All kinds of metallaser welding machineThe role of the shielding gas is to surround the weld pool to prevent its oxidation, and appropriately accelerate the cooling of the weld, and reduce the width of the weld heat affected zone. The difference in the physical properties, thermal conductivity and solubility in water of the shielding gas has different effects on the welding quality. At high temperatures, denser gases may still be better around the welded parts to prevent oxidation of the welded parts.

All kinds of metallaser welding machineThe effect of gas density on welding is greater than that of its ionization. In order to reduce or eliminate the influence of process parameters such as laser power, defocusing, welding speed, pulse frequency, type and flow rate of shielding gas on steel and aluminum laser welding defects, laser marking has the advantages of anti-wear and non-fading. The laser beam is irradiated to the surface of the object to be processed to remove or melt the material and change the surface of the object, so as to achieve the processing purpose. It is a non-contact processing, there is no mechanical force, the processed material will not be deformed, and the damage is small.

This has become a clear advantage that distinguishes laser technology from other processing methods. For example, in the field of crystal marking, according to the traditional paint marking method, due to the poor adhesion between stainless steel and paint, the processed crystal cannot be cleaned, which brings a lot of inconvenience. Nowadays, laser marking is the most commonly used method in this field. The traces of formation are clear, persistent and indelible.
