When it comes to ensuring that defects in welds are detected in an assembly line, nondestructive testing (NDT) is an essential tool. Without a means of assessing potential errors in welds, welding would be risky business.
Not all NDT technologies are alike, however. Just as some techniques are becoming phased out, newer and more operator-friendly versions are taking their places. While welding defects aren’t changing, the materials used to complete the welds are, and therefore the NDT technologies continue to evolve.
