Ok, so my brew stand will be my first welding project. Practicing on a bunch of scrap material, and seem to be getting better at laying down a decent bead and getting decent penetration. I keep seeing stuff about how you should bevel the edges that you are welding for a cleaner lower weld bead. Do I really need to grind a bevel on every edge of the tubing that I am welding? Is it more of an asthetics thing than anything? I haven't tried it yet in my practicing, just curious what everyone's thoughts are.
