Voltas Engineering Interview Questions, Process, and Tips

There are several types of welding, including MIG, TIG, Stick, Flux-Cored, and Arc 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 and a flux coating to create a strong bond between two metals.

• Flux-Cored welding uses a wire elect...read more

AHU stands for Air Handling Unit. It is responsible for circulating, filtering, and conditioning air in a building.

• AHU is a mechanical device that is used to regulate and circulate air in a building.

• It is responsible for filtering and conditioning the air to maintain a comfortable and healthy indoor environment.

• AHUs are commonly used in HVAC systems in commercial and industrial buildings.

• Examples of AHUs include roofto

After grill comes griddle, which is a flat cooking surface typically used for pancakes, eggs, and bacon.

• Griddle is a flat cooking surface made of cast iron, steel, or aluminum.

• It is typically used for cooking breakfast foods like pancakes, eggs, and bacon.

• Griddles can also be used for cooking burgers, sandwiches, and vegetables.

• Some griddles have a non-stick coating for easy cleaning.

• Griddles can be electric or gas-pow

Ducting system is a network of pipes used for ventilation, heating, and air conditioning.

• Ducting system is used to circulate air throughout a building or structure.

• It consists of a network of pipes, vents, and ducts that are connected to HVAC systems.

• Ducting systems can be made of various materials such as metal, fiberglass, or plastic.

• They can be designed for specific purposes such as exhaust ducts, supply ducts, or r...read more

Argon gas is used in TIG welding.

• TIG welding stands for Tungsten Inert Gas welding.

• Argon gas is used as a shielding gas to protect the weld from atmospheric contamination.

• Argon gas is preferred over other gases because it is inert and does not react with the metal being welded.

• Argon gas also helps to stabilize the electric arc and improve the quality of the weld.

• Other gases like helium or a mixture of argon and helium ...read more
