The material of manufacturing the tool must have high temperature hardness and wear resistance, the necessary bending strength, impact toughness and chemical inertness, for good process, usually when the hardness is high, wear resistance is also high; high bending strength is with impact toughness. However, the higher the hardness is, the lower the flexural strength and impact toughness are. Tungsten carbide is a widely used tool material. Tungsten carbide indexable inserts are now coated with titanium carbide by chemical vapor deposition of titanium nitride, alumina hard layer or composite hard layer. Developing physical vapor deposition method can be used for carbide tool.

Tungsten carbide rod is tungsten carbide cutting tools, which applies different coarse grinding parameters, cutting materials and non-metallic materials. Meanwhile, the tungsten carbide rod can also be applied to a conventional automatic, semi-automatic lathe, and so on. The main process is milling → formula according to the intended use →wet milling →mixing →smashing →drying → sifting → crush → drying → mixed sieved and then drying → mix → granulation suppress → forming → low pressure burning → forming → ??cylindrical grinding fine grinding → packaging →detection size →putting in storage.

Welding procedure variables control the welding process and the quality of the welds produced. Joint configuration is determined by the design of the weldment, the metallurgical analysis, and by the process and procedure required by the weldment.

Welding variables are selected after the base metal, filler metal, and joint configuration have been selected. The fixed welding variables include the type of filler metal, electrode type and size, the type of current, and the type of shielding gas.

The adjustable variables control the shape of the weld by affecting things such as bead height, bead width, penetration, and weld integrity. The primary adjustable variables for GTAW are welding current, arc length, and travel speed.

Secondary variables also aid in controlling the welding process, but it is more difficult to calculate the extent of effect. The secondary variables include work and travel angle and the distance the electrode extends beyond the end of the cup.
