Hi all,
Its been a long time since I've been on the forums, nice to be back!
So my question has to do with metal storage.
We purchase our steel in large quantities for the whole academic year and we are located in a town near the the Pacific ocean....i.e rust accumulates in short order. After a few months every project involves a lot of grinding, sanding, or sandblasting in order to weld which besides being a kill joy to metalworking, adds time to our construction projects. No room to store steel inside. Has anyone successfully precoated steel with weldable primer for storage reasons? If so:
1. Can you MIG weld through the primer or do you end up grinding the weld site?
2. How long does the primer hold up to the elements?
3. If cleaning the primer off before welding is required, do you find the removal of primer to be easier/faster than removing rust?
4. Do you have a product recommendation and source?
Thanks!
