Short-distance welding machine welding current wireless control system and use method thereof

Abstract

The invention provides a short-distance welding machine welding current wireless control system which comprises a welding machine and a welding gun. The power input end of the welding machine is connected with a mains supply through a load detection module, and the signal output end of the load detection module is connected with the first signal input end of a data collector. The current output end of the welding machine is connected with the current input end of the welding gun, the welding gun is connected with the welding current detection module, the signal output end of the welding current detection module is connected with the second signal input end of the data collector, and the signal output end of the data collector is connected with the first signal input end of an intelligent control terminal. According to the intelligent monitoring and controlling system, overhigh voltage and current can be avoided, early warning is performed in advance to prevent tripping, the cost is reduced, and the effects of protecting machine equipment and preventing damage are achieved. The real-time monitoring effect of monitoring data of the welding machine is achieved through a monitoring module, short-distance rapid control over the current of the welding machine is achieved through the intelligent control terminal, the working efficiency is improved, and energy conservation and low consumption are achieved.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a short-distance welding machine welding current wireless control system and a use method thereof. Background technique [0002] Welding is one of the most common technologies in industrial manufacturing, and the welding current is one of the most important welding parameters in the welding process. The weld has four welding states: flat, vertical, upward, and horizontal. In each state, the bottom layer, Filling layer, cover layer and various forms of grooves have different requirements on welding current. If the welding current is inappropriate, it will cause welding defects such as weld porosity, cracks, slag inclusions, and lack of fusion, which will seriously affect the welding quality, and the amount of rework welds will be very large, which will greatly delay the production progress. In actual construction, the welding current does not match the current value required by ...

AI Technical Summary

Problems solved by technology

[0003] 1. When the number of motors increases and the voltage rises and falls unstable, the current will not be constant and the load on the welding machine will increase; 2. The data of the welding machine is difficult to achieve real-time monitoring, resulting in unknown power consumption and unable to achieve energy-saving and low-consumption production. Efficiency; 3. During the welding process, due to the limitations of the construction site, the welding current of the welding machine cannot be directly controlled, which brings inconvenience to the operation
