QUALIFICATION TEST HAS NOT BEEN TAKEN WITHIN THE PAST 12 MONTHS.

SUBMIT AS EVIDENCE OF CONFORMANCE ALL RECORDS SHOWING PERIODS OF

EMPLOYMENT, NAME OF EMPLOYER WHERE WELDER, OR WELDING OPERATOR,

WAS LAST EMPLOYED, AND THE PROCESS FOR WHICH QUALIFIED.

4. A TACKER WHO PASSES THE QUALIFICATION TEST IS CONSIDERED ELIGIBLE

TO PERFORM TACK WELDING INDEFINITELY IN THE POSITIONS AND WITH

THE PROCESSES FOR WHICH HE IS QUALIFIED, UNLESS THERE IS SOME

OTHER THAN WELD LOCATIONS. EACH TEMPORARY WELD SHALL BE

REMOVED AND GROUND FLUSH WITH ADJACENT SURFACES AFTER

SERVING ITS PURPOSE.

THE PERMANENT WORK SHALL BE SUBJECT TO THE SAME QUALITY

REQUIREMENTS AS THE PERMANENT WELDS AND SHALL BE CLEANED

AND THOROUGHLY FUSED WITH PERMANENT WELDS. PREHEATING

SHALL BE PERFORMED AS SPECIFIED ABOVE FOR TEMPORARY WELDS.

MULTIPLE-PASS TACK WELDS SHALL HAVE CASCADED ENDS.

DEFECTIVE TACK WELDS SHALL BE REMOVED BEFORE

PERMANENT WELDING.

A. SUBMIT WRITTEN RECORDS TO INDICATE THE LOCATION OF WELDS

MADE BY EACH WELDER, WELDING OPERATOR, OR TACKER.

OPERATOR, OR TACKER WITH AN ASSIGNED NUMBER, LETTER, OR

SYMBOL TO IDENTIFY WELDS MADE BY THAT INDIVIDUAL. THE

CONTRACTING OFFICER MAY REQUIRE WELDERS, WELDING OPERATORS,

AND TACKERS TO APPLY THEIR SYMBOL NEXT TO THE WELD BY MEANS

OF RUBBER STAMP, FELT-TIPPED MARKER WITH WATERPROOF INK, OR

OTHER METHODS THAT DO NOT CAUSE AN INDENTATION IN THE METAL.

WELD AT 3 FOOT INTERVALS. IDENTIFICATION WITH DIE STAMPS OR

ELECTRIC ETCHERS IS NOT ALLOWED.

TESTS. WHEN MATERIALS OR WORKMANSHIP DO NOT CONFORM TO THE SPECIFICATION

TECHNICAL CONSULTANT; OR IF APPROVED, THE CONTRACTOR’S INSPECTION AND

TESTING PERSONNEL MAY BE USED INSTEAD OF THE COMMERCIAL INSPECTION OR

TESTING LABORATORY OR TECHNICAL CONSULTANT.

WELDS SHALL BE CLEANED AND CAREFULLY EXAMINED FOR INSUFFICIENT THROAT

OR LEG SIZES, CRACKS, UNDERCUTTING, OVERLAP, EXCESSIVE CONVEXITY OR

REINFORCEMENT AND OTHER SURFACE DEFECTS TO ENSURE COMPLIANCE WITH THE

THE CONTRACT DRAWINGS TO DETERMINE CONFORMANCE WITH PARAGRAPH STANDARDS

DETAILS OF WELDS, AND QUALITY OF WELDS WITH THE APPLICABLE REQUIREMENTS

TESTS PERFORMED BY THE CONTRACTOR FOR QUALITY CONTROL, THE GOVERNMENT MAY

PERFORM INSPECTION AND TESTING FOR ACCEPTANCE TO THE EXTENT DETERMINED BY

THE CONTRACTING OFFICER. THE COSTS OF SUCH INSPECTION AND TESTING WILL BE

GOVERNMENT IF THE WELDS ARE SATISFACTORY. THE WORK MAY BE PERFORMED BY THE

TESTING. THE GOVERNMENT RESERVES THE RIGHT TO PERFORM SUPPLEMENTAL

STANDARDS OF ACCEPTANCE.

IN THE WELD JOINTS, REPAIR DEFECTIVE WELDS USING A QUALIFIED WELDER OR

WELDING OPERATOR AS APPLICABLE. CONDUCT CORRECTIONS IN ACCORDANCE WITH

AWS D1.1 AND THE PROVISIONS OF THESE REQUIREMENTS. REPAIR ALL DEFECTS

AND REPAIR BY WELDING IS NOT REQUIRED, BLEND THE AFFECTED AREA INTO THE

SURROUNDING SURFACE TO ELIMINATE SHARP NOTCHES, CREVICES, OR CORNERS. AFTER

REPAIRED WELDS SHALL MEET THE INSPECTION REQUIREMENTS FOR THE ORIGINAL

Analysis Method: EPA SW846 7000B

The HUD lead guidelines for lead paint chips are 0.50% by Weight, 5000 ppm, or 1.0 mg/cm². The Reporting Limit (RL) for samples prepared by ASTM E-1979-12 is 10.0 ug Total Pb. The RL for samples prepared by EPA SW846 3050B is 25.0 ug Total Pb. Paint chip area and results are calculated based on area measurements determined by the client. All internal quality control requirements associated with this batch were met, unless otherwise noted.

LEGEND Pb= lead ug = microgram ppm = parts per million ug/g = micrograms per gram Wt. = weight

Reviewed By Authorized Signatory:

Preparation Method: ASTM E-1979-12
