Tungsten

Tungsten, or wolfram, is a chemical element with the symbol W and atomic number 74. Tungsten is a rare metal found naturally on Earth almost exclusively as compounds with other elements. It was identified as a new element in 1781 and first isolated as a metal in 1783. Its important ores include scheelite and wolframite, the latter lending the element its alternate name.

Guidelines for tungsten electrodes

Mar 07, 2021Choosing one of the six commonly available tungsten electrodes is a crucial first step in successful gas tungsten arc welding (GTAW). In addition, tip preparation is critical. The electrode choices are pure tungsten, 2 percent thoriated, 2 percent ceriated, 1.5 percent lanthanated, zirconiated, and rare earth. The end preparations are balled, pointed, and truncated.

Green vs Purple Tungsten

Aug 30, 2021Aug 30, 2021Green vs Purple Tungsten. 08-30-2021, 11:50 AM. I have recently learned that using green tungsten in an inverter machine is a no-no. I have been welding for over 15 years and I have never heard this until now when I purchased a Dynasty 700 machine. I have used the purple for a while and I am not very fond of it so far.
