Tungsten Electrode Grinding Angle

The pictures below show very distinctly different arc cones from the 3 different electrode angles ground. top is 60 deg, middle is 30, bottom is 15. practical application for different tungsten grind angles Arc starts are crisper with a very sharp tip...and there are times when a crisp sure arc start is more important than the penetration profile.

Always purchase your Pre-Ground Tungsten Electrodes from a trusted source like Arc-Zone, as manufac-turing and grinding methods can greatly affect tungsten electrode performance. Whatever your TIG/GTAW or Plasma welding application, the electrode should be properly cut and tapered. Selecting the grind Angle

20-02-2019· 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).

Pure tungsten is a very heat-resistant material with a fusion point of approximately 3,380 degrees C. By alloying tungsten with a few percent of a metal oxide, the conductivity of the electrode can be increased which has the advantage that it can thereby resist a higher current load.

17-03-2010· The influance of the electrode grind angle should be very appearent. To better understand its function, it is best to see it in application. Take a piece of 3/32 tungsten. It could be Ceria, Lanthia, or Thoria. Grind a very long taper - 20 to 30 degrees of included angle.

• Cut tungsten electrodes .040/.062 diameter with wire cutters or used their hands. • Cut tungsten electrodes 3/32 to 1/8 diameter by using 2 pairs of pliers and a twisting motion or notched the electrode on the grinding wheel and used two pairs of pliers. • Cut tungsten electrodes over 1/8 diameter using a sharp hammer blow to the,

electrodes are precision ground consistently once a welding procedure is established. Arc-Zone recom-mends using a dedicated tungsten grinder, which allows you to pre-set the angle. A tungsten grinding machine is also safer than a bench grinder and some offer dust collection.

09-12-2021· Tungsten Electrode Sharpening Using Bench / Angle Grinders A bench or angle grinder is the most common tool used to sharpen tungsten electrodes. The grinder used to sharpen tungsten should be clean, have a fine hard stone, and use it for grinding tungsten only.

Electrode included angle (taper) prep: The single most important aspect of proper electrode grinding is that the grind be done longitudinally. Tungsten electrode manufacturing is done with the molecular structure of the grain running lengthwise. Grinding crosswise is grinding against the grain. Additionally, electrons flow at a greater

A dry tungsten grinder is a portable piece of equipment that is easy to operate and helps in the repetitiveness of the sharpening. Ideally but not always, dry electrode sharpeners will feature a "closed process" that limits exposure of tungsten particulates and sharpening powder to

Use a dedicated, tungsten-only grinder or sander. Grind parallel to the length of the rod, never across it. Hold the electrode to the grinder wheel at an angle of 22.5°. Taper back about 2/3 of the rod diameter and leave a flat spot about 2/3 of the rod diameter on the tip for the best arc. Wipe it clean with acetone.

03-12-2020· Angle grinder, whetstone or abrasive mop – there are the most adventurous approaches to sharpen tungsten electrodes manually. In any case, do not try to grind the tungsten electrode freehand! For a good welding result, the tip must be concentric and the sharpening surface smooth.

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.

17-03-2010· The influance of the electrode grind angle should be very appearent. To better understand its function, it is best to see it in application. Take a piece of 3/32 tungsten. It could be Ceria, Lanthia, or Thoria. Grind a very long taper - 20 to 30 degrees of included angle.

Tungsten Grinder Tip Geometry. Electrode Tip angle varies from 15 o to 180 o. Narrow angle and Wider angle will effect on bead width, Arc starting, current carrying capacity, arc stability, weld penetration and electrode life. Sharper Electrode (Narrow angle): Wider weld bead, Easier arc striking, less amperage, improved arc stability, less,

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.

24-01-2005· I sharpen tungstens with a 35 degree included cone angle with a narrow 60 degree cone at the tip so it looks like the ogive of a long boat-tail bullet. When you get practiced you can tune up a blogged-up tungsten electrode in about 2 minutes free hand by twirling it in your fingers against an angle grinder held in your lap.

The rest of us need to use a tungsten electrode grinder to ensure welding quality. If you are a beginner at this, it is best to use the best practices when grinding your tungsten electrodes. You should use the commercially available grinders from hardware shops or online stores.

grinding machine that fulfils the requirements for safe and environmentally friendly grinding of Tungsten electrodes in high quality for TIG and plasma welding. Grinding in the longitudinal direction of the electrode, variable grinding angle, three grinding positions on the diamond disc and the electrode holder ensure efficient grinding.

When grinding on an open belt or bench grinder, the angle is not accurate, and it is difficult to achieve a uniform smooth surface on the electrode. This will cause energy loss and unstable arc behaviour, resulting in a poor welding quality and a short service life of the electrode.
