All the welding processes are great according to their working level. However, there are 5 major types of welding, and it seems like all the welding processes are the same. but people are confused about the main difference between all of them and think about which one is better for welding purposes. Moreover, the most common welding process people use is FCAW and SMAW. You might want to know the main difference between FCAW vs SMAW.
FCAW uses a tubular electrode filled with flux that requires fewer skills, is Self-shielded or gas-shielded, high deposition rate, and deep penetration, is easier to control heat, and is expensive. On the other hand, SWAM uses a solid electrode rod that requires a higher skill, is Self-shielded, slow deposition rate, has deep penetration, has difficulty controlling heat, and is affordable. Let’s explore more about these welding processes and also what their pros and cons are.
What is Flux-Cored Arc Welding (FCAW)?
FCAW is a type of semi-automatic arc welding that is also known as dual shield welding and is similar to MAG. This welding process was developed in the 1950s as an alternative to MMA that uses a Shielded Flux Core and has some unique features and benefits.
FCAW mostly works with most carbon steels, cast iron, stainless steel, and surface alloys so, it’s working method very well. To fuse base metal at the weld-joint area, this method of welding uses the heat produced by an electric arc.
This arc develops between the metallic workpiece and the constantly fed tubular cored consumable filler wire, melting the wire and the workpiece of metal together to establish a weld connection.
The working process of the FCAW is divided into two parts that are:
- FCAW by using an external shielding gas.
- FCAW depends on the flux core to shield the weld area.
What is Shielded Metal Arc Welding (SMAW)?
SWAW is a type of oldest arc welding technique that is also known as manual metal arc (MMA or MMAW) welding and is commonly known as stick welding. This welding process was developed in 1888 by Charles L.Coffin in America.
Stick welding mostly works with carbon steel, low alloy steel, cast iron, stainless steel, and high alloy steel. This type of welding process is a commonly used arc welding process. This process is used to join metals by melting the workpiece and a consumable electrode.
Stick welding uses a flux covering to shield the molten metal joining it from the environment and oxidation. This is significant because the welding process doesn’t require any form of external shielding gas. The flux layer is inserted into the weld and then passes through the surface as slag.
What is the difference between the FCAW vs SMAW?
These welding processes are similar to each other that are used to join metal but they are different in working. Let’s describe the main difference between FCAW vs SMAW in detail.
|In FCAW the flux is present at the core of the electrode.||In SMAW the entire electrode is coated with an inert gas.|
|FCAW is used in the working process of self-shielded or gas-shielded.||SMAW is the self-shielded working process.|
|It gives the quick operation working.||It gives slow operational working.|
|FCAW welding process can weld a wide range of metals.||It can weld a limited range of metal.|
|During the welding process, it is easy to control heat.||To control the heat is difficult during the welding process.|
|The flux is filled with tubular wire.||The flux is coated with consumable electrodes.|
|It uses a filled flux tubular electrode.||It uses a solid electrode rod.|
|The rate of filler metal deposition is high.||The rate of filler metal deposition is low.|
|To weld the metal required a lower skill level.||To weld the metal required a higher skill level.|
|It uses a thin and long wire as an electrode.||This welding process uses a short and small wire as an electrode.|
|It can be programmed and reduces errors.||It works manually so the chances of error.|
|The type of electrode is tubular.||The type of electrode is cylindrical or rod.|
|It’s best for indoor use.||SMAW is best for outdoor use.|
|It’s more expensive.||It’s affordable.|
What are the Similarities between the FCAW and SMAW?
FCAW vs SMAW are two different arc welding processes but both have some similarities. Let’s discuss them below.
- FCAW and SMAW are two arc welding systems that use the electric arc to produce heat to join the metal.
- Both of them can weld a wide range of metals like stainless steel, cast iron, various alloys, and carbon steel.
- A strong and long-lasting relationship develops whenever the metals are joined heated at their intersection and fused permanently as they cool and solidify.
- The molten metal manufactured by the arc’s heat—the weld pool—is formed by both SMAW and FCAW. For the fusion of the base metals, this pool is required.
- In both welding processes, during welding, the slag-generated smoke decreases the apparent visibility of the weld zone. FCAW releases an excessive amount of smoke.
- Slag entrapment risks are common with both techniques.
What are the Pros and Cons of FCAW and SMAW?
Both are different welding processes that have advantages and also have disadvantages.
|FCAW Pros and Cons|
|FCAW is a semi-automatic process.||It’s more expensive.|
|It is easy to clean the spatter.||To weld cast iron or aluminum is not accurate.|
|The working process of welding is fast.||Flux can cause contamination with non-ferrous metal.|
|It controls the input heat easily.|
|SWAM Pros and Cons|
|The stick welding process is affordable and is not very expensive.||Completing the welding process takes more time.|
|Welding machines can be used in out-of-the-way locations because they are compact.||It’s difficult to clean the splatter with huge volumes.|
|By using stick welding you can cast iron, stainless steel, weld steel, and nickel alloys.||Arc that produces the heat that causes warping and distortion.|
|This welding system provides a high-quality weld.||The process of working is slow.|
|It produces deep penetration.||It welds the metal in a limited range.|
What are the uses of FCAW vs SMAW?
FCAW and SMAW have similarities but both of them perform different project tasks according to the requirements and needs.
|The FCAW welding process is suitable for outdoor welding.||SMAW is most suitable for repair, construction work, and maintenance for indoor tasks.|
|This welding process is most normally used for welding steel beams and steel frames.||It is normally used to perform tasks like structural steel works and shipbuilding.|

Cost comparison between FCAW and SMAW
The cost of FCAW vs SMAW depends on various factors. However, the SMAW welding process is affordable but FCAW is expensive. The cost of the SMAW and FCAW welding process depends on the three factors such as:
|Electric Power Cost||0.035||0.014|
Which one is better: FCAW vs SMAW?
It’s up to you which one is better for your projects. After a deep study of both, you can decide according to your needs. FCAW is easy to use and does not require high skills but SMAW is easy to understand but its practical use is difficult.
Both of them are used to join metal. If you are confused about choice one for your project consult with the welding professional who can give you the best guidance according to your needs.
FCAW and SMAW are two different arc welding processes that both have some similarities. In accordance with the details of their welding tasks, you identify which technique is appropriate after taking into consideration variables like the material thickness, the conditions outside, and what you want in weld quality.
The working process not only requires the cost of them but also requires great work that each welding process was established due to some reason. So, you ought to consider these aspects in order to select the most affordable and suitable welding process for every particular task while different projects might gain advantages from one method than another.
