Why would I use Ceriated or Thoriated tungsten instead of Pure?

With the introduction of new power source technologies, the use of pure tungsten is decreasing.
Pure tungsten melts at a lower temperature causing it to easily form a rounded ball at the tip. When the ball grows too large, it interferes with your ability to see the weld puddle and causes the arc to become unstable.
Ceriated tungsten can withstand higher temperatures and works very well with the new squarewave and inverter machines for the following reasons:
Holds a point longer and starts well at low amperages.
Can be used on both AC and DC polarities. When welding aluminum, it has become very acceptable to grind a point on ceriated tungsten (especially when welding on thinner materials).

Tungsten Carbide Threading Tools

Threading tools with a carbide end are often found in machine shops to cut metal. They are also called lathe tools and can be on an assortment of materials such as turret lathes, vertical turret lathes, engine lathes and chuckers.

Tungsten carbide threading tools come in both left- and right-hand versions and some suppliers will make custom-built ones per specified needs.

Tungsten Carbide Circular Saw Blades

Tubgsten carbide circular saw blades are sized to fit not only in industrial machinery but also in standard table saws and hand-held circular saws.

The most common tungsten carbide circular saw blades are not solid tungsten carbide; their body is typically tempered steel and only the cutting edges of the teeth are coated with tungsten carbide. A variation of the toothed saw blade is the grinding "wheel" or abrasive blade---still circular but without teeth.

Their edge is coated with tungsten carbide and used to exert abrasive force as they grind through stone, ceramics and metal.

Tungsten Carbide Indexable Cutting Tools Basic Knowledge

Now, tungsten carbide indexable cutting tools are using chemical vapor deposition method to depositing titanium carbide, titanium nitride, alumina hard layer or composite hard layer. The developping physical vapor deposition method not only can be used for the carbide cutting tools, but also can be used for high speed steel cutting tools, like drill bits, hobbing cutter, screw tap, milling cutter and so on. As a barrier for chemical diffusion and heat conduction, hard coating makes cutter-wear rate slower. Compared with no coating blade, the life of coating blade may improve more than 1-3 times.

Due to the application in high temperature, high pressure, high speed, and corrosive fluid medium parts, it is more and more difficult to machine materials, and the increasing demands for the automatic level of cutting process and machining precision. In order to adapt to this situation, the manufacturer should do something as follows: first of all, the development direction of cutting tools will use the new cutting tool matrials; second, to further develop vapor deposition technologies of cutting tool and higher hardness of the coating on the high strength and high wear resistance base would solve the problem between hardness and strength of cutting tools;third, to further develop the structure of tungsten carbide indexable cutting tools; fourth, to omprove the machining precision and reduce the difference between the product’s quality to make the use of cutting tools realize optimization.

How do I prepare welding joint?

1.Clean
Cleaning both the weld joint area and the filler metal is an important preparation. Remove all oil, grease, dirt, paint, etc. The presence of these contaminants may result in arc instability or contaminated welds.
2.Clamp
Clamping may be required if the work piece cannot be supported during welding.
3.Tack weld
Make short 1/4 in. tack welds along the work pieces to hold them together.
