Nine Lives tungsten dart rule is a simple game of elimination for any number of players. It does get a little long when there are a lot of players, however.

The Object: To be the first player to get "around the clock", that is to get at least one tungsten dart in each number from 1 through 20 in order.

The Scoring: Each player throws one tungsten dart at bulls-eye, closest to the bulls-eye goes first, furthest from the bulls-eye goes last. Each player gets three "lives" represented by three tally marks below their name. No, I don't know why they call the game 9 lives but you only get 3. Maybe it was invented with 3 players?

The Play: Each player takes a turn trying to hit each number from 1 through 20. The numbers must be hit in order or they do not count.

If a player misses with all three tungsten darts, one life is lost (a tally mark is erased) from that player. When all three of a players lives are lost, that player is out of the game.

The winner of the game is the first player to make it to 20 or the last player in the game to have any lives left.

Pure tungsten electrode is the earliest electrode used in arc welding technology.
TIG technology refers to the welding method under the function of protective gas-argon gas, that is to say, it is a technology that inlet the argon gas as a protective gas around the arc welding, isolate the air outside the welding areas to prevent the oxidation of welding material, which is also known as argon arc welding, can be used to weld metal hardware, stainless steel and other materials.

Arc welding refers to the process that using the heat generated by arc combustion (i.e., arc discharge) to make welding electrode (or welding wire) smelting with workpiece and condensation, then it will form the weld, and then a solid workpiece can be obtained, in industrial production, this method has the most wide application.

Pure tungsten electrode owns good conductivity, small thermal expansion coefficient, low resistance, low vapor pressure and high elastic modulus and other excellent performance.
Today, with the economic development, the world annual demand for the tungsten electrode is still in a growing trend. China's annual output of tungsten electrode has been growing steadily, accounting for about 3/4 of the world production of tungsten electrodes.

The content of tungsten in pure tungsten electrode is higher than 99.5%, and there are no other alloying elements existing. Compared to other tungsten alloy electrode, such as, tungsten copper electrode, silver tungsten electrode and tungsten nickel electrode, etc., because pure tungsten has high electronic work function, so its arc is more difficult than tungsten alloy electrode, and it is also difficult to maintain the stability of the arc beam. It’s the tip temperature of the electrode is relatively high, it will make the grain easy to grow, and the arc beam will be instable, leading to harder arcing, and shorter service life (improvement method: adding rare earth oxides). Therefore, tungsten is only used for AC welding.

Arc, as the name suggests, it is the process that the welding material (welding wires, welding rods, etc.) ignite the arc process.

Basic index of pure tungsten electrode

Electronic work function refers to the electronic break the bound of the nucleus, the minimum energy needed to escape from the surface of the material.
