Description

Co2용접기의 데이터 검출방법{Co2 welding machine detection method of data}Co2 welding machine detection method of data

본 발명은 Co2용접기로 용접시 용접과정을 데이터화하고, 측정된 데이터만으로 용접물의 품질을 확인할 수 있도록 한 Co2용접기의 데이터 검출방법에 관한 것이다.
The present invention relates to a data detection method of a Co2 welder to make the welding process data during welding with a Co2 welder, and to confirm the quality of the welded material using only measured data.

일반적으로 Co2용접은 용접토치를 통해 용접 와이어를 공급하여 모재와 사이에 아크를 발생시킴으로써 용접하되, 아크의 주변으로 CO2 가스를 방출하여 용접부를 대기와 차단함으로써 용융금속의 산화를 방지하여 용접품질을 향상시킨 용접법의 하나이다.In general, Co2 welding is performed by supplying a welding wire through a welding torch to generate an arc between the base metal and the base material.However, the welding quality is prevented by oxidizing molten metal by releasing CO2 gas around the arc to block the welding part from the atmosphere. It is one of the improved welding methods.

이러한 Co2용접은 비연속적으로 진행되는 일반 피복아크용접과는 달리 용접 와이어의 연속적인 공급을 통해 연속적인 용접작업이 가능하므로 특히 대량의 용접물 제작에 있어 작업능률이 매우 좋은 이점을 있다.Unlike general coated arc welding, which is not continuously performed, such Co2 welding is possible to continuously perform welding through continuous supply of welding wire, and thus, work efficiency is very good in producing a large amount of welding material.

하지만, 상기와 같이 종래의 Co2용접으로 생산된 용접물의 품질을 확인하기 위해 일일이 검사를 통해 확이해야 하지만 보통 대량으로 용접물을 제작하여 현실적으로 제작된 용접물 전부를 검사하기에는 작업시간을 많이 소비되고, 다수의 용접물중에 일부만 검사하기에는 전체적으로 불량제품을 완벽하게 구별하지 못하는 문제점이 있다.
However, in order to check the quality of the welds produced by the conventional Co2 welding as described above, it is necessary to confirm through inspection, but it is usually a lot of work time to inspect all of the welds produced realistically by producing a large number of welds, There is a problem that can not completely distinguish the defective product as a whole to inspect only a part of the weld.

상기와 같은 문제점을 해결하기 위해 본 발명은, 상기 종래의 Co2용접작업에 있어 용접과정을 데이터화하여 작업작에게 제공함으로써 용접데이터 만으로 용접물의 불량 여부를 알수 있도록 함에 그 목적이 있다.
In order to solve the above problems, the present invention is to provide a work by making the welding process data in the conventional Co2 welding operation is to determine whether the weld material is defective by welding data alone.

상기 목적을 달성하기 위해 본 발명은, 전기공급기, 와이어공급장치, 가스공급기, 용접토치를 포함하는 Co2용접기에 있어서, 상기 전기공급기의 출력전원부에 전류량을 측정할 수 있는 A/D컨버터가 구비되고, 상기 와이어공급장치에 와이어공급량을 측정할 수 있는 미터기가 구비되고, 상기 가스공급기의 가스공급배관에 가스공급량을 측정할 수 있는 가스유량측정기가 구비되어, 상기 A/D컨버터, 미터기, 가스유량측정기에서 측정된 측정데이터를 PLC장치에 입력되도록 케이블로 연결하며 PLC장치에 입력된 측정데이터를 프로그램에 의해 그래프화되어 디스플레이에 출력되는 것을 특징으로 한다.
In order to achieve the above object, the present invention, in the Co2 welding device including an electric supply, a wire supply device, a gas supply, a welding torch, an A / D converter capable of measuring the amount of current in the output power supply of the electric supply is provided And, the wire supply device is provided with a meter for measuring the wire supply amount, a gas flow rate measuring device for measuring the gas supply amount is provided in the gas supply pipe of the gas supply, the A / D converter, the meter, the gas flow rate The measurement data measured by the measuring instrument is connected by a cable to be input to the PLC device, characterized in that the measurement data input to the PLC device is graphed by the program and output to the display.

상기와 같이 된 본 발명은 Co2용접작업에 있어 용접과정을 데이터화하여 작업작에게 제공함으로써 용접데이터 만으로 용접물의 불량 여부를 알 수 있을뿐 아니라 작업중에도 불량 여부를 파악할 수 있는 효과가 있다.In the present invention as described above, in the Co2 welding operation, the welding process is made into data and provided to the workman, so that the welding data alone can be used to determine whether the weldment is defective or not.

또한, 용접데이터를 수집함으로써 용접물의 제품에대한 품질자료를 제공함으로써 품질을 보장할 수 있는 효과도 있다.
