Most Common Stick Welding Rod Types and Uses

Stick welding is a versatile and widely used welding technique, and the right rod can make all the difference in the quality of your welds. There are several types of stick welding rods, each designed for specific applications and materials.

The most common types of stick welding rods are 6010, 6011, 6012, 6013, and 7018. Each type has its own unique characteristics and uses.

6010 rods are designed for all-position welding and are great for welding thick metal, but they can be more difficult to use for beginners. They have a high iron content, which makes them more prone to porosity.

6011 rods are similar to 6010 rods but have a lower iron content, making them easier to use and less prone to porosity. They are great for welding in all positions and are a popular choice among welders.

In stick welding, also known as shield metal arc welding (SMAW), the electrodes are consumable, meaning they melt into the weld during the process.

There are two main types of welding electrodes: consumable and non-consumable. Consumable electrodes are used during welding and melt into the weld, whereas non-consumable electrodes do not melt into the weld.

Stick welding electrodes are typically consumable and made of similar materials to the base metal, making them a crucial component in the welding process.

The numbers on a stick welding rod are like a secret code that tells you everything you need to know about the rod. Every stick electrode is unique, with some working well on rusty metal while others require clean steel.

The first two numbers identify the tensile strength of the electrode's filler material, measured in thousands of pounds per square inch. For example, the tensile strength of the E7018 rod is 70,000 pounds per square inch.

The third digit on the electrode identification number indicates the welding position the rod is suitable for. A 1 means the rod can be used in any welding position, while a 2 means it's only for flat and horizontal welding.

The fourth digit indicates the coating type and current used. Here's a breakdown of the most common coating types and currents:

For example, the E7018 rod has a coating type of low hydrogen potassium and iron powder, and can be used with AC, DC+, or DC- currents.

Rods ending in "8" are moisture-sensitive and should be stored in a rod oven to prevent damage.

There are several types of welding rods, each with its own unique characteristics and uses. For example, 6010/6011 rods are designed for deep penetration on dirty or rusted steel, pipelines, and farm equipment.

These rods demand skill, striking hot and splattering heavily, and are best used with DC-only (6010) or AC/DC (6011) power.

Other common types include 6013 rods, which are ideal for sheet metal, auto repair, and DIY projects, and 7018 rods, used for structural steel, bridges, and pressure vessels.

7018 rods are best used with AC/DC power, especially on a DC+ setting, and require oven-drying to prevent hydrogen cracking.

Here's a quick rundown of some popular welding rod types:

E6010 is a very popular and commonly used rod, and with good reason. It is easy to initiate the arc, deep penetrating, and given its spray-arc characteristics, allows for high travel speeds.

You'll often hear professionals recommend E6010 for its ability to weld well in all positions. If you're new to welding, this rod is a great starting point due to its ease of use.

The E6013 rod, on the other hand, is an old standby in some light-duty sheet metal applications. It's very forgiving of surface impurities like paint and rust, making it perfect for minor repairs.

Here are some common types of welding rods:

Remember, each type of rod has its own unique characteristics, and choosing the right one can make all the difference in the quality of your welds.

E7018 is a low-hydrogen welding electrode, developed to address sub-surface cracking issues in steel structures.

It's commonly used in structural steel welding and has a "fill freeze" classification, which means the weld puddle solidifies more slowly than fast freeze rods.

This results in welds with greater ductility, making it suitable for applications with cyclical stress, such as structural steel buildings and bridges.

E7018 can produce beautiful welds with tight, symmetrical ripples and a smooth contour, but it requires proper storage to prevent moisture absorption.

If not stored properly, E7018 rods can absorb moisture, leading to porosity in the welds.

Careful joint cleaning is essential, as E7018 is susceptible to porosity caused by surface contaminants like grease, paints, oils, or dirt.

E7018 typically requires DC power sources, although AC versions can be found in welding supply distributors.

E309L is a versatile welding rod suitable for welding common types of stainless steel. It's commonly used in maintenance and repair situations.

The "L" in E309L refers to low carbon, which is important because too much carbon in a stainless weld can greatly diminish corrosion resistance. This is a defining characteristic of stainless steel.

E309L offers a very high deposition rate and good crack resistance, making it a good choice if the specific grade of stainless is not known with absolute certainty.

It's also a popular choice for welding carbon steel to stainless steel, and many welders keep a small tube of 309 on hand for this reason.

As a beginner in stick welding, it can be overwhelming to figure out which electrode to use. The E6013 electrode is a great choice for new welders as it's easy to use and produces excellent welds.

Relatively inexperienced welders can create great welds with the E6013 electrode, and it works well on thin to thick metals. It also works great with A/C and D/C machines and can be used in any position, including overhead.

The E6013 electrode has a smooth weld appearance, making it a great choice for beginners. To get the most out of this electrode, make sure the joint is clean, as some minor rust is not a problem.

Proper joint preparation is key to a successful weld, so clean the joint with a wire wheel or grinder and remove any oil, moisture, paint, or other contaminants. This will make the welding process much easier.

The recommended amperage range for the E6013 electrode varies depending on the electrode size and metal thickness. To set up your welding machine, read the electrode manufacturer's recommendations or consult a welding supply store for guidance.

Here's a quick guide to setting up your welding machine:

Remember to set the welder to the middle of the recommended amperage range and adjust as needed. Practice makes perfect, so start with scrap metal and adjust the amperage until the bead looks smooth and is washed properly into the metal.

For most uses, the E6013 is a great all-around electrode choice. It's versatile and can be used to weld sheet metals, heavy plates, and everything in between.

6010 is commonly used in pipeline construction, refineries, gas plants, and utility piping along with its variants, 7010 and 8010.

Its "fast freeze" classification allows the skilled welder to fill gaps in joints, within reasonable allowances, but might prove difficult with other kinds of electrodes.

E6010 is very forgiving of joint imperfections and surface impurities.

However, 6010 welds do not have the same ductility as you might get from a 7018 electrode, so it would not be a good choice for something under cyclical stress or anywhere ductility is a consideration.

It's best to use 6010 on pipes, especially for root passes, railings, and sheet-metal applications.

Running 6010 too hot and fast can result in undercut and trapped slag inclusions.

Because of its arc characteristics, 6010 can result in more splatter, cleaning time, and higher costs.
