Red Seal Welding Practice Exam

Generally, what is the rule of thumb for stickout for SAW?

1. 8 times wire diameter

2. 6 times wire diameter

3. 10 times wire diameter

4. 4 times wire diameter

The correct answer is: 8 times wire diameter

The general rule of thumb for stickout for SAW (Submerged Arc Welding) is 8 times the wire diameter. This means that the electrode should be extended 8 times the diameter of the welding wire from the contact tip to the workpiece. This is important in order to achieve proper penetration and avoid creating excessive spatter. Option B and D are incorrect because they suggest a stickout that is either too short or too long, which can result in poor weld quality. Option C is also incorrect as it is not in line with the standard rule of thumb for stickout in SAW.
