Effects of Some Process Parameters on Weld Bead: A Brief Investigation
Subscribe/Renew Journal
With the recent advancements in welding processes in industries, it has become increasingly necessary to develop suitable work parameters corresponding to the work material and process. This experimental work deals with the characterization of some parameters to obtain a desired weld bead by using a mixture of argon and carbon dioxide in a ratio of 3:1 at a much higher gas flow rate than used traditionally. Three uniform, partially penetrating, single pass beads are made on 25mm thick E250 semi-killed carbon alloy steel flats. The experimental results are then used to calculate the heat input during each pass to study the effect of net heat input on bead geometry. Finally the desired process parameters are evaluated to adopt.
