Question

When a larger (3/32"" to 1/8"") wire electrode diameter is used, the width of a stringer bead is generally no more than _____ times the wire electrode's diameter.

A. 1.5
B. 2
C. 2.5
D. 3

Answer 1

The width of a stringer bead is generally no more than 3 times the diameter of a wire electrode when using a larger wire electrode diameter.

Step-by-step explanation:

When a larger wire electrode diameter, ranging from 3/32"" to 1/8"", is used in welding, the width of a stringer bead is generally no more than 3 times the wire electrode's diameter. Therefore, the answer to the student's question is D. 3.
