Flaw detectors play a key role across the new energy industry chain:
1. Battery manufacturing: X-ray flaw detectors check the uniformity of lithium-ion battery electrode coatings and flag areas where thickness deviates by more than 5%; ultrasonic flaw detectors check the quality of electrode tab welds, reducing the cold-weld rate to 0.1%.
2. Photovoltaics: Eddy current flaw detectors find surface cracks on silicon ingots to avoid excessive breakage during cutting; ultrasonic flaw detectors find internal voids in photovoltaic ribbon to ensure conductivity.
3. Hydrogen energy equipment: X-ray flaw detectors find internal lack-of-fusion defects in the welds of high-pressure hydrogen storage tanks, meeting the requirements of ASME standards.
