Flux-Cored Arc Welding
Flux-coated arc welding is one of the metal welding techniques that we offer as a company. As a reputable metal fabrication company, we offer a broad range of services to our customers in Ventura, Los Angles, San Bernardino, Riverside, and Orange County. What this implies is that we will choose the best aluminum welding process for a given application.
However, one of the frequently used and most useful welding processes is flux-cored arc welding (FCAW). This technique has some outstanding capabilities and advantages that you can take advantage of. However, like any other welding technique in the market, it also has its own limitations and disadvantages.
Therefore, the flux-cored arc welding technique is not ideal for all applications. The secret is just knowing when to apply this technique and when to go for the other welding processes. We have a professional team that will make sure that you don’t go wrong in choosing a metal welding technique.
What Is Flux-Coated Arc Welding (FCAC)
The initials FCAW basically refer to flux-coated arc welding process. It is an automatic or semi-automatic welding technique that uses a continuously-fed tubular electrode which contains a flux. It tells you why the electrode is ‘flux cored.’
The flux has powdered metals and mineral compounds that generate a protective slag across the welding bead. It in turn helps in protecting the finish and quality of the weld. That is why we have so many people in the United States who are using out FCAW welding services.
Flux-coated arc welding resembles GMAW or MIG welding and also SMAW or stick welding. However, not that FCAW utilizes a continuously fed electrode, it does not call for the use of frequent restarts.
This, in turn helps in reducing the chances of defects which produces a more uniform weld. The continuous nature of this type of welding also support higher productivity. There are basically two major types of flux-cored welding processes:
1. No Shielding Gas
The flux-cored electrode that is used in FCAW produces its own protective gas for shielding the weld. Thus, you can perform the FCAW with no extra shielding gas whatsoever without compromising the quality of the weld in any way. It eliminates the setup and cost that is associated with a distinct shielding gas system.
FCAW with no shielding gas is more effective for thin and flat-position metals. The absence of a shielding gas makes FCAW to be an effective process in windy and outdoor environments that would dissipate the shielding gas. It is one of the techniques that we use in offering aluminum welding services to our customers in the United States.
2. With Shielding Gas
The process is more appropriate for welding thick metals that are out of position especially in structural steel welding. You can use FCAW with a shielding gas for greater consistency and quality. It is often referred to as dual welding because both the flux and the shielding gas are used in shielding the gas.
The process is more ideal in controlled environments like fabrication shops where wind can’t interfere with the shielding gas. The shielding gas is typically CO2 (carbon dioxide) or a mixture of argon-carbon dioxide like C-25 that contains 25% carbon dioxide and 75% argon. It is also one of the techniques that we use in the welding process.
The Benefits of Flux-Coated Arc Welding
There are so many benefits if FCAW that make it a popular welding option. It is one of the reasons that we use this technique for metal welding. These main benefits include;
- Yields consistent and high-quality welds with very few defects.
- Ideal for both shop welding and outdoor welding.
- More forgiving on base metal contaminants like scale and rust .
- You can use it in all positions with the correct filler material.
- Allows a high productivity of welding.
- A high deposition rate that represents the speed at which the filler metal is applied.
- The weld arc has excellent visibility.
- Much easier to learn in comparison to the other metal welding processes.
- Provides and excellent welding penetration.
Limitations of Flux-Cored Arc Welding
As we said earlier, all welding techniques have their own limitations. Therefore, he FCAW process is not an exemption. However, the advantages of this process overpower its disadvantages. Some of the common limitations of this process include;
- A high volume of noxious fumes that have to be ventilated.
- Must remove the slag that covers the weld.
- Equipment is more costly than the other welding techniques.
- Not ideal for all types of metals.
- Higher cost of wire electrode in comparison to the solid electrode wired.
- Equipment is less portable than GTAW and SMAW.
- Mechanical problems can result into irregular wire feed, melted contact tips, or weld porosity.
Industrial Applications of FCAW
The flux cored arc welding process has several industrial applications. It provides great consistency and weld quality on nickel-based alloys, iron alloys, and structural steel. These are all very common applications in industrial settings.
FCAW also provides an amazing weld penetration that helps in simplifying joint design. This welding technique also provide high rates of productivity that makes it to fit perfectly for projects that need a quick turnaround or those that are under a time crunch.
Lastly, even though you need to clean all the base metals thoroughly, if there is a presence of mill scale or ruse, FCAW can overcome these contaminations better than any other welding process.
