“Gas Tungsten Arc Welding” - GTAW - fre-quently called “Tungsten Inert Gas Welding” -TIG - is used to weld any commercial metal,but most frequently is employed in joiningaluminum alloys, copper, magnesium, stain-less steel and titanium.
Tungsten welding electrodes which are usedin combination with an inert gas, usually argonor helium, in a welding process which preventscontamination from oxygen and nitrogen, thusproviding a strong, ductile, homogeneousweld.
The tungsten welding electrode itself is non-consumable and is used merely as the termi-nal of the electric arc which produces the de-sired heat necessary to accomplish the join-ing of the metal. Filler metal may sometimesbe required depending on base metal thick-ness, joint design and weld characteristicswhich are desired.
Plansee Electrodes are of the highest qualityand exceed AWS Standard A5.12-80 (FormerASTM Standard B297-.65T). Plansee is Eu-rope's largest producer of TIG welding elec-trodes.
Ceriated Tungsten (Non-Radioactive)• Good arc striking • Excellent arc stability • Low electrode consumption • Ceriated tungsteneliminates the problem of disposal of grinding dust and end pieces of thoriated electrodes.Ceriated electrodes can be used in a wide range of applications and are ideally suited to thewelding of stainless and hot working steels, aluminum, nickel and nickel based alloys (superalloys), copper, refractory metals, titanium & titanium alloys and magnesium. Companies inboth manual and automatic welding can now profit from the benefits outlined above. Take ad-vantage of the new development.
Lanthanated Tungsten (Non-Radioactive)• A new development in tungsten • Best results in electrode life, starting, amperage range, upto 10 times longer life, does not splinter or split. Stays clean longer. Holds its point much longer.More actual welding time. No more stocking of different electrode types (pure, thoriated,zirconiated, ceriated). Lanthanated tungsten does it all.
Pure Tungsten and 2% Thoriated Tungsten Electrodes are still available

ELIMINATE RADIOACTIVE TUNGSTENS FROM THE WORK PLACEThe American Welding Society (A.W.S.) May-1994 Commission VIII issued a state-ment on health aspects in the use of Thoriated Tungsten Electrodes. Thorium is alow-level radioactive material that the A.W.S. determined could present a long-termhealth hazard if ingested or inhaled in sufficient quantities. During the grinding ofelectrode tips there is generation of radioactive dust, with the risk of internal expo-sure.A.W.S. Recommendation: substitution of other emitters such as cerium andlanthanium to replace thorium should be considered.
In response to this commission, our factory developed electrodes with newadditives: we first tried Cerium, respectively Cerium Oxide (known as Ceriated Tung-sten). We were able to avoid radioactivity and we also noticed much better perform-ance. After further research and development with tests on other Rare Earth Oxides,like Yttrium and Lanthanum Oxide, Lanthanum produced the best results in elec-trode life, starting, amperage range, etc. Less resistance and better oxide distribu-tion in our Electrodes provide the basis for best performance. Many reputable com-panies have evaluated Lanthanated and found major improvements in performance,elimination of health and safety hazards, and because of longer life, they found themto be much more economical.
Thoriated Tungsten Radioactivity InformationThorium is a radioactive alloy used in tungsten welding electrodes to assist in arc starting.Although companies involved in welding have been using thoriated electrodes for manyyears, the industry is becoming more mindful of their potential health hazards. The follow-ing are notes, warnings, and recommendations from various organizations on the use ofthoriated tungsten welding electrodes.
Standard Manufacturer's Warning: Thorium oxide is a naturallyoccurring radioactive element. It is an alpha emitter and as such, itsprimary hazard lies in inhalation of dust/fumes.
American Welding Society: Thoria is a very low level radioactivematerial. For the amount of thoria present in these electrodes, thelevel of radiation has not been found to represent a health hazard.However, if welding is to be performed in confined spaces for pro-longed periods of time or if electrode grinding dust might be in-gested, special precautions relative to ventilation should be consid-ered. The user should consult appropriate safety personnel.
The Welding Institute: Thorium is a radioactive element. The HSEhas recommended to factory inspectors that, where thoriated tung-sten electrodes are not necessary, users should be encouraged tolook for alternatives.
N.T.P. and I.A.R.C. Assessment: Thorium dioxide has been identi-fied as a carcinogen by the National Toxicology Program and Inter-national Agency for Research on Cancer.

Tungsten Selection ChartFinishThe electrodes are free of surface impurities,undesirable films, foreign inclusions, pipes,seams or slivers in order to assure correct op-eration of welding equipment with no adverseproperties in weld deposits.
All electrodes are produced to rigid standards
of straightness so they may be adjusted freelyin use; each electrode is colour coded accord-ing to AWS specifications.
Ground finish designates that a tungsten elec-trode has been cleaned of impurities after it hasbeen centerless ground to a uniform size.
