Capillary electric welding process to repair au00c7os carbon, high, average and low alloy, in condiu00c7u00e7o of tempered or nu00e7o; au00c7os Hadfield; cast iron; nickel and its alloys; metallic coatings and uniu00d5es dissimilar to produce appropriate microstructure in welded uniu00e7o Without need of heat treatment pu00e0s - welding.This is a process of electric welding capillary for the repair of carbon steel of high, medium and low alloy, under the condition of tempered or not hadlield; STEELS; cast iron; nickel and its alloys; metal coatings and dissimilar joints.To produce the appropriate microstructure in the welded without heat treatment after welding, including, initially, the preparation of the metalbase for welding through the generation of appropriate grooves (7), followed by the use of a coated electrode fenu00edtico - austenu00ed Tico to produce layers of welding.Where the first layer (1) is used to coat the surface of the grooves (7) and the father to execlitar pass from the root; the second layer (2) allows the deposit of fillets of solder microstructure and the mechanical properties suitable for the application of equipment; in the third and fifth layers (3, 5) A coated electrode Ferritic Austenitic is used to compose layer.But a fillet welding of the electrode austenhhico can be used between the fillets of solder deposits ferritic - Austenitic, but always beginning and ending with a deposit of ferritic - austenitic electrode (AF) on both sides of the groove; the fourth layer (4) is similar to the second cam ADA, however,The welding with an electrode on the microstructure and mechanical properties superior to those of an electrode used in the second layer; and the sixth layer (6) is similar to the second layer, however, using an electrode on the microstructure and mechanical properties superior to those of the electrode Used in the fourth layer.
