I had to have the aluminum bed frame in our Class A rewelded, it had broken welds in several places. Looks like it had just been spot-welded at the factory, I could have done better with super glue and epoxy. Took the frame to a local company that manufacturers heavy equipment and got it all rewelded. Some of the prettiest welds you have ever seen, each was a masterpiece, and will never break again. the welds looked more like a bead from a calking gun that from a hand welder. So there are still a lot of good welders around, ones that take pride in dooing a good job.
