OEM Porous Metal Stainless Steel Filter Vacuum Electron Beam Welding Sintered Metal Filter Valve Filter

Product Describe

Electron beam welding is used in many industries such as aerospace, atomic energy, automotive, and electrical and electric instrumentation because of its advantages of no electrode, low oxidation, good process repeatability, and low thermal deformation. The basic principle of electron beam welding is that the cathode in the electron gun emits electrons due to direct or indirect heating, and the electrons are accelerated by the high-voltage electrostatic field and then focused by the electromagnetic field to form an electron beam with extremely high energy density, with this electron beam to bombard the workpiece, the huge kinetic energy is converted into heat energy, so that the workpiece at the weld melts and a molten pool is formed, thus realizing the welding of the workpiece.

Performance requirements

The high-voltage power supply for the electron beam welding machine must be chain-protected with relevant systems during operation, mainly the vacuum chain, cathode chain, gate valve chain, focus chain, etc., to ensure equipment and personal safety. The high-voltage power supply must comply with EMC standards and have a soft start function to prevent the impact of sudden closing on the power supply.

High reliability, indoor equipment, continuous operation, appearance to meet the requirements of industrial equipment, easy maintenance, etc.

Features:
    1. The perfect combination of vacuum electron beam welding and sintered metal filter material, forms a new welding process.
    2, the element selects new filter material stainless steel sintered mesh as filter material, which itself has sufficient strength and rigidity, thus rejecting the skeleton commonly used in cartridge products and solving the problem of difficult deburring.
    3. no foreign matter is generated during processing, solving the problem of its own pollution and ensuring the cleanliness of the system.
    4、The choice of sintered mesh as the filter material makes the element washable and regenerable repeatedly, and the life span is greatly extended.
    5. Vacuum electron beam welding can melt through the base material, so the strength of the weld is high, the weld does not oxidize, no need for follow-up treatment, and the overall beauty is beautiful.
    6. The overall structural strength, structural integrity, and dimensional accuracy of the filter element far exceed those of ordinary welding processing means.
