I wanted to start a different thread specific to this question. I went down and bought a bunch of box steel and a flat plate and I am building a welding table. Now I do not expect it to look like a store bought powder coated device but I want it to look nice and stay together...and not look like something I built. I have a MIG welder and I am going to try to learn how to weld whilst building a table So the question is...How does one (me) prepare mill steel for welding and painting? I can just take the grinder with the sanding wheel and sand down the edges that I am going to weld so as to get the weld to not splatter however after it is all welded up the mill scale will still be on the pieces and I want the paint to stick so I guess I need to clean off the mill scale??? From my other thread I took the cut up pieces of box steel and used a foam brush to smear on some muriatic acid on the outside of the steel and also used an acid wetted scotch bright pad to "polish" down the mill scale and the surface rust, then hosed off the parts and then took some baking soda and water in a bucket and placed the parts into the bucket for a couple of minutes...pulled them out, hosed them off and now they look clean with just a little bit of flash rust. When it is all welded up I want to scotch bright polish the bare metal and then spray with rattle can primer and paint. What brand of rattle can paint will work best? Thanks everyone for your well wishes, moments of silence, positive energy, and welding/painting dances to help me get this project done...oh and of course the advice is also appreciated!!!
