Particularly in our three core industries – automotive, medical technology, and consumer electronics – we know this field like the back of our hand. We take advantage of our knowledge of the standards, regulations, requirements, and challenges in the various industries by putting our extensive expertise in laser plastic welding to targeted use. Laser plastic welding is what we know best – for all productions areas, shapes, colors and functions.
In order to achieve laser welding of aluminum alloys and solve the above-mentioned problems, it is mainly solved from the following aspects. Because the cooling rate of laser welding is too fast, the problem of hydrogen gas holes is more serious, and there are more holes caused by the collapse of small holes in laser welding. In short, the problem of joint softening is another problem in laser welding of aluminum alloys.

A corresponding cross section of an overlap flange, cut and edge-welded with a IPG Photonics YLR kW fiber laser is presented in Figure 4.
While the concept of multifunctional laser processing is straightforward and the market seems to be ready for such a device, some technical problems had to be solved before it became reality. In addition, the welding speed can be appropriately increased during welding to avoid small pits. If the welding speed is too fast, the penetration depth of the weldment becomes relatively small.
When the focal point is kept slightly below the surface of the workpiece, the depth of penetration is maximized. Light amplification by stimulated emission of radiation is called laser. Based on the application, we can therefore advise you in finding the best solution for you. Uses the most advanced light shielding system to eliminate the irritation to eyes by light during working.
During the instantaneous solidification process, after the fine-grained strengthened structure is transformed into the as-cast structure, its hardness and strength will decrease. Refinement strengthening, solid solution strengthening, and aging precipitation strengthening are several strengthening mechanisms of aluminum alloys. This is because of the high density of free electrons in aluminum alloys.
Compared to common laser welding, HW-A wobble laser welding best for wider seam welding and deep penetration welding. This process is characterized by high efficiency and high welding speeds. This process is used in applications requiring deeper welds or where several layers of material have to be welded simultaneously. For example, our budget pick, the Neutec® PulsePoint™ Plus 20, delivers up to 20 joules of output energy. Although 20 joules will be enough for most laser-welding applications, especially on silver, if you need to work on platinum and titanium, for example, you’ll want a more powerful tool.
Before that, these systems were only used in research institutes and specialist companies. Jewelry manufacturers currently using laser welders are often amazed at the wide range of applications and ability to produce a higher quality product in less time with fewer materials. Lasers can also be used to re-tip prong settings, repair bezel settings, resize rings, and repair bracelets without removing stones. Sponge-type porosity, normally identified in the final polishing process, can be filled and repaired by using a laser.
