Lack of fusion
Problems with lack of fusion between weld and parent metal have different reasons.
Incorrectsetting. Low voltage or long electrode stick-out will result in welding where
the added heat is notin proportion to the amount of filler material.
If the melted metal in the pool tends to flow before the arc. This can be caused if the
weld is sloping, and if the welding torch is not properly aligned with the direction of
the weld. The problem will also be worse if there is a large weld pool as a result of
high heat input and slow travel speed of the welding torch.
The large thermal dissipation at thick workpieces.
