Welding Rod for Manganese Steel

One of the most important decisions you will make when welding manganese steel is which welding rod to use. The right welding rod can mean the difference between a good weld and a poorly done or even dangerous one. This article will help you select the best welding rod for your manganese steel project.


What is Manganese Steel?

Manganese steel is a strong, high-quality alloy with excellent wear resistance. It’s often used in construction, mining, and other heavy-duty applications because it can withstand extreme temperatures and impacts. When it comes to welding this material, however, there are some considerations you need to make to ensure that your work is safe and reliable.

Welding Rod for Manganese Steel

The first thing to consider when selecting a welding rod for manganese steel is if it will be used for MIG (Metal Inert Gas) or TIG (Tungsten Inert Gas) welding. For MIG welding, an E7018 electrode works best; this type of electrode has a low hydrogen content, so it minimizes cracking and porosity in the finished weld. For TIG welding, you should use an ER70S-6 or ER90S-B9 filler wire; these are both low-alloy steels that offer good penetration and strength for manganese welding projects.

The next factor to consider when choosing a welding rod for manganese steel is its diameter size. Different thicknesses of manganese require different sizes of rods; thinner sheets may require rods as thin as 1/32″, while thicker sheets may need rods as thick as 5/32″ or even 3/16″ in diameter. Choosing the right size rod for your project will help ensure optimal results during the welding process.

Finally, be sure to pick the correct type of coating for your specific application needs; some rods come with zinc coatings while others may have copper coatings – each with their own advantages depending on your job. Zinc coatings provide better corrosion resistance while copper coatings are more suitable for higher temperature applications such as heat treating processes.

How to Weld Manganese Steel?

Welding manganese steel can be a tricky task as it has a higher melting point than other metals, making it difficult to join pieces together. You will need the right protective gear in order to avoid any burns or safety hazards. The most successful method for welding manganese steel is to use the gas metal arc welding process; this involves an inert gas like argon or carbon dioxide being released over the welded area. A wire-feed that releases an electric arc is also necessary and should be used with a low amperage current and a short duration power cycle. In addition, you should preheat and post heat the steel pieces as these processes allow for better absorption of the filler material and create a strong bond between two pieces. By following these steps, you can successfully weld manganese steel and ensure your project longevity.


Selecting the right welding rod for your manganese steel project can be tricky but with careful consideration you can find the perfect solution that meets your needs and ensures a successful outcome every time! Considering factors like MIG vs. TIG use, diameter size, and coating type, you can make an informed decision that will yield professional results! With the proper selection process in place, there’s no reason any welder shouldn’t be able to succeed when working with manganese steel!
