NDT Multi Technician Interview Questions and Answers

Ultrasonic testing gauges the remaining life of a component by analyzing the thickness and integrity of the material.

• Measure thickness of material using ultrasonic waves

• Analyze any defects or corrosion present in the material

• Compare results with industry standards to determine remaining life

• Consider factors like material type, operating conditions, and previous maintenance history

• Provide recommendations for repair or replacement based on findings

Acceptance criteria for magnetic particle testing are based on industry standards and specifications.

• Acceptance criteria are determined by the relevant industry standards and specifications

• Criteria may include size, shape, location, and quantity of indications

• Acceptance criteria may vary depending on the material being tested and the specific application

• Examples of standards include ASTM E1444, ASME Section V, and ISO 9934

DPT test acceptance criteria are based on the size, shape, and location of indications found during the test.

• Acceptance criteria may vary depending on the specific code or standard being followed.

• Indications that exceed the specified size, shape, or location criteria may result in rejection of the component.

• Acceptance criteria are typically outlined in the procedure or specification for the DPT test.

• Examples of acceptance criteria include maximum allowable indication size, di...read more

NDT stands for Non-Destructive Testing. It is a method of testing materials without damaging them.

• NDT is used to detect flaws or defects in materials or structures

• It is commonly used in industries such as aerospace, oil and gas, and manufacturing

• Examples of NDT methods include ultrasonic testing, radiography, and magnetic particle inspection
