Fiber Laser Welding of Automotive Seat Rails and Constructions

Fiber laser welding is deployed in various industries to help with forms of manufacturing that can benefit from the accuracy, repeatability and efficiency that it offers when compared with traditional welding methods.

In an automotive context, fiber lasers can be used at several different stages throughout the process of producing key components for each vehicle as it moves along the assembly line. From car batteries for cutting edge zero-emissions models to differential gears and other precision parts, fiber laser welding is increasingly common as a tool for major automakers to harness.

This type of welding can also be integral to the installation of seat rails in modern vehicles, as well as a host of other structural elements that make cars safe and stable. Here is a look at how fiber lasers are changing the game in this competitive arena at the moment.

Fiber Laser Welding of Automotive Seat Rails and Constructions

Dissimilar material welding

There are various market pressures exerted upon the design of automotive seat rails and the seats which are attached to them. Manufacturers want to make these constructions as light as possible to boost fuel efficiency while also ensuring that no compromises to safety are made to achieve this.

As a result, seats and rails are typically produced using a variety of materials, including a combination of super-sturdy steels and other light yet strong alloys. Welding dissimilar materials can be a challenge, yet it is one which fiber laser welding solutions can take on with ease. Even metals which are too conductive or reflective for other forms of welding to be effective can be manipulated with fiber lasers.

This is achieved because of the added degree of control over the heat input that is available, as well as the fact that an incredibly compact melt zone can be specified to minimise waste and damage to the surrounding material. As many of the metals involved are incredibly thin, damage reduction clearly has a key role to play in ensuring the structural integrity is up to scratch.

Efficient manufacturing potential

Older welding techniques were essential to automotive manufacturing for decades, but their unwieldy, inefficient nature has imposed limits on what they can be used for. This means that to fulfill the ambitious designs of contemporary engineering experts, fiber laser welding is the only way to go.

It can not only cut energy costs but also offer improved flexibility in terms of the way that welding solutions are mounted. Remote, robotic systems can be configured to carry out complex welding routines, repeated almost endlessly with little need for maintenance across the installation of seat rails and other parts.

With all this in mind, it is easy to see why fiber laser welding is just one of the applications of this technology that is now indispensable to various manufacturing sectors.
