The present invention relates to a cable for argon gas welding, which is used to be installed between a welding land and a welding main body during argon gas welding, and more particularly, to a structure of a pre-registered argon gas welding cable (registration number: 10-0973115). The outer circumferential surface of the gas conduit through which argon gas is discharged is covered with a braided part having excellent tensile strength and tightening force, and the control line is spirally installed between them, and separated from the high frequency induction line installed inside the gas conduit. The present invention relates to a cable for argon gas welding, which improves safety by increasing safety and durability of the control line and preventing short circuit or short circuit of the control line by installing the control line and the high frequency induction line.

일반적으로 아르곤가스 용접은 아르곤가스를 용접부위에 분사함과 동시에 용접모재와 용접토치에 설치된 전극봉과의 사이에 고주파를 유도함으로써 용접봉을 용해시켜 용접모재를 용접하는 방식이다.In general, argon gas welding is a method of welding a welding base material by dissolving the welding rod by inducing high frequency between the welding base material and the electrode installed in the welding torch while injecting the argon gas to the welding part.

이러한 아르곤가스 용접에 사용되는 아르곤가스는 고온에서 안정한 비활성 가스이므로, 용접부위에 공기를 차단하여 산화물의 발생과 불순물의 혼입으로 방지함으로써 정밀하고 세밀한 용접이 가능하여 탄소강이나 합금강이나 유색금속 등을 용접할 때 주로 많이 사용된다.The argon gas used for argon gas welding is an inert gas that is stable at high temperatures. Therefore, it is possible to precisely and finely weld by blocking the air at the welding part and preventing the generation of oxides and the incorporation of impurities to weld carbon steel, alloy steel or colored metal. When used a lot.

이와 같이 된 본 발명의 아르곤가스 용접용 케이블(100)은 아르곤가스 용접시 아르곤가스를 가스도관(2)을 통해 용접부위로 분사시키고, 이와 동시에 용접봉과 용접모재 사이에 높은 고주파 전류를 흘리는 고주파유도선(3)을 내설하여 용접기본체로부터 용접토치(1)로 공급하기 위한 것으로, 본 발명은 가스도관(2)의 외주면에 인장강도와 조임력이 우수한 다수층의 편조부(5)를 피복하고,의 이 내부에 고주파유도선(3)을 설치하며, 다수층의 편조부(5)로 감싼 외면에는 제어선(4)을 삽입하여 이를 고주파유도선(3)과 분리 설치하여 고무커버(6)로 감싼 구조로 이루어져 있으므로 장기간 사용하더라도 케이블(100)의 내부에 설치된 제어선(4)이나 고주파유도선(3)이 단선 또는 합선되는 것을 방지할 수 있으므로 케이블을 안정성과 내구성을 높임으로써 용접작업을 보다 안전하게 할 수 있음은 물론 용이하게 하고, 또사용수명을 높인 것에 특징이 있다. The argon gas welding cable 100 of the present invention as described above is a high frequency induction wire for injecting argon gas to the welding portion through the gas conduit (2) during the argon gas welding, and at the same time flowing a high frequency current between the electrode and the welding base material (3) is built in and supplied from the welding body to the welding torch (1), the present invention is to cover the braiding portion (5) of multiple layers excellent in tensile strength and tightening force on the outer peripheral surface of the gas conduit (2), The inside of the high frequency induction wire (3) is installed, and the control line (4) is inserted into the outer surface of the braided portion (5) of a plurality of layers and separated from the high frequency induction wire (3) by a rubber cover (6) Since it is made of a wrapped structure, even if it is used for a long time, the control line 4 or the high frequency induction line 3 installed inside the cable 100 can be prevented from being disconnected or short-circuited. Yes, of course it can more safely and easily has, again characterized by increased service life.

즉, 도 1 내지 도 3에 도시된 바와 같이, 편조부(5)를 다수층으로 감은 가스도관(2)의 내부에 고주파유도선(3)을 내설하고 제어선(4)을 가스도관(2)의 외주면을 따라 나선형으로 감아 설치한 다음, 고무커버(6)로 감싸 보호한 구조로 이루어져 있으므로 장기간 사용하여도 제어선(4)의 피복이 벗겨져 고주파유도선(3)과 합선 또는 단선되는 현상을 방지할 수 있고, 특히 제어선(4)이 단선됨으로써 발생하는 용접토치(1)의 동작불량을 방지하여 용접작업을 보다 용이하게 함은 물론 용접작업시 발생할 수 있는 안전사고를 예방하며, 이로 인해 용접용 케이블(100)을 장기간 안정적으로 사용할 수 있게 한 것이다.That is, as shown in FIGS. 1 to 3, a high frequency induction line 3 is installed inside the gas conduit 2 in which the braiding unit 5 is wound in multiple layers, and the control line 4 is connected to the gas conduit 2. Spiral wound along the outer circumferential surface of the wire) and then wrapped with a rubber cover (6) to protect it. Therefore, even if it is used for a long time, the cover of the control line 4 may be peeled off and short-circuit or short-circuit with the high frequency induction wire 3 may occur. To prevent the malfunction of the welding torch (1) caused by disconnection of the control line (4), thereby making the welding work easier and of course preventing the safety accidents that may occur during the welding work. Due to this, the welding cable 100 can be used stably for a long time.

또한, 본 발명은 가스도관(2)내에 제어선(4)을 고주파유도선(3)과 함께 설치한 종래의 아르곤가스 용접용 케이블(100)과는 달리, 가스도관(2) 내에 고주파유도선(3)을 내설하고 이의 외주면에 제어선(4)을 설치하여 고주파유도선(3)과 분리 배치함으로써 보다 안정적으로 케이블(100)을 구성함으로써 이의 내구성을 향상시켜 장기간 안정적으로 사용할 수 있도록 하였다.Further, the present invention is different from the conventional argon gas welding cable 100 in which the control line 4 is installed together with the high frequency induction line 3 in the gas conduit 2, and the high frequency induction line in the gas conduit 2 is provided. (3) was installed and the control line 4 was installed on the outer circumferential surface thereof so as to be separated from the high frequency induction line 3 so as to construct the cable 100 more stably, thereby improving its durability so that it can be used stably for a long time.

이에 따라, 본 발명은 케이블(100)을 보다 안정적으로 보호하게 됨으로써 용접작업을 보다 용이하게 할 수 있게 함은 물론 장기간 사용하더라도 제어선(4)이나 고주파유도선(3)이 단선 또는 합선되는 것을 방지할 수 있으며, 또 케이블(100)이 안정적으로 고정됨으로써 용접토치(1)를 자유자재로 다룰 수가 있으므로 용접작업을 보다 용이하게 할 수 있으므로 용접품질을 높일 수 있는 장점이 있다.As a result, the present invention provides a more stable protection of the cable 100, thereby making it easier to weld, as well as the fact that the control line 4 or the high frequency induction line 3 are disconnected or short-circuited even after long-term use. Since the cable 100 is stably fixed, the welding torch 1 can be freely handled, and thus the welding work can be more easily performed, thereby improving the welding quality.

여기서, 편조부(5)는 가스도관(2)의 외주면에 다수층으로 감싸고 있고, 또 제어선(4)은 가스도관(2)의 외주면을 따라 나선형으로 감은 구조로 이루어져 있으므로 케이블(100)을 쉽게 구부릴 수 있어 이의 이동성과 유동성을 향상시키게 됨으로써 종래의 케이블(100) 구조에 비해 용접토치(1)를 더욱 자유자재로 다룰 수 있으므로 용접작업을 보다 정밀하게 할 수 있게 되며, 이로 인해 용접품질을 더욱 향상시킬 수 있게 된다.Here, the braiding portion 5 is wrapped in a plurality of layers on the outer circumferential surface of the gas conduit 2, and the control line 4 is formed in a spiral wound along the outer circumferential surface of the gas conduit 2, so that the cable 100 Since it can be easily bent to improve its mobility and fluidity, the welding torch 1 can be handled more freely than the conventional cable 100 structure, and thus the welding work can be made more precise. It can be further improved.

즉, 용접작업 중에 케이블의 반복적인 구부러짐이나 뒤틀림이 있더라도 제어선과 고주파유도선이 반복적인 응력을 받음으로써 케이블의 취부에서 발생하는 마찰에 의해 단선이 발생하게 되는데, 이때 편조부(5)와 제어선(4)은 연성과 인장강도가 우수한 재질로 이루어져 있으므로 반복적인 응력을 받더라도 쉽게 단선되는 것을 피할 수 있고, 특히 신축성이 낮은 폴리에스터사 또는 나일론 등과 같은 합성섬유사를 편조하여 이루어지게 되면 용접작업 중에 내부의 고주파유도선(3)과 제어선(4)이 쉽게 신축되지 않으므로 반복적인 응력을 받더라도 단선의 발생을 막을 수 있으므로 케이블(100)의 안정성과 내구성을 높여 용접작업을 보다 안전하게 할 수 있음은 물론 용이하게 할 수 있게 된다.That is, even if the cable is repeatedly bent or twisted during the welding operation, the control wire and the high frequency induction wire are subjected to repeated stresses, thereby causing disconnection due to friction generated in the cable mounting. (4) is made of a material with excellent ductility and tensile strength, so it can be easily avoided disconnection even under repeated stress, and especially when braided by synthetic fiber yarn such as polyester yarn or nylon with low elasticity, Since the internal high frequency induction wire 3 and the control line 4 are not easily stretched, it is possible to prevent the occurrence of disconnection even under repeated stresses, thereby increasing the stability and durability of the cable 100, thereby making the welding work safer. Of course it can be done easily.

이와 같이 본 발명은 케이블(100)을 장기간 사용하더라도 내설된 제어선(4)이나 고주파유도선(3)이 단선 또는 합선이나 단선되는 것을 방지할 수 있으므로 케이블(100)의 안정성을 높여 용접작업을 보다 용이하게 하는 효과가 있으며, 특히 용접케이블(100)의 내구성을 향상시킴으로써 사용수명을 높여 장기간 안정적으로 사용할 수 있는 효과가 있다. As such, the present invention can prevent the built-in control line 4 or the high frequency induction line 3 from disconnection, short-circuit or disconnection even if the cable 100 is used for a long time, thereby increasing the stability of the cable 100 and performing welding work. There is an effect that makes it easier, in particular by improving the durability of the welding cable 100 has the effect of increasing the service life can be used stably for a long time.
