  1. COMPORTAMIENTO MECANICO DE LOS MATERIALES Trabajo Práctico Nº 6 SOLDADURA HETEROGENEA

  2. Brazing de dos tubos de acero tipo SAE 1020 solapados Material de aporte: 25% Ag, Cu, Zn y Cd Falta de penetración Adherencia correcta Trabajo práctico Nº6 soldadura heterogénea Estructura de ferrita y perlita de los metales base Rechupe en el metal de aporte

  3. Trabajo práctico Nº6 soldadura heterogénea Brazing de Banjo y tubo de acero de bajo %C. Material de aporte: latón ( Cu-Zn) Material de aporte Banjo Material de aporte Tubo Buena penetración del metal de aporte

  4. Soldadura de acero SAE 1020 y tubo de cobre. Material de aporte: aleación de Cu + Zn + 1% de Ag. Metal de aporte acero aporte Poro cobre Trabajo práctico Nº6 soldadura heterogénea acero acero aporte aporte

  5. Brazing (soldadura fuerte) de un tubo de alta presión. Bundywelld® Material base: acero SAE 1005. Material de aporte: cobre Tubo según corte longitudinal y transversal Aporte de cobre acero Trabajo práctico Nº6 soldadura heterogénea Buena adherencia (sin discontinuidad) Aporte difundido en algunos espacios intergranulares

  6. REVESTIMIENTO

  7. ANALYSIS OF THE SERVICE CONDITIONS TO DETERMINE THE TYPE OF WEAR AND • ENVIRONMENTAL RESISTANCE REQUIRED • SELECTION OF SEVERAL HARDFACING ALLOY CANDIDATES • ANALYSIS OF THE COMPATIBILITY OF THE HARDFACING ALLOYS WITH THE BASE • METAL, TAKING INTO CONSIDERATION THERMAL STRESSES AND POSSIBLE CRACKING • FIELD TESTING OF HARDFACED PARTS • SELECTION OF AN OPTIMUM HARDFACING ALLOY, CONSIDERING COST AND WEAR • LIFE • SELECTION OF THE HARDFACING PROCESS FOR PRODUCTION OF WEAR COMPONENTS, • CONSIDERING DEPOSITION RATES, THE AMOUNT OF DILUTION, DEPOSITION, • EFFICIENCY, AND OVERALL COST, INCLUDING THE COST OF CONSUMABLES AND • PROCESSING

  8. EFFECT OF DILUTION ON THE MICROSTRUCTURE OF A FE-28CR-4MO-0.4MN-4.6C HARDFACING ALLOY. (A) FIRST LAYER OVER MILD STEEL SHOWING A HYPOEUTECTIC STRUCTURE OF METAL DENDRITES AND INTERDENDRITIC EUTECTIC, 55 HRC. (B) SECOND LAYER SHOWING A FINE HYPOEUTECTIC STRUCTURE WITH A LARGE PERCENTAGE OF EUTECTIC MATRIX, 57 HRC. (C) THIRD LAYER SHOWING A COARSE HYPEREUTECTIC STRUCTURE OF PRIMARY M7C3 CARBIDES IN A EUTECTIC MATRIX, 61 HRC. (D) FIFTH LAYER SHOWING A STRUCTURE SIMILAR TO BOTH THE THIRD AND FOURTH PASSES, 60 HRC.
