<div>Don’t know if it applies in this case, but sometimes a broken fastener is jammed against the end of a tapped hole. In that case just drilling through the fastener can break it loose. Using a left hand drill bit in this case will sometimes cause the stub
to catch the bit and spin out with no damage to the hole.</div>

<div class="PlainText">As Michael said, your best bet for the task you describe is a MIG<br>
welder. A gas torch will heat up a much larger area than you want,<br>
and it will take some time for the target piece to reach a temperature<br>
that is needed (meanwhile igniting surrounding combustibles). For an<br>
expert weldor, a TIG welder can produce miracles. But for the rest of<br>
us a MIG machine can do a lot. <br>
<br>
A gas MIG would be best but even a cheaper MIG that used flux core<br>
wire might get the jobs done. It would be cheaper.<br>
