Its alsogreat for overhead and vertical up filletwelding for ship and barge fabrication.The electrode is welder-friendly, mak-ing it easier to pass tough qualificationtests and deposit great looking beads.It does all this while delivering CharpyV-Notch properties that meet many ofthe more stringent codes and pecifications in seismic applications.

ADVANTAGE LINCOLN

User-friendly for the engineer: meetsmany of the more stringent codesand standards for Charpy V-Notchrequirements, such as those listed inFEMA 353.

User-friendly for the superintendent:higher deposition rates mean fasterbuilding erection, quicker launch ofthe barge, or more throughput in fab-rication. In short: less cost and moreprofit.

User-friendly for the welder: a moreforgiving arc with greater penetrationmakes it easier to pass qualificationtests, and makes for better qualitywelds in production and thewelds look great.

NR-233 has been formulated to minimize gas marking, even after theelectrode has been exposed to theatmosphere.

A stiffer electrode than competitivealternatives, NR-233 feeds betterwith fewer production interruptions.

STORING INNERSHIELD ELECTRODES

In general, Innershield electrodes will produce weld depositswhich achieve hydrogen levels below 16 ml per 100 gramsdeposited metal. These products, like other products whichproduce deposits low in hydrogen, must be protected fromexposure to the atmosphere in order to maintain hydrogenlevels as low as possible, preventing rusting of the productand prevent porosity during welding. Accordingly, the follow-ing storage conditions are recommended for Innershieldelectrodes in their original, unopened boxes and plastic bags.

The recommended storage conditions are such that theymaintain storage conditions above the dew point to preventmoisture contamination on product.

For best results, electrode should be consumed as soon aspracticable. Properly store electrode may be kept up to threeyears from the date of manufacture. Consult your Lincolndistributor or sales representative if there is a question as towhen the electrode was made.

Once the electrode packaging is opened, Innershield elec-trodes can be subject to contamination from atmosphericmoisture. Care has been taken in the design of theseproducts to ensure that they are essentially resistant tomoisture pick-up; however, condensation of the moisturefrom the atmosphere onto the surface of the electrode can besufficient enough to degrade the product.

The following minimum precautions should be taken tosafeguard the product after opening the original package.Electrode should be used within approximately 1 week afteropening the original package. Opened electrodes should notbe exposed to damp moisture conditions or extremes intemperature and/or humidity where surface condensation canoccur. Electrodes mounted on wire feeders should beprotected against condensation. It is recommended that

electrode removed from its original packaging be placed inpoly bags (4 mil minimum thickness) when not in use.

Innershield electrodes will evidence high moisture levels in theform of gas tracks, higher spatter and porosity. Any rusty elec-trode should be discarded.

Innershield Products Used for Applications RequiringMore Restrictive Hydrogen Control (-H Electrodes)

The AWS specifications for flux-cored electrodes, AWS A5.20and A5.29, state that Flux-cored arc welding is generallyconsidered to be a low hydrogen welding process. To furtherclarify the issue, these specifications makes available optionalsupplemental designators for maximum diffusible hydrogenlevels of 4, 8 and 16 ml per 100 grams of deposited weldmetal.

Some Innershield products have been designed andmanufactured to produce weld deposits meeting morestringent diffusible hydrogen requirements. These electrodesare usually distinguished by an H added to the productname. These electrodes will remain relatively dry underrecommended storage conditions in their original, unopenedpackage or container.

For applications in which the weld metal hydrogen must becontrolled (usually H8 or lower), or where shipping and storageconditions are not controlled or known, only hermeticallysealed packaging is recommended. Innershield electrodes areavailable in hermetically sealed packages on a special orderbasis.

Once the package has been opened, the electrode should beused as soon as practicable.
