Information

When Automatic laser welding machine performs welding work, the main function is the value of laser power density. Different materials have a critical power density threshold. To perform welding, the power must exceed this critical threshold, so that the material can melt and the welding effect can be achieved. When the laser power is constant, the welding speed becomes the main factor that affects the welding strength, and the suitable laser welding speed is the guarantee for the firm welding.

Automatic laser welding machine

In the welding industry, some people think that the faster the welding speed of the Automatic laser welding machine, the better. In fact, the laser welding speed cannot be too fast or too slow. It must be suitable. Too fast and too slow will affect the strength of laser welding. The laser power and welding speed affect the penetration depth and penetration width, which in turn affects the welding strength. When the laser power is constant, the welding speed becomes the main factor that affects the welding strength.

Excessive power of Automatic laser welding machine burns the alloying elements in the weld zone, which reduces the strength and mechanical properties of the weld. It is also because the high welding power deteriorates the weld formation and increases surface holes. Too high welding speed will reduce the strength of the weld. This is because the number of pores in the weld increases and the effective bearing area decreases. The welding speed and the laser power affect the welding depth together. When the speed is constant, the weld strength has a critical zone. When the power is lower than its lower limit, the intensity increases as the power increases. This is because as the power increases, the penetration increases and the bonding strength increases; when the power is greater than the upper limit of the critical zone, the intensity increases with the increase in power. reduce.
