Abstract

"PROCESSO E INSTALAçãO DE SOLDAGEM LASER COM MISTURA GASOSA Ar/He COM TEORES CONTROLADOS EM FUNçãO DA POTêNCIA LASER". Processo de instalação de soldagem por feixe laser, utilizando uma mistura gasosa de proteção, contendo argónio e hélio, no qual a proporção de argónio e/ou de hélio nessa mistura gasosa é escolhida ou ajustada em função da potência ou da densidade de potência desse feixe laser. A potência laser está compreendida entre 0.5 kW e 30 kW, de preferência entre 5kW e 20 kW. A mistura gasosa de proteção é constituída de argónio e/ou de hélio, de preferência a mistura gasosa contém uma proporção volumétrica de hélio de 30 a 80%, o resto sendo argónio e, eventualmente, impurezas inevitáveis.
