Introduction
The welding of stainless steel metal wires combined with laser welding technology is becoming more and more mature. As a kind of advanced welding technology, laser welding of stainless steel metal wires can make the welding points of stainless steel metal wires meet the requirements of engineering design, and is increasingly recognized in the engineering field. In the following, we will discuss the welding process parameters of stainless steel metal wires laser welding.
Body
I. Welding Principle
The laser of stainless steel metal wire welding is a kind of welding method which uses laser to irradiate the welding parts, so that the surface temperature of the welding parts will reach the melting point, thus making the two parts be tightly combined and form a stable joint. Compared with other welding processes, laser welding of stainless steel metal wires is more precise. The material only needs to be melted on the surface, which has a small heat-affected zone and will not cause damage to the surrounding material.
II. Welding Process Parameters
The welding parameters of stainless steel metal wires laser welding mainly include laser power, welding speed, spacing between welding points and preheating temperature.
1.Laser power
Laser power is the most important welding process parameter of stainless steel metal wire laser welding. Generally, the higher the output power of the laser, the higher the temperature at the welding point, which is beneficial to the formation of the welding point; but if the output power of the laser is too high, the burning of the stainless steel metal wire will be caused, and the welding will fail. Therefore, when selecting the laser power, it should be determined according to the application of different materials and stainless steel metal wire thickness.
2.Welding Speed
The welding speed of stainless steel metal wire laser welding is also an important welding process parameter. The material melting process of laser welding requires certain time, and the welding speed is related to the output power of laser and the thickness of stainless steel metal wires. The welding speed is too low, that the material cannot obtain enough time to melt, so the welding will fail. Therefore, it is very important to choose an appropriate welding speed for stainless steel metal wire laser welding.
3.Spacing between welding points
The spacing between welding points also has an effect on the welding result of stainless steel metal wires. In general, the spacing between welding points should not be too large. The ideal spacing between welding points is 0.5mm, which ensures that the welding points are evenly arranged and the welding is stable.
4.Preheating Temperature
The preheating temperature should be preheated when laser welding of stainless steel metal wires is performed. The annealing temperature of stainless steel metal wires is too high, and the stainless steel metal wires may become brittle after welding; while the stainless steel metal wires annealing temperature is too low, the melting effect of laser will be reduced and the welding will be failed. Therefore, the preheating temperature should be determined according to the actual situation.
Conclusion
In summary, reasonable selection of welding process parameters of stainless steel metal wires laser welding is very important for the final welding results. It should be noted that in practical applications, the welding process parameters should be adjusted according to the specific conditions of different materials, and the welding effect can be improved through accurate welding parameters.
