    Electro-Spark Deposition Machine——Casting Defect Repairing Machine

     

     

     

    Principle

     

    Electro-spark deposition process is that release the high-energy stored in power supply between the metal electrode and the base metal by instantaneous high frequency, and through the gas ionization between the electrode material and the base metal to form multiple micro-arc channel, so that the surface of base metal generated instant heat micro-area, and the electrode materials was fusion welding into the base material matrix in micro electric field to form a metallurgical bond. Electro-spark process is repeated instantaneous high temperature in micro-area - the cooling process, it is different from the welding matrix no high temperature rise, and thus will not cause stress, deformation and so on.

     

    Feature

     

    Advanced technology: adopt unique chopper soft-switch technology, precision output control.

    Energy efficient: Although only 600W of power, but the speed of welding repair, the effect is more several times than the same 2000W cold welding.

    High welding strength: because with high output energy at the single point welding of this machine, every single point of welding material binding to matrix under the state of meltdown, to form a metallurgical, generating strong adhesion.

    The excellent effect to weld up on copper, aluminum: because the instantaneous high energy output, effective solution to the weld up of copper and aluminum and so on high-conductivity metal, overcome the shortcomings of welding not strong on the common electro-spark deposition.

    Without annealing and deformation on the matrix: the matrix is not need to preheat, and deposition process is repeated process that is instantaneous heat input - loss in micro-area, and the matrix will not too much temperature rise, so no deformation, undercut and residual stresses , does not produce local annealing.

    High repair precision: the deposition thickness is from a few microns to several millimeters, just grinding, polishing, after repairing, small or no color difference.

    A machine serves several purposes: can carry out deposition, surface hardening functions. Can weld up to ferrous metal (ductile iron, gray iron, stainless steel, etc.), non-ferrous metals (copper, aluminum, etc.).

    Environmental protection: no any pollution in the work process.

    Usability: anyone use easy, not need operating permit, can carry out deposition where welding difficult.

    Economy: immediately repair on site, improve production efficiency and cost savings.

    2.  Copper, Aluminum and Other nonferrous Metals Industry

     

    Non-ferrous metal pieces of various industries, such as aluminum parts of SF6 transformer in the power industry, and aluminum alloy cylinder block, cylinder cover, hub, aluminum alloy impeller in fan, aluminum radiator, etc. in automobile industry.

     

    Copper alloy plumbing valves, pipes, impeller, worm and other.

     

    3.  Model Industry

     

    Injection mold: weld up of wear, bumps, scratches, etc. of mold, eliminate overlap, burr of product.

     

    Die casting mold: the marks, loss, damage of zinc aluminum die casting, as well as the surface strengthening of the mould cavity and crossing pouring, to extending mold life.

     

    Copper alloy molds, aluminum alloy mold, nitrogen molds, etc.

     

    Suitable Weld Materials

     

    Because of ESD-05 unique control mode, the output energy is high, the control precision, so the suitable weld material is very more type except special weld rod used for electro-spark welding.  , other welding machine used in 1.2 3.2 mm in diameter of the article straight weld material most is to use, ordinary wire to medicine after skin can use.

    High-frequency discharge, ion conversion

    Machine power

    600W

    1200W-2500W

    Weld up efficiency

    As the work type that based on high-energy pulsed micro-particles melt conversion, greatly improved weld up speed, efficiency is more times than other cold welding machine

    Only ion conversion, low efficiency

    Weld up results

    No deformation, can be processed, high particle fusion welding combination rate, can through various process, test.

    No deformation, can be processed, general combination rate, poor copper solderability
