Laser cleaning machines have shown remarkable results in cleaning stainless steel weld spots. According to research, laser cleaning technology can quickly remove the oxidation color of stainless steel welds and heat-affected zones, as well as paint and rust on the surface of stainless steel, and can form a new passivation layer to improve the corrosion resistance of stainless steel. In practical applications, laser cleaning machines can efficiently remove attachments or surface coatings on the surface of stainless steel, such as surface oxide layer cleaning before welding and weld stain cleaning after welding, which can be done quickly, without damaging the base material, No pollution emissions.
The mechanism of laser cleaning is mainly based on the photophysical reaction caused by the interaction between high-intensity beam, short-pulse laser and the pollution layer. When a laser beam irradiates the surface of stainless steel, the dirt, rust spots or coating on the surface will absorb the laser energy. On the one hand, the contaminants may vaporize and volatilize; on the other hand, the contaminants may instantaneously expand due to heat and overcome the adsorption of particles on the surface. force to make it break away from the surface of the object, thereby achieving the purpose of cleaning.
In addition, when cleaning stainless steel welds, the laser cleaning machine can remove all the oxide layers in the welds and heat-affected zones, and the treated surface can form a new passivation layer, which has good corrosion resistance. There is no major color difference between the stainless steel surface after laser cleaning and the original surface, which is very important for maintaining the appearance quality of stainless steel products.
In summary, the laser cleaning machine is not only effective in cleaning stainless steel welding spots, but also has the advantages of environmental protection, high efficiency, and non-destructiveness, making it an ideal cleaning method.
