how the repair was made?

HELLO TO ALL,
a few weeks ago, a bucket truck going east bound on
hyw 40, in st. louis county. the boom came loose, and
struck a bridge, and it punctured two beams. of course
the repair was made by welding, but it would be interesting
to see exactly how the repair was made. was a patch welded
over the hole, was a patch flush welded in the hole. i guess we
will never know, unless MODOT made a video of the repair.

more than likely the damaged area was cut out with a torch. then the cut ends were preped with a bevel. Next a new section of beam was cut to fit and spliced with a full pen weld and ultrasonically inspected.

[wlbrown]

are you saying a flush patch? i think this would be
stronger than just a patch welded over the hole.
anyway i sent MODOT a question, and ask them if
they knew how it was repaired, and if a video was
made. just curious.

It sounds like there was damage to a horizontal beam. If so, the damaged area will be removed and a new section fit and welded.

If it was MODOT probably bondo

I work for Canada's second largest bridge manufacturer...

I would say that the beam was ultrasounded and inspected for cracks, any cracks would be gouged, and any split or punctured area's would be removed and a new peice of bridge plate would have been welded in place. if something had to be removed, 100% pen. welds would be required and ALL repairs would be made with 8018 unless otherwise specified. Not sure what the codes are in the area? and then Q/A'd again with ultrasound.

One day, I was merging into freeway traffic as the overpass beam weldors were just pulling away from an over-height damage, patch job. Their l-o-n-g leads were unreeling onto the road. I blew my horn to get their attention, and they flipped me off! Neither of us stopped.

So yes, if it was that crew, the following day; they could have used bondo!
