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. |
