Started with 12" x 12 " x 16 GA square steel sheet in the first class.
We learnt basics of welding, cutting, grinding, glazing, polishing with steel surfaces.
The only thing that came to my mind with those 9 pieces of smaller 4" x 4" square sheets, was a small house-like structure :)
For welding : acetylene (5 psi) + Oxygen (5 psi)
For cutting: acetylene (5 psi) + Oxygen (25 psi)
