The heat treatment process used in Sa516 grad 70 plate is called normalizing.
Normalizing involves heating the plate to a temperature above its critical range and then cooling it in still air.
This process helps to refine the grain structure and improve the mechanical properties of the plate.
It also relieves internal stresses and enhances the plate's resistance to brittle fracture.
Normalizing is typically performed after...
No, Sa105 pipe does not have hard punch on the OD of the pipe.
Sa105 pipe is a carbon steel pipe used in high-pressure and high-temperature applications.
It is typically manufactured with smooth surfaces and no hard punches on the OD.
Any irregularities on the OD of the pipe can affect its performance and integrity.
Sa105 pipe is commonly used in the oil and gas industry for pipelines, refineries, and petrochemical plants.
The critical angle in UT process is the angle at which the sound wave is refracted instead of being reflected back.
Critical angle is the angle at which the sound wave is refracted instead of being reflected back
It is the angle at which the sound wave enters the material at a certain angle and is no longer able to continue through the material
It is important to know the critical angle in UT process to ensure accurate in...

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...
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 ...
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.

I applied via Walk-in and was interviewed in Jan 2022. There were 3 interview rounds.
I applied via Naukri.com and was interviewed before Nov 2022. There were 2 interview rounds.
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...

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
