Abstract
The invention discloses an automobile fuel tank partition assembly and welding technology. The automobile fuel tank partition assembly and welding technology includes the following steps that A, a fuel tank partition is assembled to the corresponding position in a fuel tank forming shell according to drawing requirements, welding is conducted only on the fuel tank forming shell and the arc positions of the four corners of the fuel tank partition, the fuel tank partition is firmly fixed in the fuel tank forming shell, and other portions of the fuel tank partition are not welded; B, carbon dioxide arc shielded welding is carried out on the arc welding portions of the four corners, and the mixed gas of carbon dioxide and argon is selected as welding shielding gas. The automobile fuel tank partition assembly and welding technology has the advantages that the welding quality of carbon dioxide arc shielded welding is easily detected, control is easy in the welding process, the toughness of weld joints is higher than that of spot welding, welding is firmer, and tearing is not prone to occurrence; the problems that welding spot pits are generated in the plane of the fuel tank forming shell after spot welding is conducted, and the plane of the fuel tank forming shell is not even are solved, and by adoption of carbon dioxide arc shielded welding, the reliability of the fuel tank forming shell is improved.
Description
Technical field
The present invention relates to the production method of fuel tank of vehicle, particularly relate to a kind of vehicle fuel separator for container welding equipment technology.
Background technology
The function of fuel tank of vehicle stores fuel oil.Fuel tank partitioner is assemblied in fuel tank internal, has vibrated cushioning effect to fuel oil, has the effect supporting fuel tank skeleton simultaneously.The fixed form of dividing plate straight flange flange place's spot welding is generally selected in the assembling of (irony) fuel tank partitioner.Under vehicle-mounted state, fuel oil high vibration impacts fuel tank partitioner, spot welding place solder joint is concentrated stressed, causes solder joint to come off, drawing crack housing, cause fuel tank seepage.
Summary of the invention
In order to solve the problem, ensure fuel tank partitioner assembling firmly, improving the service life of fuel tank assembly, the invention provides a kind of vehicle fuel separator for container welding equipment technology.
To achieve these goals, technical scheme of the present invention is as follows:
Vehicle fuel separator for container welding equipment technology, is characterized in that, comprise the following steps:
A, fuel tank partitioner is assembled to by drawing the inner relevant position of fuel tank Shaped shell after, only weld with the foursquare arc place of fuel tank partitioner at fuel tank Shaped shell, fuel tank partitioner is fixedly secured at fuel tank Shaped shell inner, all the other positions of fuel tank partitioner are not all welded;
B, foursquare arc welding position adopt carbon dioxide gas arc welding, select the mist of carbon dioxide and argon gas as welding protection gas.
Further, in step, the fit-up gap≤0.5mm of the foursquare arc of fuel tank Shaped shell and fuel tank partitioner.
Further, in step, fuel tank Shaped shell adopts individual layer single-run welding with the welding of foursquare arc place of fuel tank partitioner, weld length 110-120mm, welding and assembling height 2mm, fusion penetration 1mm, allow fuel tank Shaped shell outer surface to produce weld mark, but can not through welding, ensure that fuel tank partitioner firm welding is reliable.
Beneficial effect of the present invention is, the SMAW that the productivity ratio of carbon dioxide gas arc welding is common is high, and welding cost is low, and fusion penetration is large, easily carries out locus welding, simultaneously CO
2air-flow has stronger cooling effect, and welding deformation is little, is applicable to fuel tank partitioner (thin plate) welding; Select carbon dioxide (CO
2) and the mist of argon gas (Ar) as welding protection gas, arc burning is stablized, spatter is few argon arc feature that it has, has oxidisability simultaneously, improves appearance of weld, improve fuel tank Shaped shell cleaning inside degree; The welding quality of carbon dioxide gas arc welding easily detects, and welding process easily controls, and the toughness of weld seam is better than spot welding, makes welding more firm, not easily tears; Spot welding rear fuel tank Shaped shell plane is avoided to produce solder joint pit, the problems such as fuel tank Shaped shell plane out-of-flatness; Adopt carbon dioxide gas arc welding to not only increase the presentation quality of fuel tank Shaped shell, and improve the reliability of fuel tank Shaped shell.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that vehicle fuel separator for container of the present invention is welded on fuel tank Shaped shell inside.
