What weld bead characteristic is associated with a blunter point (60 degrees) vertex angle?

The characteristic of a weld bead associated with a blunter point, specifically a vertex angle of 60 degrees, typically produces a narrow bead width with deeper penetration. This is because a blunter point permits better control over the heat input as the arc can be more focused. This focused heat allows for the molten metal to reach deeper into the workpiece, creating a penetration profile that is advantageous for achieving strong welds, especially in thicker materials.

In contrast, a sharper angle would tend to produce a different heat distribution that might lead to wider beads with shallower penetration, making the choice of the vertex angle an important consideration in welding for controlling both bead shape and penetration depth. When welding, understanding how the angle affects the welding process is critical, as it directly influences the strength and integrity of the weld created.
