The process of joining two pieces of metal using heat and pressure is known as welding. Welding involves melting the base metal with a heat source, which often includes an electrode or filler material, to create a strong bond as the metal cools and solidifies. This technique is widely used in various applications due to its ability to create durable and permanent joints.

Welding is distinguished from other joining processes like brazing and soldering, which use lower temperatures and do not involve melting the base metal—only the joining material is melted in those processes. Additionally, riveting involves mechanical fasteners and does not use heat as a primary joining method. This makes welding a distinct and critical process in metal fabrication and structural applications.
