Handheld laser welding aluminum alloy process
Difficulties of laser welding machine welding aluminum alloy Aluminum alloy has the following characteristics: light weight, non-magnetic, good low temperature performance, good corrosion resistance, good formability, etc., so it is widely used in various welded structure products. Using aluminum alloy instead of steel plate material welding, the structure weight can be reduced by more than half.
The effect of laser welding on the human body
Is laser welding harmful to the human body? I believe that many of my friends are more concerned about this issue. Today, I will introduce the impact of laser welding on the human body. Laser deep penetration welding can thoroughly penetrate the workpiece, and has large input energy and fast welding speed. It is currently the most widely used laser welding mode. This method is undoubtedly a more convenient way of welding. Laser welding machines can generally be divided into heat conduction welding and deep penetration welding. The heat of the former diffuses into the workpiece through heat transfer, and only melts on the surface of the weld. The interior of the workpiece is not completely penetrated, and vaporization is basically not generated. It is mostly used at low speeds. Welding of thin-walled materials; the latter not only completely penetrates the material, but also vaporizes the material to form a large amount of plasma. Due to the large heat, a…
How to choose fiber laser marking machine?
Fiber laser marking machine is a commonly used model in the marking industry now. The use of fiber laser laser marking materials is clear and exquisite without loss, so it has been favored by most users. At present, the price of fiber laser printers on the market is as low as 40,000 to 50,000, and the expensive one is more than 200,000. If you accidentally buy a low-quality fiber laser marking machine, it will not only waste a lot of money, but also seriously affect your work. schedule. So how to choose a fiber laser marking machine? I believe this is a question that customers who are interested in buying a fiber laser marking machine are very concerned. The editor tells everyone how to distinguish the quality of a fiber laser marking machine.
