Get Innershield Welding

I have only welded with an Innershield® wire, which did not use any shielding gas. ... Just like covered or stick electrodes, they rely solely on their slag system and the gases produced from chemical reactions in the arc to protect the molten metal from the atmosphere (see Figure 1).

Gas-shielded flux-cored wires are used in operations such as shop fabrication, maintenance, and shipbuilding. Flux-cored wire welding is especially useful where the base material to be welded has some amount of scale, rust or other surface contaminants present.

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.

Tungsten Inert Gas (TIG) welding require pure Argon (AR) as a shielding gas to protect the weld pool from oxidation and from Nitrogen absorption. Regardless of what type of metal you are welding whether it is mild steel. stainless steel, copper or aluminum the gas you should use is Pure Argon.

MIG welding is clean and easy and can be used on thin or thick metals. Similar to MIG, flux-cored arc welding (FCAW)* is a wire-feed process but differs in that self-shielded FCAW does not require shielding gas. Instead, flux-cored wire shields the arc from contamination.

They are often described as a stick electrode turned inside out and are frequently used in place of the Shielded Metal Arc Welding (SMAW) or stick welding process. Innershield is an important process for steel fabrication in many industries, particularly when done outdoors.

Can any Mig be used for Gas AND Gasless Welding? No, a Mig Welder will be designed to either use Wire with Gas, Self Shielding (gasless) Wire, or both (Gas/No Gas). The difference lies in the Polarity of the Torch. To use Self Shielding (Gasless) wire, the Torch needs to be NEGATIVE (-).

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.
