Re: [MW:23818] Welders Qualification Filletwelds.

According to ASME IX:

 

 

QW-303 LIMITS OF QUALIFIED POSITIONS AND DIAMETERS (SEE QW-461)

QW-303.1 Groove Welds — General. Welders and welding operators who pass the required tests for groove welds in the test positions of Table QW-461.9 shall be qua­lified for the positions of groove welds and fillet welds shown in Table QW-461.9. In addition, welders and weld­ing operators who pass the required tests for groove welds shall also be qualified to make fillet welds in all thicknesses and pipe diameters of any size within the lim­its of the welding variables of QW-350 or QW-360, as applicable.

QW-303.2 Fillet Welds — General. Welders and welding operators who pass the required tests for fillet welds in the test positions of Table QW-461.9 shall be qua­lified for the positions of fillet welds shown in Table QW-461.9. Welders and welding operators who pass the tests for fillet welds shall be qualified to make fillet welds only in the thicknesses of material, sizes of fillet welds, and diameters of pipe and tube 2⁷/8 in. (73 mm) O.D. and over, as shown in Table QW-452.5, within the applicable essential variables. Welders and welding opera­tors who make fillet welds on pipe or tube less than 2⁷/8 in. (73 mm) O.D. must pass the pipe fillet weld test per Table QW-452.4 or the required mechanical tests in

QW-304 and QW-305 as applicable.

Goodmorning.

To qualify a welder who's weld a filletweld, you have to take 1 macroetch and 1 fracture test.

The question is : When it is not possible to break the fracture test or when the fracture test doesn't breaks, what is the possibility (according ASME IX) to qualify the welder.?
