What to pay attention to when using laser welding for aluminum alloy materials

2019-03-30

There are many materials for laser welding, including aluminum alloys, copper, titanium alloys, nickel, and other materials. The welding process types are also quite complex, with a wide range of applications. Therefore, laser welding is often used in industrial production, such as: metal sheet welding, precision welding, and welding types involving sealing welding, splicing, butt welding, corner welding, continuous welding, and spot welding operations. Moreover, there is no need for secondary processing after welding, the weld seam is fine, the heat-affected zone is small, no external force is required, and there is no deformation. Thus, the welding quality is good, the welding speed is fast, and the efficiency is high. More importantly, automation is easier to achieve, especially with the emergence of high-power lasers, which makes welding thicker materials smoother, no longer affected by material thickness factors. The application range will inevitably become broader.
Aluminum alloy is a commonly used material in industrial production, especially in doors and windows, hardware, household appliances, and kitchen utensils. Aluminum alloy materials are always closely related to our daily lives. With the improvement of people's living standards, users' requirements for product precision craftsmanship have also increased. Therefore, as a daily necessity, aluminum alloy materials require the use of more advantageous laser welding machines during the production welding process, specifically designed for aluminum alloy welding.
Using traditional welding processes for aluminum alloys is relatively difficult to trust. Aluminum alloys have strong thermal conductivity but poor heat resistance, making them unable to withstand high temperatures, which can easily lead to expansion. The material is also relatively soft, making it easy to process and shape. However, when using laser welding, it is essential to control the welding process technology well. Otherwise, due to the high reflectivity of aluminum alloy materials, laser energy is difficult to be absorbed by aluminum alloys. Therefore, only with sufficient power and energy password can it be well absorbed by aluminum alloys. Coupled with the technical advantages of lasers themselves, laser welding can effectively address the physical and chemical shortcomings of aluminum alloy materials, solving some technical problems that arise during the welding process. Thus, the advantages of aluminum alloy laser welding machines can be highlighted in several aspects.
1. High energy password, good beam quality, fast welding speed, non-contact processing, neat surface welding, no need for secondary processing.
2. No maintenance and consumables required, cost-saving, belongs to new energy industrial application equipment, supported by national policies, and further improves product quality and market competitiveness for enterprises.
3. The equipment occupies a small space, combined with relevant welding software and automated control mechanisms, welding is simple, and the speed of sampling or production is fast, making it a flexible and user-friendly industrial welding device.
4. Reasonable purchase funding, higher cost-effectiveness for long-term use, can bring better development opportunities for enterprises.
Well, the advantages of aluminum alloy laser welding machines in industrial production applications are already evident. If you are still not very clear and want to introduce relevant equipment to accelerate the development of your enterprise and improve the quality level of product craftsmanship, then pick up your Mobile and quickly contact our SHINHOP laser engineers.
