What is the best welding rod for GI Pipe?
GI pipes are used extensively in the industrial sector, and welding these pipes requires specific welding rods. Welding rods are consumable electrodes that conduct electric current to weld two pieces of metal together.
The best welding rod for GI Pipe depends on several factors such as the thickness of the pipe, type of joint, and welding technique.
The choice of welding rod for a GI (galvanized iron) pipe would depend on several factors such as the type and thickness of the pipe, the welding technique used, and the welding position. However, in general, it is recommended to use an AWS E6011 or E6013 & E7018 electrode for welding GI pipes.
So, which is the best rod for GI Pipe Welding?
Generally, E6013 and E7018 welding rods are used for GI pipe welding. One of the most popular welding rods for GI pipes is E6013. This electrode is an all-purpose welding rod that can be used on various types of steel, including galvanized iron (GI) pipes.

It provides excellent penetration and produces a smooth weld bead with minimal spatter. Furthermore, it has a relatively low amperage requirement, making it easy to use even by novice welders. E6013 is a versatile electrode that provides a smooth arc with minimal spatter.
It is suitable for thin pipes and can be used in all positions – flat, horizontal, vertical, or overhead.
E6011 electrodes are designed for use with direct current (DC) and are suitable for all positions. They have excellent penetration and can weld through rust, oil, and other contaminants. This makes them a good choice for welding GI pipes that may have surface contaminants.
On the other hand, E7018 is ideal for thicker pipes as it creates a strong weld with excellent tensile strength. It requires higher amperage to operate but produces very little slag.
