Everything you wanted to know about how soldiers and not dared to ask

Abstract

Some time ago, a year or so, I realized something that puzzled me: Many of my classmates do not know career welds in components or connectors. By the way, I study or at least try as long as I make clear, Telecommunications Engineering. The event described is normal. No one has taught and of course by "infused knowledge" do not learn anything (at least I have not seen).
