Different Types of Welding Rods

Dec 21, 2023


Welding rods are the sticks that welders use to join metals together. They can be of different types, like ones you throw away after using or ones you can use again. Welders pick from rods made for various metals such as carbon steel or aluminum.

The numbers on the rods give important details like which metal they're good for and how strong they make the welds. It's very important to handle these rods right by keeping them dry and wearing gloves so you don't get hurt.

When welding, it's key to choose just the right rod—this will make sure your weld is not only strong but also looks good wherever it is done. Among many types, 6010 rods dig deep into metal while 7018 makes super-strong bonds on lots of metals.

What is Welding Rod?

Welding rods, also known as electrodes, are welding materials that are melted and injected during stick welding operations. To use a welding rod, first connect it to your welding equipment, which will create an electric arc between the base metal and the welding rod. The powerful electric arc quickly melts the metal, allowing it to be fused for welding.

Types of Welding Rods

When it comes to welding, there are different types of rods that can be used. These include consumable versus non-consumable electrodes and various materials such as carbon steel, stainless steel, bronze, and aluminum.

Consumable vs. Non-Consumable Electrodes

In stick welding, you have two main types of electrodes: consumable and non-consumable rods. Consumable rods melt during the welding process to help join metal parts together. Shielded metal arc welding rods are a common example of consumable electrodes.

They add filler material to your weld as they burn away.

Non-consumable electrodes don't melt like consumable ones do. Instead, they help create the arc that melts the metal you want to join but stay intact themselves. Tungsten Electrode is a popular material for non-consumable welding rods because it can handle high temperatures without melting.

Now let's look at different materials we use for these electrodes and how each one works with various metals.

Different Materials (Carbon Steel, Mild Steel, Stainless Steel, Bronze, Aluminum)

Welding rods are designed to work with specific materials. Each type of metal requires a different welding rod to ensure a strong bond. For carbon steel, mild steel, and stainless steel, you'll need the appropriate matching welding rod for each type.

Bronze and aluminum also require their own specific welding rods tailored to their composition.

When working with these different materials, it's crucial to select the right welding rod for the job. Using the wrong rod can lead to weak welds or even damage the base material itself.

Welding Rod Number System

Understanding the welding rod number system is crucial for selecting the right electrode for your welding project. Different codes and numbers indicate specific characteristics, so it's important to know what they mean.

This section will cover popular types like 6010, 6011, 6013, 7018, and 7024 to help you make informed decisions.

Meaning and Codes

The number on a welding rod tells you about its characteristics. For example, a 6010 electrode is great for deep penetration. The first two digits indicate the tensile strength of the weld it can produce in thousands of pounds per square inch.

The third digit, when read together with the last two, shows the welding position and the type of current to use.

Different types have different meanings, such as 7018 which is used for low-hydrogen applications or 6013 which works well with low-amp machines. Understanding these codes helps you choose the right rod for your specific welding needs and ensures strong and quality welds.

Popular types (6010, 6011, 6013, 7018, 7024)

Popular welding rod types include 6010, 6011, 6013, 7018, and 7024. Each type suits different purposes like repair, fabrication, or maintenance. The numbers indicate specifics about the electrodes such as arc stability and strength.

For instance, the 6010 is excellent for deep penetration while the 7018 offers high-quality welds for various metals. Understanding these types helps you choose the right one for your specific welding needs.

Choosing the Right Welding Rod

Consider the metal type, desired appearance, strength requirements, and welding position when choosing the right welding rod. Handle with care to avoid damage or injury while working with welding rods.

Considerations Based on Metal Type, Appearance, Strength, and Welding Position

When choosing welding rods, it's essential to consider the metal type you're working with. Different metals require specific welding rods for optimal results. Additionally, take into account the appearance and strength of the weld you want to achieve, as well as the position in which you'll be welding.

Each factor plays a crucial role in selecting the right welding rod for your project and ensuring a successful outcome.

Now let's delve into understanding the Welding Rod Number System to gain insights into its meaning and codes before exploring popular types such as 6010, 6011, 6013, 7018, and 7024 that are widely used across various welding applications.

Precautions While Handling

Before you start handling welding rods, it's crucial to ensure that your hands and the rods are dry. Moisture can lead to weld contamination or cause electric shock. Always wear welding gloves and use proper storage to prevent damage or corrosion of the rods.

Additionally, make sure to inspect the welding rods for any defects before use, as using damaged rods can result in poor weld quality.

When choosing the right welding rod for your project, it is important to consider various factors such as metal type, appearance, strength, and welding position. It’s important not only for achieving a successful weld but also for ensuring safety during the welding process.


In conclusion, different welding rods serve specific purposes and are crucial for various welding applications. Understanding the types of welding rods available, including consumable and non-consumable electrodes, is essential to make informed choices.

Additionally, being familiar with the welding rod number system and considerations for choosing the right rod based on metal type, appearance, strength, and welding position is vital for achieving successful welds.

Overall, having a comprehensive knowledge of different types of welding rods empowers welders to deliver high-quality work while ensuring safety and efficiency in their projects.
