BOC 4047 aluminium welding rods.datadavid said:Now is where you put up the link to the gas filler rods. Pure aluminium? No... useless mechanical properties, too soft.
If you use flux you are soldering.
Halo=HAZ
I use aluminium with either 5% Mg or 5% Si when welding with the tig - too soft? I think not..
Flux stops oxidation in the weld. When I stick weld I use rods encased in flux, as everyone else does - fairly sure that's not soldering.
And Halo=HAZ, sorry, I have no idea what that means.
