Welding rod type

(l) According to the purpose of the electrode:

l) Low carbon steel and low alloy high strength steel welding rod (referred to as structural steel electrode).

2) Stainless steel electrode.

3) Surfacing electrode.

4) Low temperature steel electrode.

5) Cast iron welding rods.

6) Nickel and nickel alloy electrodes.

7) Copper and copper alloy electrodes.

8) Aluminum and aluminum alloy welding rods.

(2) According to the characteristics of the slag after melting the electrode of the electrode:

l) Acidic electrode.

   Generally used to weld low carbon steel and less important steel structures.

2) Alkaline electrode.

    Alkaline slag has complete deoxidation, and can effectively eliminate sulfur in weld metal, and less burning of alloying elements. Therefore, the weld metal has good mechanical properties and crack resistance, and can be used for alloy steel and important carbon steel. Structural welding.
