What is the correct width of a weave bead?

1 X bare electrode diameter
2-3 X bare electrode diameter
4-5 X bare electrode diameter
5-6 X bare electrode diameter

The correct answer is: 2-3 X bare electrode diameter

A is incorrect because it is too narrow and can lead to poor penetration. C is incorrect because it is too wide and can result in uneven bead formation. D is incorrect because it is also too wide and can cause excessive heat input and potential burn-through. The correct width for a weave bead is 2-3 times the bare electrode diameter, as it allows for proper heat distribution and fusion between the base metal and filler metal. This width also promotes a consistent and uniform bead profile.
