Abstract

본 발명은 전기발열용가재(電氣發熱鎔加材)를 이용한 전기용접방법에 관한 것이다. 종래 용접의 경우 용접 부위를 이동하면서 용접하는 방법이므로 용접시간이 과다 소요될뿐 아니라 용접변형, 열부식, 가스, 화염, 악취, 불똥 등이 파생되어 작업환경이 열악하고 환경위해 요인이 있다. 또한 산화방지용 용접플럭스를 사용해야 되며 용접상태와 내력이 불균일하며 사용수명이 짧고, 별도의 마무리가공이 필요한 등의 문제점이 있다.The present invention relates to an electric welding method using an electric heating crawfish (電氣 發熱 鎔 加 材). Conventional welding is a method of welding while moving the welding site, not only takes excessive welding time, but also deforms welding, heat corrosion, gas, flame, odor, sparks, etc., resulting in poor working environment and environmental hazards. In addition, there is a problem that the welding flux for preventing oxidation should be used, the welding state and the strength are uneven, the service life is short, and a separate finishing process is required.

본 발명은 전기발열체(2)에 의해 융해되는 전기발열용가재를 모재(6)(12) 사이의 용접부에 위치시킨 다음 용접전원(14)이 인가되는 전극(13)(15)으로 가압하면 용가재(4)(10)가 용해되면서 용접모재(6)(12)가 용착되게 하므로서 용접개소가 다수이거나 용접평면적이 넓더라도 동시에 신속히 용접할 수 있게 하여 상기의 종래 문제점들이 일소되게 한 것이다.The present invention is located in the welding portion between the base material (6) 12 by melting the electric heating material is melted by the electric heating element (2) and then pressurized by the electrode 13, 15 to which the welding power source 14 is applied to the filler material ( 4) (10) is melted so that the welding base materials 6 and 12 are welded so that the welding problems can be quickly welded at the same time even if there are a large number of welding spots or a large welding plane area.
