Understanding Weld Reinforcement
In welding, the height of the weld above the base metal in a groove weld is referred to as weld reinforcement. This term describes the extra material added during the welding process, which extends above the surface of the base metal and provides strength to the weld joint. Its purpose is to increase the durability and fatigue resistance of the weld.
