Hello everyone,
I am currently building an aluminium catamaran out of 5083 and 6060, 6082. I tacked one of the hulls together and paid somebody to come in and do the majority of welding for me (so it doesn’t fall apart on its maiden voyage) and now I have to begin the arduous task of taking all the tops off the welds on the outside of the hull (Approximately 120 metres per hull). I tried many different grinding discs, flap discs, sanding discs that claimed they were for aluminium and obviously they all clogged up with aluminium so I’m just wondering what everybody recommends I should use to do it? I’ve heard of waxes and everything but I’m worried about buying the wrong one and using it one day to pre grind for a weld I might have to do and having that weld fail at a later date? Or just any other ideas on a quick way to remove the tops? I have a 4” and 5” electric grinder plus a 4” pneumatic grinder set up as well.
I should also point out that it doesn’t have to be neat yet, I just need to get it flush for now and then I rough the whole thing up later with 36grit for the paint to bond to
I’m also in Australia just in case that matters!
Thank you all in advance, Tom
