TÜV NORD Tpi Inspection Engineer Interview Questions and Answers

Valves are mechanical devices used to control the flow of fluids within a system. They can be classified into different types based on their design and function.

• Gate valves: used to fully open or close the flow of fluid

• Ball valves: have a spherical closure element to control flow

• Check valves: allow flow in one direction only to prevent backflow

• Butterfly valves: have a disc that rotates to control flow

• Pressure relief va...read more

Defects in welding can compromise the integrity of the joint and lead to structural failures.

• Common welding defects include porosity, lack of fusion, cracks, and undercutting.

• Porosity is caused by gas entrapment during the welding process.

• Lack of fusion occurs when the weld metal fails to fuse with the base metal.

• Cracks can result from excessive stress or improper cooling of the weld.

• Undercutting is a groove formation ...read more

The tolerance of UT test refers to the acceptable range of error in the test results.

• Tolerance is typically specified in the testing standards or procedures.

• It is important to ensure that the equipment used for UT testing is calibrated within the specified tolerance limits.

• Deviation from the tolerance range may indicate a need for retesting or further investigation.

• Examples of tolerance limits for UT testing may includ

WPS stands for Welding Procedure Specification and PQR stands for Procedure Qualification Record.

• WPS is a document that provides detailed welding instructions and parameters for a specific welding job.

• PQR is a record of the welding parameters used during the qualification of a welding procedure.

• WPS and PQR are essential documents in the welding industry to ensure quality and consistency in welding processes.

The gap required in fit-up of pipes depends on the welding process and material being used.

• The gap for TIG welding is typically 1/16 to 1/8 inch.

• For MIG welding, the gap can be slightly larger, around 3/32 to 1/8 inch.

• The gap should be uniform along the entire length of the joint for proper welding.

• The material being welded also influences the gap size, with thicker materials requiring larger gaps.

IQI stands for Image Quality Indicator, used in radiography testing to ensure the quality of the radiographic image.

• IQI is a tool used to determine the quality of radiographic images by measuring the image quality parameters such as contrast, resolution, and sensitivity.

• It consists of a series of patterns or objects with specific details that are placed on the radiographic film along with the test object.

• The IQI is the...read more

RT and UT are non-destructive testing methods used in inspection to detect flaws in materials.

• RT stands for Radiographic Testing, which uses X-rays or gamma rays to inspect the internal structure of materials.

• UT stands for Ultrasonic Testing, which uses high frequency sound waves to detect flaws or measure thickness in materials.

• RT is commonly used for detecting internal defects in welds, castings, and forgings.

• UT is o...read more

Valves are devices used to control the flow of fluids or gases in a system.

• Gate valve: used to start or stop the flow of fluid by lifting or lowering a gate

• Ball valve: uses a rotating ball with a hole to control the flow

• Check valve: allows flow in one direction and prevents backflow

• Globe valve: controls flow by raising or lowering a disc against the flow

• Butterfly valve: uses a disc to control flow by rotating it

QAP, WPS, and DFT are important documents used in inspection engineering.

• QAP stands for Quality Assurance Plan, which outlines the procedures and requirements for ensuring quality in a project or process.
