What is the differentiating factor between flux core arc welding and gas-shielded metal arc welding processes? Correct Answer structure and chemical composition of electrode

The structure and chemical composition of electrode wire is the differentiating factor between flux core arc welding and gas-shielded metal arc welding processes. Unlike gas-shielded metal arc welding, flux core arc welding electrode wire is not solid and consists of thin-walled metal tube filled with flux.
