may not be properly distributed through the material.

, How does welding on a vertical surface differ from welding on a horizontal surface?
✔✔Welding on a vertical surface requires more control to prevent the molten weld pool from
dripping, and may require slower travel speeds and different techniques than horizontal welding.
What is the significance of bead overlap in welding?
✔✔Bead overlap occurs when the weld bead flows over the base material without fusing
properly, which weakens the joint and can lead to failure under stress.
Why do some welds require post-weld cleaning?
✔✔Post-weld cleaning removes residual slag, oxide layers, or contamination, improving the
appearance and integrity of the weld, and preparing it for further inspection or coating.
What happens if the welding voltage is too high?
✔✔High welding voltage can result in excessive spatter, an unstable arc, and an overly wide or
shallow weld bead, weakening the weld joint.
How does a welder ensure proper joint fit-up?
✔✔Proper joint fit-up ensures that the pieces being welded are aligned correctly, reducing gaps,
improving the quality of the weld, and ensuring consistent fusion.
