Abstract
A method and apparatus is disclosed for feeding welding flux to both the leading and trailing sides of the strip electrode used in a submerged arc strip cladding process. In order to prevent distortion of the bead shape the pressure due to the weight of the flux burden is controlled to be less in the region of the molten metal and slag pools lying directly behind the welding arc. The flux burden is caused to increase from a first depth directly behind the strip to a maximum depth at the trailing edge of the weld crater region where the quantity of liquid metal and liquid slag is a minimum.
