Description
Technical field
The present invention relates to welding technology field, and in particular to a kind of contact welding surface structure for improving welding performance.
Background technology
Contact weld in, generally use soldering, such as resistance brazing, induction brazing, and be brazed necessarily lead to gas and
Welding slag.These must discharge welding region, and cavity and slag inclusion, weld strength and bonding area otherwise will be formed on welding surface
Decline to a great extent.The contact of such a welding makes the service life significantly shorten with that will form melting welding on product, fall a little.Since welding is produced
Raw gas and welding slag must discharge welding region by athleticism in sticky molten state solder, so gas and welding slag are very not
Easily it is completely exhausted out, and since contact production technology, the welding surface flatness of contact are not easy to ensure, some is even in middle heart
Into pit, such gas and welding slag are just more difficult to discharge, and are easy to assemble to form cavity and slag inclusion in pit.
The content of the invention
The purpose of the present invention is exactly to solve the above-mentioned problems and provides a kind of contact welding surface knot for improving welding performance
Structure.
The purpose of the present invention is achieved through the following technical solutions：
A kind of contact welding surface structure for improving welding performance, including contact welding surface, the surface of the contact welding surface
Equipped with for discharging the gas of welding generation and the groove cluster of welding slag, the groove cluster is made of multiple straight-line grooves, and the straight line is recessed
Groove is starting point to external radiation using the centre of solder contacts.In the technical program, straight-line groove can be designed to more as needed
Welding surface, is so divided into some regions by bar, and closer to welding center, the area between two bar grooves is smaller, and gas and welding slag are got over
It is easily drained, larger sheet weld defect can be avoided the formation of, this structure can substantially improve or eliminate the chronic illness of induction brazing,
That is central cavity or dreg defect.
Further, the depth of the straight-line groove is outwards gradually deepened from contact, and solder flux decomposes what is produced during welding
Gas moves upwards, and welding slag is also lighter than solder, and also movement upwards, this inclined groove is easier to discharge gas and welding slag.
Further, the depth of the straight-line groove is in 0.05-0.1mm, width in 0.1-0.3mm, so as not to gas and
Welding slag is assembled, and the groove depth and width of straight-line groove should not be too large, in order to avoid influence welding surface in itself.
Further, the section of the straight-line groove can be any shape such as V-type, square, with specific reference to actual need
Set.
Further, the starting point of the straight-line groove is circumference, depending on the size of circumference is as needed, preferably a diameter of 1-
3mm, can avoid all grooves while originate in origin, the problem of being formed centrally within an intersection point hole, produce spot-shaped weld defect.
Further, the straight-line groove is equipped with 4-12, is arranged symmetrically two-by-two centered on starting point, and straight-line groove can be with
Continuous or segmentation.
Compared with prior art, the present invention can solve the common Welding Problems of conventional contact structure, i.e., used by setting
The gas and the groove cluster of welding slag produced in discharge welding, the gas and slag inclusion that are decomposed when welding smoothly are discharged, avoided in pit
Place's aggregation forms cavity and slag inclusion, can eliminate sheet weld defect, can substantially improve or eliminate induction brazing central cavity and folder
The defects of slag.
Brief description of the drawings
Fig. 1 is the schematic diagram of existing contact welding surface structure；
Fig. 2,3 be welding surface structure in contact of the present invention schematic diagram.
Embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Comparative example
Existing planar contacts welding surface structure as shown in Figure 1, the welding surface structure there are following defect：Sticky molten state
Solder is uniformly filled between two welding planes, and gas and welding slag are not easy to be completely exhausted out；Due to contact production technology, the welding of contact
Facial plane degree is not easy to ensure, some is even formed centrally within pit, and such gas and welding slag are just more difficult to discharge, and hold very much
Easily assemble to form cavity and slag inclusion in pit；Since welding surface full wafer uniformly connects, sheet weld defect is easily formed；Soldering
Chronic illness, central cavity or dreg defect are obvious.
Embodiment
Such as Fig. 2, the schematic diagram of welding surface structure in contact of the present invention, including contact welding surface, the surface of contact welding surface are set
The gas of discharge welding generation and the groove cluster of welding slag are useful for, groove cluster is made of multiple straight-line grooves, and straight-line groove is tactile to weld
The centre of point is starting point to external radiation.Preferable technical solution, the depth of straight-line groove are outwards gradually deepened from contact, directly
The depth of line groove is in 0.05-0.1mm, and width is in 0.1-0.3mm, in order to avoid gas and welding slag aggregation, solder flux decomposes production during welding
Raw gas moves upwards, and welding slag is also lighter than solder, and also movement upwards, this inclined groove is easier to discharge gas and weldering
Slag, the section of straight-line groove can be any shape such as V-type, square, and the present embodiment is set to V-type.To avoid all grooves all at the same time
The problem of originating in origin, being formed centrally within an intersection point hole, produce spot-shaped weld defect, the starting point of straight-line groove can basis
Need to be set as circumference, circle diameter is in 1-3mm, as shown in Figure 3.Straight-line groove is arranged as required to 4-12, the present embodiment
Equipped with 8, it is arranged symmetrically two-by-two centered on starting point.Straight-line groove can continuously or be segmented.
In the technical program, straight-line groove can be designed to a plurality of as needed, and welding surface is so divided into some regions, more
Close to welding center, the area between two bar grooves is smaller, and gas and welding slag are more easily drained, and can avoid the formation of larger sheet weldering
Defect is connect, this structure can substantially improve or eliminate the chronic illness of induction brazing, i.e. central cavity or dreg defect.The present invention can be with
The defects of solving the common Welding Problems of conventional contact structure, can substantially improving or eliminate induction brazing central cavity or slag inclusion.
