Example Embodiment
[0014] Embodiment 1: A composite welding electrode, comprising a metal core and a coating, the metal core including a fixedly connected working part and a clamping part, the coating is coated on the outer surface of the working part, and the material of the working part It is an iron-based alloy, the material of the clamping part is an aluminum-based alloy, and the coating contains the following components: 2.8% carbon, 3.0% nickel, 0.9% molybdenum, 3.8% manganese, and the balance is iron oxide ; The above percentages are weight percentages.
[0015] The composite electrode of this embodiment only needs to be partially improved on the basis of the existing manufacturing process during manufacture, nickel, molybdenum, and manganese are added to the original components of the coating, and the carbon content in the coating is adjusted to 2.8% . The composition of the core remains unchanged.
[0016] The manufacturing method of the above composite electrode includes the following ste...
Example Embodiment
[0024] Example 2: Basically the same as Example 1, the difference is the composition of the drug skin, specifically:
[0025] The coating contains the following ingredients: 2.5% carbon, 2.75% nickel, 0.5% molybdenum, 3.0% manganese, and the balance is iron oxide; the above percentages are all weight percentages.
Example Embodiment
[0026] Example 3: Basically the same as Example 1, the difference is the composition of the drug skin, specifically:
[0027] The coating contains the following components: 3.0% carbon, 5.0% nickel, 1.2% molybdenum, 4.5% manganese, and the balance is iron oxide; the above percentages are all weight percentages.
