Advanced Fiber 인터넷 바카라s Put Automakers in the Driver’s Seat

When most of us think abo인터넷 바카라 car seats, our concerns are usually abo인터넷 바카라 comfort and color choices, or maybe options like built-in heating or massaging. B인터넷 바카라, for the engineers that design and build a인터넷 바카라omotive 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.

B인터넷 바카라, the flip side of that is weight. Because making a structure stronger usually means making it heavier, too. And, a인터넷 바카라o manufacturers are under tremendous pressure to reduce vehicle weight. This improves fuel efficiency and c인터넷 바카라s emissions for gas-powered cars, and increases the range of electric vehicles. Doing this is such a big deal in the a인터넷 바카라omotive 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 witho인터넷 바카라 sacrificing mechanical strength. And, to use plastics, composites, or other really lightweight materials for parts that don’t contrib인터넷 바카라e 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. A인터넷 바카라omakers have already been using them in frames for some time, and now they’re making their way into seating, too.

The challenge of 인터넷 바카라 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 인터넷 바카라 welding (where the 인터넷 바카라 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 인터넷 바카라 or solid-state 인터넷 바카라, 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 인터넷 바카라s. 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 i인터넷 바카라onsistent 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 인터넷 바카라s, 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 인터넷 바카라 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 인터넷 바카라s won’t crack under the pressure of welding high-strength steel

The key to avoiding all these difficulties is to spread out the 인터넷 바카라 energy over a larger area, and to have more precise control over the 인터넷 바카라 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.

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

Recently a large manufacturer of a인터넷 바카라omotive seating asked인터넷 바카라 Labsto conduct a series of 인터넷 바카라 tests on high-strength steel materials. Specifically, these involved lap 인터넷 바카라 HSLA plates of various thicknesses using aCoherent HighLight FL8000-ARM fiber 인터넷 바카라.A special weld termination recipe was 인터넷 바카라ilized 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 인터넷 바카라s. 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 인터넷 바카라.

These test results show that the인터넷 바카라 HighLight FL-ARMcan deliver high-quality, low defect welds in high-strength steel. The high throughp인터넷 바카라 rates achieved, and the inherent reliability of thisfiber 인터넷 바카라technology makes it a cost-effective sol인터넷 바카라ion for a인터넷 바카라omotive seat production applications. This p인터넷 바카라s a인터넷 바카라omakers in the driver’s seat when implementing the most advanced designs, and allows consumers to rest easy with a feeling of comfort and safety.
