Dual Shield 111-RB is a low slag, high deposition flux cored electrode designed for joining structural components made of low carbon steel and can be used to weld over some primer compositions. The electrode is designed to be used with 100% CO2 gas shielding.

What is the difference between flux core and dual shield?

Metal Core wire is a hollow tubular wire filled with metal oxides inside requiring a shielding gas. Flux core wire (dual shield) also a hollow tubular wire but filled with fluxing agents similar to flux on smaw electrodes may require an external shielding gas plus the gas produced from the wire’s flux.

What is dual shield wire?

Dual shield welding uses both a slag system and an external shielding gas to protect the arc from the environment. The wire used in the process is often described as a “double shielded” electrode. The wire adds the desired level of alloy elements to the puddle created by the melting metal.

Do you need shielding gas with flux core wire?

Self-shielding flux-cored wire does not require external shielding gas because the weld pool is protected by gas generated when flux from the wire is burned. As a result, self-shielding flux-cored wire is more portable because it does not require an external gas tank.

What is dual shield Fcaw?

Flux cored arc welding (FCAW), also know as dual shield welding, is a semi-automatic arc welding process that is similar to metal active gas (MAG) welding. FCAW uses a continuous wire fed electrode, a constant-voltage welding power supply, and similar equipment to MAG welding.

Can you use shielding gas and flux core wire at the same time?

You can use gas with regular flux core, but it is a total waste of gas. The flux in dual shield wire doesn’t shield the weld, it causes better deposition rates and weld characteristics in the weld. Gas is needed with dual shield to shield the weld, but not with flux cored.

What gas is used for dual shield flux core?

Dual Shield 111-RB is a low slag, high deposition flux cored electrode designed for joining structural components made of low carbon steel and can be used to weld over some primer compositions. The electrode is designed to be used with 100% CO2 gas shielding.

What is flux core wire?

Self-shielded flux-cored welding is a wire welding process in which a continuous hollow wire electrode is fed through the welding gun into the weld joint. Instead, a flux compound contained within the wire reacts with the welding arc to form a gas that protects the weld pool.

Is flux core better than MIG?

However, by using flux core, you are in a better position to weld thicker metals with less amperage to that of MIG. Therefore the argument that flux core offers better metal penetration is equally valid.

What are the disadvantages of flux core welding?

The Disadvantages of FCAW

• A high level of noxious fumes which must be ventilated.
• Higher electrode wire cost compared to solid electrode wires.
• More costly equipment than many other welding processes.
• Less portable equipment than SMAW or GTAW.
• The slag covering the weld must be removed.

Is flux welding strong?

They work well outdoors and in windy conditions. With the right filler materials, these electrodes can make FCAW an “all-position” process. Typically, flux-cored wires create clean, strong welds.

Can all MIG welders use flux core wire?

Yeah, that will work fine. Flux core is sometimes used in MIG welders even when gas is available. For example, flux core will work in windy conditions that would blow away shielding gas. Also, flux core often gives somewhat better penetration than gas shielded wire.

Is flux core welding good?

Flux-core welding offers greater penetration, which is good for working with thicker joints. It also allows the welder to travel in all directions and hold the torch in a number of directions. This makes it particularly suited to general repairs, shipbuilding, and other types of manufacturing.

What is FCAW used for?

Flux-cored arc welding (FCAW) uses a continuous hollow wire electrode with a flux compound that protects the weld pool by forming a gas. FCAW is ideal for outdoor welding and for welding on dirty or contaminated materials, since it doesn’t require an external shielding gas to protect the weld from atmospheric elements.
