Technical Features

Laser welding can be used in continuous, pulse energy output, according to energy density, laser welding into the laser heat conduction welding and laser deep welding two modes. Typically, the laser energy density is less than 10^4~10^5 W/cm² of heat conduction welding, the laser incident energy density is low, the workpiece absorption of energy is insufficient to make the metal vaporization, only melting occurs, then the metal melted by the laser radiation absorption and heat conduction is carried out. Since there is no steam pressure, the heat flux when the melt depth is generally shallower. The laser energy density is greater than 10^5~10^7 W/cm2 for deep penetration welding, the energy density level of the laser in a very short period of time so that the heating area of the metal vaporization, resulting in the liquid melt pool formed in a small hole, called the spoon holes. The beam can be directly into the keyhole inside, through the keyhole of heat transfer, obtain a greater Weld depth.

 The characteristics of laser welding compared to traditional arc welding methods are:

High energy density, resulting in a large weld depth-to-width ratio

 Minimal welding deformation

High welding speed and efficiency

Precisely adjustable energy

Compatible with a wide range of materials, including dissimilar materials

The beam can be customized as needed
