Solder aluminium new facility, welder of MIG of total number word

Introductive machine is to be on foundation of inversion power source, combine computer technology, use digital signal processor (DSP) , each function that the accurate operation that carries microprocessor will come to control welder reachs working whole process, control circuit height is compositive, simplify. Normally every increase imitate welder a function should rely on to increase the hardware such as corresponding control circuit to come true, and welder of total number word needs to change computer software to be able to come true only. Accordingly, electron yuan parts of an apparatus decreased 40% , while bulk, quality is reduced, fault rate is reduced greatly. The most important is the weldability that will control electric arc character to make we got imaginary is less than through software can, as a result of slam the door the imitate that concerns with temperature drift yuan parts of an apparatus, solder control accuracy and but repeatability got very big rise. The core of welder of MIG of word of total number of 1 job process is main control system, see a picture 1. Set of count word face plate is connected to solder above all when the job parameter, main control system gives out the job to dictate to machine sending silk through RS485 number interface, pass digital signal processor at the same time (DSP) give out the job to dictate to inversion power source, solder the process begins. Soldering in the process solder actually loop of parameter classics feedback, model / several (A/D) after changeover by digital signal processor (DSP) feedback arrives main control system, main control system will be effective while face plate indicates real value parameter and set a value to undertake comparative beforehand, issue machine sending silk and power source correction statement. Because whole process is of digital signal transmit and compare, accordingly, mix very quickly, accurately interference rejection. 2 frit drop transfers extremely fused when gas protects solder, mix as power of current density, electric arc those who protect gas is different, can appear all sorts of different frit drop transfer electric arc. Welder of total number word is OK very control all sorts of electric arc conveniently, especially short circuit electric arc and pulse electric arc. Short circuit electric arc is used when CO2 solder, material of ply of capable person of welder basis mother, welding wire pledges and diametical set gives weaveform of optimal electric current, the electric arc that gains stability and splatter seldom. Solder to the welder when aluminium or stainless steel can be controlled and output first-rate pulse weaveform (graph 2) , implementation pulse electric arc transfers, accurate control can accomplish a pulse to transfer a frit drips, implementation is not had almost splatter solder, the welding wire that allows to use bigger diameter thereby solders smaller plate. If can use φ 1.

The aluminous silk of 2 Mm solders 0.

The aluminium of 8 Mm board, it is OK to divide outside cost of greatly economic welding wire, φ 1.

The aluminous silk of 2 Mm has better volume and watch area ratio, can reduce the pollution to bath, reduce stomatic ratio of defects. 3 arc length of Nextpage 　 　 dominate a picture the high difference that A of 3 medium work of body of a flight of stairs carry B is 27 Mm, solder the welding wire in the process extends length mushroom, arc length is maintained constant, frit drop transfers still is " a pulse " of drop of a frit, welding line figuration and frit are deep maintained very good consistency. These depend on the real time monitoring of system of control of total number word. The 4 welding wire when bringing arc and welder of MIG of convention receiving arc to bring arc contact workpiece, short-circuit current rises quickly, make welding wire fuses quickly explode generation electric arc, splatter very big; Welder of total number word is controallable the ascendant speed of short-circuit current, make electric arc ignition relatively downy, splatter few, anthology when deserving to pull filar welding torch, use time smoke welding wire to bring arc, can come true to be not had completely splatter bring arc. Nextpage 　 is additional, as a result of characteristic of aluminous low melting point, tall thermal conductivity, cold conditions of place removing solder hard frit is appeared, overheat of place receiving arc is burned easily wear. The special solder aluminous program that uses welder of total number word (graph 4) , can an arc with bigger set solder energy, make fuse mother capable person when electric arc ignition, electric current solders to decrease when receiving arc to lesser electric current receiving arc hole of sufficient cram arc. And a pulse is outputted when extinguish arc, the frit ball of termination of purify welding wire, with benefit at bringing arc next time (graph 5) . Face plate of 5 operations respect (graph 6) use intelligence to change a design. Outside dividing centralize adjustment knob, other if choice of welding wire diameter, solder methodological choice, solder material choice, use kiss pushbutton design, went to the lavatory already solderer operation, do not affect the solderer's visual perception to suffer again, decreased to be operated by accident. Memory solders 80 groups expert parameter. When the operation, ply of capable person of the welding wire diameter that simply uses place, material, mother inputs welder, what can obtain memory is optimal solder parameter. And the protective gas that place of material of every kinds of solder matchs was supplied on welder. Form a sth resembling a net of local area network through counting word interface to be able to be between welder, machine sending silk and welding torch, make machine sending silk and welding torch are had show and adjust solder the function of parameter, if pursue,7 are shown. Although soldering to also can be increased directly in the process or be reduced,solder electric current, need not stop machine or return adjust on face plate. The function suits remote, headroom especially or work inside container. Drop of Nextpage 　 frit transfers condition directive. When set solder parameter or solder appear in the process not the frit drop of beautiful transfers when the form, indicator light is bright. Right now, the solderer can be adjusted in time solder parameter till indicator light destroys. 6 software upgrade welder of total number word can upgrade through software the technical properties that makes welder keeps for a long time advanced. Give welder to load through carrying computer a few solder specially program, solder specially in order to satisfy material or welder art. The cost that can save a large number of updating equipment and craft experiment for the user and time (graph 8) . Upgrade through software, welder can extend a variety of soldering method: Solder of MIG/MAG spot welding, TIG, manual arc welding; Can use sincere welding wire and medical core welding wire. Additional, still have property of wonderful solder of MIG drill rod, use at soldering thin plate of plating zine plate, stainless steel. 　 of TPS2700-ALU EDITION of 7 solder aluminous expert to make the effect of aluminium of solder of welder of MIG of total number word more perfect, FRONIUS company was made on software optimize further, roll out " solder aluminous expert at the beginning of 2000 "- - TPS2700-ALU EDITION. The biggest distinction is in this type and welder of word of former TPS total number to cooperate with at increasing a low frequency pulse control, cooperate with pulse frequency is highest 5 Hz. Energy of the output when soldering and synchronism of speed sending silk are pulsatile, can acquire very even and beautiful scalelike mark welding line. Handlers is OK and aleatoric the density of ripple of set welding line, suit to have the product of special requirement to welding line exterior very much, wait like car of bicycle, slide (graph 9) . Additional, pulsatile energy out-put, make quantity of heat distributings to be controlled easily, consequently can easily thickness difference very big aluminium solder is together, reduced the demand that handles a level to the worker. Welder of word of 8 conclusion total number is to solder the new way that equipment develops. It applied brand-new digital IT, the output that control welder completely by software is characteristic, broke through the category of power source of traditional constant current, constant voltage, have very tall control precision, extremely acute electric arc is controlled, the frit drop of optimization transfers and extremely wide application flexibility. Can solder all sorts of commonly used metals, especially aluminous, the difficult solder material such as copper. CNC Milling
