Keyhole behaviour during laser welding of zinc-coated steel
The production of consistent, high-quality laser welds on zinc-coated steels for the automotive industry remains a challenge. A simple overlap joint geometry is desirable in these applications but has been shown to be extremely detrimental to laser welding because the zinc vapour formed at the interface between the two sheets expands into the keyhole and disrupts fluid flow in the melt pool, wh...
متن کاملLASER 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...
متن کاملLaser 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...
متن کاملLaser 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...
متن کاملTransport Phenomena and Keyhole Dynamics during Pulsed Laser Welding
Numerical and experimental studies were conducted to investigate the heat transfer, fluid flow, and keyhole dynamics during a pulsed keyhole laser welding. A comprehensive mathematical model has been developed. In the model, the continuum formulation was used to handle solid phase, liquid phase, and mushy zone during melting and solidification processes. The volume-of-fluid method was employed ...
