So that folks won't have to go back and forth to see what I mean about OEM workmanship

Notice that the gouged (bent up and to the side) still has the weld bead but
the other half of that welded seam is straight.
It should have been melted by the MIG arc and fused with both the other half
and the MIG wire
If melted and fused, it should have torn and left a torn edge, not a straight
edge shown
Also, why the tear ended where it did...the welded bead above that
did do what it is supposed to do...melt and fuse the three (tow sheet
metal halves with the filler wire)
This is a common high rate production issue. The welds 'look' just fine, but
the bead did not 'stick', nor did it melt both sides
Not so common for TIG, as most use a manual filler rod feed along with a manual
torch. There are some automatic wire fed TIG, but mostly for smaller stuff. Like
some high end alu bicycles (not so much anymore now that plastic is the high end
bike material)
