Study Notes
Welding Discontinuities and Terminologies
-
Excessive Weld Reinforcement: Known as "weld overbuild," refers to an excessive amount of weld material that can adversely affect the performance and aesthetics of the weld joint.
-
Lack of Fusion: This discontinuity occurs when there is insufficient bonding between the weld metal and the base metal, compromising the integrity of the joint.
-
Misalignment: A discontinuity caused when the surfaces being joined are not properly aligned, leading to uneven weld penetration and potential structural weaknesses.
-
Gas Pockets: Also known as porosity, this discontinuity results from gas trapped in the weld metal as it solidifies, creating voids that can weaken the weld.
-
Undesirable Groove in Weld Face: Typically referred to as "weld sink," this term is used to describe a groove or depression on the surface of the weld that is visually and structurally undesirable.
-
Reinforcement Identification: Excessive weld reinforcement, or weld overbuild, can lead to issues in fatigue strength and may require additional grinding or machining for proper profile.
