Does it matter if no one checks my weld?

You did not sign up to be a philosopher. You signed up to join metal to metal so it holds weight. But you have noticed something true: no inspector can watch every inch of every seam. What holds the beam up, in the end, is not the code book. It is you, alone, with the torch, when no one is looking. This matters more, not less, because you work with others. A crew is only as honest as its least careful hand. If you cut corners quietly, someone else inherits the risk without knowing it — the next welder, the engineer who trusts your mark, the person standing under the beam. Sloppy work hidden inside good-looking work is a kind of lie you tell your whole team without saying a word. So stop treating precision as a personality trait some people have and others don't. It is a decision, made fresh at every joint. You are not born careful. You choose it, weld by weld, in front of your crew or alone in the dark.
