Why is the laser welding machine bright and dark at the same time?

When you use the laser welding machine, you will find that the laser welding machine is bright and black at the same time. Why is this? The following laser welding machine manufacturers will give you answers.

1. Reasons
   ① If the power of the laser welding machine is too high or too low, the temperature of the welding area will be uneven, resulting in blackening on both sides of the weld bead;
   ② The atmosphere in the welding area is poor. Poor atmosphere in the welding area will lead to the formation of oxides, which will lead to blackening on both sides of the weld bead;
   ③ If the power of the laser welding machine is too high or too low, the temperature of the welding area will be uneven, resulting in blackening on both sides of the weld bead;
   ④ Poor atmosphere in the welding area. Poor atmosphere in the welding area will cause the formation of oxides, resulting in blackening on both sides of the weld bead.
2. Solution
   ①Adjust the welding speed according to the welding material and welding thickness to ensure uniform temperature in the welding area;
   ② Ensure that the surface of the welding area is clean. To ensure that the surface of the welding area is clean, cleaning, mechanical cleaning and other methods can be used to avoid a bad atmosphere in the welding area;
   ③Adjust the power of the laser welding machine according to the welding material and welding thickness to ensure uniform temperature in the welding area;
   ④ Ensure that the atmosphere in the welding area is good. Inert gas can be used to protect the welding area to avoid the formation of oxides.
3. Prevention methods
   ① Make preparations before welding. Before welding, you should make preparations before welding, including cleaning the welding area, adjusting the parameters of the laser welding machine, etc.;
   ② Strictly follow the operating procedures. During the operation of the laser welding machine, you should strictly follow the operating procedures to avoid operating errors;
   ③ Check the equipment regularly to ensure the normal operation of the equipment and avoid equipment failure leading to a decrease in welding quality.
