Before the step of obtaining the segmented measurement result of the welding piece measured by the three-dimensional magnetic field measuring instrument in an alternative embodiment, the method further comprises:
demagnetizing the welding piece, and carrying out sectional welding spot-bonding on the demagnetized welding piece;
and measuring the welded piece after the segmented welding is fixed by the three-dimensional magnetic field measuring instrument to obtain the segmented measurement result.
Specifically, a special demagnetizer is adopted to perform primary demagnetizing treatment on the front and back surfaces of a plurality of welding pieces, so that the magnetic field on the surface of a welding seam is below 3 gauss, and the sharp corner part is below 10 gauss.
Further, splicing and sectional welding spot-bonding are carried out on the welding pieces subjected to the demagnetizing treatment according to welding requirements, for example, the welding seams of the welding positions are subjected to sectional welding spot-bonding on the front side and the back side by adopting an argon arc welding (Tungsten Inert Gas, TIG) method, the butt joint assembly of the pipe is realized, the spot-bonding is carried out once every 300-400mm, the length of the spot-bonding welding seam is 10-15mm, and after the spot-bonding, the gap between the butt joint surfaces is not more than 0.1mm.
Further, the three-dimensional magnetic field measuring instrument is adopted to carry out sectional measurement on the magnetic field distribution of the surface of the pipe joint, so that a sectional measurement result is obtained.
In this embodiment, through demagnetizing the welding piece to eliminate the ferromagnetism of welding material, avoid the magnetic field to cause the influence to electron beam welding, thereby improved electron beam welding's quality, and carry out segmentation detection to the welding piece after the demagnetization, can further judge the influence of surplus magnetic field intensity to the electron beam in the welding process through the segmentation monitoring result that obtains, thereby prevent in advance the processing, prevent because surplus magnetism to the influence that electron beam welding caused, avoid producing welding defect, further improve electron beam welding quality.

the segmented measurement results are input into Kang Moshu mole physical field coupling simulation software (COMSOL Multiphysics) and the electron beam deflection angles for each of the weld locations are output.
In an alternative embodiment, said arranging said canceling magnetic field coils for said welding location according to said electron beam deflection angle comprises:
judging whether the canceling magnetic field coil is arranged according to a comparison result of the electron beam deflection angle and a preset threshold value;
if yes, arranging the canceling magnetic field coils at the welding position, and determining the magnetic field strength of the canceling magnetic field coils according to the deflection angle of the electron beam and the preset canceling magnetic field relation.
In an optional embodiment, the determining whether to set the canceling magnetic field coil according to the comparison result of the electron beam deflection angle and a preset threshold value includes:
when the deflection angle of the electron beam is smaller than the preset threshold value, judging that the canceling magnetic field coils are required to be arranged at the welding position;
when the deflection angle of the electron beam is larger than or equal to the preset threshold value, judging that the canceling magnetic field coil is not required to be arranged at the welding position, and demagnetizing the welding piece.
In an alternative embodiment, said arranging said canceling field coils to said welding location comprises:
determining the deflection direction of the electron beam according to the deflection angle of the electron beam;
and determining the position of the canceling magnetic field coil according to the deflection direction of the electron beam.
In an alternative embodiment, the canceling magnetic field relationship satisfies:
C＝α×A；
wherein C is the magnetic field intensity, A is the deflection angle of the electron beam, and alpha is the magnetic field intensity coefficient.
Specifically, according to the comparison result of the electron beam deflection angle and the preset threshold value, it is determined whether or not the canceling magnetic field coil is arranged at the welding position, for example, the preset threshold value is set to be 5 °, when the electron beam deflection angle is smaller than 5 °, the canceling magnetic field coil needs to be set at the welding position, and the magnetic fields of the welding position are mutually canceled by the canceling magnetic field coil, so that the electron beam at the welding position will not deflect when the electron beam is performed, and when the electron beam deflection angle is greater than or equal to 5 °, it is indicated that the welding position has stronger magnetic field intensity, the demagnetizing process needs to be performed again on the welding piece after the demagnetizing process is performed again until the obtained electron beam deflection angle is smaller than 5 °.
Further, when the deflection angle of the electron beam is smaller than a preset threshold value, determining the deflection direction of the electron beam according to the deflection angle of the electron beam, for example, selecting one side position direction of the welding position as a positive direction, then the other side as a negative direction, when the deflection direction of the electron beam is a positive direction, then the corresponding deflection angle of the electron beam is a positive direction angle, and when the deflection angle of the electron beam is a negative direction, then the corresponding deflection angle of the electron beam is also a negative direction angle, therefore, when the deflection angle of the electron beam is a positive direction angle, the canceling magnetic field coil is arranged on one side of the welding position in the positive direction, and when the deflection angle of the electron beam is a negative direction angle, the canceling magnetic field coil is arranged on one side of the welding position in the negative direction.
Further, according to the relation between the deflection angle of the electron beam and the canceling magnetic field, the magnetic field strength of the canceling magnetic field coil is calculated, for example, the deflection angle of the electron beam is 4 degrees, and the magnetic field strength coefficient is 0.01, then the magnetic field strength of the canceling magnetic field coil is 4×0.01=0.04 mT, that is, the magnetic field strength of the canceling magnetic field coil is 0.04 millitesla.
In this embodiment, the magnetic field strength of the counteracting magnetic field coil to be set is obtained according to the deflection angle of the electron beam, and the specific position of the counteracting magnetic field coil is determined according to the deflection angle and direction of the electron beam, so that the counteracting magnetic field coil can more accurately counteract the residual magnetic field of the welding position, and finally the electron beam is not deflected during welding, so that the welding defect caused by the deflection of the electron beam is avoided, and the welding quality and welding efficiency of welding are improved.
