Applications such as e-mobility manufacturing are driving an increased need to 에볼루션 바카라 traditionally “difficult” materials, like copper and aluminum, or to join dissimilar materials. Introduced in 2019, the Coherent Smart에볼루션 바카라+ precision remote 에볼루션 바카라ing head provides the precise energy distribution and penetration depth control necessary to successfully produce these types of 에볼루션 바카라s.
The new PH20 Smart에볼루션 바카라+ extends the range of this proven technology to lasers of up to 5 kW power. This makes it compatible with a larger selection of single-mode standard and Adjustable Ring Mode (ARM) fiber lasers including the Coherent HighLight FL CSM ARM, HighLight FL CSM, and PowerLine FL 1000/1500. The result is the ability to 에볼루션 바카라 both thin and thick materials with unmatched precision at high speeds.
What’s so smart about Smart에볼루션 바카라+?
Smart에볼루션 바카라+ achieves this combination of speed and precision by mating fixed beam delivery optics with a highly dynamic galvanometer scanning module (speeds up to 4 kHz). This is controlled by sophisticated software for producing a variety of pre-programmed scan patterns. These “smart” patterns move well beyond traditional beam wobble to encompass spirals, ellipses, and other complex shapes.
In addition to higher power operation, software upgrades in the PH20 Smart에볼루션 바카라+ enable the system to dynamically adapt beam motion (pattern orientation, size, and oscillation frequency) to compensate for individual workpiece variations as measured by the vision system. When matched with an ARM laser, this beam control can be synchronized with high speed, independent modulation of the power in the center and ring beams. This provides an unprecedented level of spatial and temporal control of how laser power is applied.
All this delivers more consistent 에볼루션 바카라 quality and seam dimensions, while simultaneously relaxing part fit-up requirements. And, with an expanded 50 x 50 mm scan field, the newest Smart에볼루션 바카라+ can sometimes eliminate gantry movement for even greater throughput speed.
A better 에볼루션 바카라
Results demonstrate the ability of Smart에볼루션 바카라+ to precisely control 에볼루션 바카라 seam dimensions and shape, as well as reduce heat input. For example, the two photos compare 에볼루션 바카라s from a traditional multi-mode laser (800 µm approximate focused spot size) with a much lower power, single-mode laser (30 µm approximate focused spot size) controlled using Smart에볼루션 바카라+.
A traditional multi-mode pulsed laser produces a weld (left) with uneven depth and a relatively large heat-affected zone, while Smart에볼루션 바카라+ paired with a single-mode fiber laser produces a weld (right) with uniform depth and strength, and minimal heat-affected zone.
Smart에볼루션 바카라+ produces a 에볼루션 바카라 cross-section which is more rectangular and 40% larger than the traditional approach. At the same time, it creates a much smaller heat-affected zone because of the reduced overall energy input. As a result, thermal stress and crack formation are minimized and 에볼루션 바카라 strength is increased.
Additionally, the smaller focused spot achieved with a single-mode source increases the energy concentration. This improves process stability on highly reflective materials – like copper or aluminum – which usually are difficult to 에볼루션 바카라, particularly with infrared lasers.
