Intertek Senior Inspection Engineer Interview Questions, Process, and Tips

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.
