    weld nickel alloys electrodes can produce arc under a small current and keep to work under a small current.It also works well under a low direct current.It is better for welding pipeline and thin and small parts,welding continuosly,welding for a special number parts.


      What does weld nickel alloys electrodes welding method look like?

      A preparation method for weld nickel alloys electrodes

    The preparation method of the weld nickel alloys electrodes further includes the following steps: pre-treatment of the prepared nickel conductor electrode is performed by acidic electroless nickel plating or alkaline electroles nickel plating;

 

        Wherein, the method includes the following steps:

       1、Ni, boron, aluminum, zinc powder is mixed according to a predetermined ratio, the mixture is pressed at a pressure of 6. 0-9. 0 tons / cm2, the pressure of the knot will be obtained in 2. 40-3 33Pa vacuum environment, 1200-1300 °C temperature in the heat 8-10 hours, after cooling the crushing block to 80-120nm, obtained nickel alloy powder;

      2. The nickel alloy powder, the glass powder, the ethyl cellulose, and the terpineol binder are mixed in a predetermined ratio to obtain a nickel slurry, wherein the glass powder is made of MgO, CaO, A1203, Si02, B203, PbO. Made by crushing after melting;

  The prepared nickel paste was printed on an alumina substrate and dried, and finally sintered in air to obtain a nickel conductor electrode.

     3, wherein, the predetermined proportion of the nickel, boron, aluminum, zinc powder mixture: by weight percentage, boron powder 1. 〇_8. 0,0. 1-1. 0, zinc powder 0. 3-3 . 0 Peaceful measure of silver powder, the sum of the components is 100%.

The sintering temperature is 850-1000°C.

The particle size of nickel powder is < 30 μm.

      The predetermined proportions of nickel alloy powder, glass powder, ethyl cellulose and terpineol binder are as follows: nickel alloy powder 70-80, glass powder 5-10, ethyl cellulose and terpineol, in percent by weight. Adhesive 10-25.

 

       The glass powder was made by melting MgO, CaO, A1203, Si02, B203, PbO and then pulverized into concrete: 2-5% Mg0, 3-5% Ca0, 5-10% A1203 in percentage by weight. 10-23% of SiO2, 13-20% of B20 3, and 37-67% of PbO were mixed and melted at a temperature of 1300C to obtain a glass frit;
