Welding and hard surface deposition method of the metal parts made of aluminum by MIG method using a pulsed current and the filler wire .

摘要

The present invention provides a method for hard surface deposition of aluminum metal components of the turbine engine using a MIG welding apparatus including a pulse current generator and pulse filler metal wire feed , the hard surface adhesion , the composition is hard is realized by using a filler metal wire made ??of the same nature and composition of the aluminum alloy of the part that receives the surface adhesion , the pulse metal wire feed and deposition rate of the metal components of the turbine engine , to effect adhesion without high temperature cracking is characterized in that it is adapted to a method for . .
