Laser marking machine technology?

Leihan machine, also known as laser marking machine, is a machine used for laser material processing. It can be divided into laser marking machine, automatic laser marking machine, laser marking machine according to its working mode Spot welding machine, fiber transmission laser marking machine.

First, the steel mold.

S136, SKD-11, NAK80, 8407, 718, 738, H13, P20, W302, 2344 and other mold steels have good laser welding effect.

Second, carbon steel.

Carbon steel is welded by laser, the effect of laser welding is very good, and the content of impurities determines the quality of laser welding. In order to ensure the quality of laser welding, preheating is required when the carbon content exceeds 0.25%. When laser welding steels with different carbon content, the welding torch may be slightly offset to the soft side to ensure the quality of the connection. When laser welding carbon, due to the fast heating and cooling of laser welding, when laser welding carbon steel. As the carbon content increases, the sensitivity of weld cracks increases. Medium carbon steel and ordinary alloy steel can be laser welded well, but stress should be relieved and cracks should be avoided.

Third, stainless steel.

In general, stainless steel welding is easier to obtain better joints than traditional laser welding. Due to the high speed of laser welding and the small heat affected zone, the overheating phenomenon of stainless steel welding and the adverse effects of large linear expansion coefficient can be reduced, and laser welding has no defects such as pores and inclusions. Compared with carbon steel, stainless steel has low thermal conductivity, high energy absorption rate, and melting efficiency is easier to obtain deep penetration and narrow welds. Laser welding of thin plates with low-power laser welding can obtain connectors with good appearance and smooth and beautiful laser welding.

Fourth, copper and copper alloys.

Laser welding of copper and copper alloys is prone to the problem of unfused and non-laser welding. Select a heat source with concentrated energy and high power. Preheating measures are used for workpieces with thin thickness or small structural rigidity, and no deformation is prevented. When the measures are taken, large deformation is likely to occur after laser welding, and copper and copper alloys that are prone to laser welding stress when the welded joint is limited by large stiffness are prone to thermal cracks during laser welding.

Five, aluminum alloy laser welding.

When laser welding aluminum sheet and aluminum sheet, the biggest difficulty is that it can reflect the Co2 laser beam of 10.8pon wavelength. Aluminum is an excellent conductor of heat and electricity. High-density free electrons have good reflectivity. The reflectivity of the starting surface is more than 90%, which means that the initial energy of deep penetration welding is less than 10%. To guarantee the power density required at the start of laser welding, high input power is required, creating small holes.

6. Laser welding process of magnesium alloy.

Its density is 36% lower than that of aluminum, and it is a high specific material that attracts much attention. Using YAG laser continuous C02 and C02 laser welding, in AZ31B-H244 alloy (3.27% Al, 0.79% Zn), the average power is 0.8kW, 5ms, 120Hz, 300mm/s, With a focus size of 0.42mm, C02 laser welding has good melting properties.

Seven, high-strength low-alloy steel.

Laser welding of low-alloy high-strength steel can obtain the same mechanical properties as the base metal. HY-130 steel is a typical low-alloy high-strength steel that has been quenched and tempered, with high strength and good crack resistance. During laser welding by conventional welding methods, the laser welding structure and HAZ structure are coarse and partially fine original structures, and the joint toughness and anti-interference ability are much lower than those of the base metal. The laser welding and HAZ metal structures are particularly sensitive to cold cracks in the laser welding state. .
