Question

Quizplus · Accepted Answer

The root pass is the first pass in a weld joint and it fuses the two parts together, establishing the depth of weld metal penetration. The backing strip is a piece of material placed behind the joint to support the welding process and does not fuse the two parts together. The hot pass is a secondary pass used to refine the shape of the weld bead, and the cover pass is the final pass used to fill in any remaining gaps and smooth out the weld bead.
