Seems like I'm well on my way & progressing with my welding projects, shouldn't be too long before I have some pieces completed.
I am using painted SHS and some black flat bar. I will be painting everything when all the welding is done. I just wanted to check on the best methods to reach this end with a minimal of doubling up on prep work etc.
Obviously I'll need to get out the flap disc and remove the paint from the SHS wherever it's being welded. But I'm just wondering if it's "best practice" to then use a zinc primer (weld through) do there isn't a bare metal section in the hole where the other piece of SHS joins up (if that makes sense)?
Or would you just leave it bare, weld it, then go ahead painting just like normal?
These pieces are going to be used in a vehicle fitout, so I guess you can say it's an "interior" use. But there may be occasional moisture if it's raining outside etc. (bringing wet tools & equipment into the cabinets etc.) I just want to make sure I do it right so that everything lasts a very long time, definitely don't want to be dealing with rust problems down the track.
A question on the black steel - I'll be removing the black finish at the weld points, but I'm not sure if it's okay to paint over the black finish? I sure hope so, otherwise that's a heck of a lot of work... :-
Cheers for any tips! :2tsup:
