Covered electrode specifications and models

The specifications and models of welding electrodes are mainly divided by diameter, and the common ones are 2.4mm, 2.8mm, 3.2mm, 3.6mm, 4.0mm, 4.8mm, 5.0mm, 5.8mm, 6.0mm, 7.0mm, 8.0mm, 10.0mm, etc.

In addition to the diameter, there are different types of covered electrode, such as low-carbon steel covered electrode, low-alloy steel covered electrode, stainless steel covered electrode, surfacing covered electrode, cast iron welding rod and copper-aluminum nonferrous metal covered electrode.

In addition, according to whether copper is plated or not, covered electrode can be divided into copper-plated covered electrode and non-copper-plated covered electrode. The purpose of copper plating is to prevent rust and improve conductivity.
