10. TUNGSTEN OPTIONS AND ALTERNATIVES

TRI-MIX™TUNGSTEN ELECTRODE

• Three oxides scientifically balance the migration and evaporation rates to extend the service life

• Increased number of arc starts before re-sharpening and fewer misfires saves money and time

• Lower work function requires less energy to start than 2% Thoriated tungsten and runs cooler

• TRI MIX ™ is a non-radioactive tungsten

• FREE Samples available upon request

• FREE Tungsten Guidebook to clarify electrode selection and preparation.

CRYO-T ™TUNGSTEN ELECTRODE

• Cryogenically treated Thoriated Tungsten produces a more dense structure of the Thoriated and tungsten blend.

• Easiest starting Tungsten.

• Much longer tip life compared to non-treated 2% Thoriated Tungsten electrodes.

• More consistent welds as a result of crisp starts and longer electrode life.

THORIATED TUNGSTEN RADIOACTIVITY INFORMATION

Thorium is a radioactive element or additive used in tungsten welding electrodes to assist in arc starting.

Although companies involved in welding have been using Thoriated electrodes for many years, the industry

is becoming more mindful of their potential health hazards. The following are notes, warnings, and

recommendations from various organizations on the use of Thoriated tungsten welding electrodes.

American Welding Society: "Thorium is radioactive and may present hazards by external and internal

exposure. If alternatives are technically feasible they should be used..." If welding is to be performed

in confirmed spaces for prolonged periods of time or if electrode grinding dust might be ingested, special

precautions relative to ventilation should be considered. The user should consult appropriate safety personnel."

Standard Manufacture's Warning: "Thorium dioxide is a naturally occurring radioactive element. It is an alpha

emitter and, as such, its primary hazard lies in Inhalation of dust/fume." "Thorium dioxide has been identified as

a carcinogen by the NTP and IARC." (These quotes are from Osram Sylvania MSDS sheets).

The Welding Institute: Thorium is a radioactive element. The HSE has recommended to factory inspectors that,

where Thoriated tungsten electrodes are not necessary, users should be encouraged to look for alternatives.

Cancer Assessment: Thorium dioxide has been identified as a carcinogen by the National Toxicology Program

and International Agency of Research on Cancer.

DIAMOND GROUND PRODUCTS OFFERS ALTERNATIVES

DGP offers Non-Radioactive High Performance TRI MIX™, 2% Lanthanated, Cryo-T and 2% Ceriated

tungsten which is in stock, ready to be shipped, and affordably priced. In most welding applications, these

types of tungsten outperforms Thorium with longer tungsten life, better arc starting, and, in some cases, higher

amperage capacity. Call us for more information and to get a FREE sample today!
