The rapid development of aluminum alloy laser welding technique in the recent years has made aluminum alloy more applicable. It is a novel welding technique and is getting more and more popular among users.
What is aluminum alloy? How laser technique can benefit the aluminum alloy processing?
Aluminum and aluminum alloy both have excellent qualities, such as fantastic hardness and strong ability to resist corrosion. Therefore, they are have very wide applications in many industries, such as military industry and mechanics industry. Since aluminum alloy belongs to nonferrous metal, it requires welding. As science develops, the aluminum alloy welding technique also develops. And the advent of laser welding technique does help improve aluminum alloy welding to a new level.
Laser welding technique which is a novel welding technique uses laser light as the welding heat source. This can help prevent the waste of the consumable items and improves the welding efficiency. At the same time, laser welding technique uses robot or CNC machine as the mobile system so that human labor can be reduced to a large extent. What’s more, the laser light features renewability, cleanness and powerful energy focus ability, so it can greatly improve the welding quality.
1.The laser power of laser welding machine
Laser welding machine requires high power laser. When laser welding machine is equipped with a high power laser, the welding performance could be stable and continuous. Otherwise, the welding can only be achieved on the surface of the aluminum alloy and can not reach the inside.
2.Laser welding speed
As the laser power of the laser welding machine increases, the welding speed also increases. The increasing welding speed leads to small weld penetration. On the contrary, if the welding speed slows down, the aluminum alloy will be over welt or is totally penetrated. Therefore, choosing laser welding technique can reduce welding failure and welding cost to a great extent.
As mentioned above, aluminum alloy laser welding machine is powered by high power laser. So what would be the ideal laser source for metal welding? Well, fiber laser is no doubt the perfect candidate. High power fiber lasers are often paired with an efficient cooling system to prevent themselves from overheating. S&A CWFL series circulating water cooler is suitable for cooling high power fiber laser up to 20KW. Find out more about this series cooler at https://www.chillermanual.net/fiber-laser-chillers_c2
