Welding symbols are standardized notations used in engineering and construction drawings to convey specific information about welding processes. These symbols provide details such as the type of weld, its size, and any additional requirements, ensuring that welders understand the expectations for each joint. Each welding symbol consists of a basic shape, often accompanied by arrows and other markings. The symbol's position relative to the reference line indicates whether the weld is to be made on the arrow side or the other side of the joint. Understanding these symbols is essential for achieving quality and consistency in welded structures.
