The best welding rod for cast steel depends on two main factors: the application of the weld and the type of base material.
There are many different types of welding rods available, including mild steel electrodes, stainless steel electrodes and nickel-based alloy electrodes.
Each welding rod has its specific features that must be considered in order to select the best rod for any given application.
Best stick welding Rods for Cast Steel Welding
6013 Welding Rod
6013 welding rod is a type of mild steel electrode that is commonly used for welding in the flat and horizontal positions.
It is known for its smooth arc action, easy slag removal, and high deposition rate. It is often used for welding sheet metal, structural steel, and other low-carbon steels. It is also suitable for welding in both AC and DC current.
7018 Welding Rod
For welding cast steel, 7018 welding rod may be a better choice than 6013 welding rod in term of high strength and low hydrogen content.
Note that Cast steel is similar to carbon steel with low carbon content, but it’s in a casting form.
7018 welding rod provides a deep penetration that can help to fill any porosity or voids in the cast steel, which is common in casting process.
7015 Welding Rod
7015 welding rod is a low hydrogen electrode that is similar to 7018, but it is designed to have a faster freezing slag, which allows for higher welding speeds and more penetration in welding.
This type of rod is highly popular among professionals due to its good weldability and high tensile strength.
It can be used in both manual and automated welding processes, making it very versatile and suitable for a welding cast steel.
The main advantages of using ER70S-6 TIG rod for cast steel welding include: good mechanical properties, low spatter characteristics, good impact resistance, great wetting action and improved bead appearance.
The low carbon content also results in better corrosion resistance compared to other wires.
Additionally, the deposits created by this type of rod are quite smooth which helps in reducing post-weld cleaning time.
Best MIG welding Rods for Cast Steel Welding
When it comes to MIG welding rods, there are many options available for cast steel welding. Two of the best rods are ER70S-6 and ER70S-2 wires.
These two wires offer excellent weld deposits that will enable you to make strong and reliable welds on cast steel materials.
The ER70S-6 wire is a copper coated mild steel wire with high levels of manganese and silicon that produces an incredibly strong weld deposit.
It also has higher amounts of deoxidizers, which help to reduce porosity in welds that may be exposed to moisture or corrosion over time.
The ER70S-2 wire is ideal for welding Cast Steel components since it has a higher amount of manganese and silicon with added titanium than the other rods, which gives it superior strength & ability to weld on rusty surfaces.
Best Gasless MIG welding wire for Cast Steel Welding
When selecting a gasless MIG welding wire, opt for one made from solid core flux-cored steel and designed specifically for cast steel applications.
Look for wires that are compatible with both AC and DC power sources and offer an excellent combination of strength and ductility, as well as smooth feeding characteristics and good slag removal.
E71T-8 and E71T-11 are gasless, self-shielded flux-cored wires that are commonly used for MIG welding low-alloy and carbon steels.
Both wires do not require an external shielding gas and can be used in a variety of positions.
E71T-8 typically provides a smooth, stable arc and a good bead appearance, while E71T-11 has a higher level of deoxidizers and provides a better penetration and less spatter than E71T-8.
The E71T-8, and E71T-11 gasless MIG wires are great options for performing cast steel welding because they can provide superior strength, excellent corrosion resistance, and good ductility in the welded areas.
