To identify counterfeit tungsten electrode products, we can start from the following aspects:
Visual Inspection
whether the packaging is formal, whether there is a clear factory label, model and specification description;
whether the electrode surface is smooth and uniform, without obvious defects, cracks or impurities;
Whether the color and identification ring are consistent with the regular product (such as thorium tungsten electrodes generally have red rings).
Component And Performance Testing
Chemical analysis was used to detect whether the content of tungsten and doped elements met the standard;
Physical property testing, such as hardness and density to meet standards;
Arc initiation performance and arc stability testing.
Packaging & Certification
Check if there are relevant quality certifications (ISO, RoHS, etc.);
Check the production batch number and factory inspection report.
Purchase Channels
Give priority to regular manufacturers and authorized agents to buy;
Be wary of low-priced and unqualified suppliers.
Usage Performance
Counterfeit products have a lot of splashing, short life, and easy to break when welding;
Difficult arcing, unstable welding arc.
Detection Tool Assistance
High-end detection equipment such as X-ray fluorescence (XRF) analyzers and scanning electron microscopy (SEM) are used to identify components and microstructures.
