본 고안은 전기아크용접기의 고주파 유도가열장치에 관한 것으로서, 더욱상세하게는 전기아크용접기를 사용하여 용접작업시 공급되는 용접용와이어 및 용가제인 필러메탈(Filler Metal)이 용접아크부로 송급되기 전에 유도가열 시킬수 있도록 한 것이다.The present invention relates to a high frequency induction heating apparatus of an electric arc welder, and more particularly, a welding wire and a filler metal (filler metal) supplied during a welding operation using an electric arc welder are induced before being fed to the welding arc part. It can be heated.

종래 전기 아크용접기중 가스메탄 아크용접기는 제1a에 나타낸 바와 같이, 용접전원부(13)의 +극출력이 와이어피더(14)로 연결되고, 와이어피더(14)와 연결된 토오치(1a)를 통하여 송급되는 용접용와이어(3)에 전원이 인가되어 용접용 와이어(3)와 모재(작업물)(15) 사이에 발생된 아크열로 상기 용접용와이어(3)와 모재(15)가 녹아서 용접되어 용접비드(Bead)를 형성하며 용접을 하게 되는데 이때, 아크열은 -극인 모재(15)에 30%, +극인 용접와이어(3)에 70% 정도가 공급된다.The gas methane arc welder of the conventional electric arc welder is connected to the wire feeder 14 with the + pole output of the welding power supply unit 13 as shown in 1a, and through the torch 1a connected with the wire feeder 14. The welding wire 3 and the base material 15 are melted by arc heat generated between the welding wire 3 and the base material (workpiece) 15 by supplying power to the supplied welding wire 3. The welding bead (Bead) to form a welding, in which the arc heat is supplied 30% to the base material (15-pole), the welding wire (3) is about 70%.

또한 가스텅스텐 아크용접기는 제1b도에 나타낸 바와 같이, 용접전원부(13)의 -극이 토오치(1b)에 연결되어 용접기의 출력은 토오치케이블(16)을 통해 상기 토오치(1b)끝단의 텅스텐 전극을 거쳐 +극이 연결된 모재(15)사이에 아크를 발생시켜서 용접을 하게 되는데 이때, 모재(15)의 경우에는 녹아서 얇어지거나, 구멍이 발생하게되므로 모재(15)와 같은 재질의 용가제인 필러메탈(16)을 용접아크부에 수동 또는 자동으로 공급하여 모재(15)가 얇아지거나 구멍이 생기는 것을 방지하게 된다.In addition, the gas tungsten arc welding machine, as shown in FIG. 1b, is connected to the torch 1b of the welding power supply unit 13 so that the output of the welding machine is connected to the torch 1b through the torch cable 16. An arc is generated between the base metals 15 connected to the + poles through a tungsten electrode of the electrode, and welding is performed. In this case, the base material 15 is melted and thinned, or a hole is generated. The zener filler metal 16 is supplied to the welding arc part manually or automatically to prevent the base material 15 from thinning or forming a hole.

그러나, 이와같은 종래의 전기아크용접기의 용접용 와이어(3)나 필러메탈(16)은 용접아크부에 도달하여 가열과 용융이 이루어지므로 미용융상태에서 용접비드가 형성되거나, 용접용와이어(3) 및 필러메탈(16)에 부착된 수분이나 불순물이 용접비드내에 존재하여 용접강도의 저하나 용접결함이 발생하게 될뿐만아니라, 아크열이 용접용와이어(3)나 필러메탈(16)의 가열에서부터 용융까지 에너지를 공급하므로 용접용와이어(3)의 송급속도와 용접속도에 한계가 있어서 고속용접이 불가능하게 되는 등의 많은 문제점이 있었다.However, since the welding wire 3 or the filler metal 16 of the conventional electric arc welder reaches the welding arc and is heated and melted, a welding bead is formed in the unmelted state, or a welding wire 3 ) And the moisture or impurities adhering to the filler metal 16 are present in the welding bead, resulting in a decrease in welding strength or weld defects, as well as arc heat, which causes the heating of the welding wire 3 and the filler metal 16. Since the supply of energy from the melting to the melting of the welding wire (3) has a number of problems, such as high speed welding is impossible due to the limitation on the welding speed.

본 고안은 상기한 제반 문제점을 해결하기 위한것으로서, 본 고안은 전기 아크용접기를 사용하여 용접작업시 공급되는 용접용와이어 및 용가제인 필러메탈이 용접아크부로 송급되기 전에 유도가열시키므로써 용접강도를 향상시킬수 있을 뿐만아니라, 용접불량을 방지할수 있는 전기 아크용접기의 고주파 유로가열장치를 제공하는데 그 목적이 있다.The present invention is to solve the above-mentioned problems, the present invention improves the welding strength by induction heating before the supply of the welding wire and the filler filler metal, which is supplied during the welding operation using the electric arc welding machine to the welding arc portion. The purpose of this invention is to provide a high frequency flow path heating apparatus for an electric arc welder that can be made as well as prevent welding defects.

상기한 목적을 달성하기 위해 본 고안은 토오치의 노즐에 용접용와이어 및 필러메탈을 가열시켜서 용접아크부로 공급하기 위한 유도가열 코일이 내장된 전기아크용접기의 고주파 유로 가열장치이다.In order to achieve the above object, the present invention is a high frequency flow path heating apparatus of an electric arc welder having an induction heating coil for supplying a welding wire and a filler metal to a nozzle of a torch to supply a welding arc.

이하, 본 고안의 일실시예를 첨부도면 제2도 내지 제5도를 참조하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 2 through 5.

제2도는 본 고안을 나타낸 종단면도이고, 제3도는 제2도의 A부분 확대도이며, 제4도는 제3도의 B-B선 단면도이고, 제5도는 본고안을 나타낸 회로도로서, 전기아크용접기에 설치된 토오치(1)의 노즐(2)내에 용접용와이어(3) 및 필러메탈(도시는 생략함)을 가열시켜서 상기 노즐(2)내의 중앙에 형성된 통공(4)을 통해 용접아크부로 공급하기 위한 유도가열코일(5)이 장착되고, 상기 노즐(2)내의 통공(4) 둘레면에는 복수개의 가스공급공(6)이 형성되어 구성된다.FIG. 2 is a longitudinal sectional view showing the present invention, FIG. 3 is an enlarged view of a portion A of FIG. 2, FIG. 4 is a sectional view taken along line BB of FIG. 3, and FIG. 5 is a circuit diagram showing the present design. Induction for heating the welding wire 3 and the filler metal (not shown) in the nozzle 2 of the oak 1 to supply the welding arc through the through hole 4 formed in the center of the nozzle 2. The heating coil 5 is mounted, and a plurality of gas supply holes 6 are formed in the circumferential surface of the through hole 4 in the nozzle 2.

이와같이 구성된 본 고안은 제2도 내지 제5도에 나타낸 바와같이, 전기아크용접기로 용접시 전기아크용접기에 설치된 토오치(1)의 토오치핸들(7) 저면에 설치된 토오치 스위치(8)를 눌러주게 되면, 가스흐름이 0.5∼2초가량 있게 되고, 용접용와이어(3)가 토오치(1)의 노즐(2)내의 중앙에 형성된 통공(4)를 통해 용접용와이어(3)가 송급되어 용접이 시작하게 된다.The present invention configured as described above has the torch switch 8 installed on the bottom of the torch handle 7 of the torch 1 installed in the electric arc welder, as shown in FIGS. 2 to 5. When pressed, the gas flow is about 0.5 to 2 seconds, and the welding wire 3 is fed through the through hole 4 formed at the center of the nozzle 2 of the torch 1 by the welding wire 3. Welding will begin.

이때, 토오치스위치(8)가 온됨과 동시에 제4도에와 같이 릴레이1(9)이 동작하여 용접기전원(10)의 직류전원(DC)이 인버터(11)를 통해 고주파 출력교류로 되어 트랜스포머(12)를 통해 적절한 출력값으로 조정되어 전원이 상기 노즐(2)의 유도가열코일(5)에 공급되어 가열됨에 따라 용접용와이어(3)나 필러메탈과 같이 상기 유도가열코일(5)내를 지나면서 유도가열코일(5)에 의해 가열되어 용접아크부로 공급하게 되고, 상기 토오치 스위치(8)가 오프됨과 동시에 릴레이1(9)이 오프되면 상기 유도가열코일(5)의 가열이 정지하게 되며, 필요시에는 릴레이1(9)의 스위치를 독립시켜서 유도가열을 계속할수 있게 된다.At this time, the torch switch 8 is turned on and at the same time, the relay 1 (9) operates as shown in FIG. 4 so that the DC power source DC of the welding machine power supply 10 becomes the high frequency output exchange through the inverter 11, thereby transforming the transformer. The power is supplied to the induction heating coil 5 of the nozzle 2 to be heated to an appropriate output value through 12 to heat the inside of the induction heating coil 5 such as the welding wire 3 or the filler metal. After passing through the induction heating coil (5) is supplied to the welding arc portion, the torch switch (8) is off and at the same time relay 1 (9) is off when the heating of the induction heating coil (5) to stop If necessary, it is possible to continue the induction heating by independent of the switch of the relay 1 (9).

따라서, 용접용와이어(3)나 필러메탈이 가열된 상태에서는 용접작업시 도전성이 향상되어 아크에너지화되는 전기 에너지의 효율이 대폭 향상되어 적은 출력전류에서도 효율적인 용접작업을 수행할수 있게 된다.Therefore, in the state in which the welding wire 3 or the filler metal is heated, the conductivity is improved during the welding operation, and the efficiency of the electric energy that is arced is greatly improved, so that an efficient welding operation can be performed even at a low output current.

이상에서와 같이, 본 고안은 전기아크용접기에 설치된 토오치(1)의 노즐(2)내에 용접용와이어(3) 및 필러메탈을 가열시켜서 용접아크부로 공급하기 위한 유도가열코일(5)이 장착되므로써, 용접작업시의 도전성 및 아크에너지화되는 전기에너지의 효율이 향상되어 적은 출력에서도 효율적인 작업을 수행할수 있으며, 용접강도를 향상시킬수 있을 뿐만아니라, 용접불량을 방지할수 있으므로 인해 용접기의 효율성 및 신뢰성을 향상시킨 매우 유용한 고안이다.As described above, the present invention is equipped with an induction heating coil (5) for heating the welding wire (3) and the filler metal in the nozzle (2) of the torch (1) installed in the electric arc welding machine to supply to the welding arc portion. As a result, the efficiency of electrical energy that becomes conductive and arc-energy during welding work is improved, so that it is possible to carry out efficient work at low output, improve welding strength, and prevent welding defects. It is a very useful design that improved.
