Definitions

  • the present invention relates to a highly intelligent laser welding robot system.
  • Laser welding is a highly efficient precision welding method that utilizes a high energy density laser beam as a heat source.
  • Laser welding is one of the important aspects of the application of laser material processing technology. In the 1970s, it was mainly used for welding thin-walled materials and low-speed welding.
  • the welding process is heat-conducting type, that is, laser radiation heats the surface of the workpiece, and surface heat is diffused to the inside through heat conduction, by controlling the width, energy, peak power and repetition frequency of the laser pulse.
  • the parameters are such that the workpiece is melted to form a specific molten pool. Due to its unique advantages, it has been successfully applied to precision welding of small and small parts. China's laser welding is at the advanced level in the world.
  • Laser welding can be achieved by continuous or pulsed laser beams.
  • the principle of laser welding can be divided into thermal conduction welding and laser deep welding.
  • the power density is less than 104 ⁇ 105 W/cm2 for heat conduction welding.
  • the melting depth is shallow and the welding speed is slow.
  • the power density is greater than 105 ⁇ 107 W/cm2 ⁇ , and the metal surface is concave into "holes" under the action of heat to form deep fusion welding.
  • the welding speed is fast and the aspect ratio is large.
  • the principle of thermal conduction laser welding is: laser radiation heats the surface to be processed, surface heat is diffused to the inside through heat conduction, and the workpiece is melted by controlling laser parameters such as width, energy, peak power and repetition frequency of the laser pulse to form a specific molten pool.
  • Laser welding machines for gear welding and metallurgical sheet welding mainly involve laser deep penetration welding.
  • Light deep penetration welding generally uses a continuous laser beam to complete the material connection.
  • the metallurgical physical process is very similar to electron beam welding, that is, the energy conversion mechanism is completed by a "key-hole" structure. Under high enough power density laser illumination, the material evaporates and forms pores.
  • This vapor-filled hole is like a black body, which absorbs almost all of the incident beam energy.
  • the equilibrium temperature in the cavity reaches about 2500 °C. Heat is transferred from the outer wall of the high-temperature cavity, melting the metal surrounding the cavity.
  • the small hole is filled with high-temperature steam generated by continuous evaporation of the wall material under the irradiation of the light beam, and the small holes surround the molten metal.
  • the liquid metal is surrounded by solid materials (and in most conventional welding processes and laser-conducting welding, energy is first deposited on the surface of the workpiece and then transferred to the interior by transfer). The liquid flow outside the pore wall and the surface tension of the wall layer are maintained and maintain a dynamic balance with the vapor pressure continuously generated in the pore cavity.
  • the beam continuously enters the small hole, and the material outside the small hole flows continuously.
  • the small hole is always in a flowing stable state. That is, the small holes and the molten metal surrounding the walls of the holes move forward with the advancement speed of the leading beam, and the molten metal fills the gap left after the small holes are moved and condenses, and the weld is formed. All of the above processes happen so quickly that the welding speed is easily reached several meters per minute.
