Systems and methods for non-destructively inspecting components

A method for a system comprising:

• a housing;
• an ultrasonic transducer secured within the housing;
• one or more barriers secured within the housing, wherein the one or more barriers are formed of a solid material;
• and
• a liquid retention chamber within the housing between the ultrasonic transducer and the one or more barriers, wherein the liquid retention chamber retains a liquid, and wherein a delay line is defined between the one or more barriers and the liquid within liquid retention chamber,
• the method comprising:
• emitting, by the ultrasonic transducer, ultrasonic signals into and through the delay line toward and into a component.

A system comprising:

• a housing configured to slide over a surface of a component;
• an ultrasonic transducer secured within the housing;
• one or more barriers secured within the housing, wherein the one or more barriers are formed of hard water;
• and
• a liquid retention chamber within the housing between the ultrasonic transducer and the one or more barriers, wherein the liquid retention chamber retains liquid water, and wherein a delay line is defined between the one or more barriers and the liquid water within liquid retention chamber.
