BAM study by Michael Rethmeier says: Laser welding in car body construction is more ecological that resistance-spot welding.
Taiwan’s economic miracle is also a laser miracle. Dr. Fanghei Tsau, General Director of the Laser & Additive Manufacturing Technology Center at the ITRI, and his team is at the forefront.
Where weld seams have to be durable but also practically invisible, the automotive industry opts for laser brazing – and in the future, this will apply to hot-dip galvanized sheet metal, too. Laser brazing is presented below.
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.
Dr. Antonio Candel-Ruiz explains why laser metal deposition is evolving into an additive manufacturing technique in its own right, and how even small and medium-sized businesses can benefit from the technology.
Oliver Schauerte, head of materials research and manufacturing processes at the Volkswagen Group, discusses the latest trends in lightweight construction, gun licenses for production staff, and the next big thing among materials.
Automotive giant GKN Driveline started welding drive components with lasers 14 years ago. Now the tried-and-tested system is moving to the next round — featuring disk lasers — on three continents.
Researchers from TRUMPF, Bosch and the University of Jena won the Federal President's German Future Prize 2013. The team cleard the way into mass manufacturing for ultrashort pulse lasers.
Induction is proving to be an ideal partner for laser welding: for pre-heating, cleaning and hardening
To make electric drives affordable, we need to work out details such as how to produce millions of laminated cores cost-efficiently.
A look inside the multi-faceted future of hybrid laser welding.
The wobble method is taking the automotive industry by storm. It offers all the advantages of remote welding, plus it bridges gaps between the surfaces being joined. That cuts down on costs and above all weight.
The boom in high-strength steels triggered a second boom — in job shops able to cut them. In Mexico, Gerardo Oaxaca was one of the people who forged his own success.
Gentle, non-contacting laser systems create a stir in surface finishing: A collection of practical applications from BMW to archeology
For all the usefulness of coatings, they can be an impediment when welding. Which is where the cleaning power of short-pulse lasers comes in.
New concepts in the design and construction of structural elements of the car body save weight, time, costs and installation space.
The next generation of scanner optics will release the focus spot from the working plane. Here’s how users will benefit from this three-dimensional dance.
A small part makes a huge difference: the gasket silencer from KACO has put an end to loud water pumps
The car of the future should still be fast, comfortable, safe and able to go the distance. The car of the future should have very low CO2 emissions. But how?
The road to fiber-reinforced plastics in mass production is via the laser, says Dr. Uwe Stute, who reviews the opportunities and challenges ahead.
What is so special about the third dimension ? And how do you work through a 350,000-part series ? Erhard Hujer is the man who knows
GM decides to contract out a central aluminum part of its SUVs and pickups. Van Rob decides to redevelop the part in steel
