Rust Prevention

What welding projects are you working on? Are you proud of something you built?
How about posting some pics so other welders can get some ideas?

Rust Prevention

Postby Rafe » Sat Jun 03, 2017 11:02 am

Hi. I am new to this site and not quite sure what part of the forum I should post this question. Thought I would try here first.

I am making some decorative boxes out of 16 gauge mild steel about 24" x 24" x 6". Often times they have to sit in my shop
for some time before they go to there powder coater. Here in hot and humid Georgia they almost immediately begin to rust.
Just looking for temporary solution that is easy and easy to clean up before they go for finishing. Thanks

You ca wipe them down after welding with a light oil, Kroil or Marvel Myster Oil work well. The powder coater will undoubtedly blast them clean anyway. Even the light flash rusting won't be an issue for him. You could also dip them in Metal Rescue to help treat them or for prolonged storage, Penetrol Flood works well.

A spray of inox is pretty good, dries and leaves a protective film that lasts a while.

I had the same problem with not only materials but any unplated tools and shop fixtures during hot, humid spells. The solution was to keep the shop closed up as much as possible and install a de-humidifier. Fasten a pleated furnace filter ( not the cheapo spun fiberglass crap) of Merv 6 or higher over the inlet side of the unit and set for 50% humidity and problem solved. Keep a humidistat in the shop to monitor levels and you will soon see how to keep it under control and you will be more comfy too. :D :geek:

Save the trouble with spraying and cleaning and get some Zerust bags, or any other brand with VCI 2000 on the inside. Will protect a long time as long as the bag is closed and the metal is dry when you put them in.

Hell, non-stick cooking spray will protect the parts for cheap. An acetone wipe or two will clean it right off.

Steve, Didn't you use camphor for this purpose?

I did not. I did share this idea from a friend. It was his trick for keeping his tools from rusting at a shipyard.

If you search camphor it does mention among other things to inhibit rust. Mabey those boxes could be put in big garbage bags with some camphor or as I do in storage boxes kitty litter in a sock . Perhaps a bag of rice might also work? I usually build bigger things - trailers etc. hence the dehumidifier for the whole shop. :idea: :geek:
