recommended rod for welding 3" thick steel

we have to build a box out of 3" thick steel but not sure what rod we should use, could you help? another thing is what kind of bevel should be done on the steel.


Probably the biggest diameter 7018 stick you can handle for the position.

If the welds can be done flat or horizontal, a 3/16" rod will put down a lot of metal.

bevels should be adequate to allow for complete penetration if that is what the print or application calls for .
usually around s 45-60 degree included angle.

if you are welding to a spec, like AWS D1.1, the joint specs can be located there.
