I'm not sure if I have the terminology right, but this is more or less what my company's weld acceptance criteria is:
"When joining into a weld crater left by a previous weld, 70% (minimum) of the previous crater shall be overlapped."
Aside from being totally subjective, what do others use as a minimum of overlapping the crater? I'm trying to come up with a better measuring stick. Any comments would be appreciated.

js55 - You are absolutely correct. If the un-overlapped area is "higher", then it is mechanically acceptable. You can therefore possibly have none of the crater filled and still be good. Structurally it may cause stress risers and cosmetically it looks like crap.
jwright650 - Changing the requirement for full fill was my first thought, but lots of people are telling me that snags are going to skyrocket. We might just have to bite the bullet for the short term untill everyone learns to fill 100%.
I was wondering what other industries (pressure vessel, nuclear, defense, etc) use as a requirement.
