AWS D1.1 inspection

AWS D1.1 inspection

AWS D1.1 inspection

(OP)
need a little help with  of acceptance criteria for RT of butt welds , I have a 1" weld ,based on 6.12.1.1  (1) Table 6.1 allows  discontinuities can be up to .6875" in size; 6.12.1.1(2)  also limits spacing of discontinuities.example; If I have two indications 1/8" in lenght that are acceptable for size but too close together according to Table 6.1 C factor , the weld is rejected based on spacing of Discontinuities not thier size, . In other words can a indication thats acceptable for size  but fails the spacing requirments be cause for reject of  weld.  

RE: AWS D1.1 inspection

What welding standard/code are you referring to. If you are looking at AWS D1.1, Table 6.1 addresses visual acceptnce criteria, not RT criteria.

sorry should be fig 6.4  

RE: AWS D1.1 inspection

Yes.  As the requirement is if 'any' of the limitations is exceeded.  Therefore if your 1/8" discontinuities are spaced less than ~2/5" (~10 mm) per Figure 6.1 then it is a reject weld. (D1.1 2004/2008/2010)
