There are indeed low-priced and low-quality tungsten electrodes on the market, and the main manifestations and risks include:
Poor Quality Of Raw Materials
Use low-purity tungsten powder or recycled materials, high impurity content;
Affect the high temperature resistance and electron emission ability of the electrode.
The Powder Metallurgy Process Is Not Standardized
Insufficient sintering, high porosity, low mechanical strength;
It is easy to crack and break, and has a short service life.
Insufficient Dopant Content Or Uniformity
Doped with thorium, lanthanum, cerium and other elements are not up to standard or unevenly distributed;
It leads to unstable arcing, unconcentrated arcing, and excessive splashing.
Poor Surface Treatment
The surface is rough and impurities, which affects the arcing performance and welding quality of the electrode.
Packaging And Labeling Are Not Standardized
There is no formal brand or testing certification, and there are many counterfeit and shoddy products.
Risks And Impacts:
The use of low-quality tungsten electrodes can lead to large weld splash, poor weld quality, short electrode life, and even production downtime and safety hazards, increasing maintenance costs.
