RE: Ugly welds
For example, weld spatter does NOT affect strength, but weld spatter on a handrail affects function (it hurts and cuts hands using the handrail!) so it is unacceptable.
If the product cannot be sold, loses sales because of looks or appearance or function (bad paint adherence or inability to add powder coating successfully due to holes and overlap) and "lumpiness" then - YES - "ugly matters" ....

Accept/reject decisions must be made on the criteria provided by th applicable welding standard.

RE: Ugly welds
Keep in mind that the definition of a 'Gorilla weld' is big, fat, ugly and strong. Very few ugly welds are weak; however most ugly welds fail to meet D1.1 profile requirements. And maybe 1/4th of the welders producing ugly stuff will fail an on-demand welding test. If you are the Inspector-of-Record, CWI or not, you have the right to demand that a welder retest "right now, right here" if his/her work is suspect. Not proven to be all bad, just reasonably suspect.

In the American Welding Society Online Forum, for a reason that I can not explain, it is not possible to open the files shown in the thread http://www.aws.org/cgi-bin/mwf/topic_show.pl?tid=3....
I am posting a dropbox link containing the photos that originally were depicted in that thread. Pay attention to the billboard that is supported by these welds.

Don't leave dangerous garbage like this unrepaired. It's a ballpark!

Thanks again gtaw, for sharing this code with us ( http://eng-tips.com/viewthread.cfm?qid=359518 )
RE: Ugly welds
The welds shown were definitely "ugly", and were substandard by any definition. The welds obviously lacked proper surface preparation, and were contaminated by surface corrosion and paint. The welds also lacked sufficient penetration and fusion at the joints, and exhibited significant amounts of gas porosity.
Anyone familiar with welding processes knows when a weld looks right and when it doesn't.
