If you’re a welder, then you’re probably familiar with the different welding processes that are available for you. But if you’re new to the welding world, or just want to learn more about flux core welding, then this post is for you!
Many welders have probably heard about flux core welding but might not know what it is.
Flux core welding is a type of arc welding that uses a wire electrode that has flux surrounding the metal core. Let’s take a closer look at how flux core welding works!
In today’s blog post, we’ll discuss what flux core welding is, and how it works. So if you’re curious about this process, keep reading!
What flux core welding is?
Flux core welding, also known as flux cored arc welding or FCAW, is a semi-automatic or automatic arc welding process in which a continuous wire electrode is fed through a welding gun and into the weld pool for joining the two base materials together.
The wire electrode is consumable, meaning it melts away as the weld is formed. This process is commonly used in heavy industries such as shipbuilding and construction where it is important to create strong, durable welds.
Flux cored arc welding ( Pros & Cons)
The advantages of flux cored arc welding are:
- Faster welding speeds
- Easier to automate
- Welds can be made with minimal operator supervision
- Possible to weld in all positions
- Can be used with a variety of metals
The disadvantages of flux cored arc welding are:
- More expensive than other welding processes
- May produce more fumes and smoke than other processes
- Require more operator training than other processes
- It May be difficult to achieve consistent weld quality
Flux cored arc welding has many advantages over other welding processes, but also a few disadvantages. It is important to weigh up the pros and cons of each process before making a decision about which one to use.
Types of Flux Core Welding
There are two types of flux core welding: self-shielded and gas-shielded.
1) Self Shielded Flux Core Welding
In self-shielded flux core welding, the wire electrode contains all of the necessary shieldings, so no external gas is required.
This makes self-shielded flux core welding a good choice for outdoor applications or for welding metals that are difficult to shield with an external gas.
2) Gas Shielded Flux Core Welding
Gas-shielded flux core welding requires the use of external shielding gas, such as argon or CO2, to protect the weld pool from contaminants.
This type of flux core welding is often used for thin metal sheets or for delicate welds that require a high degree of precision.
Applications Of flux core welding
There are many applications where flux core welding is used some of the following are:
- Automotive- racing cars, roll cages, classic car restorations.
- Motorcycle- frames, exhaust systems.
- Aerospace- aircraft parts and repairs.
- Construction- steel buildings, bridges, scaffolding.
- Art and architecture- sculptures, metalwork for home or office.
- Thick plate fabrication
- Heavy equipment manufacturing
What metals can you weld with flux core?
There are a variety of metals that can be welded using flux core welding, including aluminum, stainless steel, and mild steel. Each metal has its specific welding requirements, so it’s important to consult a welding guide or professional welder before beginning a project.
It is important to choose the right wire electrode and shielding gas for the metal being welded, as well as the right welding parameters, to create a strong, high-quality weld.
Types of welders that use flux core welding
There are two types of welders that use flux core welding: the MIG welder and the TIG welder.
1) MIG welder
The MIG welder is a type of welding machine that uses an electrode wire that is fed through a welding torch. This electrode wire is made of metal, and it is consumable. The end of the electrode wire melts and becomes the filler material that joins two pieces of metal together.
2) TIG welder
The TIG welder is a type of welding machine that uses an electrode that is not consumable. This electrode is usually made of tungsten, and it does not melt. The heat from the welding torch melts the metal that you are trying to join together, and the tungsten electrode provides the filler material.
Both MIG and TIG welders can use flux core welding, but they each have their own advantages and disadvantages. MIG welders are generally easier to use than TIG welders and they can be used on a variety of different metals.
However, TIG welders produce cleaner welds and are better suited for joining thin pieces of metal together.
what is flux core welding used for?
The flux helps to shield the weld from atmospheric contamination, which can help to improve the quality of the weld.
This type of welding is often used in construction and other outdoor applications where windy conditions make it difficult to use a conventional shielding gas.
The flux around the electrode creates a slag that protects the weld pool from contaminants in the air. As the electrode is consumed, more flux is released to maintain this protective barrier.
Flux core welding can be done with either AC or DC power sources, although DC is generally preferred. It can also be done with self-shielded or gas-shielded electrodes.
Gas-shielded electrodes provide better protection for the weld pool and result in cleaner welds, but they are more expensive and require extra equipment.
Self-shielded electrodes are easier to use and do not require any extra equipment, but the resulting welds may be less clean and may be more susceptible to contamination.
Advantages of Using Flux Core Welding
Flux core welding has several advantages over other welding processes. Here are just a few of the benefits:
1) Faster welding speed
Flux core welding is a fast process, which means you can get your project done more quickly. This is especially beneficial if you’re working on a large project or multiple projects.
2) Easier to learn
Since flux core welding is relatively easy to learn, it’s a great choice for beginners. If you’re new to welding, this process can help you get started and give you the confidence you need to tackle more complex projects.
3) Less equipment needed
Another advantage of flux core welding is that you don’t need as much equipment as other welding processes. This makes it a more affordable option, and it’s also easier to set up and take down.
4) Great for outdoor projects
Flux core welding is also ideal for outdoor projects. Since there’s no shielding gas required, you don’t have to worry about windy conditions affecting your weld.

How to Start Flux core welding process?
- To begin flux core welding, the welder will need to set up their equipment. This includes an arc welder, a power source, and a wire feeder. The welder will also need to select the right size and type of wire for their project.
- Once the equipment is set up, the welder will need to do their protective equipment (PPE), including a welding helmet, gloves, and long sleeves.
- The next step is to prepare the work area by cleaning the metal surfaces that will be welded. It’s important to remove all rust, paint, or debris from the surface, as this can cause problems with the weld.
- Once the area is prepared, the welder will need to set their power source to the correct settings. The welder will then hold the electrode in one hand and feed it into the welding machine. As the electrode touches the metal, an arc will form, and welding can begin!

Flux core welding is generally considered to be easier to learn than MIG welding, so it’s a great choice for those who are just getting started with welding.
Is flux core welding as strong as MIG?
There is no definitive answer to this question as it depends on many factors, such as the type of metal being welded, the thickness of the metal, the welding technique used, etc.
However, in general, flux core welding is not as strong as MIG welding. This is because MIG welding uses a continuous wire feed, which provides a more consistent weld whereas flux core welding uses an intermittent wire feed. This can lead to inconsistent welds and weaker joints.
What gas do you use for the flux core?
There are many types of gas that can be used for flux core welding, but the most common and recommended type is 75% Argon and 25% CO2. This gas mix provides excellent arc stability and penetration, making it ideal for welding thicker materials.
Other gas mixtures that can be used for flux core welding include 100% Argon, 100% CO2, and a mix of 90% Argon and 10% CO2.
If you’re welding thin materials, using a gas mixture with a higher percentage of CO2 will help to increase penetration. For thicker materials, using a gas mixture with a higher percentage of Argon will help to improve weld bead appearance and increase weld strength.
When should I use flux core?
Flux core is typically used for welding thicker materials (3/16″ or greater) as it provides more penetration. It’s also commonly used for welding outdoors or in other situations where shielding gas can be difficult to maintain.
That said, many welders find that they can get good results with flux core by using a smaller electrode (1/16″ or smaller) and moving more slowly. This allows for better control of the weld pool and can help to avoid problems like porosity.
Can flux core weld through rust?
Flux core welding can be used to weld through rust, but it is not the ideal method for doing so. The flux in the welding wire will react with the rust and can cause problems with the weld.
It is better to remove the rust before welding or use another welding method.
Flux-core welding is a process that uses a continuous wire feed of both the electrode and the flux. This type of welding is perfect for projects that require a lot of mobility as it does not require an external power supply like MIG or TIG welding.
At its most basic level, flux core welding is a type of arc welding that uses a continuously fed consumable wire electrode. The electrode is covered with a flux material which helps to protect the weld puddle from atmospheric contamination and to provide a shielding gas for the arc.
Flux-core welding can be used on a variety of different types of metals, making it versatile for many applications. If you’re looking for an easy to use, portable welding option, flux-core may be the right choice for you.
