The Shape of Strength: Weld Bead Profile
The shape of the final weld bead is not just about aesthetics; it's a critical indicator of the weld's quality and mechanical properties. The ideal profile for most applications is a flat or slightly convex bead with smooth transitions ("tie-in") to the base metal.
- Convex Bead: A bead that is too "ropey" or convex may have poor fusion at the toes of the weld. It's often caused by low voltage or slow travel speed.
- Concave Bead: A bead that sags in the middle is concave. While sometimes acceptable, excessive concavity can reduce the throat thickness of the weld, making it weaker. It's often caused by high voltage or fast travel speed.
