Deepsolv Interview Questions and Answers
Q1. Least count of vernier calliper , micrometre .
The least count of a vernier calliper and micrometre refers to the smallest measurement that can be accurately read on the instrument.
The least count of a vernier calliper is typically 0.02 mm or 0.001 inches.
The least count of a micrometre is typically 0.01 mm or 0.001 inches.
The least count is determined by the number of divisions on the main scale and the vernier scale.
For example, if the main scale has divisions of 1 mm and the vernier scale has 50 divisions, the least co...read more
Q2. Vernier caliper least count ?
The least count of a Vernier caliper is the smallest measurement that can be read on the scale.
The least count is determined by the number of divisions on the main scale and the Vernier scale.
It is calculated by dividing the smallest division on the main scale by the total number of divisions on the Vernier scale.
For example, if the smallest division on the main scale is 0.1 mm and the total number of divisions on the Vernier scale is 10, the least count would be 0.01 mm.
Q3. What is tolerance ?
Tolerance refers to the allowable variation or deviation from a specified dimension or value.
Tolerance is important in manufacturing to ensure that parts and components fit together properly.
It is expressed as a range or limit within which a dimension or value can vary.
Tolerance can be specified for various parameters such as size, shape, weight, temperature, etc.
For example, if a machine part has a tolerance of ±0.1mm, it means that the actual dimension can vary by up to 0.1...read more
Q4. Micrometer least count?
The least count of a micrometer is the smallest measurement that can be read on the micrometer scale.
The least count is determined by the number of divisions on the micrometer scale and the pitch of the screw.
It is usually expressed in micrometers or millimeters.
For example, if a micrometer has 50 divisions on the scale and the pitch of the screw is 0.5 mm, the least count would be 0.01 mm (0.5 mm / 50 divisions).
Q5. Differentiate arc , spot welding etc.
Arc welding uses an electric arc to melt and join metals, while spot welding uses pressure and heat to join two metal surfaces.
Arc welding involves creating an electric arc between an electrode and the metal being welded, which melts the metal and fuses it together.
Spot welding involves applying pressure and heat to two metal surfaces, which creates a small weld at the point of contact.
Arc welding is typically used for thicker metals and can be done with a variety of welding ...read more
Q6. Types of welding
There are several types of welding, including MIG, TIG, Stick, and Flux-Cored welding.
MIG welding uses a wire electrode and a shielding gas to join two pieces of metal together.
TIG welding uses a tungsten electrode and a filler metal to create a strong bond between two metals.
Stick welding uses a consumable electrode coated in flux to create an arc and join two metals together.
Flux-Cored welding uses a wire electrode with a flux core to create a protective shield around the w...read more
