Title
(KO) 스폿 용접용의 협착 노즐이 있는 TIG 용접 토치 및 이것에 사용되는 전극용 노즐
Abstract
(KO) 본 발명은, 초보자이여도 기술습득을 간단하게 할 수 있어서 양호한 스폿 용접을 행할 수 있는 동시에, 작업성의 향상, 용접 품질의 향상, 생산성의 향상 등을 꾀할 수 있다. 본 발명은 실드 가스를 통과시키는 토치 바디(2)와, 토치 바디(2)에 삽착되고 음극에 접속되는 텅스텐 전극봉(5)과, 텅스텐 전극봉(5)의 선단부를 동심 형상으로 지지하고, 텅스텐 전극봉(5)과의 사이에 실드 가스(G)가 흐르는 가스 통로(6e)를 형성함과 아울러, 가스 통로(6e)로부터 분출되는 실드 가스(G)를 토치 바디(2)의 선단으로부터 분출되는 실드 가스(G)보다 고속으로 분출시키는 협착 노즐(6)과, 협착 노즐(6)의 외주에 텅스텐 전극봉(5)과 동심 형상으로 배치되고, 선단부가 끝이 좁아지는 형상으로 형성되어서 끝이 좁아지는 형상의 선단이 텅스텐 전극봉(5)의 선단보다 바깥쪽에 위치함과 아울러, 어스케이블(18)을 개재해서 양극에 접속되는 도전성을 갖는 통 형상의 전극용 노즐(7)을 구비하고, 상기 전극용 노즐(7)에 실드 가스(G)의 가스 배출구(7c, 7d)를 형성으로 한다.
