QA stands for Quality Assurance.
QA is a process of ensuring that products or services meet the desired quality standards.
It involves monitoring and evaluating the entire production process.
QA helps to identify and correct any defects or errors in the product or service.
It also involves creating and implementing quality control procedures.
Examples of QA include testing software for bugs, inspecting products for defects,
Bearings are used to reduce friction between two moving parts. There are different types of bearings for different applications.
Bearings reduce friction and wear between two moving parts
They support radial and axial loads
Types of bearings include ball bearings, roller bearings, and plain bearings
Ball bearings are used in high-speed applications
Roller bearings are used in heavy-duty applications
Plain bearings are used i
Mechanical seals are used to prevent leakage of fluids in rotating equipment such as pumps and compressors.
Mechanical seals are used to prevent leakage of fluids in rotating equipment
They consist of two main components - a stationary part and a rotating part
The stationary part is fixed to the pump or compressor housing, while the rotating part is attached to the shaft
The two parts are held together by a spring and a se...

Lubrication is essential for equipment and instrument maintenance. The type of lubricant used depends on the equipment and its operating conditions.
Lubrication reduces friction and wear on moving parts
Different types of lubricants include oil, grease, and dry lubricants
The type of lubricant used depends on the equipment's operating conditions, such as temperature and pressure
Over-lubrication can be just as harmful as u...
Measuring systems in mechanical engineering are used to accurately measure physical quantities such as length, force, pressure, and temperature.
Measuring systems can be analog or digital.
Analog measuring systems use a scale and pointer to indicate the measured value.
Digital measuring systems use electronic sensors to convert physical quantities into digital signals.
Common types of measuring systems include micrometers,...

I was interviewed before Jul 2016.
I was interviewed in Sep 2016.
Pneumatic systems use compressed air to transmit power, while hydraulic systems use fluid to transmit power.
Pneumatic systems use air as the working fluid, while hydraulic systems use liquid.
Pneumatic systems are typically used for lighter loads and faster movements, while hydraulic systems are used for heavier loads and slower movements.
Pneumatic systems are generally less expensive and easier to maintain compared to ...
There are several types of welding techniques used in various industries.
Arc welding: Uses an electric arc to create heat and join metals.
MIG welding: Uses a consumable wire electrode and shielding gas to join metals.
TIG welding: Uses a non-consumable tungsten electrode and inert gas to join metals.
Spot welding: Joins metal sheets by applying pressure and heat at specific points.
Flux-cored arc welding: Similar to MIG w...
CNC and lathe machines are used for precision cutting and shaping of materials.
CNC machines use computer programming to control the cutting tools, allowing for highly precise and complex shapes to be created.
Lathe machines are used for turning and shaping cylindrical objects, such as metal rods or wooden dowels.
Both machines are commonly used in manufacturing and engineering industries.
Examples of products made using C...
