This invention relates to a method and apparatus for controlling the composition of a weld. More particularly it relates to welding using an electric circuit, thereby creating a weld puddle, and adding at least one filler that is electrically independent from the electric circuit to the weld puddle at a controllable rate to obtain a target weld composition. The filler can be added to the extent limited by practical weld puddle geometry and, thus, the method and apparatus also facilitate increased weld deposition rates.

Controlled composition welding method

An apparatus for curing bonded welding flux wherein the flux is passed along a series of vibrating inclined planes. Gas fired radiant heaters are positioned above the planes to heat the flux, with combustion gases and vapor driven off the flux passing upwardly between the radiant heaters and the flux covered planes.
