[MW:3568] Re: acceptance crerteria of undercut

one classic rule of thumb,use your fingernail to feel the undercut.If it over the limit specified below(i.e unacceptable), you would feel the undercut.If not the fingernail(i.e undercut is in the acceptable range) will glide over the undercut smoothly.
 
Thanks

Whats the wall tickness???
 
For criteria class C, check if h ≤0,1 t but max 0,5 mm...
If weld length is appr 100mm a 25mm discontinuity is allowed as per section 3.3 (EN ISO 5817)
