Gas protected tungsten pole argon arc welding automatic controlled system adapter

Abstract

An adapter for a gas shielded argon arc welding automatic control system in the field of welding technology, including a welding power supply interface circuit, a manual control circuit, an automatic control circuit, a computer interface circuit, a first switch, a second switch, a third The switching switch is used to connect the welding power supply and the computer during the gas shielded tungsten arc welding process to realize the automatic control and manual control of the welding process by the computer. The invention adjusts the welding current and wire feeding speed in real time through the computer during the welding process. size, and real-time acquisition of welding process status information such as arc start, arc stop, and pulse arrival in the gas shielded argon tungsten arc welding process, so as to realize effective automatic control of the welding process.

Description

technical field [0001] The invention relates to a device in the field of welding technology, in particular to an adapter for an automatic control system of gas shielded tungsten arc welding (GTAW). Background technique [0002] At present, most welding machines used in industrial production adopt manual control. With the development of welding technology, it is urgent to use intelligent equipment such as computers to automatically control the welding process. Usually, a computer is used to automatically control the welding process, and it is necessary to use a data acquisition card or use the I / O port of the computer to connect to the welding power supply and then control and detect the welding process through programming. Due to the interference of high frequency and high voltage in the welding process, if the computer is directly connected to the welding power source, it will cause great damage to the computer. Therefore, it is necessary to design a switching circuit to ...

AI Technical Summary

Problems solved by technology

However, the system can only automatically control the pulse welding process, and cannot control the AC welding process, and the system does not have the function of controlling the arcing process, and manual control of the arcing process is still required

In addition, the system does not have the automatic detection function of the welding process status, and cannot detect the welding process status in real time, so it cannot effectively control the welding process

This system completely removes the manual control circuit. When manual welding is required, the circuit of the system needs to be rebuilt, which is extremely inconvenient to use.
