摘要
P the present invention relates to an arc welding process of the blades on the ring or on the counter - ring of the rotors of a rotary machine. / p & & p & the welding of the blades 2 is made from the outside through the ring in which are milled of the grooves blind, 3. The first strap 4 is executed with the aid of a tungsten electrode 5 without a coating of filler metal and in an inert atmosphere 6. The subsequent passes of filler are executed by the same process but with a filler metal. The method eliminates the requirements of a minimum height required for the welding by the inside and it gives the weld beads robust and a better surface quality. / p & & p & the present invention is particularly applicable to the rotating machines for the delivery of the fluids. / p
