10+ Quality Assurance & Quality Control Interview Questions and Answers

Gas welding has advantages over arc welding in terms of portability, versatility, and control. It is commonly used in industries like automotive and construction.

• Gas welding is portable and does not require electricity, making it suitable for remote locations or areas with limited power supply.

• Gas welding is versatile and can be used to join a wide range of materials, including steel, aluminum, and copper.

• Gas welding provides better control over the heat input, allowing for p...read more

Flux is used in welding rods to protect the weld from atmospheric contamination and to facilitate the welding process.

• Flux acts as a shield, preventing the weld from reacting with oxygen and nitrogen in the air.

• It forms a protective layer called slag, which floats on top of the molten metal and prevents impurities from entering the weld.

• Flux also helps in removing oxides and other impurities from the metal surface, ensuring a clean and strong weld.

• Different types of flux are ...read more

The carbon attached in ethane is a saturated carbon atom bonded to two other carbon atoms.

• Ethane is a hydrocarbon with the chemical formula C2H6

• It is a simple alkane with two carbon atoms and six hydrogen atoms

• The carbon atoms in ethane are both sp3 hybridized and are bonded to each other by a single covalent bond

• Each carbon atom is also bonded to three hydrogen atoms

There are several types of welding, including arc welding, gas welding, and resistance welding.

• Arc welding uses an electric arc to melt and join metals.

• Gas welding involves using a flame from a gas source to melt and join metals.

• Resistance welding uses the heat generated by resistance to electric current to join metals.

• Other types of welding include laser welding, electron beam welding, and friction welding.

Equalizing quality head and attender is the worst HR policy.

• This policy undermines the importance of the quality head's role and expertise.

• It can lead to confusion and lack of clarity in decision-making.

• It can also demotivate the quality head and reduce their job satisfaction.

• This policy can negatively impact the overall quality of the organization's products or services.

• Examples of better HR policies include clear job descriptions, fair compensation, and opportunities for pr...read more

Water purification is the process of removing contaminants from water to make it safe for consumption.

• Water is purified through various methods such as filtration, sedimentation, and disinfection.

• Common contaminants removed during purification include bacteria, viruses, chemicals, and minerals.

• Purified water is used for drinking, cooking, and other household purposes.

• Water purification is also important for industrial and agricultural applications.

• Examples of water purificati...read more

The core tool of quality is the quality control chart.

• Quality control chart is a graphical tool used to monitor and control the quality of a process.

• It helps in identifying and analyzing variations in the process and taking corrective actions.

• Examples of quality control charts include control charts for variables (e.g., X-bar and R charts) and control charts for attributes (e.g., p and c charts).

Six Sigma is a data-driven methodology used to improve business processes by reducing defects and variability.

• Six Sigma aims to achieve near-perfect quality by minimizing process variation.

• It uses statistical analysis to identify and eliminate the root causes of defects.

• The goal is to achieve a process capability of 6 standard deviations between the mean and the nearest specification limit.

• Six Sigma projects follow a structured approach known as DMAIC: Define, Measure, Analyz...read more

Mortality refers to the state of being subject to death or the number of deaths in a population.

• Mortality is a measure of the number of deaths in a population over a specific period of time.

• It is often expressed as a mortality rate, which is the number of deaths per unit of population.

• Mortality can be influenced by various factors such as age, gender, genetics, lifestyle, and environmental factors.

• In medical terms, mortality is often used to refer to the death rate of patient...read more
