Question

too slow of a travel speed can lead to what discontinuities

□ excessive reinforcement

□ cold lap

■ undercut

□ irregular weld profile

question 26

what is the general rule for setting your arc length?

○ it is no more than the size/diameter of the electrode

○ it is 1/2 of the size/diameter of the electrode

○ it is twice the size/diameter of the electrode

○ no more than 1.5 times the size/diameter of the electrode

Explanation:

In welding, the general rule for arc length is based on electrode size. A longer arc can cause instability and spatter, while a shorter arc is more controlled. The rule "it is no more than the size/diameter of the electrode" helps maintain a proper arc - electrode relationship for good weld quality.

Answer:

it is no more than the size/diameter of the electrode
