Description

용접 방법welding method

본 발명은 용접방법에 관한 것으로서, 더 상세하게는 두 모재를 저항열을 이용하여 용융접합시키는 용접방법에 관한 것이다.The present invention relates to a welding method, and more particularly, to a welding method in which two base materials are melt-bonded using resistance heat.

저항열을 이용한 용접법의 하나로서, 일반적으로 스폿 용접(spot welding)법이 널리 사용되고있다. 이 스폿 용접은, 모재와 전극과의 접촉 저항열에 의해 두 모재가 용융 결합되는 용접 방식을 말한다. 즉, 모재의 상하 부위를 전극으로 통전시키면서 가압하여, 접촉된 모재면에서 발생되는 저항열에 의하여 피용접물을 용융 결합시키도록 되어있다.As one of welding methods using resistance heat, spot welding is widely used. This spot welding refers to a welding method in which two base materials are melt-bonded by heat of contact resistance between a base material and an electrode. That is, the upper and lower portions of the base material are pressed while energizing the electrode, and the welded object is melt-bonded by the heat of resistance generated on the contact surface of the base material.

도 1은 이와 같은 종래의 스폿 용접법에 사용되는 용접장치를 나타낸다. 도면을 참조하면, 고정대(101) 위에 전원공급부(102)가 장착되고, 그 고정대(101)에 하부 전극(103) 및 하부 홀더(104)가 고정 설치되며, 상기 전원공급부(102)의 상부에는 상부 전극(105) 및 상부 홀더(106)가 이동가능하게 결합되어 있다.1 shows a welding apparatus used in such a conventional spot welding method. Referring to the drawings, the power supply unit 102 is mounted on the fixing base 101, the lower electrode 103 and the lower holder 104 is fixed to the fixing base 101, the upper portion of the power supply unit 102 The upper electrode 105 and the upper holder 106 are movably coupled.

이와 같은 구조에 있어서 용접작업을 수행할 때에는, 먼저 피용접물(107)을 상기 상,하부전극(105,103) 사이에 위치시킨 다음, 상기 상부전극(105)을 전진시켜 그 피용접물(107)을 상,하부전극(105,103)으로 파지한 후, 전류를 통전시키면서 가압하게 된다.In this structure, when the welding operation is performed, the welded object 107 is first positioned between the upper and lower electrodes 105 and 103, and then the upper electrode 105 is advanced to raise the welded object 107. After being gripped by the lower electrodes 105 and 103, pressure is applied while energizing the current.

그런데 이와 같은 용접방법에 있어서는, 도 2에 도시된 바와 같이 피용접물(107a,107b)의 한 부위(A)를 상,하부전극(105,103)으로 용접시킨 후, 다시 다음 용접부위(B)로 전극(105,103)을 이동시켜 용접 작업을 수행하게 되므로, 작업시간이 많이 소요되는 문제점이 있다.In this welding method, however, as shown in FIG. 2, one part A of the welded object 107a and 107b is welded to the upper and lower electrodes 105 and 103, and then the electrode is welded to the next welding part B again. Since the welding operation is performed by moving the 105 and 103, there is a problem that takes a lot of work time.

본 발명은 상기의 문제점을 해결하기 위해 창출된 것으로서, 용접 작업 시간을 단축시킬수 있는 용접 방법을 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems, and an object thereof is to provide a welding method that can shorten the welding work time.
