Abstract

PROCESSO E SISTEMA SEM GáS PARA SOLDAGEM CIRCUNFERENCIAL EM APLICAçõES DE ALTA RESISTêNCIA. A presente invenção refere-se a um sistema e método de soldagem para a soldagem circunferencial de materiais de alta resistência com o uso de um processo de soldagem a arco voltaico e de um eletrodo de auto-blindagem. O sistema de soldagem contém um aparelho de soldagem que avança o eletrodo de auto-blindagem na direção de uma obra a ser soldada e controla o comprimento do arco e a operação do aparelho, de modo que a solda satisfaça as exigências para soldar pelo menos tubos de Grau X-80 do Instituto de Petróleo Americano, O sistema adicionalmente contém uma fonte de energia com um controlador para criar um pulso de corrente que introduz energia no eletrodo para fundir a extremidade do eletrodo de auto-blindagem e uma seção de transferência de metal quiescente de baixa corrente depois do final do pulso de fusão durante o qual o eletrodo fundido entra em curto-circuito contra a obra.
