Kirloskar Pneumatic QA QC Engineer Interview Questions, Process, and Tips

GD&T stands for Geometric Dimensioning and Tolerancing.

• GD&T is a system used to define and communicate engineering tolerances.

• It provides a standardized language for specifying the form, size, orientation, and location of features on a part.

• GD&T uses symbols, feature control frames, and datums to convey the desired tolerances and requirements.

• It ensures that parts are manufactured and inspected consistently, leading to...read more

QA QC is crucial in ensuring the quality and reliability of mechanical engineering products and processes.

• QA QC helps identify and prevent defects in mechanical engineering products and processes.

• It ensures compliance with industry standards and regulations.

• It helps improve efficiency and reduce costs by identifying areas for improvement.

• Examples include testing and inspecting mechanical components, monitoring producti...read more

Different measuring instruments and their least count, along with hands-on experience.

• Vernier caliper - 0.02 mm

• Micrometer screw gauge - 0.01 mm

• Dial gauge - 0.01 mm

• Height gauge - 0.02 mm

• Thread pitch gauge - 0.01 mm

• Using instruments requires proper calibration and handling

• Hands-on experience can be gained through practice and training

5S principles are Sort, Set in order, Shine, Standardize, and Sustain. Quality is important to ensure customer satisfaction and business success.

• Sort - eliminate unnecessary items to improve efficiency

• Set in order - organize items for easy access and productivity

• Shine - maintain cleanliness and prevent defects

• Standardize - establish consistent processes for quality control

• Sustain - continuously improve and maintain the...read more

There are several types of welding, including MIG, TIG, Stick, and Flux-Cored welding.

• MIG (Metal Inert Gas) welding uses a wire electrode and a shielding gas to join two pieces of metal together.

• TIG (Tungsten Inert Gas) welding uses a tungsten electrode and a shielding gas to create a precise and clean weld.

• Stick welding (also known as Shielded Metal Arc Welding) uses a consumable electrode coated in flux to create a s...read more

Spatter is formed while welding due to the expulsion of molten metal from the weld pool.

• Spatter is caused by the high temperature of the welding process.

• It can be reduced by adjusting the welding parameters such as voltage, current, and wire feed speed.

• Using a welding gun with a shorter nozzle can also help reduce spatter.

• Spatter can cause defects in the weld and may need to be removed before finishing.

• It can also be a

Welding defects include porosity, cracks, incomplete fusion, and distortion. Measures to reduce defects include proper training, inspection, and maintenance.

• Porosity: caused by gas entrapment, can be reduced by proper shielding gas and electrode selection

• Cracks: caused by high stress or improper cooling, can be reduced by preheating and controlling cooling rate

• Incomplete fusion: caused by insufficient heat or improper ...read more

Types of fit include clearance fit, interference fit, and transition fit.

• Clearance fit: parts have a gap between them

• Interference fit: parts are pressed or forced together

• Transition fit: parts have both clearance and interference

• Examples: piston and cylinder, gears and shafts
