Base metals are also known as what?

Base metals are commonly referred to as parent metals. This term emphasizes that base metals serve as the primary material in welding and fabrication processes, providing the foundational structure to which additional materials, such as fillers or coatings, may be applied. The parent metal is the primary metal being welded or joined.

Understanding this terminology is crucial, particularly in the context of welding, as the properties of the base metal (such as its composition, strength, and thermal conductivity) significantly influence the overall quality and performance of the weld. The knowledge of parent metals is essential for selecting appropriate welding techniques, filler materials, and the required pre- and post-weld treatments to ensure the integrity of the weld joint.
