Adequate feedability is essential for GMAW processes to ensure efficiency. The feedability of a wire refers to the wire’s ability to feed continuously through the contact tip. While there are several known causes of feedability difficulties when using cored welding wires, there are many variables that have yet to be explored thoroughly. Three factors are investigated in this research to determine their effects on feedability of cored wires: fill percentage, baking time, and baking temperature. A set of metal-cored arc welding wires were created with various fill percentages, baking times, and baking temperatures. Tension testing, microhardness testing, microstructural characterization, and feedability testing were performed on all wires. The tension testing and microhardness testing showed that the baking cycles do slightly affect these properties for the wires. The feedability testing did not show any significant differences amongst the wires dependent upon the fill percentage or baking conditions.
