Compared with prior art, it is an advantage of the current invention that:
The present invention is to organically combine induction brazing and the method for welding of supersonic vibration, and wherein, supersonic welding is to utilize supersonic frequency
The mechanical vibrational energy of rate (more than 16KHz), connects of the same race or dissimilar metal, quasiconductor, plastics and ceramic metal etc.
Special welding method.During metal ultrasonic welding, neither carry electric current to workpiece, do not introduce high temperature heat source to workpiece,
Frictional work, deformation energy and the most limited temperature rise being simply changed between workpiece by elastic vibration energy under static pressure, connects
Metallurgical binding between Tou realizes in the case of mother metal does not melts, and is a kind of solid State Welding.
Induction brazing is to be placed in by workpiece in the alternating magnetic field that induction coil produces, and the faradic current produced therefrom is by workpiece
Heating, makes brazing filler metal melts, and by the dissolving to welded piece surface of the melted solder liquid, and surface of the work composition is to molten
Melt the diffusion of solder and make welded piece form metallurgical binding, the infusible a kind of welding method of workpiece itself.
Induction brazing can be divided into intermediate frequency (power frequency of 500Hz～10000Hz) soldering and high frequency (100KHz～
The power frequency of 5000KHz) soldering.Frequency is high, and electric current depth of penetration is shallow, heating surfaces of work pieces speed fast, but sensing
Frequency is the highest, and the kelvin effect of alternating current is the most obvious, and the thickness of heating is the thinnest, and inside workpiece can only rely on top layer internally
Heat conduction heat, heating degree of irregularity increase.Additionally, electric current length of penetration again with resistivity and the pcrmeability of material
Relevant.Resistivity is the biggest, and the length of penetration of electric current is the deepest, and skin effect is the least.Pcrmeability is the least, and the infiltration of electric current is deep
Spend the biggest.Generally, during ferrous metal induction brazing, use is not less than the high frequency induction current of 10KHz.Copper
Less with the pcrmeability of the non-ferrous metals such as aluminum, electric current length of penetration is less, uses relatively low frequency and bigger during induction brazing
Power.
Ultrasonic assistant induction brazing technology is the principle combining induction brazing and ultrasonic bonding, utilizes sensing heating
Method makes the heating of workpiece local, brazing filler metal melts；The solder utilizing ultrasonic activation feature to promote to melt fills up rapidly table to be welded
Face, promoted solder to the dissolving of surface metal element to be welded and the diffusion to molten solder of the welding surface metallic element,
Improve the solder moistening to workpiece, thus realize the metallurgical binding of welded piece.
Ultrasonic assistant induction brazing technology also utilizes the feature of ultrasonic activation to decrease the segregation of weld metal composition, with
Time also can effectively remove the oxide-film of solder/parent material interface, it is achieved both combine in good moistening.
With deformation zinc alloy to compared with welding technology, the present invention is directed the welding of deformation zinc alloy goods, and butt welding skill
Art is directed to the welding of wire rod drawing process in production process, and purpose is different, without comparability.
Compared with the gas brazing technology of deformation zinc alloy goods, automaticity of the present invention is higher, and brazing temperature controls relatively
Accurately, the beneficially batch production of product, the skill of operator is required relatively low.
Compared with induction brazing with deformation zinc alloy goods, add ultrasonic vibration system, beneficially the solder profit to mother metal
Wet, sprawl, reduce weld metal composition segregation, improve weld strength, add the dependability of goods.
