Cerium tungsten electrode is a tungsten electrode containing about 2% cerium oxide, which is called cerium tungsten electrode in English. The color code applicator is gray. Thorium tungsten electrode is a tungsten electrode containing 1-1.2% thorium oxide, which is called Thoriated Tungsten Electrode in English. The color code coating heads are yellow, red, purple and orange.
Tungsten copper alloy combines the advantages of tungsten and copper, high temperature resistance, arc ablation resistance, high hardness, high melting point, high strength, high specific gravity, high electrical conductivity, high thermal conductivity, easy cutting, anti-adhesion, and has the characteristics of sweating and cooling.
Pure tungsten electrode is an electrode product with refractory metal tungsten as the main raw material. It is the earliest electrode used in argon arc welding.
Metal tungsten has the characteristics of high melting point, strong electron emission ability and low vapor pressure, making it the preferred thermionic emission material.
Compared with traditional electrode materials, tungsten-based electrode materials have the characteristics of high melting point, good corrosion resistance, high density, and superior thermal and electrical conductivity, so they are widely used in the field of welding.
The powder particle size and uniformity of tungsten powder and copper powder will affect the sintering effect of tungsten-copper alloy electrode to a certain extent. The reduction of powder particle size will make the comprehensive properties of materials such as density, hardness etc.
The morphological distribution of the tungsten-copper powder sintered material is uniformly distributed on the copper substrate with tungsten as a skeleton. Due to the high melting point and high hardness of tungsten W, the ultimate tensile strength of tungsten at 1000 ° C is still 50kgf / mm2
The tungsten copper powder sintered material is distributed in the form of tungsten as the skeleton evenly on the copper matrix. Due to the high melting point and high hardness of tungsten W, tungsten at 1000 ℃, its ultimate tensile strength is still 50kgf / mm2, higher than the strength of low-carb
