Problems solved by technology

[0004] When welding, if a large-scale welding machine is used, the cost will be high, and the cost pressure for enterprises with small welding volume will be high. If manual welding is used, the technical level of the welding personnel is high, the welding quality is unstable, and the welding process is difficult. Prone to sticking, easy to damage the welder

Abstract

The invention discloses a control system for an intelligent welding device. The control system comprises a fourth one-way valve, a hydraulic oil pump, a current adjusting device, a welding machine and an ammeter. The current adjusting device, the welding machine and the ammeter are connected in series. A central processing unit is connected with the ammeter, and is connected with the current adjusting device. An oil tank is connected with a hydraulic oil input end of the hydraulic oil pump. A second one-way valve and a third one-way valve are connected with a hydraulic oil output end of the hydraulic oil pump. The second one-way valve is connected with a first one-way valve and a first synchronous valve. The first one-way valve is connected with the oil tank. The first synchronous valve is connected with hydraulic cylinders. The hydraulic cylinders are connected with a second synchronous valve. The second synchronous valve is connected with a third one-way valve and a fourth one-way valve. The fourth one-way valve is connected with the oil tank. A control information output end of the central processing unit is connected with all the valves and the hydraulic oil pump. During the welding process, fluctuation of the actual current value can be automatically reduced, the actual current value can be enabled to fluctuate around the set current value, the wielding quality is beneficial for being improved, and automatic control is beneficial for being realized.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a control system of an intelligent welding device. Background technique [0002] The main part of the electric welding machine is a step-down transformer. The two ends of the secondary coil are the workpiece to be welded and the electrode. When working, the arc is ignited, and the electrode is fused to the gap of the workpiece in the high temperature of the arc. Because the iron core of the welding transformer has its own characteristics, it has the characteristics of a sharp drop in voltage, that is, the voltage drops after the welding rod is ignited; when the welding rod is stuck and short-circuited, the voltage drops sharply. [0003] During the welding operation, although the current in the circuit is equal everywhere, but because the resistance of each place is different, the resistance at the unfixed contact is the largest. According to the law of thermal effect of the cur...
