Bureau Veritas Inspection Engineer Interview Questions, Process, and Tips

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

The instrument used for surface preparation is a sandblaster.

• Sandblaster is commonly used for surface preparation in industries like construction, automotive, and shipbuilding.

• It uses compressed air to propel abrasive material at high velocity to smooth out rough surfaces or remove contaminants.

• Examples of abrasive materials used in sandblasters include sand, garnet, and glass beads.

Types of welding include arc welding, gas welding, resistance welding, and laser welding.

• Arc welding: uses an electric arc to melt and join metals, such as MIG welding and TIG welding

• Gas welding: uses a gas flame to melt and join metals, such as oxyacetylene welding

• Resistance welding: uses electric resistance to generate heat and join metals, such as spot welding

• Laser welding: uses a high-powered laser beam to melt and

Ultrasonic Testing (UT) is used to measure sub surface defects below 12mm.

• Ultrasonic Testing (UT) is a non-destructive testing method that uses high frequency sound waves to detect internal flaws in materials.

• UT is commonly used in industries such as aerospace, automotive, and manufacturing to inspect for defects like cracks, voids, and inclusions.

• The technique is effective for detecting sub surface defects as it can p...read more

X-ray film is commonly used for radiography testing.

• X-ray film is sensitive to X-ray radiation and produces an image when exposed.

• The film is placed behind the object being tested and exposed to X-rays.

• After exposure, the film is developed to reveal any defects or abnormalities.

• Common types of X-ray film include industrial radiographic film and medical radiographic film.

Pipe is measured by its inner diameter, while tube is measured by its outer diameter.

• Pipe is used to transport fluids or gases, while tube is often used for structural applications.

• Pipe is typically manufactured to specific industry standards, while tube may have more varied dimensions and tolerances.

• Examples: PVC pipe for plumbing, steel tube for construction.

Five important IS codes related to inspection engineering

• IS 456: Code of practice for plain and reinforced concrete

• IS 3370: Code of practice for concrete structures for storage of liquids

• IS 800: Code of practice for general construction in steel

• IS 1893: Criteria for earthquake resistant design of structures

• IS 875: Code of practice for design loads for buildings and structures

The hydrotest pressure of a vessel with MAWP=1MPa is typically 1.5 times the MAWP.

• Hydrotest pressure is usually 1.5 times the MAWP (Maximum Allowable Working Pressure)

• For MAWP=1MPa, the hydrotest pressure would be 1.5 MPa

• Hydrotest pressure ensures the vessel's structural integrity under pressure

ASME B31.3 is the code used for transportation of Hydrocarbon Fluids as per ASME Sec VIII Div.1.

• ASME B31.3 code is used for transportation of Hydrocarbon Fluids

• ASME Sec VIII Div.1 is for pressure vessels, not transportation

• Examples: ASME B31.3 code is used for pipelines carrying hydrocarbon fluids
