    1.Scope of application of cold welding repair machine:

    Cold welding repair machine is a professional precision repair welding equipment for pinholes, sand holes, pores, cracks, bumps, scratches, pits, surface wear of mechanical parts, mold wear and other small defects of castings. It is widely used in mold industry, casting industry, electrical appliance manufacturing industry, medical equipment, automobile, shipbuilding, boiler, construction, bridge construction and other industries.

    2.Applicable materials for cold welding repair machine:

    The cold welding repair machine uses ordinary welding wire as a supplementary material, and the range of welding wire that can be clamped is between. The materials that can be welded and repaired are: gray iron, ductile iron, stainless steel, carbon steel, die steel, aluminum, aluminum alloy, and other metals that can be repaired as long as they are conductive.

    3.Working principle of cold welding repair machine:

    1) The principle of the cold welding repair machine is to use the charging capacitor, with a cycle of 1 10 3 10 seconds, and an ultra-short time discharge of 5 10 6 10 seconds, the contact part between the electrode material and the workpiece will be instantly heated to 8000 10000, and the molten metal in the state of plasma quiet grinding will transition to the surface of the workpiece in a metallurgical way. Due to the alloying effect with the base metal, it spreads to the inside of the workpiece, melts and infiltrates, and forms a diffusion layer, which obtains a high-strength bond.

    2) The principle of cold welding (low heat input): Why can cold welding be realized? Because the discharge time is extremely short compared to the next discharge interval, the machine has enough relative stopping time, and the heat will be diffused to the outside through the workpiece primitive, so there will be no heat accumulation in the machined part of the workpiece.

    Although the temperature of the workpiece is almost at room temperature, the temperature of the electrode tip can reach about 10,000 due to instantaneous melting.

    3) High bonding strength: When using the CNC intelligent cold welding repair machine for repair surfacing welding, the heat input is low, why is the bonding strength still very large? This is because the wire instantly generates molten metal droplets that transition to the contact point with the base metal, and at the same time, due to the high temperature of the plasma arc, a strong diffusion layer is formed deep in the surface layer as if it had taken root, showing high adhesion and not falling off.

    4.Cold welding repair machine repair features:

    1) Low-heat and normal temperature welding, the matrix does not heat, does not produce thermal deformation, the metallographic structure near the welding repair point remains unchanged, there is no stress, no cracks, no hard spot hardening, and does not affect the machining performance.

    2) Simple operation, one machine for multiple purposes. In addition to the surfacing repair function, tungsten carbide and other tungsten carbide surface coating enhancement can also be performed.

    3) Argon gas has good protective tightness, high welding strength, metallurgical bonding, re-solidification after the compound and the substrate are melted at the same time, and the bond is firm, dense and does not fall off. After welding, it can be used for various machining such as turning, milling, planing, and grinding.

    5) Rotary self-destructive electrode deposition surfacing welding, easy to operate and high work efficiency.

    6) Environmental protection and pollution-free. No harmful gas is generated, it can be directly held, Qishi bucket eyesight, accurate welding position, small welding repair point, and small post-welding trimming amount.

    7) The welding repair process is the repeated melting and accumulation of high-frequency welding repair points, regardless of the size of the defect, as long as the pen tip can touch the place can be repaired.

    8) Pure metal repair, no welding traces, welding repair effect meets the quality inspection standards.

    The cold welding repair machine, also known as the die cold welding machine, can release the welding energy in a very small range in an instant, so that the supplementary material is completely welded to the workpiece. The overall heat generation of the workpiece is very small, so it can avoid the shortcomings of traditional welding, such as deformation, cracks, and discoloration, and is especially suitable for repairing fine workpieces and workpieces that cannot be welded at high temperatures.

    During the use of the mold, the mold groove gradually wears out and the size exceeds the tolerance range, or serious thermomechanical fatigue cracks occur locally, or the wear is uneven. This affects the surface quality of forgings, and even makes it difficult to mold. The traditional mold repair method either treats the vernier but does not cure the root cause and cannot be completely repaired, or it is the use of electric welding, which is not easy to grasp, and the electric welding heats up, which may cause the scrapping of the whole set of molds.

    Jielite mold repair cold welding machine adopts cold welding composite repair process, which can completely repair the mold damage of the Qin key pin, and at the same time, ensure that the accuracy of the mold is not affected, and the bright is in the middle, because we choose special alloy materials in the material, the local performance of the repaired mold can exceed the new product.
