More importantly, electrons flow at a greater density on the ...
The risk of tungsten inclusions that a sharp tungsten grind angle brings can be mitigated by quality grinding. A high-quality tungsten electrode ground using computer numerically controlled (CNC) machining will have a smoother tip, with few, if any, burrs.
Grinding electrode tips crosswise has a negative effect on the stability and formation of the arc at the electrode tip. Tungsten electrodes are manufactured with the molecular structure of the grain running lengthwise and thus grinding crosswise is grinding against the grain.
Tungsten electrodes are available in different diameters from 0.5 to 8 mm for TIG welding. The most frequently used dimensions for TIG welding electrodes are 1.6 2.4 3.2 and 4 mm. The diameter of the electrode is chosen on basis of the current intensity, which type of electrode is preferred, and whether it is alternating or direct current.
Jan 15, 2008 The tungsten electrode becomes overheated and wears out more quickly. With longitudinal grinding with the grain, the electrons are led steadily to the extreme tip of the tungsten electrode. The arc starts straight and remains narrow, concentrated, and stable. A diamond grinding wheel should not be used for grinding anything other than tungsten.

Grind lines should be straight, running through the grind to the tip. And the poster above is very correct about grinding so that the sparks fly off the tip instead off back towards you. If you grind so that the sparks are going back towards your tungsten then you are contaminating it. Ive been welding for 20 years, most of that TIG welding.
Tungsten carbide saw tips are not solid tungsten carbide. They are made of grains of tungsten and carbon held together in a matrix of metal such as cobalt or nickel. There are many different grades of Tungsten Carbide. Refer to our Carbide and Advanced Material Section for more articles on Carbide.
Tungsten grinder Methods and tools for the job Unorthodox ways of tapering your electrode. If you have no other tools, you can actually use a cutting torch to sharpen your electrode. To do it, you need to get the electrode red hot using the torch. After that, you can squeeze the lever and move the flame up and down the tip of the electrode.
All holes are stationary, so we can set an offset compensation for each size hole to make sure all tungstens tip center is on the grinding center point, this offset can ensure that the lines on the tip of the tungsten electrode are as straight as possible. If the hole position is variable, offset compensation cannot be set.
During the welding operation, the accurately ground tip of a tungsten electrode is at a temperature probably in excess of 3000 C (5500 F), and without a correct and consistent diameter flat at the tip of the tungsten electrode the following problems can occur Pointed electrode tip drops into weld pool creating weld defect and X-ray defect.
Dec 03, 2020 If, on the other hand, the tungsten electrode is blunt-pointed and you weld with it at the same welding current as with the sharpened electrode, the penetration is wider and less focused. We recommend a grinding angle of 60 for TIG welding electrodes in order to achieve the best welding results. 5.
Feb 20, 2019 Grinding the top angle. Grinding a top angle on the tungsten electrode is a precision job. The angle can vary from 20 to 90 degrees. The grinding grooves should run in the longitudinal (axial) direction of the tungsten electrode and never around the tungsten electrode (radial). A tungsten electrode with the grinding grooves around the tip will hardly ever have a
