Hi, for a college project I need to be able to stick weld 3mm x 20mm x 20mm mild steel angle,this will be mostly at 90 and 45 degree butt joints. However although new to welding I am not sure what size rod I whould be using, or the gap between the angle pieces in my joint for maximum weld penetration/strength.
Therefore I would appriciate any advice in this field
Thanks
Ollie
