Hoje em dia, os m\u00e9todos de soldagem de tubos soldados de a\u00e7o inoxid\u00e1vel usados na ind\u00fastria incluem principalmente soldagem a arco de arg\u00f4nio, soldagem de alta frequ\u00eancia, soldagem combinada.<\/h2>\n\n\n\n

Esses tr\u00eas m\u00e9todos de soldagem t\u00eam caracter\u00edsticas pr\u00f3prias. Atualmente, os mais comumente usados s\u00e3o a soldagem a arco de arg\u00f4nio e a soldagem de alta frequ\u00eancia. A seguir, apresentaremos os tr\u00eas tipos de tecnologias de processo de soldagem em detalhes.<\/p>\n\n\n

Soldagem de arco de arg\u00f4nio<\/strong><\/p>\n\n\n\n

Tubos soldados de a\u00e7o inoxid\u00e1vel<\/a> requerem penetra\u00e7\u00e3o profunda, n\u00e3o cont\u00eam inclus\u00f5es de \u00f3xido, a zona afetada pelo calor \u00e9 a menor poss\u00edvel e a soldagem a arco de tungst\u00eanio com g\u00e1s inerte de tungst\u00eanio tem boa adaptabilidade, alta qualidade de soldagem e bom desempenho de penetra\u00e7\u00e3o. \u00c9 amplamente utilizado nas ind\u00fastrias qu\u00edmica, nuclear e aliment\u00edcia.<\/p>\n\n\n\n

A baixa velocidade de soldagem \u00e9 a desvantagem da soldagem a arco de arg\u00f4nio. A fim de aumentar a velocidade de soldagem, a soldagem a arco de arg\u00f4nio com uma tocha de soldagem de tr\u00eas eletrodos \u00e9 geralmente usada. A espessura da parede do tubo de a\u00e7o soldado \u00e9 S \u2265 2 mm. A velocidade de soldagem \u00e9 3-4 vezes maior do que a de uma \u00fanica tocha de soldagem, e a qualidade da soldagem tamb\u00e9m \u00e9 melhorada. A combina\u00e7\u00e3o de soldagem a arco de arg\u00f4nio e soldagem de plasma pode soldar tubos de a\u00e7o de maior espessura. Al\u00e9m disso, hidrog\u00eanio 5-10% em arg\u00f4nio e, em seguida, usando energia de soldagem de pulso de alta frequ\u00eancia, tamb\u00e9m pode melhorar a velocidade de soldagem.<\/p>\n\n\n\n

Soldagem de alta frequ\u00eancia<\/strong><\/p>\n\n\n\n

A soldagem por frequ\u00eancia tem uma pot\u00eancia maior do que a fonte de alimenta\u00e7\u00e3o e pode atingir velocidades de soldagem mais altas para tubos de a\u00e7o de diferentes materiais e espessuras de parede externa. Em compara\u00e7\u00e3o com a soldagem a arco de arg\u00f4nio, \u00e9 mais de 10 vezes sua velocidade m\u00e1xima de soldagem. Portanto, a produ\u00e7\u00e3o de tubos de a\u00e7o inoxid\u00e1vel para uso geral apresenta maior produtividade.<\/p>\n\n\n\n

A alta velocidade da soldagem de alta frequ\u00eancia, que dificulta a remo\u00e7\u00e3o da rebarba na tubo de a\u00e7o inoxid\u00e1vel<\/a>. Atualmente, a soldagem de alta frequ\u00eancia de tubos de a\u00e7o inoxid\u00e1vel ainda n\u00e3o \u00e9 aceita pelas ind\u00fastrias qu\u00edmica e nuclear. <\/p>\n\n\n\n

Do ponto de vista dos materiais de soldagem, a soldagem de alta frequ\u00eancia pode soldar v\u00e1rios tipos de tubos de a\u00e7o inoxid\u00e1vel austen\u00edtico. O desenvolvimento de novos tipos de a\u00e7o e avan\u00e7os nos m\u00e9todos de conforma\u00e7\u00e3o e soldagem tamb\u00e9m soldaram com sucesso os tipos de a\u00e7o, como o a\u00e7o inoxid\u00e1vel ferr\u00edtico AISI 409.<\/p>\n\n\n\n

Soldagem combinada<\/strong><\/p>\n\n\n\n

Os m\u00e9todos de soldagem combinados s\u00e3o: soldagem a arco de arg\u00f4nio mais soldagem de plasma, soldagem de alta frequ\u00eancia mais soldagem de plasma, pr\u00e9-aquecimento de alta frequ\u00eancia mais soldagem a arco de arg\u00f4nio de tr\u00eas tochas, pr\u00e9-aquecimento de alta frequ\u00eancia mais soldagem de plasma mais arg\u00f4nio.<\/p>\n\n\n\n

A soldagem combinada melhora significativamente a velocidade de soldagem. Para tubos de a\u00e7o soldados combinados de pr\u00e9-aquecimento de alta frequ\u00eancia, a qualidade das costuras de soldagem \u00e9 equivalente \u00e0 da soldagem a arco de arg\u00f4nio convencional e da soldagem de plasma, e a opera\u00e7\u00e3o de soldagem \u00e9 simples. Todo o sistema de soldagem \u00e9 f\u00e1cil de automatizar. Baixo custo e bons benef\u00edcios.<\/p>\n\n\n\n

Em suma, cada m\u00e9todo de soldagem tem suas pr\u00f3prias vantagens e desvantagens. <\/p>\n\n\n\n

Combinar m\u00e9todos de soldagem para formar um novo processo de soldagem que atenda \u00e0s exig\u00eancias das pessoas \u00e9 uma nova tend\u00eancia no atual desenvolvimento da tecnologia de tubos soldados de a\u00e7o inoxid\u00e1vel.<\/p>\n\n\n\n
