About The Lincoln

Electric Company

Innershield wire by Lincoln Electric is one of the most user-friendly,

convenient, versatile wires on earth. This exceptionally feedable

and consistent wire includes shielding, slagging and deoxidizing

materials built right in to its inner core. That means no external gas

bottles or flux on the job! It’s a superb choice for bridges, offshore

drilling rigs, and other outside welding applications where winds are

a factor.

Versatility. No matter what welding positions your job requires, there’s

an Innershield wire specifically designed to handle it. We’ve provided

individual wire descriptions in this brochure that will make it easy for

you to choose the right Innershield product for your needs.

Better portability. Because Innershield is completely self-contained –

with shielding, slagging and deoxidizing materials built right in to the

wire’s core – there’s no need for flux feeding systems or gas bottles.

That means increased portability of your rigs, and more efficient weld-

ing operations.

Better feedability. We’ve coated Innershield wire with specially

designed lubricants that keep the wire feeding beautifully – inch after

inch, coil after coil.

WELDING POSITIONS

The opacity of NR-203M slag to x-ray is such that slag inclusions will normally appear lighter than the weld.

Voids will normally appear darker than the weld. When using gamma-radiography, slag inclusions and voids will

normally appear darker than the weld. Improved x-ray film readability usually can be obtained by slight over-

exposure at an excitation potential consistent with good x-ray practice, but not over 240 KV. For detailed

information on welding techniques, procedure adjustments, and their effects on weld appearance and quality,

(1) The strength and elongation properties reported were obtained from a .505” tensile specimen artificially aged

at 220°F (104°C) for 48 hours, as permitted by AWS A5.20-95. A naturally aged tensile specimen may take

months to achieve the specified properties. See AWS A5.20-95, paragraph A8.3. The time required for the

natural aging of weld deposits is dependent upon ambient conditions, weldment geometry, the metallurgical

structure of the weld deposit and other factors.

Customer Assistance Policy

The business of The Lincoln Electric Company is manufacturing and selling high quality welding equipment, consumables, and cut-

ting equipment. Our challenge is to meet the needs of our customers and to exceed their expectations. On occasion, purchasers

may ask Lincoln Electric for advice or information about their use of our products. We respond to our customers based on the best

information in our possession at that time. Lincoln Electric is not in a position to warrant or guarantee such advice, and assumes no

liability, with respect to such information or advice. We expressly disclaim any warranty of any kind, including any warranty of fitness

for any customer’s particular purpose, with respect to such information or advice. As a matter of practical consideration, we also

cannot assume any responsibility for updating or correcting any such information or advice once it has been given, nor does the

provision of information or advice create, expand or alter any warranty with respect to the sale of our products.

Lincoln Electric is a responsive manufacturer, but the selection and use of specific products sold by Lincoln Electric is solely within

the control of, and remains the sole responsibility of the customer. Many variables beyond the control of Lincoln Electric affect the

results obtained in applying this type of fabrication methods and service requirements.

STORING INNERSHIELD ELECTRODES

In general, Innershield electrodes will produce weld deposits

which achieve hydrogen levels below 16 ml per 100 grams

deposited metal. These products, like other products which

produce deposits low in hydrogen, must be protected from

exposure to the atmosphere in order to maintain hydrogen

levels as low as possible, preventing rusting of the product

and prevent porosity during welding. Accordingly, the follow-

ing storage conditions are recommended for Innershield

lectrodes in their original, unopened boxes and plastic bags.

The recommended storage conditions are such that they

maintain condition of 90 grains of moisture per pound of

dry air. Examples of storage conditions that will meet this

requirement are given below:

For best results, electrode should be consumed as soon as

practicable. However, it may be stored up to three years from

the date of manufacture. Consult your Lincoln distributor or

sales representative if there is a question as to when the

electrode was made.

Once the electrode packaging is opened, Innershield elec-

trodes can be subject to contamination from atmospheric

moisture. Care has been taken in the design of these prod-

ucts to select core ingredients that are essentially resistant to

moisture pick-up; however, condensation of the moisture

from the atmosphere onto the surface of the electrode can be

sufficient enough to degrade the product.

The following minimum precautions should be taken to safe-

guard product after opening the original package. Electrode

should be used within approximately 1 week after opening the

original package. Opened electrode should not be exposed to

damp, moist conditions or extremes in temperature and/or

humidity where surface condensation can occur. Electrodes

mounted on wire feeders should be protected against con-

densation. It is recommended that electrode removed from its

original packaging be placed in poly bags (4 mil minimum

thickness) when not in use.

Ambient Maximum

Fahrenheit Celsius Humidity

60° - 70° (16° - 21°) 80%

80° - 90° (27° - 32°) 45%

90° - 100° (32° - 38°) 30%

Innershield electrodes will evidence high moisture levels in the

form of gas tracks, higher spatter and porosity. Any rusty elec-

trode should be discarded.

Innershield Products Used for Applications Requiring

More Restrictive Hydrogen Control

The AWS specifications for flux-cored electrodes, ANSI/AWS

A5.20, states that “Flux-cored arc welding is generally

considered to be a low hydrogen welding process”. To further

clarify the issue, this specification makes available optional

supplemental designators for maximum diffusible hydrogen

levels of 4, 8 and 16 ml per 100 grams of deposited weld

metal.

Some Innershield products have been designed and manufac-

tured to produce weld deposits meeting more stringent dif-

fusible hydrogen requirements. These electrodes are usually

distinguished by an “H” added to the product name. These

electrodes will remain relatively dry under recommended

storage conditions in their original, unopened package or

container.

For critical applications in which the weld metal hydrogen

must be controlled (usually H8 or lower), or where shipping

and storage conditions are not controlled or known, only

hermetically sealed packaging is recommended. Innershield

electrodes are available in hermetically sealed packages on a

Special Order basis.

Once the package has been opened, the electrode should not

be exposed to conditions exceeding 80% relative humidity for

a period greater than 16 hours, or any less humid condition for

greater than 24 hours. Conditions that exceed 80% RH will

decrease the maximum 16 hour exposure period.

After exposure, hydrogen levels can be reduced by condition-

ing the electrode. Electrode may be conditioned at a tempera-

ture of 230ºF (110°C) ± 25ºF (-3.8°C) for a period of 6 to 12

hours, cooled and then stored in sealed poly bags (4 mil mini-

mum thickness) or equivalent. Electrode on plastic spools

should not be heated at temperatures in excess of 150ºF.

Electrode that is rusty should be discarded.
