Laser welding machine is a kind of automatic welding machine, which is favored and favored by electric welding manufacturing industry. Many manufacturers will introduce laser welding machines to perform electric welding work. So much work has been improved. The role of the shielding gas of the metal laser welding machine is to surround the weld pool to prevent its oxidation, and appropriately accelerate the cooling of the weld, and reduce the width of the heat-affected zone of the weld. Differences in the physical properties, thermal conductivity, and solubility in water of the shielding gas have different effects on the welding quality. At high temperatures, the dense gas around the weldment is still better to prevent the weldment from oxidizing.

The gas density of metal laser welding machines has a greater influence on welding than its ionization effect. In order to reduce or eliminate the influence of process parameters such as laser power, defocusing, welding speed, pulse frequency, shielding gas type and flow rate on steel and aluminum laser welding defects, laser marking has the advantages of anti-wear and non-wear. Laser processing irradiates a laser beam to the surface of the object to be processed to remove or melt material and change the surface of the object, thereby achieving the purpose of processing. 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 a common method in this field, and the marks formed are clear, durable and indelible.
