Description

Technical Field

[0001] The invention relates to the technical field of power transformer oil tank processing, and in particular to a welding device and method for hiding a weld. Background Art

[0002] During the processing of the transformer oil tank, multiple welds need to be welded.

[0003] Some hidden welds in the transformer oil tank are limited by the structure, which makes it impossible for welding workers to directly observe these hidden welds, and conventional gas shielded welding guns cannot reach the hidden welds for welding operations.

[0004] Therefore, in view of the fact that some welds in the above-mentioned transformer oil tank are restricted by the structure and cannot be directly observed by people, and conventional welding guns cannot reach the weld position for welding operations, a welding device and method for hidden welds can be designed. Corrugated copper tubes are used to replace the bent steel tubes in traditional gas shielded welding guns. The angle of the corrugated copper tubes can be freely adjusted so that the welding gun can reach the welding position of the hidden welds, and a reflector can be added to assist the staff in observing the welds for operations. Summary of the invention

[0005] In order to overcome the problem that some hidden welds in the transformer oil tank are limited by the structure, resulting in the welding workers being unable to directly observe these hidden welds, and the conventional gas shielded welding gun being unable to reach the hidden weld position for welding operations.

[0006] The technical solution of the present invention is:

[0007] A first aspect of the present invention provides a welding device with a hidden weld, comprising a welding gun body, an extended corrugated copper tube, a reflector and a mounting assembly, wherein the extended corrugated copper tube is arranged at one end of the welding gun body, the mounting assembly is arranged above the welding gun body, and the reflector is arranged inside the mounting assembly.

[0008] Preferably, by setting an extended corrugated copper tube as the barrel of the welding gun body, the angle of the extended corrugated copper tube can be adjusted according to the hidden weld, so that the welding gun body can reach the welding position of the hidden weld for welding. The staff can use a handheld reflector to assist the staff in observing the hidden weld. By setting an installation component, the reflector can be fixed above the welding gun body, and the reflector can be fixed when it is inconvenient for the staff to hold the reflector.

[0009] Preferably, three groups of grooves are opened on one side of the welding gun body, and the rubber pads are arranged inside the grooves, and the rubber pads are fixedly connected to the welding gun body.

[0010] Preferably, the outer sleeve of the extended corrugated copper tube is provided with a heat-insulating rubber sleeve, and the heat-insulating rubber sleeve is slightly shorter than the extended corrugated copper tube.

[0011] Preferably, a diverter is provided at one end of the extended corrugated copper tube, and a nozzle is provided at one end of the diverter.

[0012] Preferably, a mounting frame is fixedly mounted on the periphery of the reflector, and a metal handle is fixedly mounted below the mounting frame.

[0013] Preferably, the mounting assembly includes a fixing frame, a notch, an insert block and an elastic clip. The fixing frame is fixedly mounted above the welding gun body, the insert block is arranged inside the fixing frame, two groups of notches are opened above the fixing frame, two groups of elastic clips are fixedly mounted on one side of the notch, and the elastic clip passes through the fixing frame through the notch.

[0014] Preferably, the mounting assembly includes a universal flexible rod, a mounting block, a reserved hole and a magnet. The universal flexible rod is fixedly mounted above the plug-in block, the mounting block is fixedly mounted on one end of the universal flexible rod, a reserved hole is opened on the surface of the mounting block, the magnet is arranged inside the reserved hole, the magnet is fixedly connected to the mounting block, the metal handle is located inside the reserved hole, and the metal handle is magnetically connected to the magnet.

[0015] A second aspect of the present invention provides a welding method for a hidden weld, comprising the welding device as described above. The method further comprises obtaining an image of the hidden weld based on a reflector with an adjustable angle, and welding the weld based on the image of the hidden weld.

[0016] Beneficial effects of the present invention:

[0017] 1. The present invention can facilitate welding workers to hold the reflector through the metal handle, and adjust the angle and position of the reflector by hand, so that the workers can observe the hidden welds. When it is inconvenient to hold the reflector, the reflector can be installed above the welding gun body through the installation component to observe the hidden welds. The angle can be freely adjusted by lengthening the corrugated copper tube, so that the welding gun can be extended to the position of the hidden weld, and the hidden weld can be welded, thereby realizing the welding of the hidden weld and reducing the darkness of the welding.
