High-performance laser welding

LASER WELDING - Literature Review

Lasers are now being used in the automotive industry to produce seam or stitch welds, as alternatives to conventional resistance spot welding, which are used extensively for attaching auto-body panels to subassemblies. The advantages of laser welding over resistance spot welding result from the smallness of the laser spot size, the large penetration depth of the weld into the material and the r...

Laser Revolutionizes Industrial Welding

Special attention has been focused on creating an ergonomic operator station that is not intimidating. This guarantees fast and efficient work, without fatigue, for many hours. The operator sits in front of the welder and manually loads parts to be welded into the enclosure. The operator has a clear view of the processing area through a large laser-safe window of protective glass. The final pos...

Laser nerve welding

Microsurgial suture (Conventional microsurgical suture repair, CMSR) is the most commonly used method for anastomosis of severed peripheral nerves. Functional recovery after this type of repair is often inadequate, however, even though the peripheral nervous system has a remarkable ability to regenerate adequate sizes and numbers of axons. The most significant problems with microsuture repair a...

Hybrid Laser-Arc Welding

Laser welding of modern automotive high strength steels

The paper demonstrates the correlation between the chemical composition of steel grades and the hardness as well as the formability of laser welds generated with modern automotive high strength steel grades. At the very low heat input of industrial laser welding and the resulting extremely high cooling rate, the weld hardness is fully controlled by the carbon content of the base materials and n...
