Q.

What is the differentiating factor between flux core arc welding and gas-shielded metal arc welding processes?

A. structure and chemical composition of electrode
B. structure and chemical composition of metal plate
C. time of welding
D. process of welding
Answer» A. structure and chemical composition of electrode
Explanation: 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.
