THE CITY OF SUNNY ISLES BEACH <br />PROJECT NO. 21-1011 <br />BUILDING DEPARTMENT RELOCATION TO ANNEX <br /> <br />Project No. 21-1011 November 2024 051400-7 <br /> <br /> <br />E. Full penetration groove welds shall be [ultrasonic] [radiographic] tested by a qualified <br />technician who will operate the equipment, record any defects found and their <br />disposition. The technician will be under the supervision of a Level II or III ASNT <br />technician. Repair and re-test defective welds at no additional cost to the University. <br />F. Initially, 100percent of the welds which require [ultrasonic] [radiographic] testing shall <br />be tested to establish the qualifications of each individual welder. If the reject rate of a <br />welder's work is demonstrated to be less than 5 percent of the tested welds, then the <br />frequency of testing may be reduced to 25 percent. If the reject rate of a welder's work <br />increases to 5 percent or more, 100 percent shall be re-established until the rate is <br />reduced to less than 5 percent. The percentage of rejection shall be calculated and <br />recorded for each welder. The body of data used to calculate the reject rate shall <br />contain at least 40 tests. The reject rate is defined as the number of rejected welds <br />divided by the number of welds completed multiplied by 100. For evaluating the reject <br />rate of continuous welds over [3 feet] [0.9 m] long, each [12 inch] [305 mm] increment <br />one inch or less thick, shall be considered one weld and each [6 inch] [152 mm] <br />increment over one inch thick, shall be considered one weld. <br /> <br />G. When base metal thicker than [1-1/2 inches] [38 mm] is subjected to through-thickness <br />weld shrinkage strains, the welds shall be 100 percent [ultrasonically] [radiographically] <br />tested for discontinuities after completion of the joint. <br />END OF SECTION <br />
