Abstract
The utility model discloses a braze welding connector capable of enabling welding flame to enter a lap-joint section, which comprises a first base material and a second base material. A flaring lap-joint section is arranged on the periphery of a pipe opening of the first base material, and the second base material is inserted into the lap-joint section of the first base material. The braze welding connector is characterized in that a welding material is arranged on the second base material, and the distance L1 between the welding material and the tail end of the lap-joint section can enable the welding flame to enter the lap-joint section. A certain distance between the welding material and the tail end of the lap-joint section is reserved so that the flame can directly enter the gap of the lap-joint section during welding to heat scaling powder to enable the scaling powder to be fully smelt, the role of the scaling powder is played, oxidation of the metal surface can be effectively avoided, and welding quality of the pipe opening is improved.
Description
Technical field
The utility model relates to a kind of soldering connection interface.
Background technology
At present, the mode that the pipe welding is adopted usually is the overlap joint section that directly scolder tightly is trapped among the soldering opening place, welds then; This welding method is because metal surface heating meeting and airborne oxygen generation oxidation reaction; Produce oxide, the formation of oxide makes the solder fluidity variation of melted by heat; And be easy to generate the weld defect of slag inclusion; Welding mouth of pipe quality is descended,, select for use the fusing point of scaling powder must be lower than scolder so need usually to add solid shape or pasty state scaling powder during welding.Add and be coated to scaling powder near the mother metal solder surface and the welding junction man-hour, scaling powder fusing earlier formed cover layer at tube surface when its effect was welding, and metal surface and air are completely cut off, and prevented the formation of oxide.
Scaling powder needed fusing earlier when the characteristics of this solder technology were welding, and scaling powder just can better play a role, protective money metal surface, anti-oxidation.But scolder tightly is trapped among the overlap joint section at soldering opening place, and as shown in Figure 1, scolder has blocked flame when welding; Flame is difficult to enter into overlap joint section, and the temperature of overlap is lower, occurs easily that scolder has melted and does not also reach the phenomenon of fusing point at the scaling powder of overlap joint section; Scaling powder does not have the effect that prevents burning; Be solid-state scaling powder after being heated on the contrary and mix with scolder easily, form the slag inclusion phenomenon, reduce welding effect.
Summary of the invention
The technical problem that the utility model will solve provides a kind of welding junction that can make welding flame get into the overlap joint section.
In order to solve the problems of the technologies described above, the technical scheme that the utility model will adopt is:
A kind of soldering connection interface; Comprise first mother metal and second mother metal; The mouth of pipe periphery of first mother metal is provided with enlarging overlap joint section, and second mother metal inserts in the overlap joint section of first mother metal, it is characterized in that; Be equipped with scolder on said second mother metal, the distance L 1 between scolder and the overlap joint section end can make welding flame enter in the overlap joint section.
Preferably, scolder is 3mm～5mm place apart from the terminal distance L 1 of overlap joint section.
Preferably, the gap L 2 between said second mother metal outer surface and the overlap joint section is 0.07mm～0.15mm.The external diameter of first mother metal and second mother metal is Φ 4mm～Φ 10mm.
Further, said first mother metal of the utility model or second mother metal are copper material or aluminium.Said scolder is copper base or aluminium base scolder.
The invention also discloses a kind of method that above-mentioned soldering connection interface is welded, may further comprise the steps:
A) before the welding second mother metal is inserted in the overlap joint section that the first mother metal mouth of pipe periphery extends out;
B) at the second mother metal surface-coated fusing point at soldering opening place than the low-melting scaling powder of scolder;
C) scolder is placed on second mother metal, the distance L 1 between scolder and the overlap joint section end can make welding flame get in the overlap joint section.
Scolder of the utility model and the certain distance of the terminal maintenance of overlap joint section; Flame can directly get into overlap joint section during welding gap heating scaling powder, scaling powder fully melt; The effect of performance scaling powder prevents oxidation on metal surface effectively, has improved mouth of pipe welding quality.
Description of drawings:
Fig. 1 is a welding junction structure of the prior art;
Fig. 2 is the soldering connection interface structure of the utility model.
The specific embodiment
Below in conjunction with description of drawings and specific embodiment the utility model is further specified.
Fig. 2 is the utility model soldering connection interface structure; Comprise first mother metal 1 and second mother metal 4; In the present embodiment, the external diameter of first mother metal 1 and second mother metal 4 is Φ 4mm～Φ 10mm, and the material of first mother metal 1 or 4 employings of second mother metal is copper material or aluminium; Be provided with outward extending enlarging overlap joint section 6 at the mouth of pipe place of first mother metal 1; Second mother metal 4 inserts in the enlarging overlap joint section 6 of first mother metal 1, is equipped with scolder 3 on second mother metal, and the distance L 1 between scolder 3 and the overlap joint section terminal 6 can make welding flame enter in the overlap joint section 6.This distance is preferably 3mm～5mm place.Gap between second mother metal, 4 outer surfaces and the overlap joint section 6 is preferably 0.07mm～0.15mm.
The welding method of the utility model is: at first, second mother metal 4 is inserted in the overlap joint section 6 that first mother metal, 1 mouth of pipe periphery extends out; Secondly, at second mother metal, the 4 surface-coated fusing points at soldering opening place than scolder 3 low-melting scaling powders 5; Last scolder 3 places on second mother metal 4, and the distance L 1 between scolder 3 and overlap joint section 6 ends can make welding flame get in the overlap joint section 6.The scolder 3 of the utility model is preferably copper base or aluminium base scolder.
Fig. 1 has showed mouth of pipe welding junction structure in the prior art; As shown in the figure; The difference of interface structure is in its structure and the utility model; Its scolder 3 is close to the mouth of pipe of first mother metal 1, receives stopping of scolder 3 to be difficult to put in the overlap joint section 6 during flame heat, causes scaling powders 5 in the overlap joint section 6 fully not to be heated and can not play the effect that prevents the mother metal oxidation.
The scolder 3 distance overlap joint sections 6 of the utility model have certain distance, for flame gets in the overlap joint section 6 convenience are provided, and low-melting scaling powder 5 is preferentially melted, and cover the mother metal surface, prevent that mother metal is oxidized.On the other hand, the scolder 3 of back fusing is penetrated in the overlap joint section 6 through capillarity under the effect of scaling powder 5 and fills up the gap between overlap joint section 6 and second mother metal 4 surfaces, thereby has improved weld bond intensity.
