Stick welding—also known as Shielded Metal Arc Welding (SMAW)—is one of the most common welding processes used across many industries. A key component to this process is the welding rod, also known as the electrode. Choosing the right stick welding rod is essential for achieving quality welds, whether you’re working with steel, stainless steel, or specialty metals.
At WeldingMart.com, we offer a wide range of high-quality stick welding rods to meet various needs and applications. In this guide, we’ll cover everything you need to know about stick welding rods, including types, applications, and how to choose the right one for your project.

What Is a Stick Welding Rod?
A stick welding rod is a consumable metal rod coated in flux, which serves as the filler metal and protective shield during welding. When the arc melts the rod, it fills the joint with molten metal, while the flux coating forms a gas shield, preventing contamination from the air and leaving behind slag to protect the weld as it cools.
Types of Stick Welding Rods
The most commonly used stick welding rods are classified by the American Welding Society (AWS) standards, with each rod type denoted by a specific code. Here’s a breakdown of some popular types:
1. E6010 Welding Rod
- Features: High penetration, deep weld pool, fast freeze.
- Applications: Ideal for root passes in pipe welding and general-purpose welding.
- Strength: 60,000 psi tensile strength.
2. E6011 Welding Rod
- Features: Similar to E6010 but suitable for AC or DC polarity; good for vertical and overhead welding.
- Applications: Used in repair work, rusted or dirty metals, and outdoor jobs.
- Strength: 60,000 psi tensile strength.
3. E6013 Welding Rod
- Features: Produces a soft arc with moderate penetration; good for clean and thin materials.
- Applications: Light fabrication, thin sheet metal, hobby welding.
- Strength: 60,000 psi tensile strength.
4. E7018 Welding Rod
- Features: Low-hydrogen electrode, smooth arc, high ductility.
- Applications: Structural steel, heavy equipment repair, pressure vessels.
- Strength: 70,000 psi tensile strength.
5. E7024 Welding Rod
- Features: High deposition rate, suitable for flat and horizontal positions.
- Applications: Heavy fabrication, thick materials.
- Strength: 70,000 psi tensile strength.

How to Choose the Right Stick Welding Rod
Selecting the right welding rod is essential for ensuring quality welds. Here are some critical factors to consider:
1. Base Material
- Steel: For carbon steel, E6010, E6011, E6013, and E7018 are popular choices.
- Stainless Steel: E308L and E309L rods are best suited for stainless steel applications.
- Cast Iron: Specialty electrodes, like E312 or nickel-based rods, are required for cast iron.
2. Welding Position
- All Position: For versatile applications in flat, horizontal, vertical, and overhead positions, use E6010, E6011, or E7018.
- Flat and Horizontal Only: E7024 and E6013 rods are optimal for flat and horizontal welds.
3. Polarity and Power Source
- Direct Current (DC): E6010 and E7018 rods perform best on DC current, typically used for structural welding.
- Alternating Current (AC): E6011 and E6013 rods are ideal for AC welders, making them suitable for home use.
4. Thickness of Material
- Thin Materials: For sheet metal or light fabrication, E6013 rods are recommended due to their moderate penetration.
- Thick Materials: Use E7018 or E7024 rods, which have higher tensile strength and better penetration for thicker materials.
Stick Welding Techniques for Different Rods
Each rod type requires specific techniques to achieve optimal results:
- E6010: Known for its deep penetration, E6010 requires a whipping motion to control the weld pool and maintain arc stability.
- E6011: Similar to E6010, but easier to use on AC; ideal for situations where quick freeze is necessary.
- E7018: Requires a slight drag technique for smooth, low-spatter welds. Important to store in a dry environment due to its low-hydrogen coating.
- E6013: Easy to use for beginners; works well with a straight drag motion on thin materials.
How to Store Stick Welding Rods
Proper storage of welding rods is critical for maintaining their performance and preventing issues such as moisture absorption or cracking. Here are some tips:
- Low-Hydrogen Electrodes (e.g., E7018): Store in a rod oven to keep moisture out, as these rods are prone to hydrogen cracking.
- General-Purpose Rods (e.g., E6010, E6011): Store in a dry, climate-controlled environment to avoid rust and moisture absorption.
- Specialty Rods: Refer to the manufacturer’s guidelines for proper storage conditions.
FAQs on Stick Welding Rods
Q: What is the most versatile stick welding rod?
A: The E6011 and E7018 rods are among the most versatile, with E6011 working well on both AC and DC and E7018 offering a high-strength, low-spatter weld.
Q: Can I use E7018 on a home welder?
A: Yes, E7018 is compatible with home welders that have DC capabilities, making it a popular choice for home projects requiring a stronger weld.
Q: What rod is best for rusty or painted metal?
A: E6011 is ideal for dirty, rusty, or painted metals due to its deep penetration and ability to cut through contaminants.
