Abstract

"MéTODO PARA A MELHORIA DA PENETRAçãO DE SOLDAGEM EM SUPERFìCIE DE OXIDAçãO E ARTIGO". Um método para a soldagem das partes de montagem (12, 14) em liga superalloy a base de níquel ou a base de ferro em um artigo unitário. Inicialmente, as partes da montagem (12, 14) são aquecidas em uma atmosfera de ar, a uma taxa apropriada para minimizar as distorções geométricas, até uma temperatura na faixa de cerca de 760 <198>C (1400 <198>F) a cerca de 1090 <198>C (2000 <198>F) para formar uma camada de óxido (24) sobre as superfícies das partes (12, 14) e opcionalmente como um tratamento térmico de solução de pré soldagem. A temperatura das partes (12, 14) é mantida na faixa de cerca de 760 <198>C (1400 <198>F) a cerca de 1090 <198>C (2000 <198>F) por um tempo suficiente para formar uma camada de óxido (24) de espessura suficiente sobre a superfície das partes (12, 14) e opcionalmente para a solução das partes (12, 14). As partes (12, 14) são então resfriadas à temperatura ambiente a uma taxa suficiente para evitar a precipitação de fases metálicas não desejadas e a uma taxa suficiente para manter a estabilidade dimensional. A camada de óxido (24) é então removida de pelo menos uma das superfícies sobrepostas (16, 18) das partes, mas não das faces laterais (20, 22) das partes (12, 14). As partes (12, 14) são então soldadas, usando um procedimento de soldagem GTA, para formar um artigo unitário. O artigo é então resolvido a uma temperatura apropriada e por um período de tempo apropriado, sendo que ambos são dependentes do tipo das ligas superalloy que estão presentes no artigo soldado e das propriedades desejadas. O artigo é então opcionalmente ser submetidos a um tratamento térmico para eliminar as tensões internas (age), a uma temperatura apropriada e por um período de tempo apropriado, sendo que ambos são dependentes do tipo das ligas superalloy que estão presentes no artigo unitário soldado .
