3. When flux-cored wire is welded, the dry elongation should be 15 ~ 25 mm.

4. Welding wire warehouse humidity should be maintained no more than 60%.

5. Non-vacuum packaging wire storage time should not exceed half a year, vacuum packaging wire storage time should not exceed one year.

E71T-1C and E71T-1M,Shielding gas designator.2 Indicates the type of shielding gas used for classification. The letter“C” indicates that the electrode is classified using 100% CO2 shielding gas. The letter “M” indicates that the electrode is classified using 75–80% Argon/balance CO2 shielding gas. When no designator appears in this position, it indicates that the electrode being classified is self-shielded and that no external shielding gas was used.

Frequently Asked Questions About Flux Cored Welding Wire

What is flux cored welding wire?

Flux cored welding wire is a type of welding consumable used in flux cored arc welding (FCAW), a semi-automatic or automatic arc welding process.
It consists of a tubular wire filled with flux materials that provide shielding gas, slag formation, and alloying elements during welding.
This wire is popular in industries like construction, shipbuilding, and heavy equipment manufacturing due to its versatility and efficiency.

How does it differ from solid welding wire?

Unlike solid welding wire, which requires an external shielding gas in processes like MIG welding, flux cored wire contains flux within its core.
This flux produces a protective gas shield and slag when heated, eliminating the need for external gas in many cases.
Flux cored welding is ideal for outdoor applications, as it performs well in windy conditions where gas shielding might be disrupted.

What are the advantages of using flux cored welding wire?

Flux cored welding wire offers several benefits, making it a preferred choice for many welders.
It provides high deposition rates, allowing for faster welding and increased productivity.
Its ability to weld thicker materials and perform in outdoor environments enhances its versatility.
Additionally, FCAW requires less operator skill compared to other processes, making it accessible for various skill levels.

Are there any limitations to flux cored welding?

While flux cored welding wire is highly effective, it has some drawbacks.
The process generates slag, which must be removed after welding, increasing cleanup time.
equipment and wire can be more expensive than MIG welding setups.
flux cored welding may produce more spatter, requiring additional post-weld cleanup.

What types of flux cored welding wires are available?

Flux cored welding wires are categorized into two main types: gas-shielded and self-shielded.
Gas-shielded flux cored wires require an external shielding gas, typically CO2 or a CO2-argon mix, and are suited for clean, indoor applications.
Self-shielded wires rely solely on their internal flux for shielding, making them ideal for outdoor or windy conditions.
wires also vary by alloy composition, such as mild steel, stainless steel, or low-alloy steel, to suit different welding tasks.

How do I choose the right flux cored wire?

Selecting the appropriate flux cored wire depends on the base metal, welding position, and environmental conditions.
For outdoor projects, self-shielded wires are preferable, while gas-shielded wires are better for controlled indoor settings.
Consider the mechanical properties of the weld, such as tensile strength and corrosion resistance, and consult the wire’s specification sheet for compatibility.
Always consult with a welding supplier for project-specific recommendations.

How should flux cored welding wire be stored?

Proper storage of flux cored welding wire is critical to maintaining its quality and performance.
Store the wire in a dry, clean, dry environment to prevent moisture absorption, which can lead to porosity in welds.
Use airtight containers or climate-controlled storage units with low humidity.
Avoid exposing the wire to temperature extremes, as this may degrade the flux core and affect welding results.

What happens if the wire gets contaminated?

Contaminated flux cored wire, often due to moisture or oil exposure, can cause weld imperfections like porosity or cracking.
such cases, the wire may need to be discarded or reconditioned, depending on the manufacturer’s guidelines.
Always inspect wire before use and ensure proper storage practices to minimize contamination risks.

Can flux cored welding wire be used with any welding machine?

Flux cored welding requires a welding machine capable of handling FCAW processes, typically a constant voltage (CV) power source.
Most modern welding machines can be adapted for flux cored welding by adjusting polarity (usually DCEN for self-shielded wires, DCEP for gas-shielded wires) and installing a suitable wire feeder.
Check your machine’s specifications to ensure compatibility with the wire diameter and type.
