On a soldered wire, it would be due to solder creep.

In a proper connection, the heat rise is only a few degrees more than that produced in the conductor itself. If there is an excessive differential between the heat in a conductor, and the heat generated at a connection node, then the connection either has a problem, or is not of a sufficient capacity for the current in the circuit.

No, it does not. High frequency AC current moves the travel toward the surface, but low frequency AC and DC does not.
Where are you getting this crap? Skin depth at 60Hz is huge.
You are trying to get too deep into a mechanical structure here.
The term "blob" also has little technical depth. The tinning action of a metal by tin lead solder is called "wetting". The "blob" you refer to would be called a "dry solder joint" where the wetting action failed to take place. Still a rather inappropriate term to use here.
Wetting itself is the result of the action of the solder flux. It de-oxidizes the metals on the surfaces involved, and allows the molten solder to make a cohesive "inter-metallic" bond with them. The wetting action then works by the physical mechanism known as "capillary attraction". The surface tension of the molten solder alloy gives the final solder joint its shape. Any REAL soldering personage can tell by the appearance of this finished solder joint whether or not it was done properly. The REAL soldering inspector can tell at a mere glance.
So, even the use of the term "coating" in the topic header is incorrect. It leans toward the description of a failed solder joint. A good solder joint has an integrated appearance.

Technical specifications ARE understood, HAVE been laid out, and ARE NO LONGER open to negotiation after they have been set forth. AT least not by some lame inspector.
That IS the interpretation. Trying to mute them while in the position of an inspector is one of the most retarded behaviors in the industry, and shows said inspector to be of less understanding than his position dictates. In other words, he was promoted beyond his level of competency.
Very people oriented... how nice. The same is NOT true for scientific and technical specifications.
Try to pull that bullshit in the pharmaceutical industry or the chemical industry.. you won't have a job for a very long time.
Shame the same doesn't hold true in electronics. There would be a better understanding among pros and lay persons if it were.
Why is it legal to make U-turns in some states, but not others? Politicians are basically very lame when it comes to actually knowing about the technical aspects of what they are in control of.
No shit. Especially with all these mosh pit, pants down past their ass, uneducated punks we have in the world today.

There is a big difference between words that surround the laws and actions of people, and the words, laws, and technical specifications of a scientific standard.
I'm not an inspector, I see your point about regs, this is a wire, it melts at xx degrees etc. don't use it with an electrolytic connection etc.
It was a totally relevant cross posting, why you didn't reply with what you said earlier is beyond me, it'd maybe educate any wannaba lawyers in there some.
Anyway if I carry on like this I'll be more of a hypocrite than I laready am.
... : : Otherwise, you aren't any better than anyone else, and particularly : not any better than anyone you deride here.
Well, I dunno 'bout that: if you're included, then he's certainly better than you, that's a given. Fuchsy is a closed mind with a large bowel, I'm afraid. Nuff said
