Compared with traditional welding equipment, laser welding equipment has stronger functions, higher reliability, is more convenient to operate without vacuum conditions, and can weld a wider range of materials. So can laser welding machines weld aluminum?
1. Can a laser welding machine weld aluminum?
Yes. Aluminum, copper, etc., because of their high metal reflectivity and alloy composition, are prone to explosion if the zinc content is large for ordinary laser welding. Therefore, you may have questions about whether the laser welding machine can weld aluminum. The laser welding equipment does not need to be in a vacuum. The welding is completed under the condition, that aluminum, copper, metal alloys, etc. can be welded. Moreover, the weldable materials and welding effect of laser welding equipment are better than traditional spot welding. The welding speed is faster and can effectively reduce the cost compared with spot welding. The welding area is raised, the range of use is wider, and it is safer to weld special materials, so it can weld aluminum.
2. Range of welding materials for laser welding machines
1. Plastic material products: Almost all thermoplastic plastics and thermoplastic elastomers can use laser welding technology. Commonly used welding materials include PP, PS, PC, ABS, polyamide, PMMA, polyformaldehyde, PET, and PBT.
2. Powder metallurgy material products: Laser welding technology has entered the field of powder metallurgy material processing with its unique advantages, opening up new prospects for the application of powder metallurgy materials, such as using the brazing method commonly used in the connection of powder metallurgy materials to weld diamond. Because the bonding strength is low and the heat-affected zone is wide, it cannot adapt to high temperatures and high strength requirements, causing the solder to melt and fall off. Laser welding can improve welding strength and high-temperature resistance.
3. Stainless steel material products: Under normal circumstances, stainless steel welding is easier to obtain high-quality joints than conventional welding. Because of the high welding speed and small heat-affected zone of laser welding, the overheating phenomenon and the adverse effects of large linear expansion coefficients during stainless steel welding are reduced, and the welds have no shortcomings such as pores and inclusions. Compared with carbon steel, stainless steel is easier to obtain deep penetration and narrow welds due to its low thermal conductivity, high energy absorption rate, and melting power.
4. Integrated circuits and semiconductor equipment casings: Laser welding is widely used in the electronics industry, especially in the microelectronics industry. Because laser welding has a small heat-affected zone, rapid heating concentration, and low thermal stress, it shows unique advantages in the packaging of integrated circuits and semiconductor device casings.
