One of tungsten's most impressive and useful properties is its high melting point, the highest of all metallic elements. Pure tungsten melts at a whopping 6,192 degrees F (3,422 degrees C) and won't boil until temperatures reach 10,030 F (5,555 C), which is the same temperature as the photosphere of the sun.
What tungsten is used for aluminum?
For these reasons, pure tungsten or zirconiated tungsten are recommended for aluminum welding. In addition, the electrode diameter for AC welding has to be significantly larger than when using DC. It is recommended to start with an electrode that is 1/8" and adjust as needed.
What is gold tip tungsten used for?
Gold Tip Tig Electrodes are suitable for both AC and DC Tig Welding applications. When used with a Direct Current (DC) output, the Tungsten Electrode can be ground to a point, which it holds well. This would be for Tig Welding Mild Steel, Stainless Steel, Tool Steels etc.

How do you shape tungsten?
Machining and Grinding: Tungsten can be machined by turning, milling, or drilling. For thick-walled parts, slight preheating of the work to 400 oF is sometimes helpful, otherwise a highly chlorinated oil such as trichloroethylene is used. The final shaping of tungsten parts is frequently done by grinding.
What do you grind tungsten with?
To grind the tungsten properly and to prevent contamination, it is preferable to use a grinding wheel especially designed for tungsten grinding, resistant to tungsten´s hardness. Grind the electrode straight on the direction of the wheel at a 90° angle and make sure that the grind marks are lengthwise.

Do you need to sharpen tungsten?
2. Never sharpen the TIG welding electrode freehand. For a good welding result, the tip must be concentric and the sharpening surface smooth. Even with very steady hand control, you would never get a perfect tungsten electrode cut.Dec 3, 2020
