Best Welding Rod for En19 Material

Welding is a vital process in the manufacturing industry, and welders often require the right welding rod to get the job done efficiently and effectively. The En19 material is a high-tensile alloy steel commonly used in the engineering and manufacturing sectors. Choosing the right welding rod for this material is critical to ensure that the welds are strong and have excellent quality. In this blog, we will explore the best welding rods for En19 material and how to choose the right one for your welding project.

Understanding En19 Material

En19 material is a chromium-molybdenum steel alloy that typically has a tensile strength ranging from 700 to 850 MPa. This material commonly produces gears, shafts, and other machine components that require high strength. En19 material requires welding techniques that are robust enough to handle the high heat generated without losing strength and quality.

Choosing the Best Welding Rod

The first step in choosing the best welding rod is to ensure it matches the welding process you intend to use. The most common welding rod used for En19 material is the 7018 welding rod. It’s known for its ability to handle high amperage and its excellent tensile strength. En19 material also works well with 6010, 6011, and 6013 welding rods if you need an alternative.

Tips for Welding En19 Material

Welders often face challenges when welding En19 material, particularly with thermal cracking. Preheat the material to at least 200 degrees Fahrenheit before welding to prevent thermal cracking. You can also use a low-hydrogen welding rod, such as 7018, to reduce the moisture content and prevent hydrogen embrittlement. Another tip is to use a proper welding technique, such as running a stringer bead or weave pattern, to manage the heat and reduce the risk of warping.

Factors to Consider When Choosing a Welding Rod

The following are critical factors to consider when choosing a welding rod for En19 material:

The thickness of the material

The thicker the material, the more amperage required, which calls for a welding rod with a higher amperage rating

The chemical composition of the material

Knowing the chemical composition of the material helps you choose the welding rod that is compatible with it.

The welding environment

The environment in which welding takes place can influence the choice of welding rod. For example, welding enamel surfaces or areas with high humidity requires a low hydrogen welding rod that reduces hydrogen embrittlement.


Choosing the right welding rod for En19 material is critical to ensure that the welds are strong, high-quality, and long-lasting. When selecting a welding rod, it’s essential to consider factors such as the thickness of the material, the chemical composition of the material, and the welding environment. The 7018 welding rod is the most popular En19 material, but you can also use 6010, 6011, and 6013 welding rods as alternatives. Following these tips and guidelines, you can choose the best welding rod for your welding project and achieve excellent results that meet your needs.
