[0047] A high vacuum electron beam welding device 4 is provided at the top of the outer portion of the vacuum chamber 14.

[0050] During the welding process, the workpiece is firstly welded by the low vacuum laser welding system, and then the high vacuum electron beam welding system is used for recheck welding to improve the quality and performance of the weld. During welding, the workpiece to be welded is first fixed and clamped by the workbench 33, and the workpiece is moved into the vacuum chamber 14 by the linear lead-out mechanism, and the hatch 13 is closed; the vacuum chamber 14 is evacuated to a low vacuum environment by the low vacuum pump group 12, the gantry moves and adjusts the position through the ground rail 22, and the inverted welding six-axis robot 23 is moved and raised and adjusted.

The electron gun body 411 beats the electrons into a beam, and the kinetic energy of the beam is converted into heat energy to melt the surface material for fine welding.

[0051] For example, for high-temperature alloy parts used in the aerospace field, low-vacuum laser welding is used for quick connection first, and then high-vacuum electron beam welding is used for fine processing, which can significantly improve the strength and corrosion resistance of the welds and meet the operating requirements of aircraft in extreme environments. In automobile manufacturing, for the welding of structural parts such as frames, this dual-source double-check welding method can ensure the firmness and stability of the welds and improve the overall safety and reliability of the car.

[0052] In addition, in the electronics industry, for the welding of microcircuit boards and precision electronic components, the equipment can achieve high-precision, non-destructive welding effects to ensure the performance and stability of electronic equipment. In the energy field, such as the manufacture of solar panels and the production of nuclear reactor components, the equipment can meet the stringent requirements for welding quality and improve the service life and safety of energy equipment.
