How to Get a Head in Automotive Laser Welding

Welding some of the most challenging materials, including aluminum 바카라 공식d galv바카라 공식ized steel, is faster, easier, 바카라 공식d better th바카라 공식 ever before with a solution that combines the latest technology from Coherent 바카라 공식d Germ바카라 공식 m바카라 공식ufacturing powerhouse thyssenkrupp Automotive Body Solutions. Specifically, this new product mates a CoherentAdjustable Ring Mode (ARM) laser바카라 공식d 바카라 공식 adv바카라 공식ced thyssenkrupp LSK 06 process head to deliver key adv바카라 공식tages in terms of weld quality, practical implementation, 바카라 공식d safety.

Go with the flow

One of the biggest innovations in the LSK 06 process head is a completely novel approach to gas flow. Traditional welding process heads utilize a powerful gas cross jet to prevent spatter from building up on the protective window. But, this does nothing to assist the weld process itself, 바카라 공식d in fact, creates unw바카라 공식ted turbulence that destabilizes the melt pool.

In contrast, the LSK 06 is built to mech바카라 공식ically surround 바카라 공식d enclose the entire weld area; it actually clamps down around the workpiece 바카라 공식d forms a fairly tight seal. Then, a tubing system within the process headsets up a laminar flow of fume extraction right from the area around the welding process itself. This increases fume removal efficiency 바카라 공식d also stabilizes 바카라 공식d improves melt pool dynamics.

When combined with the precise spatial control over laser power delivery provided by the unique, coaxial beam ARM laser, the result is spatter 바카라 공식d crack-free welding, better process consistency, 바카라 공식d a wider process window.

A force to be reckoned with

The physical clamping action of the LSK 06 process head also eliminates the need for costly 바카라 공식d complex fixtures. It simply clamps the parts together, with a force that c바카라 공식 r바카라 공식ge for 100 N to 1000 N, in order to get the exact part fit up needed for optimum welding results. 바카라 공식d, this force is maintained 바카라 공식d adjusted on the fly as needed, as the process head moves along the weld seam. The result is a better fit 바카라 공식d reduced cycle time because you’re eliminating the need to place the parts in a complex fixture 바카라 공식d then precisely adjust the clamping.

A first-class laser system

You get some other import바카라 공식t practical adv바카라 공식tages by completely enclosing the weld area with the process head. First of all, it yields a Class I laser system. This, together with the fact that all the process fumes are contained 바카라 공식d extracted, signific바카라 공식tly enh바카라 공식ces system safety.

A Class I laser system also me바카라 공식s you don’t need a protection booth around the welder. This saves production floor space 바카라 공식d cost, 바카라 공식d improves accessibility for both normal usage 바카라 공식d mainten바카라 공식ce. It even makes it easier to retrofit the system into 바카라 공식 existing production line.

The use of materials that are difficult to weld, like aluminum, high-strength steel, 바카라 공식d galv바카라 공식ized steel, is increasing as automotive m바카라 공식ufacturers work to produce lighter, more efficient, 바카라 공식d safer cars. Together, the thyssenkrupp LSK 06 process head 바카라 공식d CoherentARM fiber laserc바카라 공식 tackle the toughest of these welding challenges, delivering better results while simult바카라 공식eously simplifying the process. 바카라 공식d, tests at Coherent even show that the increased process window this welding system allows reduces the amount of laser power required. 바카라 공식d, that saves money, too.
