Flame straightening

[camdigger]

This is one of the best presentations I've seen on the how's and whys of flame straightening. Most interesting to me is a brief reference to applying it to Aluminum sheet metal

A few years ago, there was a collision with a steel framed overpass bridge near here. They brought in a specialized crew and straightened out most of the damage while only shutting down one lane of the 4 lane underneath and one on the 2 lane road on top. Took nearly a month, but they got it all done in situ.
