Copper is a highly reflective material, and the thermal conductivity of copper products is very large, so the laser welding machine will have certain difficulties when welding copper and copper alloys. However, with the gradual development of laser technology, the emergence of high-power and high-brightness fiber lasers overcomes these limitations one by one. Through new and suitable fiber laser welding machines, stable and defect-free joints can be created in an efficient welding process. . Let's introduce Leapion laser:
Compared with other solid-state lasers, this type of laser has excellent beam quality and focusing performance. IPG can provide high-power single-mode lasers up to 10 kW, and high-brightness multi-mode lasers with power over 10 kW, all of which have rugged and industry-proven designs.
Using these single-mode fiber lasers and low-order mode high-brightness lasers, a power density higher than 108W/cm² can be achieved, and reliable coupling can be achieved even at a power of several hundred watts. Compared with ordinary multimode lasers of comparable power, these lasers are up to fifty times stronger.
Generally, welding speeds less than 5m/min will face welding instability problems, such as spatter, porosity and irregular weld surface.
As the welding speed increases, this instability gradually disappears. In the welding speed range of 5-15m/min, the quality reaches an acceptable level. If the welding speed is higher than 15m/min, the weld produced is basically free of defects (Figure 3). This means that the best welding parameters are within the limits that traditional motion systems (such as robots) can achieve.
As the swing diameter increases and the speed of the circular beam increases, the surface quality becomes more and more stable. Depending on the swing parameters and spot size, the light beam and the formed keyhole usually move in a molten metal pool or in solid and resolidified materials. In both cases, the brazing process can achieve stability.
In addition, the swing diameter can be used to customize the shape of the weld cross-section, as follows:
A small swing diameter will form a typical V-shaped cross section for laser welding;
The larger diameter can change the welding seam from a V shape to a U shape or a very regular rectangle;
If the energy input per unit length of the weld is constant (E = P vw), the cross section of the weld remains almost unchanged.
1) High power density can realize instantaneous coupling and formation of keyholes, and can realize stability and high absorptivity even at a wavelength of 1070nm.
2) Through the highly dynamic beam swing, the welding process is very stable, thereby reducing or avoiding the phenomenon of pores and spatter, and finally produce high-quality welds.
