Description
Technical field
The present invention relates to welding wire technology field, particularly relate to a kind of aluminium base welding wire.
Background technology
Its welding wire adopted of existing soldering processes is made up of alloy usually, not containing flux ingredients, scaling powder is dipped in after the real needs heating of use, not only use inconvenience, and dip in add scaling powder time often due to human error, to make to dip in the scaling powder dosage added unstable, finally make welding effect unstable.Have the welding wire of medicine core class at present on the market, this kind of welding wire normally fills scaling powder or other medicinal powder in alloy tubule, but the manufacturing process of such welding wire is complicated, and production cost is high.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, providing a kind of production cost lower, during use, adding scaling powder without the need to dipping in, improve the aluminium base welding wire of one of ease of use.
In order to realize above object, the technical solution used in the present invention is:
A kind of aluminium base welding wire, it is that the flux powder of 20 ~ 30 parts and the powdered aluminum based filler mixing compacting of 70 ~ 80 parts form by weight portion, and wherein flux powder is that the potassium fluoroaluminate of 19 ~ 27 parts and the fluoaluminic acid caesium of 1 ~ 3 part mix by weight portion; Powdered aluminum based filler is that the alusil alloy of 69 ~ 76 parts and the additive of 1 ~ 4 part mix by weight portion.
Preferably, described alusil alloy silicon content is 11 ~ 14%.
Preferably, described additive is one or more in strontium, beryllium, copper and rare earth metal.
Preferably, the granularity of described flux powder is for being less than 500 orders.
Preferably, the granularity of described powdered aluminum based filler is for being less than 200 orders.
Beneficial effect of the present invention is: aluminium base welding wire of the present invention, flux powder and powdered aluminum based filler are mixed and made into aluminium base welding wire, owing to containing flux ingredients in aluminium base welding wire, therefore directly can weld with welding wire in use, exempt the trouble of adding scaling powder, improve the efficiency of welding; Not needing welder to hold the dosage of scaling powder, avoiding welder to misuse the dosage of welding compound because lacking experience, eliminate the dose error produced because individual judges simultaneously yet, be conducive to carrying out unified management to welding effect yet.Simultaneously again because scaling powder and aluminium base solder mix with pulverulence, be conducive to both Homogeneous phase mixing, make both in aluminium base welding wire, divide equally distribution with stable proportioning, add in use procedure without the need to manually additionally dipping in the scaling powder dosage instability adding scaling powder release human error and cause, aluminium base welding wire is finally made to have stable welding effect, more easily accurately control the consumption of brazing flux, simultaneously due to scaling powder powder of the present invention and aluminium base solder reasonable mixture ratio, in use also there is good welding performance.
