The E6022 is a rather unique welding rod that is commonly used in the welding of roof decking for beam support. It is for this reason that it is often referred to as a decking rod. This rod has a set of characteristics that make it uniquely suited for this task.
So what is the 6022 welding rod and what application can you use it in? Let’s look at some of the notable characteristics of this rod.

The 6022 Rod Meaning
The 6022 rod is a highly fluid rod with a minimum tensile strength of 60,000 kpsi. Due to it being very fluid it can only be used in the flat or horizontal position. As for its coating, it is a high titania sodium coating and the rod can be used in both AC and DC. It is an excellent option for downhill welding to join light gauge metals.
The Characteristics Of The 6022 Rod
- As mentioned this welding rod has a minimum tensile strength of 60,000 kpsi
- The weld bead produced by this rod can be more convex and less uniform especially when welding at high speeds
- Since it is used where burn-through spot welding is required, this rod requires a high travel speed and current.
- It is known for its smooth and easy-to-control arc
- This welding rod offers good penetration with minimal spatter
- As for the slag you can expect a light slag when using this rod.
- This rod does require redrying for 30 to 60 minutes at a temperature of between 70 and 100 degrees celsius before use.
Advantages and Disadvantages of the 6022 welding Rod
As with any other welding rod, the 6022 has its pros and cons. Knowing the pros and cons of this rod will help you know if it is a fit for you. So what are its pros and cons?
Advantages Of 6022 Electrode
- One of the main advantages of this welding rod is that it offers reliable starts and re-starts, no re-work is necessary when working with this rod
- Since it has minimal spatter and a light slag there is less clean up required after welding, and it does have a nice bead
- The rods have good penetration which results in strong and reliable welds
- It can be used with Direct Current Electrode positive (DCEP), Alternating Current, or Direct Current Electrode Negative (DCEN).
- Can be used on rusted or hard to clean surfaces such as greasy or painted steel
- Due to its being very fluid it cannot be used in the vertical down and overhead position and only works best in the flat, horizontal, or vertical up positions.
- It does require special care when storing and requires redrying at temperatures of 70 to 100 degrees Celsius before use.
- At high speeds, it can result in an overly convex and uniform weld bead
The 6022 Welding Rod Polarity and Amperage Setting
|Deposition Efficiency (%)
|DCEP, AC , DCEN
|DCEP, AC ,DCEN
When it comes to polarity the 6022 can work with DCEN, DCEP, and AC. As for the amperage it depends on the size of the rod. The amperage setting for this rod can range between 60 to 200 amps.
For thinner rods of 3/32 inches in diameter, an amperage setting of between 60 and 100 amps is recommended. For thicker rods though from ⅛ inches all the way to 5/32 inches a higher amperage of between 80 to 200 amps is recommended.
Charpy V-Notch Impact (toughness) Requirements for E6022 type electrode
For the 6022 welding rod toughness requirements, weld metals need to have a tensile strength of more than 67,000 psi. There is no requirement for yield strength for this rod. The same goes for the Charpy V-notch requirements, there are none for this electrode.
Chemical And Mechanical Properties
This rod has a minimum tensile strength of 60,000 psi. As for its yield strength, it is between 56,000 and 64,000. The elongation stand at 24 to 26 % in 2 inches. What about the chemical composition of the rod?
This rod contains several chemical elements from carbon to sulfur. The actual content is 0.14 carbon, 1.20 manganese, 0.28 silicon, 0.025 phosphorous, and 0.0012 sulfur. In addition to these chemical elements, the rod also contains 0.02 Nickel, 0.03 Chromium, 0.04 molybdenum, and 0.01 vanadium.
Preferable Welding Techniques
|Short arc or drag technique
|angle electrodes 10-15° from 90°,
|angle electrodes 10-15° from 90°, dragging technique
Differences Between The 6022 and 6010 Welding Rods
One of the most commonly used electrodes is the 6010. However, this electrode is very different from the 6022 and there are only minimal similarities between the two. The first similarity is that both can be used on dirty or rusted surfaces.
Also, both have a minimum tensile strength of 60,000. When it comes to the differences, the 6022 is a very fluid rod while the 6010 is a fast-freezing rod thanks to its cellulose flux. Additionally, the 6010 is a DC-only all positions rod.
The 6022 on the other hand cannot be used in all positions and works with both DC and AC. And while the 6022 requires high travel speed, the 6010 works well with a whip and pause technique.
Finally, the 6022 has a relatively easy to control arc compared to the 6010. Furthermore, the 6010 is best suited for stove pipe welding, while the 6022 is suited for welding roof decking for beam support.
Is the 6022 used in other applications other than decking?
The 6022 welding rod is excellent at plug welds as well as tack welding rusted, galvanized, or dirty steels. This is why it is mainly used for decking. Other than this though, the rod has a high burn through, which makes it unideal for critical applications.
In our view, you can use this rod for other non-critical applications other than decking. It will be a nice option for tacking welding dirty or rusted junk metals. Other than this the probability of it burning through metal in more critical applications is too high to make it a viable option.
How to Weld With 6022
When working with the 6022 you need to set the amperage high. For this demonstration, we will be using a 5/32 inch rod in the flat position. To start with set the amperage to between 150 and 190 amps.
Because of the high amperage, a single pass is all that is needed to weld. Use a fast travel speed with the rod. The rod works well for spot welding two sheets of metal together due to its high fluidity.
The 6022 is not the most common rod due to its limited usability. However, for tack welding and spot welding steel sheets together, this is one of the best rods. It will burn through any type of surface regardless of dirt or rust.
