  • Method for welding and for hard surface deposition of metal parts made of aluminium by a MIG method with pulsed current and filler wire
    Patent number: 9731373
    Abstract: A method for hard surface deposition on aluminum metal parts of a turbine engine using MIG welding equipment which includes a pulsed current generator and pulsed filler metal wire feed, wherein the deposition is achieved using a filler metal wire whose composition is of the same nature as the composition of the aluminum alloy of the part to undergo hard surface deposition, with the pulsed metal wire feed and speed of deposition on the metal part of the turbine engine being adapted to carry out deposition without hot fissuring.
    Type: Grant
