APPENDIX VIWELD PROFILE ACCEPTANCE DESCRIPTION(1) The faces of fillet welds may be slightly convex, flat, or slightly concave as shown in Appendix V (A) and (B),with none of the unacceptable profiles shown in (C). Except at outside corner joints, the convexity, C, of aweld or individual surface bead with dimension W shall not exceed the values noted in the table in Appendix V.(2) Groove welds shall preferably be made with slight or minimum reinforcement except as may be otherwiseprovided. In the case of butt and corner joints, the reinforcement shall not exceed 1/8 in [3.2 mm] in height andshall have gradual transition to the plane of the base metal surface. See Appendix V. They shall be free of thediscontinuities shown for butt joints in (E).(3) Surfaces of groove welds required to be flush shall be finished so as not to reduce the thickness of the thinnerbase metal or weld metal by more than 1/32 in [0.8 mm] or 5% of the thickness, whichever is smaller, nor leavereinforcement that exceeds 1/32 in [0.8 mm]. However, all reinforcement must be removed where the weldforms part of a faying or contact surface. Any reinforcement must blend smoothly into the plate surfaces withtransition areas free from weld undercut. Chipping may be used provided it is followed by grinding. Wheresurface finishing is required, its roughness value shall not exceed 250 µin [6.3 µm]. Surfaces finished to valuesof over 125 µin [3.2 µm] through 250 µin [6.3 µm] shall be finished so that the grinding marks are parallel tothe direction of primary stress. Surfaces finished to values of 125 µin [3.2 µm] or less may be finished in anydirection.(4) Ends of groove welds required to be flush shall be finished so as not to reduce the width beyond the detailedwidth or the actual width furnished, whichever is greater, by more than 1/8 in [3.2 mm] or so as not to leavereinforcement at each end that exceeds 1/8 in [3.2 mm]. Ends of welds in butt joints shall be faired to adjacentplate or shape edges at a slope not to exceed 1 in 10.(5) Welds shall be free from overlap.7

APPENDIX VIIVISUAL WELD INSPECTION ACCEPTANCE CRITERIASlag shall be removed from all completed welds. All welds and the adjacent base metal shall be cleaned by brushing or by any other suitable means prior to visual inspection. All welds shall meet the following visual acceptancecriteria prior to any nondestructive or destructive testing. To be visually acceptable, a weld shall meet the followingcriteria:(1) The weld shall have no cracks.(2) Thorough fusion shall exist between adjacent layers of weld metal and between weld metal and base metal.(3) All craters shall be filled to the full cross section of the weld.(4) Weld profiles shall be in accordance with Appendices V and VI.(5) When the weld is transverse to the primary tensile stress in the part that is undercut, the undercut shall be nomore than 0.010 in [0.25 mm] deep.(6) When the weld is parallel to the primary tensile stress in the part that is undercut, the undercut shall be nomore than 1/32 in [0.80 mm] deep.(7) The sum of the diameters of visible porosity shall not exceed 3/8 in [9.5 mm] in any linear inch of weld norshall the sum exceed 3/4 in [19.0 mm] in any 12 in [305 mm] length of weld.(8) Any single continuous fillet weld shall be permitted to underrun the nominal fillet weld size specified by1/16 in [1.6 mm].(9) Visual inspections of welds in all steels may begin immediately after the completed welds have cooled toambient temperature. Final visual inspection for ASTM A 514 and A 517 steel welds shall be performed notless than 48 hours after completion of the weld and removal of preheat.(10) Arc strikes outside the weld groove or area are prohibited.8

APPENDIX VIIITEST RESULTS REQUIRED, GUIDED BENDSAll Guided Bend Tests. The convex surface of the bend test specimen shall be visually examined for surface discontinuities. For acceptance, the surface shall meet the following criteria:(1) No single discontinuity shall exceed 1/8 in [3.2 mm] measured in any direction.(2) The sum of the greatest dimensions of all discontinuities exceeding 1/32 in [0.8 mm] but less than or equal to1/8 in [3.2 mm] shall not exceed 3/8 in [9.5 mm].(3) Corner cracks shall not exceed 1/4 in [6.4 mm] unless the crack results from a visible slag inclusion or otherfusion type discontinuity, then the 1/8 in [3.2 mm] maximum shall apply.The specimens with corner cracks exceeding 1/4 in [6.4 mm] with no evidence of slag inclusions or other fusiontype discontinuities shall be disregarded, and a replacement test specimen from the original weldment shall betested.9
