The Principle of Laser Automatic Welding Machine

 

Automatic laser welding machine is a kind of equipment that utilizes laser technology for welding. The principle is to use the laser generated by the laser beam, through the collimation, focusing and other optical components to focus the laser beam to the welded joints, high energy density instantaneous heating of the weldment, so that the welded joints localized melting, and then cooled and solidified, so as to achieve the welding.


Specifically, laser automatic welding machine mainly includes laser source, optical system, welding head and control system and other major components.


The laser source is the core component of the laser automatic welding machine, usually using solid-state lasers or semiconductor lasers as the laser generator. The laser source generates a laser beam with specific wavelength and power through the input of electric energy or optical energy.


The optical system mainly includes the laser beam delivery system and the focus control system. The laser beam delivery system utilizes optical components such as collimating mirrors and mirrors to collimate, focus and transmit the laser beam so that the laser beam is accurately focused on the welded joint. The focus control system adjusts the focus position and depth of focus according to the specific shape and size of the welded joint to ensure accurate and stable welding results.

Control Principle of Laser Automatic Welding Machine

 

 

The control principle of laser automatic welding machine mainly relies on the precise control of laser focus position, welding speed, laser power and protective atmosphere, through real-time monitoring and energy feedback system to ensure the stability and reliability of the welding process, in order to achieve the optimal depth of fusion, minimum heat-affected zone and ideal welding operation. This ensures a stable and reliable welding process through real-time monitoring and energy feedback system to achieve the optimal depth of fusion, the smallest heat-affected zone and ideal weld shape.


The core of an automated laser welding machine is a highly concentrated beam of energy generated by a laser light source, which is usually generated by a laser generator and focused into a very small area by a sophisticated optical system. The laser welding process is divided into two basic types depending on the energy density: thermal conduction welding and laser deep fusion welding. In the thermal conduction welding mode, when the laser power density is low, the laser energy is mainly transferred to the internal material through thermal conduction, which is applicable to the welding of thin sheet materials or precision parts, and the welding speed is relatively slow but the precision is high. The welding speed is relatively slow, but the precision is high. In the laser deep melting welding mode, with the increase of laser power density, the laser beam can rapidly heat the material surface to the vaporization temperature, forming the "hole effect", achieving deep melting, high speed and high precision. The laser beam can rapidly heat the material surface to vaporization temperature, forming a "hole effect" and realizing deep fusion depth, high speed and large depth-to-width ratio welding.


In order to realize precise control, the laser automatic welding machine is also equipped with a control system, through the laser power, wavelength, pulse and other parameters of the adjustment, to control the welding temperature, depth, speed and other parameters by adjusting the laser power, wavelength, pulse and other parameters to obtain the desired welding effect. This control principle ensures high efficiency, precision and low heat impact of the laser welding machine, which is widely used in automotive, aerospace, electronics and other fields.
