Question

Accepted Answer

Welding is a process of joining two materials together by melting them at the joint and allowing them to cool and solidify.

Welding works by creating a strong bond between two materials through the application of heat.
The heat melts the materials at the joint, allowing them to mix and form a solid connection when cooled.
Different welding techniques include arc welding, MIG welding, TIG welding, and spot welding.
Earthing is used in welding to provide a safe path for the electrical current to flow, preventing electric shocks and ensuring proper functioning of the welding equipment.
Favorite subject could be mechanical engineering, where basics include mechanics, thermodynamics, and materials science.
