With the continuous development of lasers, laser welding machines are becoming more and more active in the field of metal sheet welding, such as laser welding machines using spot welding processes in the welding of aluminized steel. What problems do you need to pay attention to when welding aluminum plated steel plates? In order to achieve the purpose of welding aluminized steel plate and need to go through what treatment? The processed sheet metal profile goes through that process before it can be applied in the next step.
When laser welding machines use the spot welding process to process aluminized steel plates, higher currents and closer welding process monitoring are required than cold-rolled steel plates, and electrode maintenance is very important to be corrected at any time to prevent deformation of the contact surface. Therefore, in the manufacture of aluminized steel will be doped with non-metallic elements, the aluminized steel plate is an aluminum-silicon alloy plated steel plate, of which the aluminum content is 90%, silicon 10%, the plating of the aluminized steel plate is higher than the melting point of the galvanized steel plate, it is not easy to flow, and the melting area is small, so it is not necessary to use the welding galvanized steel plate so large current. At the same time, the harmful smoke generated in the welding process is very little, which is environmentally friendly.
The spot welding process of laser welding machine has completed the welding work of aluminized steel, but there is a layer of gray black material at the weld after welding. This gray layer is what's left of the silicon reaction. In order to deal with this residue can be cleaned with strong acidic substances, but it goes against the consciousness of energy saving and environmental protection, so the use of new, green cleaning methods is the way.
It is said that the laser is all-round, it can not only weld metal but also do cleaning equipment. The use of laser cleaning equipment to clean the weld can not only clean the residue will not harm the base, but also a green cleaning means.
The cleaning process of laser cleaning equipment depends on the characteristics of the light pulse generated by the laser, based on the photophysical reaction caused by the interaction between the high-intensity beam, the short pulse laser and the contaminated layer.
Laser cleaning is a "green" cleaning method that does not require the use of any chemicals and cleaning fluids. The cleaned waste is basically solid powder, small in size, easy to store, recyclable, can easily solve the environmental pollution problems caused by chemical cleaning; The non-abrasive and non-contact nature of laser cleaning makes these problems easily solved; The laser can be transmitted through optical fiber, and is compatible with the robot hand and robot, which can easily achieve long-distance operation, and can clean the parts that are difficult to reach by traditional methods to ensure the safety of personnel; Laser cleaning can remove all kinds of pollutants on the surface of various materials, achieve the cleanliness that can not be achieved by conventional cleaning, and can also selectively clean the pollutants on the surface of the material without damaging the surface of the material.
