Processing Principle of Laser Welding Technology
Latest company news about Processing Principle of Laser Welding Technology

Laser radiation heats the surface to be processed, and the surface heat diffuses to the inside through heat conduction. By controlling the laser pulse width, energy, peak power and repetition frequency and other laser parameters, the workpiece is melted to form a specific molten pool.

 

Laser welding can be realized by continuous or pulsed laser beam. The principle of laser welding can be divided into heat conduction welding and laser deep penetration welding. The power density is less than 10 W/cm2 for heat conduction welding. At this time, the penetration depth is shallow and the welding speed is slow; when the power density is greater than 10 W/cm2, the metal surface is recessed into "holes" by heating, forming deep penetration welding. It has the characteristics of fast welding speed and large aspect ratio.

Laser welding technology is widely used in high-precision manufacturing fields such as automobiles, ships, airplanes, and high-speed railways. It has brought a significant improvement to people's quality of life and has led the home appliance industry into the era of precision manufacturing.

 

Especially after the 42-meter seamless welding technology created by Volkswagen has greatly improved the integrity and stability of the car body, the leading home appliance company Haier Group grandly launched the first washing machine produced with laser seamless welding technology. Advanced laser technology can help The lives of the people have brought tremendous changes.
