Abstract

"método para construção de um pistão" um método de soldagem por fricção de um pistão inclui formar um corpo de pistão por soldagem por fricção de um porção de coroa superior para uma porção de coroa inferior. pelo menos uma das porções de coroa superior e inferior é provida com uma coluna de suporte central estendendo-se ao longo de um eixo central. as porções de coroa superior e inferior têm nervuras anulares radialmente para o exterior a partir da coluna de suporte central, com as nervuras sendo alinhadas entre si. o método inclui iniciar uma junta de solda por fricção entre uma extremidade livre da coluna de suporte central e uma correspondente superfície oposta à extremidade livre da coluna de suporte central. então, depois de iniciar a junta de solda entre a coluna de suporte central e a superfície oposta, o método continua por então inicia uma junta de solda por ficção entre as extremidades livres alinhadas das nervuras. então, as juntas de solda por fricção são concluídas.
