Description
Technical field
The utility model relates to technical field of welding materials, and in particular to a kind of included brazing flux type solder ring.
Background technique
The conventional brazing technique of the industries pipeline such as air-conditioning, refrigerator is the side being brazed using silk or strip solder Manual flame
Formula, gas brazing temperature is high, heating is fast, but the problems such as be easy to appear uneven heating, burning, and brazed copper etc. is thermally conductive fast
Heating time is longer when metal.Silk or strip solder glue brazing flux and use or brazing flux is coated in workpiece in advance before heating when soldering
On, solder dosage not can guarantee, and is easy to appear weldering leakage, welds the problems such as stifled, and consequent is to do over again, reprocess or even scrap,
The waste of solder and raw material is caused, manufacturing cost is increased.In addition, solder glues brazing flux or the in advance operation of coating brazing flux, increase
Process and operating time before welding, and increase a variable again in soldering processes, thus affect welding consistency and
The stability of quality.Such soldering processes are complicated, production efficiency is low, is not easy to accurately control the dosage of brazing flux, brazing flux often occur
Excessive or non-uniform phenomenon is added, brazing flux waste, the also more difficult cleaning of brazing flux residue, perishable connector are caused；The welding matter of connector
Amount depends on the level of operator more, is also easy to produce defect.
With the development of high-frequency induction welder, application of the induction brazing technique in piping connection is advanced by leaps and bounds
Development.Induction brazing is easy to operate, heating is relatively uniform, good economy performance, does not need heating whole part, allows quickly local add
Heat, with the high-intensitive element of the smallest loss of strength connection.In order to save solder and generate the stable connector of quality, solder is controlled
Usage amount, preforming solder is using more and more preforming solders according to the customization of weld seam form into certain form
Solder, the most common form are cyclic annular.
Currently, the compound solder ring of solder brazing flux applied in pipeline soldering only has medicine core solder ring and included brazing flux type pricker
Expect ring, since the processing performance of medicine core solder is restricted by its ingredient, there are deep shaping property differences for many ingredient medicine core solders
Defect can only be prepared into item, it is difficult to prepare circlewise medicine core solder preparation method：Solder rolling is become band, then solder band rolls
At U-type groove, brazing flux is added, finally heals up to form the medicine core solder of O shape tubular structure by the rolling of multi-pass pass, then pass through
Drawing tube reducing is prepared into medicine core solder, and what the soldering of the industries pipeline such as air-conditioning, refrigerator most had application prospect is included brazing flux type solder
Ring.However, there are three disadvantages for presently disclosed included brazing flux type solder ring：One, in order to easy to assembly, included brazing flux type solder
Ring internal diameter is commonly greater than by the outer diameter on welded tube road, in addition included brazing flux type solder ring Internal and external cycle has brazing flux layer, brazing flux layer is too thick,
Cause to be conducted heat between welded tube road and weld-ring when induction heating slower high-frequency induction brazing when heating by welded tube road, by by welded tube road
Included brazing flux type solder ring is transferred heat to, fusing wetting, joint filling influence soldering effect to by welded tube road gap after reaching brazing filler metal fusing point
Rate；Two, it carries often containing the inorganic matters such as boric anhydride, potassium fluoride in the brazing flux layer of brazing flux type solder ring, easy to absorb moisture and the chip off-falling that falls off,
And the brazing flux layer after the moisture absorption has corrosivity, the solder core that heavy corrosion is coated by brazing flux layer, especially copper-phosphorus brazing alloy be oxidizable,
It is easily corroded and " getting rusty ", the appearance and service performance of included brazing flux type solder ring is seriously affected after solder core " getting rusty ", in order to
Avoid brazing flux layer moisture absorption post-etching solder core, it has to select the brazing flux that moisture absorption is weaker, lead to the very low brazing flux master of flux activity
Acting on is that removal is not oxidized by weldering metal by weldering metal oxide film surface, protection, and flux activity refers mainly to oxide film dissolving
Ability；Three, the included brazing flux type solder occurred currently on the market is taken and excessive organic adhesive is added in brazing flux layer
Its moisture absorption is avoided, organic adhesive and brazing flux are prepared by mixing into flux paste, is then coated with into included brazing flux type solder China specially
Sharp CN202804495 U discloses " a kind of solder for being coated with coating ", it is that brazing flux lamination is coated on solder stick；Signed article
" development of coating brazing solder " describes coating brazing solder, and coating is that organic adhesion agent and solder flux are first blended in one
Rise, then by the solder flux with binder again extrusion to filiform brazing solder surface., containing big in this included brazing flux type solder
The organic adhesive of amount, organic adhesive bonding agent in brazing process are thermally decomposed, are carbonized, and generate a large amount of pernicious gases, no
Environment is only polluted, also damages the health of operator, very not environmentally；Carbon remains in generate in brazed seam and be mingled with simultaneously, reduces
It is brazed reliability.
