1. A system for ultrasonic profiling of a weld sample, the system comprising:

  • a translation element movable in opposite first and second directions;

    a sensor coupled to the translation element to move over a weld sample as the translation element moves, wherein the sensor is operable to take ultrasonic measurements of the weld sample;

    an encoder operable for determining the position of the translation element, wherein the encoder determines the position of the sensor from the position of the translation element; and

    a spring connected at one end of the translation element, wherein upon the translation element being moved in the first direction toward the spring such that the translation element and the sensor are at a beginning position relative to the weld sample and the spring is compressed the spring decompresses to push the translation element back along the second direction to move the translation element and the sensor from the beginning position to an ending position relative to the weld sample;

    wherein the encoder triggers the sensor to take the ultrasonic measurements of the weld sample when the sensor is at predetermined positions relative to the weld sample while the sensor moves over the weld sample from the beginning position to the ending position.
