Red Seal Welding Practice Exam

In SAW using 1/16 wire, what's the proper stickout?

1. 1/4"

2. 1/2"

3. 3/4"

4. 1"

The correct answer is: 1/2"

When using 1/16 wire for submerged arc welding (SAW), the proper stickout should be 1/2". This is because SAW requires a shorter stickout as compared to other welding processes. Stickout is the length of wire protruding from the nozzle to the workpiece. Option A of 1/4" is too short and can result in the wire sticking to the workpiece, causing issues with the weld bead shape. Option C and D of 3/4" and 1" are too long and can result in excessive flux covering the weld bead, leading to poor weld quality. Therefore, the most suitable option is B with 1/2" stickout.
