Introduction to the application of laser welding of copper materials
Date：2024-01-14 Source: This website
Laser welding is very hot in recent years, from small daily hardware to auto parts, new energy batteries to sheet metal products, laser welding has formed a prairie fire trend, welding market is the next flashpoint of laser, has been the consensus of the laser industry. The welding of aluminum uses composite ring spots and other solutions, and its effect has been recognized by the field of new energy batteries, but the welding difficulties of copper have not been well solved. Recently, many manufacturers have given new solutions for copper welding, and Germany TRUMPF has made a fortune in this industry by taking advantage of its green laser. We Jinghai introduced our own blue light composite welding solution to solve the problem of copper welding.
Why the short-wavelength organ can be very good welding, because copper at room temperature only 5% absorption of infrared laser, in the melting state is only 20%, so in the past we used high-density infrared laser can also solve some problems, but welding instability and welding defects can not be avoided, However, short-wavelength green light and blue light can achieve more than 50% absorption rate, so under the same spot size, blue light 500W can achieve the effect of 6000W infrared fiber laser. Because the absorption rate of blue light to copper is very stable, its entire molten pool is also very stable, and it can be completely splash-free.
500W blue laser
Suzhou Jinghai Laser has been open to foreign proofing, especially with pain relief items can be proofing tests. We have produced 500W blue laser welding equipment, and the welding of copper materials can replace high-power ultrasonic hot pressure welding in some application scenarios.
High power copper laser welding equipment
