Can you Weld Wrought Iron to Mild Steel?

When it comes to welding, there are endless possibilities but many questions too. One of the most frequently asked questions is whether or not it’s possible to weld wrought iron and mild steel together. If you’ve ever wondered if this type of combination is a viable option for your project, keep reading! We’ll explore the fundamentals behind these two materials and help you determine whether or not they can be successfully welded together. From optimal temperatures to safety tips, we have everything you need to know about combining wrought iron with mild steel in one handy blog post. Read on and get your projects off the ground without any unnecessary hiccups along the way!

What Is Wrought Iron?

Wrought iron is an iron alloy with a carbon content lower than 2%, with a few other elements like manganese and silicon. It’s malleable when heated, so it can be shaped into ornamental gates, railings, furniture and other intricate structures. Wrought iron is the strongest and most durable type of metal used in architecture – it will last for centuries without corroding if maintained properly.

What Is Mild Steel?

Mild steel is a low-carbon alloy steel that contains between 0.05–0.25% carbon and up to 0.4% manganese, making it a relatively ductile material that is highly suitable for general engineering applications such as automotive components, construction materials, pipes and tubes, shipbuilding components, railway wagons, bridges etc. It is also particularly resistant to rusting due to its high manganese content while still being reasonably affordable compared with higher alloyed steels on the market today.

Welding Process

Preheat the Metal

The first step in welding wrought iron to mild steel is to preheat the metal to approximately 500°F (260°C). This helps to reduce the risk of cracking and ensures that the metals will bond properly. It is important to ensure the preheating temperature is not too high, as this can cause warping and other issues.

Clean the Metal

Once the metal has been preheated, it must be thoroughly cleaned before welding. This involves removing any dirt, rust, or other debris from the surface of both pieces of metal. A wire brush or sandpaper can be used for this purpose. It is also important to remove any paint or other coatings from both pieces of metal before welding.

Select an Appropriate Welding Process

The next step in welding wrought iron to mild steel is selecting an appropriate welding process. The most common processes used for this type of weld are shielded metal arc welding (SMAW), gas tungsten arc welding (GTAW), and gas metal arc welding (GMAW). Each process has its advantages and disadvantages, so selecting a process that best suits your needs and experience level is important.

Prepare the Joints

Once you have selected a welding process, you must prepare the joints for welding by grinding away any slag or scale from both pieces of metal and ensuring that they fit together properly. If necessary, you may need to use a filler rod when preparing the joint in order to fill any gaps between the two pieces of metal.

Weld Together

Finally, you can begin welding together your wrought iron and mild steel pieces using your chosen process. Be sure to follow all safety procedures while doing so and wear appropriate protective gear such as gloves, goggles, and a face shield or helmet with a hooded visor when necessary.


Welding wrought iron to mild steel is certainly possible, however there are some considerations you should take into account before beginning a welding project. It’s important to understand the differences between the two materials and choose the right welding methods for each to ensure a strong and durable bond. You’ll also need to select the correct welding equipment. Welders who have experience working with both metals may find it easier to decide on the optimal welding technique, while those without prior experience could benefit from seeking advice from an experienced welder or professional metalworker. With careful preparation and the right expertise, you can create strong welds between mild steel and wrought iron for any number of projects.
