Ej \u00e9 comumente chamado de \"coeficiente de junta de soldagem\", tamb\u00e9m conhecido como coeficiente de junta de soldagem. De fato, o coeficiente da junta de soldagem \u00e9 um conceito em produtos de vasos de press\u00e3o. Em vasos de press\u00e3o t\u00edpicos, as juntas de solda s\u00e3o geralmente classificadas em quatro categorias com base em sua posi\u00e7\u00e3o: A, B, C e D. Para simplificar, A representa a costura de solda longitudinal na carca\u00e7a e no cabe\u00e7ote, B representa a costura de solda de topo circunferencial na carca\u00e7a, C representa a costura de solda de topo circunferencial conectada ao flange e D representa a costura de solda entre o tubo de conex\u00e3o e a carca\u00e7a. Um diagrama esquem\u00e1tico t\u00edpico \u00e9 o seguinte:<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Os padr\u00f5es de classifica\u00e7\u00e3o e as instru\u00e7\u00f5es para juntas soldadas est\u00e3o detalhados na cl\u00e1usula 4.5.1 do GB150.1-2011 Pressure Vessels, enquanto a cl\u00e1usula 4.5.2 especifica o coeficiente das juntas soldadas. A primeira frase afirma claramente que \"o coeficiente das juntas soldadas deve ser determinado com base na forma da solda e na rela\u00e7\u00e3o do comprimento do teste n\u00e3o destrutivo da junta de topo\". A partir dessa frase, podemos ver que \"a forma da solda e a rela\u00e7\u00e3o do comprimento do teste n\u00e3o destrutivo da junta de topo\" determinam o \"coeficiente da junta de solda\", que \u00e9 uma rela\u00e7\u00e3o l\u00f3gica muito importante. Vamos dar uma olhada em como a ASME regulamenta o coeficiente de juntas soldadas. Na abertura da UW-12 no Volume 8, Parte 1 da ASME VIII. 1-2019 Rules for Construction of Pressure Vessels Division 1, tamb\u00e9m \u00e9 mencionado que \"a efici\u00eancia de uma junta depende apenas do tipo de junta e do contexto do exame da junta e n\u00e3o depende da extens\u00e3o do exame de qualquer outra junta\". A l\u00f3gica \u00e9 consistente com as disposi\u00e7\u00f5es da GB150.1.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

A fun\u00e7\u00e3o das juntas soldadas em estruturas \u00e9 determinada principalmente por sua posi\u00e7\u00e3o, e o estado de tens\u00e3o das soldas em diferentes posi\u00e7\u00f5es varia. Portanto, a posi\u00e7\u00e3o se torna o principal fator a ser considerado na fun\u00e7\u00e3o das juntas soldadas. O fato de uma junta soldada poder ou n\u00e3o desempenhar sua devida fun\u00e7\u00e3o \u00e9 determinado pela qualidade da junta soldada, e o processo de obten\u00e7\u00e3o da qualidade da soldagem ser\u00e1 influenciado por fatores cong\u00eanitos, como a \"dificuldade de implementa\u00e7\u00e3o do processo\". Ao mesmo tempo, tamb\u00e9m \u00e9 necess\u00e1rio considerar os fatores adquiridos de que \"os indicadores de qualidade contradizem os indicadores econ\u00f4micos\". Obviamente, tudo isso se baseia na seguran\u00e7a como o ponto principal. Portanto, no projeto estrutural, a ado\u00e7\u00e3o de diferentes coeficientes de junta de soldagem \u00e9 um resultado comum da integra\u00e7\u00e3o e do equil\u00edbrio de v\u00e1rios fatores e tem um significado pr\u00e1tico significativo.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Al\u00e9m disso, embora diferentes coeficientes de juntas de solda correspondam a diferentes propor\u00e7\u00f5es de teste na forma, eles correspondem fundamentalmente a diferentes n\u00edveis de qualidade. De modo geral, o n\u00edvel de qualifica\u00e7\u00e3o das soldas de teste n\u00e3o destrutivo 100% \u00e9 o n\u00edvel II, enquanto o n\u00edvel de qualifica\u00e7\u00e3o das soldas de teste n\u00e3o destrutivo 20% \u00e9 o n\u00edvel III. Diferentes n\u00edveis de qualifica\u00e7\u00e3o resultam em diferentes tamanhos e quantidades de defeitos permitidos.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>","protected":false},"featured_media":0,"template":"","categories":[],"tags":[],"class_list":["post-46913","blog","type-blog","status-publish","hentry"],"yoast_head":"\nWelding coefficient in the order -
