I use an assortment of screwdrivers to gradually open up the fold without creating a bunch of bent metal. You don't need to open it very much to make room to get the rusted out inner skin section out. You do need to open it up some in order to get all of the rust out after you remove the rusted out inner skin.
I do not think that there are any welds to deal with.
