The main difference between an Overnight Certified Welding Inspector and a Certified Welding Inspector is the shift focus. The overnight role emphasizes night shift work, often in industries requiring continuous inspection, while the general CWI works during regular hours. Both roles require the same certification but differ mainly in work hours and environment.
