Download Non-Destructive Testing of Welds

Welding processes and  methods can introduce contaminants and metallurgical defects into the weld.  If a weld is required to withstand severe loading conditions and stresses it is critical to insure its quality meets minimum standards.  Welds can be tested by destructive and non-destructive techniques.   Most production is tested by use of non-destructive methods.  The most common non-destructive tests to check welds are Visual Inspection, Liquid Penetrant, Magnetic Particle, Eddy Current, Ultrasonic, Acoustic Emission and Radiography.
