Abstract

[목적][purpose]

용접부위에서 전혀 오목 자국이 발생되지 않게 할 수 있는 새로운 무흔 스포트 용접 방법과 이를 구현하는 장치를 제공함.The present invention provides a new incandescent spot welding method capable of preventing concave marks from being generated on a welded portion and a device for implementing the same.

[구성][Configuration]

가동 전극 팁을 관통하는 도전 통로의 임의 위치 단면적을 급격히 축소시켜서 상기한 가동 전극 팁의 선단부에서 고전류 밀도 영역이 발현되게 하고, 이것에 의해 피용접물 사이의 접촉부 저항으로 발생되는 발열량을 증대시켜 오목 자국이 형성되지 않게 하고자, 가동 전극 팁의 바디 외주면에 절연체를 끼워 붙여 상기한 가동 전극 팁의 내부에 형성되는 도전 통로가 임의 위치에서 단면적이 급격히 축소되게 하고 있다.The cross sectional area of the conductive path passing through the movable electrode tip is sharply reduced so that the high current density region is developed at the tip end of the movable electrode tip to thereby increase the amount of heat generated by the contact resistance between the workpieces, The insulator is sandwiched between the outer circumferential surface of the body of the movable electrode tip so that the sectional area of the conductive path formed inside the movable electrode tip is sharply reduced at an arbitrary position.
