In one company where I worked, we measured a foot of weld four times per shift. We recorded the numnber of defects occurring in the sample. We had 24 possible defects. Thus, if porosity and undercut we observed, we had 2 defects.
By the way, this was my “famous” projects. Derfects were reduced from an average of 1.47 per foot to 0.05. The department returned $3 million (USD) of their labor budget to the company in the first year.
I hope this helps you.
