Which of the following might result in linear slag inclusions?
A) Improper shielding gas flow on a GTA weld
B) Wormholes
C) Making a SMA weld over a highly crowned previous weld
D) Too high of a welding current in the vertical up position

Question

Quizplus · Accepted Answer

Linear slag inclusions can occur when making a SMA weld over a highly crowned previous weld, as the crown can trap slag and prevent it from being fully removed. Improper shielding gas flow on a GTA weld can lead to porosity or lack of fusion, not linear slag inclusions. Wormholes can lead to small cavities in the weld, not linear slag inclusions. Too high of a welding current in the vertical up position can lead to undercut or burn-through, not linear slag inclusions.
