Abstract
A method for the orbital welding of tubular elements held in abutment comprising the steps of striking an arc at a strike point with an orbital welder between an electrode and a seam formed by a first tubular element and a second tubular element, held in abutment within a fixture; initiating an orbit of said electrode around an abutment of said first tubular element and said second tubular element; adjusting the current of said arc in a pulsed manner from a maximum current to a minimum current at a set frequency, combination of said maximum current and said minimum current forming an average current; decreasing said average current in a generally continuous manner as said orbit of said electrode progresses from said strike point, the rate of decrease of said maximum current having a generally inverse relationship to the rate of increase in temperature experienced by said tubular elements.
