What materials are welding rods mainly used for welding?

1. Carbon steel welding

Carbon steel is a common metal material widely used in various fields. Carbon steel electrodes are usually used for welding carbon steel. This type of electrode is mainly used for low and medium strength carbon structural steel, plates, angle steel, flat steel, etc. Commonly used carbon steel electrodes include E6010, E6011, E7018 and other specifications.

2. Low alloy steel welding

Low alloy steel includes a series of steel types, which contain a certain proportion of alloy elements, such as manganese, chromium, molybdenum, titanium, etc. Low alloy steel welding requires the use of low alloy steel electrodes. The main purpose of this type of electrode is to weld structural parts such as automobiles, bridges, buildings, and ships. Commonly used low alloy steel electrodes include E7018, E8018 and E9018.

3. Stainless steel welding

Stainless steel is a special steel with excellent oxidation and corrosion resistance. Stainless steel welding requires the use of stainless steel electrodes. The main function of this type of electrode is to weld structural parts with stainless steel as the base material, such as petrochemicals, food processing, medical equipment and other fields. Commonly used stainless steel welding rods include E308, E309, E316 and other specifications.

4. Nickel alloy welding

Nickel alloy is a special metal material with excellent high temperature strength and corrosion resistance. Welding nickel alloy requires the use of nickel alloy welding rods, which are mainly used for welding structural parts in high temperature corrosion environments, such as aerospace, petrochemical, nuclear power and other fields. Commonly used nickel alloy welding rods include ENiCrMo-2, ENiCrFe-3, etc.

In general, different materials require different welding rods. The choice of welding rod must be determined based on multiple factors such as material type, thickness, and process requirements.
