Base metals are also known as what?

Base metals refer to the fundamental metals that serve as the primary material in a fabrication or welding process. The term "parent metal" is typically used interchangeably with base metal to denote the original metal being welded or joined, which can include materials such as steel, aluminum, or other alloys upon which welds will be applied. Understanding this terminology is crucial in welding, as it helps in identifying the right techniques and materials needed for effective welding.

Weld metal, on the other hand, refers specifically to the metal that is deposited to create the weld joint itself. Filler metal is a related term, signifying the metal added to fill the joint during welding but does not encompass the structure of the base metal. Base alloy, while relevant to specific discussions in metallurgy, specifically pertains to a metal alloy that serves as a foundation for further processing or alloying, rather than the broader term for the metal being welded.

Recognizing the distinction between these terms is important when discussing welding procedures, specifications, and the properties of materials involved in the welding process.
