Laser welding machine is a kind of automatic welding machine, which is favored by the electric welding manufacturing industry. Many manufacturers will introduce laser welding machines for electric welding. As a result, much work has been improved.

The shielding gas of metal laser welding machine is used to surround the welding pool to prevent its oxidation, appropriately accelerate the cooling of the weld, and reduce the width of the heat affected zone of the weld. Differences in physical properties, thermal conductivity and solubility of shielding gas in water have different effects on welding quality. At high temperatures, the dense gas around the weldment will still be better to prevent oxidation of the weldment.

The gas density of metal laser welding machine has more 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 laser welding defects of steel and aluminum, laser marking has the advantages of wear resistance and non wear.

Laser processing irradiates the laser beam on the surface of the object to be processed to remove or melt materials and change the surface of the object, so as to achieve the processing purpose. It is a non-contact processing, without mechanical force, and the processed materials will not be deformed, with little damage.

This has become an obvious advantage, distinguishing laser technology from other processing methods. For example, in the field of crystal marking, according to the traditional paint marking method, the processed crystals cannot be cleaned due to the poor adhesion between stainless steel and paint, 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.
