Description
Technical field
The present invention relates to cooling water tank manufacturing technology field, especially, relate to a kind of two-layer composite cooling water tank
Welding procedure.
Background technology
The cooling water tank of two-layer composite, owing to its hydroecium is divided into big hydroecium, interior hydroecium and three layers of interior hydroecium dividing plate,
The material thickness of every layer is 1.5mm, and temperature is difficult to penetrate into innermost layer, and the fin of water tank outside is the least due to thickness, makes
Become this hydroecium easily to occur when welding on weld defect, or the internal not welding of hydroecium and cause leakage, or fin is easy
Overheated cause molten wing or stifled wing.
Summary of the invention
Present invention aim at providing the welding procedure of a kind of two-layer composite cooling water tank, to solve prior art
In, owing to the material thickness of the cooling water tank every layer of two-layer composite is the least, cause this hydroecium, when welding, weldering easily occurs
Connect and cause leakage, or the most overheated technology causing molten wing or stifled wing of fin in defect, or the internal not welding of hydroecium
Problem.
For achieving the above object, the present invention provides the welding procedure of a kind of two-layer composite cooling water tank, including following
Step: a, parts are carried out, and described parts are sprayed brazing flux；
B, described parts are assembled into assembly, described assembly is brushed brazing flux；
C, described assembly is assembled into two-layer composite cooling water tank, fills after described two-layer composite cooling water tank shaping
Upper frock；
D, described two-layer composite cooling water tank is carried out stokehold brazing flux spraying and dries, to the two-layer compound after drying
Structure cooling water tank carries out soldering oven welding；
E, the two-layer composite cooling water tank that described welding is good is carried out appearance test and leak detection, the bilayer that described inspection is qualified
Composite construction cooling water tank carries out packaging warehouse-in.
Further, the described brazing flux concentration that each stage is sprayed is different.
Further, during the welding of described two-layer composite cooling water tank, the transfer rate of conveyer belt is 620mm/min.
Further, the fin position of described two-layer composite cooling water tank, mainboard and little hydroecium spray brazing flux
Concentration ratio is 5%.
Further, it is 200mm that described two-layer composite cooling water tank puts spacing in brazier, and fin position uses
Carbon-point regulation product temperature distribution.
Further, the welded gaps of described parts is less than 0.1mm.
The method have the advantages that the welding procedure of a kind of two-layer composite cooling water tank of the present invention, should
Structure is by spraying the brazing flux of variable concentrations stage by stage, using the techniques such as soldering furnace welding to make the fin thickness of water tank outside too
In the case of little, it is possible to well avoid this hydroecium to occur not having inside weld defect, hydroecium in welding to cause to let out when welding
Dew and the most overheated generation causing molten wing or stifled wing phenomenon of fin.
Accompanying drawing explanation
Below with reference to figure, the present invention is further detailed explanation.The accompanying drawing of the part constituting the application is used for
Thering is provided a further understanding of the present invention, the schematic description and description of the present invention is used for explaining the present invention, is not intended that
Inappropriate limitation of the present invention.In the accompanying drawings:
