Non-Destructive Testing (NDT)
Non-destructive testing (NDT) evaluates the integrity of battery components — welds, enclosures, current collectors, and structural members — without damaging or consuming the part under inspection. As a hard skill it requires certification in and practical application of methods such as ultrasonic testing, radiographic inspection, dye-penetrant testing, and eddy-current scanning to detect cracks, voids, and delaminations in safety-critical joints. Quality engineers apply NDT to verify tab-to-busbar welds in cell assemblies, inspect pack enclosure welds for leak-risk defects, and assess incoming structural castings and forgings before they enter battery production.
