Angle “A” Degrees

Welders completing groove welds often end up with excessive face reinforcement on their welds. Whether they just want
to make sure the joint is filled in or they think it makes the weldment “stronger”, it typically causes more potential for harm
than good. Excessive face reinforcement on a groove weld will typically create a larger stress riser which may increase the
odds of the weldment cracking because of fatigue. Note the location of the crack in the weld image below.
Excessive Face Reinforcement
By increasing the reinforcement angle of the weld metal as
shown in these images, the maximum amount of stress the
assembly could withstand almost doubled.
Additionally, removal of the reinforcement can restore fatigue
performance to near un-welded condition in non heat-treatable
alloys or re-heat-treated surfaces.
