Fiber Lasers have multiple uses within the automotive industry due to the large number of benefits that they offer compared to more conventional manufacturing tools, such as having greater flexibility, superior quality, increased productivity and improved profitability. The rate at which fiber lasers are being adopted into industrial sectors such as the automotive industry is rapidly increasing year upon year.

Automotive applications and uses

The emerging market of e-mobility and electric cars is causing a rapid adoption of fiber lasers. Applications used include hairpin welding and stripping in electric motors as well as the cutting and removal of coating layers from battery foils.

Engraving and marking techniques are actively used for marking of parts and adding VIN and serial numbers, these can even be applied at microscopic levels and can be introduced into manufacturing workflows. Night & Day marking of dashboards is a particularly popular application.

Fiber laser welding is extensively used for applications such as airbag initiators, batteries and fuel injectors and is especially valuable in dissimilar metal welding processes.

As with other industries, Automotive has rapidly adopted 3D printing through additive manufacturing processes which allow the rapid printing of parts, tools and devices and also enable rapid prototyping which speeds up product R&D lead-times.

Cutting is extensively used in the industry for the high-precision cutting of parts, offering the cutting of complex, awkward and unusual shapes.

Drilling is similarly used for all types of drill holes, including more intricate ones such as the drilling of injection nozzles or even highly visible holes in metal speaker covers; found in some of the more expensive marques.

SPI Lasers and the automotive industry

SPI Lasers range of Continuous Wave (CW) and Pulsed fiber lasers already have a large number of automotive customers and it’s no surprise why given the diverse capabilities available.

Fiber lasers such as those from SPI operate across the entire spectrum of automotive companies. This is because of their versatility which enables them to be used in applications such as drilling, engraving and marking, which all change the appearance of a part. Where processes have to lead to dirt and grime accumulation techniques such as ablation and cleaning can be used to tidy up parts. For the more adventurous additive manufacturing can be used to 3D print parts and other automotive items. Fiber lasers also provide precision cutting and welding, which has a diverse range of applications in the industry and are growing in demand thanks to the expanding e-mobility market.

Listed below are automotive specific postcards and application insights, which we have specially prepared and we hope you enjoy.
