Arc shielding is accomplished by covering the electrode tip, arc, and molten weld pool with a blanket of gas or flux, or both, which inhibit exposure of the weld metal to air.
A flux is a substance used to prevent the formation of oxides and other unwanted contaminants, or to dissolve them and facilitate removal.
The quantity of heat required to melt a given volume of metal does not depend on______
The power source in a particular welding setup generates 4000 W that can be transferred to the work surface with a heat transfer factor = 0.9. The metal to be welded is low carbon steel, whose melting temperature, is 1800 K. The melting factor in the operation is 0.6.
