The melt-through symbol is used only when complete root penetration plus visible root reinforcement is required in welds made from one side only.
Melt-Through Symbol
A symbol in welding used to denote the requirement for full penetration of the weld, ensuring the weld material extends through the thickness of the parts being joined.
Root Penetration
The depth to which weld material extends into the base material at the root of the joint, crucial for joint strength.
Root Reinforcement
Additional material added at the root of a weld joint to ensure the joint has sufficient thickness and strength.
