RE: Tack Welds

Are these welds actually tack welds or a line of stitch welding? The 
distinction is paramount. If they're actually tack welds, they were made 
to maintain alignment prior to final permanent welding. Stitch welds 
(more correctly intermittent welds) are final permanent load-bearing 

An intermittent weld detail will be called out on a drawing--tack welds 
won't be. If all you have is tack welds, it's convincing evidence that 
someone failed to make the final welds or that someone else forgot to 
detail the connections. Hard to imagine that someone went to the trouble 
of designing a lateral bracing system without at least hinting around at 
the connections.
