Specific implementation mode
It in order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below will be in the embodiment of the present invention
Technical solution be clearly and completely described.The person that is not specified actual conditions in embodiment, builds according to normal condition or manufacturer
The condition of view carries out.Reagents or instruments used without specified manufacturer is the conventional production that can be obtained by commercially available purchase
Product.
The welding method of the embodiment of the present invention is specifically described below.
A kind of welding method, according to the design information on welding main part in opening bar-shaped trough on the welding main part, in bar shaped
Solder is buried in slot, welding component is embedded in bar-shaped trough and is resisted the solder, heating makes solder fusing.
Wherein, it is, for example, the welding position etc. joined a class in the middle of the course to weld design information on main part, is believed according to the design on welding main part
Breath, corresponding to open up bar-shaped trough, the depth of bar-shaped trough is selected according to the projected depth of plate, such as deep-controlled is 5-
8mm。
The selection of solder can be cream solder, sheet solder etc..It is preferred with sheet solder, the embedded amount of sheet solder is easy
Control, thickness are also more easy to adjust.
It should be noted that in same bar-shaped trough, inbuilt solder does not need to be equal thickness, with sheet solder
For, in the different zones of bar-shaped trough, sheet solder can be arranged thicker or thinner, in this way according to actual welding
It needs, welding fluid controllable quantity everywhere does not overflow.
For bar-shaped trough, preferably equal deep bar-shaped trough, i.e. slot is rough uniform depth.In some realities of the present invention
It applies in mode, the i.e. controllable welding fluid amount of the number of plies by controlling sheet solder, it is more convenient to open up bar-shaped trough in this way, integral solder
Process is simpler.
It should be appreciated that in a part of the embodiment of the present invention, stepped groove can also be selected, that is, passes through the difference of control flume
The depth of position, while embedded sheet solder so that the solder after embedded is concordant, and then to control welding fluid amount.
It, can be in advance to solder when in certain embodiments of the present invention, in using sheet solder embedment bar-shaped trough
It carries out repairing sanction, the dimension scale of solder is made to be matched with bar-shaped trough, and be not in sliding after preventing in turn in solder embedment slot.
, will be in welding component (such as plate) insertion groove after in solder embedment bar-shaped trough, and resist and be embedded in advance
Solder, at this time since in the equal embedded groove in the both sides of plate, structure is relatively stable, meanwhile, welding fluid is difficult to overflow bar-shaped trough.
After plate is embedded in bar-shaped trough, welded by solder fusing and by welding main part and welding component.
It is welded by above-mentioned welding method, the accuracy of welding can be significantly improved.
It is further preferable that welding welding fluid after component embedded groove in order to prevent overflows while enhancing the stability of welding, welding
Component is before insertion, and in the edge chamfering of welding component, usually, by taking the welding component of 2mm thickness as an example, chamfering can be with
It is opened up according to 0.5mm or so, two seamed edges at the corresponding edge in the embedded groove of welding component open up symmetrical chamfering.
For welding the case where polylith welds component on same block welding main part, can carry out in the following manner：
In welding main part open up at least two bar-shaped troughs, will in slot bury solder, will at least two block welding components one by one
In two bar-shaped troughs of corresponding insertion and solder is resisted, steel ball is filled in form branch to welding component in adjacent solder component part
Support, heating make solder fusing.
This is because after a block welding component is embedded in, it is also necessary to embedded other welding components, in the process, by
Also unfused in solder, welding component also less stable is easy to happen inclination, and more preferably embodiment is：In adjacent weldering
It connecing and fills in steel ball between component, steel ball can make to form support between adjacent welding component, when keeping welding component insertion
State prevents from during melting solder, shifting.
The diameter of steel ball is selected according to the spacing of adjacent solder component, for example, spacing is between two adjacent solder components
7.00mm, you can to select the steel ball of diameter 6.98mm.
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
