Significance of electrode stick-out when welding with flux-cored wires

Abstract

Electrode stick-out is a parameter which makes it possible to change welding energy without changing the quantity of deposited metal delivered to a welding puddle. It is particularly important when welding with flux-cored wires. Knowledge of its impact on welding parameters and formation of weld geometry is very useful when making fillet welds of small thicknesses. Understanding the mechanism of electrode stick-out's impact on weld geometry helps to avoid many problems when welding.
