To reduce the residual stress and improve the toe blend angle weld Toe
can be smoothen and fillet welds should be convex and use a 3:1
minimum taper for the thickness transition and blend grind the weld
cap flush to remove any local stress concentration.
In general weld is acceptable Max. 3mm depth of profile measured from
the top of the face plate to the top of the weld
If the minimum reinforcement not mentioned, weld flushing up to plate
level is acceptable and more over it depends on drawing or specific
code

AWS D1.3 Acceptance Criteria
6.1 Production Weld Acceptance Criteria
6.1.1 Visual Inspection. A weld shall be acceptable by visual
inspection, provided all four of the following
criteria are met:
6.1.1.1 No Cracks. The weld shall have no cracks.
6.1.1.2
Minimum Reinforcement. The weld shall have minimum reinforcement of
1/32 in. (1mm)
for all square groove, arc spot, and arc seam welds.
6.1.1.3
Undercut. The cumulative length of undercut shall be no longer than L/
8, where L is the
specified length of the weld or in the case of arc spot welds, the
circumference, provided fusion
exists between the weld metal. Depth of undercut is not a subject of
inspection and need not be
measured. Melt-through that results in a hole is unacceptable.
6.1.1.4

convex.
