Strange-Looking Weld Phenomenon - Can You Identify This?
Strange-Looking Weld Phenomenon - Can You Identify This?
(OP)
In doing a brief visual inspection of some steel floor framing erected over ten years ago, I came upon this rather strange-looking "material" at the location of a rather hack field weld.
Bearing in mind that this location experiences frequent high ambient relative humidity owing to exposure to the outside air (and in an area that is quite humid a good deal of the time), can you help me identify what this is, and what has caused it? In particular I want to satisfy myself that it is not detrimental.
FWIW, I have an idea what I'm looking at but I'd rather get some additional opinions.
