Questions about dent removal in .080 5052 h-34 aluminum
My son and I are working on an older riveted aluminum boat . The boat is drilled apart at this point so we can upgrade the seam sealing with a better product. In the bottom pan there are several low shallow dents caused by the boat not being adjusted to the trailer by the former owner they are from the rollers and are 6-7 " long 3-4" wide and around 1/2 " deep there are no sharp creases. I read through Kents excellent information on his site about working under the anneal temperature to shrink these back. My questions are what temp should a person shoot for with this alloy and thickness .How many times can it be heated and what methods of straightening tools etc will leave the material in the best condition after the repair. It does not have to be perfect as there are many small dings and scuffs on the bottom. We will also be filling some old not used holes in a couple spots with tig so welding info for this alloy would be great as well Thanks Chris

Hi Chris, I know your problem and will set up a demo for you so you can see - 5052 is the hardest aluminum alloy to flame anneal because of the temp sensitivity - and you don't want to mess it up!!!!

Kent, are the 5xxx series aluminum more sensitive in general to anneal or is it a characteristic specific to 5052?
