RF welding defects are particularly dangerous in supply chain terms because the most serious ones—cold welds especially—are invisible to standard visual inspection and only surface under field stress conditions, long after the container has left port. This guide covers the three defect types that experienced sourcing managers look for when auditing an OEM RF welding operation: incomplete molecular fusion (cold weld), thermal degradation from arcing, and asymmetrical extrusion from platen misalignment. For each defect it explains the production conditions that cause it, the visual and tactile indicators visible during a factory audit, and the specific test or documentation request that confirms or rules it out.
