Sin duda, el uso del aluminio est\u00e1 aumentando en la industria de la fabricaci\u00f3n de soldadura. Los fabricantes suelen adoptar este material, bien por innovaci\u00f3n, bien por la presi\u00f3n ejercida por sus usuarios finales. Recientemente han surgido algunos problemas de soldadura de aluminio durante la operaci\u00f3n (como se ve en la imagen).<\/p>\n

\"Aluminum<\/a><\/p>\n

Nos advierte que debemos prestar m\u00e1s atenci\u00f3n a la prevenci\u00f3n para el defecto de la soldadura de aluminio. Habr\u00e1 mostrar dos defectos principales de la soldadura de aluminio y la forma de evitar que los componentes de ellos de la siguiente manera.<\/p>\n

Porosidad: <\/strong>La porosidad es el resultado de que el gas hidr\u00f3geno quede atrapado en el aluminio solidificado durante la soldadura y deje huecos en la soldadura terminada. La porosidad puede dividirse en agujero denso, agujero de aguja, etc. El hidr\u00f3geno puede proceder de todos los aspectos de la zona de soldadura, como la humedad de la atm\u00f3sfera de la columna de arco, la humedad absorbida por el material de soldadura y la pel\u00edcula de oxidaci\u00f3n de la superficie del metal base. La porosidad tiene una gran influencia en el rendimiento de la soldadura. No s\u00f3lo reduce el trabajo efectivo de la secci\u00f3n transversal de la soldadura para degradar el rendimiento mec\u00e1nico de la soldadura, sino que tambi\u00e9n destruye la densidad de la uni\u00f3n soldada, para causar fugas f\u00e1cilmente. Debido a la formaci\u00f3n de concentraci\u00f3n de tensiones en el borde del agujero, el pl\u00e1stico de la junta de soldadura ser\u00e1 hacia abajo. Por lo tanto, para la soldadura importante, el agujero de aire debe ser estrictamente controlado. Hay algunas razones espec\u00edficas para las causas de la porosidad.<\/p>\n

    \n
  1. La pureza del gas arg\u00f3n es baja, demasiadas impurezas o tuber\u00edas de gas arg\u00f3n con agua y fugas en las tuber\u00edas de gas arg\u00f3n.<\/li>\n
  2. El alambre de soldadura o el metal base cerca de la soldadura de ranura no est\u00e1n limpios antes de soldar, o est\u00e1n contaminados con suciedad, humedad despu\u00e9s de la limpieza, etc.<\/li>\n
  3. Soldadura por arco de arg\u00f3n con protecci\u00f3n de gas arg\u00f3n no est\u00e1 calificado, la inestabilidad del arco, el arco es demasiado largo, electrodo de tungsteno extendido a trav\u00e9s de largo.<\/li>\n
  4. Selecci\u00f3n incorrecta de los par\u00e1metros de soldadura, velocidad de soldadura demasiado r\u00e1pida o demasiado lenta.<\/li>\n
  5. l entorno h\u00famedo, velocidad del viento elevada.<\/li>\n<\/ol>\n

    Por todo ello, existen algunas medidas preventivas.<\/p>\n

      \n
    1. Garantizar la pureza del gas protector.<\/li>\n
    2. Mantenga limpios el alambre de soldadura y la ranura del metal base.<\/li>\n
    3. Selecci\u00f3n correcta del par\u00e1metro de soldadura.<\/li>\n
    4. Precalentar antes de soldar.<\/li>\n
    5. Aseg\u00farese de que el entorno de trabajo est\u00e9 seco e instale el dispositivo cortavientos.<\/li>\n<\/ol>\n

      Rompiendo:<\/strong> Esta forma de agrietamiento en el aluminio suele estar causada por una combinaci\u00f3n de debilidades metal\u00fargicas del metal de soldadura a medida que se solidifica con la tensi\u00f3n transversal aplicada a trav\u00e9s de la soldadura. El agrietamiento es el defecto de soldadura m\u00e1s peligroso, afecta seriamente al rendimiento y la fiabilidad de seguridad de la estructura de soldadura, y tambi\u00e9n es una de las principales causas de muchos da\u00f1os en la estructura de soldadura. Existen razones espec\u00edficas.<\/p>","protected":false},"excerpt":{"rendered":"
