Post Weld Cleaning of Aluminium
Post Weld Cleaning of Aluminium
(OP)
Hi Guys,
I am sure this is a simple question for those in the know.
I am doing a one off job that requires mig welding of aluminium. The welding is fine but I want to clean them up, but mostly the black soot like surface that surrounds them.
I know I can wire brush it with a hand stainless steel brush.
I have found an ultra fine (0.003" wire) wire brush for the bench grinder and that seems to work well.
What are some smarter options for cleaning? Is there a solution I make up to dip them in?
This is aluminium extrusion and is 32x32 angle, 3mm thick, welded into 500mm squares.
Thanks for being such a helpful community.
Regards, Iain.

If you need a brightening solution I would look to Alumi-Brite product. If you have to use this type product use all the recommended precautions as most contain Hydrofluoric Acid.
