Device for eliminating influence of continuous high-intensity magnetic field on welding operation

Abstract

The invention relates to a device for eliminating an influence of a continuous high-intensity magnetic field on the welding operation. The device for eliminating the influence of the continuous high-intensity magnetic field on the welding operation comprises an upper electromagnetic induction device and a lower electromagnetic induction device. The upper and lower electromagnetic induction devices comprise an upper inverter welding machine and a lower inverter welding machine respectively. Positive poles of the upper and lower inverter welding machines are reliably grounded through upper and lower welding grounding wires respectively. Negative poles of the upper and lower inverter welding machines are connected with a plurality of turns of upper flexible induction coils and a plurality of turns of lower flexible induction coils wound around an upper magnetic component to be welded and a lower magnetic component to be welded. Upper electrode holders and lower electrode holders are used for welding upper and lower special demagnetization welding pieces. A groove portion is formed between the upper component to be welded and the lower component to be welded and provided with a gauss meter measuring pen connected with a gauss meter. The outer side of the groove portion is provided with a compass for measuring the direction of the magnetic induction strength and an electric welding machine wire. The electric welding machine wire is connected with an arc welding power source.

Description

technical field [0001] The invention relates to a device suitable for performing welding operations in a high-intensity, long-duration, and wide-ranging magnetic field environment, in particular to a device for eliminating the influence of continuous strong magnetic fields on welding operations. Background technique [0002] In some enterprises with large electricity consumption and energy consumption, in order to meet the usual production electricity consumption, enterprises often build self-provided power plants, such as electrolytic aluminum plants. When a power plant is installed near electrolytic aluminum equipment or other large-scale equipment that is prone to generate a strong magnetic field environment, it will have a serious negative impact on the welding operation of the construction site, resulting in strong arc magnetism during welding of high-voltage welds within the magnetic field range. The partial blowing phenomenon makes it impossible to carry out normal we...
