NDE acceptance criteria are the standards used to determine the acceptability of non-destructive examination results.
NDE acceptance criteria vary depending on the type of examination being performed.
Criteria may include minimum detectable flaw size, maximum allowed defect size, and location of defects.
Acceptance criteria are typically specified in codes and standards such as ASME, API, and AWS.
Examples of NDE acceptanc...

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...
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...
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...
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...
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 ...
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

Refrigeration cycle is a thermodynamic cycle used in refrigerators and air conditioning systems to transfer heat from a low temperature reservoir to a high temperature reservoir.
Consists of four main components: compressor, condenser, expansion valve, and evaporator
Refrigerant is compressed in the compressor, then condensed in the condenser, expanded in the expansion valve, and evaporated in the evaporator
Heat is absor...
Refrigeration theory involves the transfer of heat from a low temperature region to a high temperature region using a refrigerant.
Refrigeration is based on the principles of thermodynamics, specifically the second law which states that heat naturally flows from a higher temperature to a lower temperature.
The refrigeration cycle consists of four main components: compressor, condenser, expansion valve, and evaporator.
The...
I applied via Referral and was interviewed before Sep 2023. There was 1 interview round.
A resistor is an electronic component that resists the flow of electrical current.
Resistors are used to control the amount of current flowing in a circuit.
They are measured in ohms (Ω) and have color-coded bands to indicate their resistance value.
Resistors dissipate energy in the form of heat when current flows through them.
Common types of resistors include carbon film, metal film, and wirewound resistors.
A transistor is a semiconductor device used to amplify or switch electronic signals.
Transistors are fundamental building blocks of modern electronic devices.
They can amplify electrical signals, control the flow of current, and act as switches.
Common types of transistors include bipolar junction transistors (BJTs) and field-effect transistors (FETs).
I applied via Campus Placement and was interviewed before Mar 2021. There was 1 interview round.

I applied via Walk-in and was interviewed in Nov 2020. There was 1 interview round.
Moulding defect refers to any imperfection or flaw in the manufacturing process of moulded products.
Moulding defects can occur due to various reasons such as improper material flow, inadequate cooling, or incorrect mould design.
Examples of moulding defects include flash, sink marks, warpage, voids, and short shots.
Flash occurs when excess material escapes from the mould, resulting in a thin layer of material around the...
Silver marks can be controlled by using protective coatings and proper cleaning techniques.
Apply a protective coating, such as lacquer or wax, to prevent silver from tarnishing
Store silver items in airtight containers or with anti-tarnish strips to minimize exposure to air
Avoid contact with substances that can cause silver to tarnish, such as sulfur-containing materials
Clean silver regularly using gentle methods, such ...
