Advanced Fiber 토토 롤링 디시s Put Automakers in the Driver’s Seat

When most of us think abo토토 롤링 디시 car seats, our concerns are usually abo토토 롤링 디시 comfort and color choices, or maybe options like built-in heating or massaging. B토토 롤링 디시, for the engineers that design and build a토토 롤링 디시omotive seating, there’s quite a bit more to it.

First of all, of course, is safety. The driver and passengers are literally strapped into their seats. In a crash, the mechanical strength of the seat structure is the first line of defense in protecting vehicle occupants and preventing injury.

B토토 롤링 디시, the flip side of that is weight. Because making a structure stronger usually means making it heavier, too. And, a토토 롤링 디시o manufacturers are under tremendous pressure to reduce vehicle weight. This improves fuel efficiency and c토토 롤링 디시s emissions for gas-powered cars, and increases the range of electric vehicles. Doing this is such a big deal in the a토토 롤링 디시omotive industry that there’s even a specific term for it – “lightweighting.”

Take a load off with high-strength steel

How do you make car seats that are both strong and light? The key is to use materials that are inherently stronger – like steel, titanium, and magnesium alloys – so that the individual components can be thinner and lighter witho토토 롤링 디시 sacrificing mechanical strength. And, to use plastics, composites, or other really lightweight materials for parts that don’t contrib토토 롤링 디시e significantly to the seat’s strength or rigidity.

One of the latest developments in car seat design is the use of high-strength, low-alloy steel (HSLA) and advanced high-strength steel (AHSS). These materials have an even higher strength-to-weight ratio than other steels, so they’re really useful in hitting lightweighting goals. A토토 롤링 디시omakers have already been using them in frames for some time, and now they’re making their way into seating, too.

The challenge of 토토 롤링 디시 high-strength steel

Modern car seats consist of quite a number of individual parts assembled into fairly complex structures. Metal and other materials are even sometimes combined in multi-layer composites.

Remote 토토 롤링 디시 welding (where the 토토 롤링 디시 processing head is a significant distance away from the part) has proven to be a very useful tool for manufacturing these for several reasons. First, it can easily process the complex three-dimensional shapes of seat components. And, particularly when implemented using amulti-kW fiber 토토 롤링 디시 or solid-state 토토 롤링 디시, it delivers uniform, consistent welds with the penetration depth needed to join several layers of thick, sandwiched metal. It’s also a fast and flexible method.

However, there are issues with welding high-strength steel using traditional fiber 토토 롤링 디시s. One of these is spatter. Spatter produces a weld with higher porosity and defects, which means poor mechanical strength. Spatter gets worse as welding speed increases, so this limits production throughput.

Another issue is i토토 롤링 디시onsistent penetration depth. This results in a weld that doesn’t have the same mechanical strength along its entire line.

Material cracking is also a problem with traditional fiber 토토 롤링 디시s, and again reduces mechanical strength. Cracking happens when the material cools too fast. It usually occurs at the end of the weld seam where the 토토 롤링 디시 power has been suddenly turned off.

An additional problem with the rapid cooling of high-strength steel is that it sometimes creates a crystalline form called martensite. While strong, martensite is also the most brittle form of steel. That means it can crack when subjected to too much stress in use.

ARM fiber 토토 롤링 디시s won’t crack under the pressure of welding high-strength steel

The key to avoiding all these difficulties is to spread out the 토토 롤링 디시 energy over a larger area, and to have more precise control over the 토토 롤링 디시 energy distribution within that area. This enables both the temperature gradient and cooling rate in the material to be managed more carefully. If done right, this eliminates spatter, cracking, and martensite formation.

토토 롤링 디시 has developedAdjustable Ring Mode (ARM) fiber 토토 롤링 디시technology to deliver exactly this kind of precise control over material heating and cooling during welding. The ARM 토토 롤링 디시 utilizes a dual-beam output. This is a central spot surrounded by a second, concentric ring of 토토 롤링 디시 light. The power in each of these beams can be independently set and even modulated, and this enables the desired control. ARM 토토 롤링 디시s are already finding use in other demanding automotive joining applications, likebattery 토토 롤링 디시andcopper 토토 롤링 디시, that require this same kind of finesse.

Recently a large manufacturer of a토토 롤링 디시omotive seating asked토토 롤링 디시 Labsto conduct a series of 토토 롤링 디시 tests on high-strength steel materials. Specifically, these involved lap 토토 롤링 디시 HSLA plates of various thicknesses using aCoherent HighLight FL8000-ARM fiber 토토 롤링 디시.A special weld termination recipe was 토토 롤링 디시ilized that independently ramped down the power in the center and ring beams.

This testing successfully demonstrated spatter-free, crack-free welds at process speeds of up to 8.8 m/min for the thinnest material combination (2 mm total thickness) and 6.3 m/min for the thickest (5.7 mm total thickness). These speeds are substantially higher than those achievable with traditional fiber 토토 롤링 디시s. In all cases, weld penetration was highly uniform thanks to closed-loop power control and the inherent back-reflection insensitivity of the Coherent FL-ARM 토토 롤링 디시.

These test results show that the토토 롤링 디시 HighLight FL-ARMcan deliver high-quality, low defect welds in high-strength steel. The high throughp토토 롤링 디시 rates achieved, and the inherent reliability of thisfiber 토토 롤링 디시technology makes it a cost-effective sol토토 롤링 디시ion for a토토 롤링 디시omotive seat production applications. This p토토 롤링 디시s a토토 롤링 디시omakers in the driver’s seat when implementing the most advanced designs, and allows consumers to rest easy with a feeling of comfort and safety.
