more cities around the globe are opting for electric buses made by BYD. One of the strengths of this Chinese company is its in-house expertise in high-performance batteries. Laser technology is used to weld their highly sensitive components.
Weighing 20 tons and up to 200 millimeters thick. The sheets TRUMPF welds in Austria are the biggest ever tackled by a hybrid laser welding head from Fronius International GmbH. The TRUMPF plant in Austria uses a fully automatic process to produce huge frames for press brakes.
Aluminum, CFRPs and plastics are tomorrow’s most promising candidates for lightweight design. But what plans and visions do their makers have ? Read on to find out.
First cut, then weld. At THE Machines lasers are used to ensure that the coil never ends.
A newly developed pulsed green laser welds copper with high reproducibility and little spatter – regardless of the nature of the surface.
Thin aluminum and copper tubes protect the optical fibers in submarine cables against huge volumes of water. Nexans welds the tubing using a diode laser – with a seam 100,000 meters long!
Dr. Shuang Liu (28) earned her doctorate in the laser processing of materials. We asked her what drew her to light.
Hypodermic needles are disposable products. With its clever tube forming process and diode lasers, Nexans is ensuring the needles doctors discard will soon be much more cost-effective.
Pro-beam, TRUMPF and the ifs are moving the process for the low-pressure, spatter-free laser welding of powertrain components into industrial application.
For joining coils, a machine made by Belgian company Malex switches flexibly between resistance welding and laser welding depending on the type of steel, and also uses the laser source for cutting.
