The beam mode of the laser of the fiber laser welding machine is divided into two types: single-mode and multi-mode. In laser welding applications, the focused spot has a great influence on the weld penetration and indirectly affects the tensile strength of the weld. The beam pattern has a certain effect on the weld penetration. Let's share with Leapion Laser below what effect different lasers have on the weld penetration.
1. The core of single-mode laser is relatively thin, and the beam quality is better than that of multi-mode. The laser energy has a Gaussian distribution, the middle energy density is the highest, and the three-dimensional image is a sharp round mountain peak.
2. The core of the multi-mode laser is thicker than that of the single-mode laser, the beam quality is worse than that of the single-mode laser, and the energy distribution is more average than that of the single-mode laser spot.
1. Under the condition of a certain laser power, as the welding speed decreases, whether single-mode or multi-mode lasers are used, the weld penetration will gradually increase.
2. Under the condition of certain laser power, as the defocusing amount decreases, whether single-mode or multi-mode lasers are used, the weld penetration will gradually increase.
3. When the power, defocus and speed remain unchanged, the welding penetration of single-mode lasers is larger than that of multi-mode lasers.
It can be seen that the laser of the fiber laser welding machine is a key factor to ensure good welding quality.
In addition to fiber lasers, there are many other factors that affect the quality of laser welding, such as: shielding gas type, gas flow rate, motion control mode and accuracy, etc.
Among them, there are many factors that affect the welding quality of the laser, such as laser power, welding speed, defocus, etc., but in many cases we tend to ignore the factor of beam mode.
As the types of welding materials become more and more abundant, customers have higher and higher requirements for welding quality. Laser welding technology is an efficient and precise welding method that uses a high-energy density laser beam as a heat source. Now the fiber laser welding machine has been widely used in various industries.
