If you are welding rebar that will hold a building up, you need Part 1. If you are welding rebar to hold the rebar in place during pouring (spacers), you need Part 2. —they reinforced the joints to meet the standard's
Before diving into the specifics of the PDF document, it is vital to understand the "why." Reinforced concrete relies on the tensile strength of steel and the compressive strength of concrete. When welds fail, structures fail. Before diving into the specifics of the PDF
