A method of welding, comprising: creating a weld puddle (P, 601A, 603A, 901, 903, 1012, 1022), in at least one workpiece (115, W1, W2), with at least one high intensity energy source; characterized in determining an operational voltage range to maintain the voltage above a minimum amount, ensuring a high enough current to maintain the filler wire (140, 1030, 1030A) at or near its melting temperature, but below a voltage level such that no welding arc is created, heating at least one filler wire (140, 1030, 1030A) with a filler wire heating signal from a power source to a temperature such that said filler wire (140, 1030, 1030A) melts in said weld puddle (P, 601A, 603A, 901, 903, 1012, 1022); directing said filler wire (140, 1030, 1030A) to said weld puddle (P, 601A, 603A, 901, 903, 1012, 1022) such that said filler wire (140, 1030, 1030A) maintains contact with said weld puddle (P, 601A, 603A, 901, 903, 1012, 1022) during a welding operation; maintaining said filler wire (140, 1030, 1030A) heating signal at a level below an upper threshold level such that no arc is created between said weld puddle (P, 601A, 603A, 901, 903, 1012, 1022) and said filler wire (140, 1030, 1030A), wherein, no shielding is employed during the welding operation, shutting off said filler wire (140, 1030, 1030A) heating signal when said upper threshold value is reached by said filler wire (140, 1030, 1030A) heating signal such that no arc is generated between said filler wire (140, 1030, 1030A) and said weld puddle (P, 601A, 603A, 901, 903, 1012, 1022); and turning on said filler wire (140, 1030, 1030A) heating signal to continue heating said filler wire (140, 1030, 1030A). creating a weld puddle (P, 601A, 603A, 901, 903, 1012, 1022), in at least one workpiece (115, W1, W2), with at least one high intensity energy source; characterized in determining an operational voltage range to maintain the voltage above a minimum amount, ensuring a high enough current to maintain the filler wire (140, 1030, 1030A) at or near its melting temperature, but below a voltage level such that no welding arc is created, heating at least one filler wire (140, 1030, 1030A) with a filler wire heating signal from a power source to a temperature such that said filler wire (140, 1030, 1030A) melts in said weld puddle (P, 601A, 603A, 901, 903, 1012, 1022); directing said filler wire (140, 1030, 1030A) to said weld puddle (P, 601A, 603A, 901, 903, 1012, 1022) such that said filler wire (140, 1030, 1030A) maintains contact with said weld puddle (P, 601A, 603A, 901, 903, 1012, 1022) during a welding operation; maintaining said filler wire (140, 1030, 1030A) heating signal at a level below an upper threshold level such that no arc is created between said weld puddle (P, 601A, 603A, 901, 903, 1012, 1022) and said filler wire (140, 1030, 1030A), wherein, no shielding is employed during the welding operation, shutting off said filler wire (140, 1030, 1030A) heating signal when said upper threshold value is reached by said filler wire (140, 1030, 1030A) heating signal such that no arc is generated between said filler wire (140, 1030, 1030A) and said weld puddle (P, 601A, 603A, 901, 903, 1012, 1022); and turning on said filler wire (140, 1030, 1030A) heating signal to continue heating said filler wire (140, 1030, 1030A).
