Product introduction
Most of the continuous laser welding is a high-power laser, the power is more than 500 watts, generally more than 1mm plate should use this laser. The welding mechanism is based on the hole effect of deep penetration welding, depth to width ratio is large, can reach more than 5:1, welding speed is fast, and thermal deformation is small. It is widely used in machinery, automobile, ship and other industries.
Structural Analysis
Technical parameters
Detail advantage
Laser welding is mainly for the welding of thin-wall materials and precision parts, which can realize spot welding, butt welding, overlap welding, sealing welding and so on
It has high depth to width ratio, small weld width, small heat affected zone, small deformation and fast welding speed
The weld is smooth, beautiful, no processing after welding or only a simple processing process
The weld has high quality, no porosity, can reduce and optimize the impurities of the base material, the tissue can be refined after welding, and the strength and toughness of the weld are at least equal to or even exceed the base metal
It can be accurately controlled, the focus point is small, and the positioning can be highly accurate. The non-contact remote welding can be performed on the parts that are difficult to access. It has greater flexibility and is easy to realize automation
The laser output mode is very flexible, which can conveniently achieve energy splitting or time splitting or both energy splitting, and can carry out multi-beam processing and multi-station processing at the same time, effectively improving production efficiency
The separation of the host and the workbench allows the different needs of the customer to be economically realized
The laser energy is distributed according to the cap shape in the spot range, and the solder joint is smooth and beautiful, which is especially suitable for spot welding and can realize the welding between some dissimilar materials
Working principle and characteristics
Scope of application
Ø The working principle of fiber laser: The use of doped rare earth glass fiber as the gain medium of the laser, under the action of the pump light, it is easy to form a high power density in the fiber, resulting in the laser level of the laser working material "particle number inversion", when appropriate to add a positive feedback loop (form a resonator) can form a laser oscillation output. The laser generated by the fiber laser is output through the fiber and cooperated with the supporting equipment to complete the corresponding welding application. Fiber lasers are divided into pulsed fiber lasers and continuous fiber lasers. The single point energy of pulsed fiber laser is adjusted by setting the peak power, frequency and pulse width of laser. Continuous fiber lasers adjust the output laser power by setting the average power.
