Red Seal Welding Practice Exam 2026 – The All-In-One Guide to Exam Success!

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.
