With O/A-welding, that's sometimes right. Only when I was trained at, we
had a kind of grating. just several upright flat irons, distanced about
1" apart and welded in a frame.
Looks like your first project? :-)

Later, I never needed something like this.

One of the handiest things to have, is a chunk of walkway grid.
mounted on legs. My first welding table was this

It worked well for years, and I could cut directly on the table.
I still use it as a cutting table even though I now have a 4x8 steel
topped welding table.
