TIG Tungsten Grinding - Miller Welding Discussion Forums

Aug 10, 2018· Waste tungsten carbide can generally be reused by APT (ammonium paratungstate) process, zinc recovery process or by pulverization. These "recycled" tungsten carbide powders generally have better, predictable densification because their surface area is smaller than tungsten carbide powder made directly from the tungsten carburizing process.

How is Tungsten Carbide Formed? | Chronicle

Aug 14, 2015· Tungsten electrodes are manufactured with the molecular structure of the grain running lengthwise and thus grinding crosswise is "grinding against the grain." More importantly, electrons flow at a greater density on the surface of the electrode. If electrodes are ground or polished crosswise the electrons have to jump across the grinding marks.

Nov 27, 2012· Abrasive as all hell, generally a miserable, slow and expensive process. Due to the nature of the material it tends to be very sensitive to excessive tool pressure and likes to fracture catastrophically. As John Welden said even using solid diamond turning inserts ends up being essentially a grinding process as you just make dust.

How to Grind Tungsten Carbide | eHow

The final shaping of tungsten parts is frequently done by grinding. Silicon carbide wheels with a hardness of J to L and a grain size of 100 to 120 have proven useful for most applications. Since tungsten is hard and brittle, surface checking can be a problem unless adequate cooling is used.

Eastwood Diamond Tungsten Grinder for TIG Welder Rods

Dec 31, 2014· I use a regular bench grinder (dedicated wheel on one side) and a drill. I chuck the electrode in the drill and then apply it with rotation to the grinding wheel at a steep angle. It makes a very symmetrical cone shape. I don't use red banded electrodes (thoriated electrodes are radioactive so the grinding dust is hazardous).

tungsten grinding question/discussion

During the grinding process, particles of tungsten may be produced with thoria on the surface. It is these dust particles that create the major hazard, as they may be inhaled, and the thoria may release …

TURNING vs GRINDING of Tungsten Carbide (WC) Composite Rolls

Effects on Tungsten Grinding (Tig) - YouTube

Alternatively, you can pull the tungsten away from the grinding wheel when you need to re-grip it then push it back against the grinding wheel which also will leave a flat spot on the point. Also, and because finger rotation is a manual process the speed of rotation varies thereby causing an up and down swirling pattern on the point rather than ...
