DETAILED DESCRIPTION

[0019] The present invention will be further described below in conjunction with specific embodiments. The purpose is only to provide a better understanding of the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0020] like Figure 1 、 Figure 2 As shown, this embodiment provides a welding area magnetic field control device. The welding gun head 1 is arranged along the Z-axis direction and includes a mounting base that can be snapped onto the welding gun head 1. Two first magnetic claws 6 are arranged on the mounting base along the X-axis direction, and two second magnetic claws 7 are arranged along the Y-axis direction. One of the two first magnetic claws 6 is of N-level and the other is of S-level. One of the two second magnetic claws 7 is of N-level and the other is of S-level. The first magnetic claws 6 and the second magnetic claws 7 are both arranged perpendicular to the mounting base, and the planes on which the two first magnetic claws 6 are located are perpendicular to the planes on which the two second magnetic claws 7 are located. The device also includes a first conductive wire 9 and a second conductive wire 10. A resistance coil 8 is provided on each of the first magnetic claws 6 and the second magnetic claws 7. The first conductive wire 9 is connected in series to the resistance coils 8 on the two first magnetic claws 6, and the second conductive wire 10 is connected in series to the resistance coils 8 on the two second magnetic claws 7. The first magnetic claws 6 and the second magnetic claws 7 are made of Q235 low-carbon steel, and the resistance coil 8 is made of 400 turns of 1 mm diameter enameled copper wire.

[0021] When the device is in use, a magnetic field is formed at the resistance coil 8 after the first and second wires 9 and 10 are energized. Then, the first and second magnetic claws 6 and 7 constrain the generated magnetic field, forming a magnetic field in the X-axis direction within the two first magnetic claws 6, and a magnetic field in the Y-axis direction within the two first magnetic claws 6. By adjusting the current and voltage on the first and second wires 9 and 10, and thereby adjusting the magnetic field strength in the X-axis and Y-axis directions, a new magnetic field is formed that is opposite to the horizontal magnetic field in the original environmental magnetic field, thereby avoiding horizontal deviation of the arc and improving welding quality.

[0022] The mounting seat comprises a torch connecting ring 2 matched with the torch head 1, an inner ring connecting arc plate 3 connected on the torch connecting ring 2, an outer ring connecting arc plate 4 provided outside the torch connecting ring 2, and the outer ring connecting arc plate 4 is connected with the torch connecting ring 2 through a connecting piece 5; two first magnetic claws 6 are provided on the inner ring connecting arc plate 3, and two second magnetic claws 7 are provided on the outer ring connecting arc plate 4; wherein, in order to ensure lightweight and non-magnetic, the torch connecting ring 2, the inner ring connecting arc plate 3, the outer ring connecting arc plate 4 and the connecting piece 5 are all made of aluminum alloy.

[0023] In order to adjust the current and voltage on the first wire 9 and the second wire 10, in the embodiment, a sliding adjustment mechanism 11 is arranged on the first magnetic claw 6 and the second magnetic claw 7, each sliding adjustment mechanism 11 comprises two legs 1101, the two legs 1101 are arranged on the first magnetic claw 6 or the second magnetic claw 7 and located on both sides of the resistance coil 8, a guide column 1102 is connected between the two legs 1101, a tab 1103 is slidably connected on the guide column 1102, the end of the tab 1103 is a sharp end, the sharp end is in contact with the resistance coil 8; a wire connecting end is arranged on one end of the resistance coil 8 and the guide column 1102, respectively, for connecting the first wire 9 or the second wire 10; through the arrangement of the tab 1103 in the structure, the number of resistance coils 8 connected to the circuit can be adjusted, so as to adjust the strength of the magnetic field in the first magnetic claw 6 and the second magnetic claw 7.

[0024] As Figure 3 After the mounting seat is clamped and fixed on the torch head 1, the lowermost ends of the first magnetic claw 6 and the second magnetic claw 7 are flush with the end of the torch head 1 or extend downward by 0.5-0.8mm from the end of the torch head 1; the magnetic field generation area is ensured to coincide with the welding space; the lower end of the first magnetic claw 6 and the second magnetic claw 7 is a hook part 12, the hook part 12 hooks to one side of the torch head 1 downward, the extension line of the hook part 12 can intersect, and the intersection point is located at 3-5mm from the lower end of the torch head 1; the magnetic field generation area is ensured to completely cover the arc area.

[0025] Considering that a large amount of heat will be generated during the arc welding process, and the coil will heat up when electrified, the high temperature of the arc welding will cause the hardness of the welded part to decrease and the impact toughness to decrease, therefore, in the embodiment, an auxiliary leg 1101 is arranged on one side of the first magnetic claw 6 on the inner ring connecting arc plate 3 and on one side of the second magnetic claw 7 on the outer ring connecting arc plate 4, a water cooling pipe is connected on the auxiliary leg 1101, and the water cooling pipe is connected with a cooling water tank through a circulating water pump; wherein, the cooling water tank is a WS-200A cooling water tank; by increasing the water cooling pipe to cool the welding area, the single welding time can be further increased.

[0026] When the original environmental magnetic field intensity is 5A / m and the magnetic field control device is not welded, the welding surface is rough, and after the device is used, the number of turns of the resistance coil 8 on the two first magnetic claws 6 on the X-axis and the number of turns of the resistance coil 8 on the two second magnetic claws 7 on the Y-axis are adjusted, and after the original environmental magnetic field direction is opposite to the 5A / m internal magnetic field, the welding surface is smooth.

[0027] It should be noted that since the direction and intensity of the original environmental magnetic field are different each time the welding operation is performed, before batch welding operation, trial welding needs to be performed in the welding area, the optimal position of the dial piece 1103 is adjusted for different original environmental magnetic fields, and then large-scale welding can be performed after recording.

[0028] The above only describes the preferred embodiment of the present application, and is not limited to the scope of the present application. Any equivalent changes made by applying the content of the present application and the drawings are included in the scope of the present application.
