Nondestructive Testing: Overview

Nondestructive Testing Systems for In-line Real Time Quality Assurance During Manufacture


Quality assurance programs are commonly based on off-line testing of selected samples of products or product components as they move along, or emerge from, the manufacturing process. Statistical methods are then applied to the test results to determine the probability of a defective unit being shipped to the customer. In such a QA process, money saved by not testing every product item can be quickly lost to systematic errors that may not be detected until late in a production run.

Enerize believes that in-line testing of every product unit at several points during production can be a cost effective and quality effective approach to quality control. Such measures are especially important in cases where products may be mission-critical or where repair or replacement would be unduly expensive. Enerize NDT technologies allow 100% nondestructive quality control in real time in the production of batteries, fuel cell, solar cells, supercapacitors etc.

In general, physical nondestructive non-contact quality assurance methods have a number of major advantages over other methods and equipment for testing seals in batteries, electric double layer capacitors (supercapacitors), fuel cells, solar cells and the like. These include: 


  • Reliability due to the non-contact operation,

  • Cost effective in operation,

  • Relatively inexpensive to implement,

  • Readily automated with results obtained in near real-time,

  • Safe and less expensive than x-ray methods,

  • Precise determination of specific defects,

  • Provides for 100% nondestructive quality assurance of the end product.
