Tack welds are temporary fixtures used to hold pieces in position during fit-up. They’re small, attract short bead lengths, and are meant to keep alignment and gaps correct while the final welding is prepared. Because of that temporary role, they aren’t automatically part of the finished weld. In many cases they’re removed or ground away before the full weld is laid down, so the final joint isn’t influenced by those initial tiny welds. If the welding plan explicitly covers a tack weld with a continuous final weld that completely fuses it, then it can become part of the weld, but that isn’t guaranteed or assumed by default. That’s why the correct answer is that tack welds do not inherently become an integral part of the weld.
