However, note that too much EP causes the tungsten to ball excessively (Figure 2D) and provides too much etching. Lastly, when TIG welding aluminum, do not start welding until the puddle has the appearance of a shiny dot. This indicates that the oxide has been removed and it is safe to add filler and move forward. Adding filler to the weld zone before the oxide layer is adequately removed will

Tungsten Deposits in the United States

Tungsten deposits have been mined in the United States since the late 19th century, but there has been minimal production of tungsten from mines in the United States since price crashes in the 1980's. Tungsten is necessary for strategic, consumer, and commercial applications. Due to its strength, hardness, high melting and boiling points, tungsten is used in wear-resistant applications
