The weave bead width should be _____ the diameter of the electrode being used.

The weave bead width should be _____ the diameter of the electrode being used.

• A. The same as
• B. No wider than 2-3 times
• C. 4 times
• D. No wider than 6 times

Answer: (D)

Bead width is all about controlling heat input and how the weld fills the joint. When you weave, you need a bead that’s wide enough to cover the joint but not so wide that the heat is spread over a large area, which can cause burn-through, lack of fusion, or distortion. The guideline you’re tested on sets an upper limit: the weave bead width should be no wider than six times the diameter of the electrode being used. The electrode size relates to the current you’re delivering and how much metal you’re depositing, so keeping within this six-to-one ratio helps keep the heat concentrated enough for good fusion and a stable arc, while still allowing you to cover the joint effectively with a reasonable number of passes. Going wider than that risks overheating and the problems that come with it. The other options imply widths that are either too narrow or not aligned with the practical upper bound used in typical practice.
