Laser Welding In Automotive

Laser Welding of Components of Automotive suppliers

Reducing costs and boosting quality are particularly important as part of the production of components within the automotive supplier industry. For instance, as part of axle, shock absorber, gear parts and powertrain parts, exhaust system, seat, and wheel production as well as many other components. In these areas, wobble laser welding anti-spatter behavior and low HAZ zone, can make a significant contribution to protection from enormous rework costs.

Wobble Laser Welding of components saves reworking costs and maintains the quality of metal surfaces.
Wobble laser welding prevent metal spatter on components — at linking points, threads, in visible areas — and in general help to obtain ideal corrosion protection. 

Wobble laser Welding saves cleaning costs, boosts service life, and prevents faults.
For instance, in axle production, it is widely used in MAG welding processes to use chemical covering layers., in gear part production it is used to put protection layers for protection of jigs. The use of wobble laser Welding increases the service life and the (dry ice) cleaning intervals, — simply put, it saves cost

Battery welding with Wobble laser welding machine

The increased application for lithium batteries in electric cars and many electronic devices means fiber laser welding is used in the product design. Components carrying electric current produced from copper or aluminum alloys join terminals using fiber laser welding to connect a series of cells in the battery.

Aluminum alloys, typically 3000 series, and pure copper are laser welded to create electrical contact to positive and negative battery terminals. The full range of materials and material combinations used in batteries that are candidates for the new fiber laser welding processes.

Overlap, butt and fillet-welded joints make the various connections within the battery. Laser welding of tab material to negative and positive terminals creates the pack’s electrical contact. The final cell-assembly welding step, seam sealing of the aluminum cans, creates a barrier for the internal electrolyte.

Because the battery is expected to operate reliably for 10 or more years, these laser welds are consistently high quality. The bottom line: With the correct fiber laser welding equipment and process, laser welding is proven to consistently produce high-quality welds in 3000 series aluminum alloys that have connections within dissimilar metal joints.
