Remote Laser Welding

Admin — Fri, 04 Dec 2015 08:57:38 +0000

An alternative to the proven and reliable technique of resistance spot welding (RSW) is remote laser welding (RLW). It offers a number of advantages such as creating joints in different locations on the product through simple robot repositioning, only needing the application of the laser beam to one side of the part, and its ability to achieve process speeds up to five times faster than spot welding. The main reason why RLW has not been adopted more widely is the lack of methodologies for precise and effective planning and simulation of its application. More

Hydroforming Techniques

Lightweight vehicles are big news in the automotive industry at the moment, following the launch of the ultralight steel. Lighter vehicles offer the benefits of materials and energy savings, and so are more environmentally friendly. But weight cannot be trimmed from a car without design changes, which is why new ways of producing lightweight steel components - and of reducing the total number of components - are vital for the future.

Rather than printing the entire body shell of the vehicle out of a rigid composite material, as startup Local Motors is doing with its 3D-printed cars, EDAG instead created a lightweight metal structure optimized to use material only where absolutely necessary. More

New high-strength, room-temperature-formable steels

Admin — Fri, 04 Dec 2015 08:31:20 +0000

Many of the critical elements of a vehicle’s crash structure such as the B-pillars and frame rails are often made of a high-strength steel (HSS) called press-hardened boron steel. This specialized steel grade (with 0.002% to 0.005% boron) is especially good at absorbing large amounts of impact energy and offers strength levels that allow design engineers to use thinner sections and thus save weight. more

Laser Assisted Forming Techniques

Admin — Fri, 04 Dec 2015 08:22:22 +0000

During forming processes high deformations rates can lead to cracks and rupture very easily. Especially brittle materials like titanium or magnesium make difficulties in forming. Due to the dependence of the yield strength on temperature, forming at elevated temperatures eases processing of such materials. Since forming takes place only at localized areas of the work piece selective heating is sufficient and advantageous in most cases. Selective Laser heating offers a possibility to heat only the areas of the work piece where strongest deformations are required. more
