    • A brazing process of a smoke reducing filter for a diesel engine is provided to manufacture products at low cost by reducing working hour and process increasingly. A method for welding a smoke reducing filter(10) comprises a step for plating surface of a mesh(16) with plating liquid consisting of nickel and phosphorus; a step of assembling the mesh inside a cylinder(12); a step of injecting a smoke reducing filter passed through the former steps in the vacuum furnace or the hydrogen brazing furnace; and a step of brazing by heating with a heating condition having three steps.

    • PURPOSE: A method for brazing heat exchanger and a brazing treated heat exchanger are provided to improve workability and brazing efficiency by performing brazing work for a heat exchanger in a high-vacuum brazing furnace without using expensive filler metal. CONSTITUTION: A method for brazing a heat exchanger having a cooling pin and a separation plate includes a step of performing a nickel plating with respect to an upper surface and a lower surface of the separation plate. After forming an assembly by alternately stacking the cooling pin and the separation plate, the cooling pin and the separation plate are brazing-welded by heating the cooling pin and the separation plate through three steps. Then, the brazing treated assembly is naturally cooled and is rapidly cooled by supplying cooling gas thereto.
    • 目的:提供一种用于钎焊热交换器和钎焊处理的热交换器的方法,通过在高真空钎焊炉中对热交换器进行钎焊加工而不使用昂贵的填充金属来提高加工性和钎焊效率。 构成:用于钎焊具有冷却销和分离板的热交换器的方法包括相对于分离板的上表面和下表面进行镀镍的步骤。 在通过交替地堆叠冷却销和分离板形成组件之后,冷却销和分离板通过三个加热冷却销和分离板进行钎焊焊接。 然后,钎焊处理的组件自然冷却,并通过向其供应冷却气体而迅速冷却。
