What kinds are there in covered electrode?

According to the nature of the coating, the coating covered electrode can be divided into acidic coating covered electrode and alkaline coating covered electrode.

According to the main chemical composition of covered electrode coating, covered electrode can be divided into: titanium oxide covered electrode, titanium oxide calcium covered electrode, ilmenite covered electrode, iron oxide covered electrode, cellulose covered electrode, low hydrogen covered electrode, graphite electrode and salt-based electrode.

According to the purpose, covered electrode can be divided into 10. ① Low carbon steel and low alloy steel covered electrode: mainly used for welding low carbon steel and low alloy structural steel. ② Bond and Cr-Mo heat-resistant steel covered electrode: mainly used for welding pearlite heat-resistant steel. ③ Stainless steel covered electrode: mainly used for welding heavy steel and heat-resistant steel.

④ Surfacing covered electrode: covered electrode used for surfacing to obtain wear-resistant or corrosion-resistant red hard surfacing layer. ⑤ Low-temperature steel covered electrode: It is used for structural welding under various low-temperature conditions, and its deposited metal has the required low-temperature working ability. ⑥ cast iron welding rod: Used for welding repair of cast iron.

⑦ Nickel and Nickel Alloy covered electrode: It can be used for welding nickel and its alloys, surfacing, repairing cast iron and welding dissimilar metals. ⑧ Copper and copper alloy covered electrode: used for welding copper and its alloys, dissimilar metals, cast iron, etc. Pet-name ruby silver and aluminum alloy covered electrode: used for welding aluminum and its alloys. Special purpose covered electrode: covered electrode for underwater welding or cutting.
