CMT is cold metal transfers solder technical abbreviate, say according to Elb-Form company, CMT cold metal transfers soldering is a kind of welder that does not produce any solder broken bits to splatter art technology. The installation that passes 2 months is debugged, CMT cold metal transfers solder the product that equipment can use at large quantities of quantities to produce 6 kinds to differ. Solder when the component with different large wall, the deep work that asks to have ply of good welding line should transfer poor work, and be had only in intermediate zone of welding line ply a few heat is conducted. In the meantime, from the point of exterior quality and the point of view that safety protects, welding line is in also not the solder broken bits that be patient of splatters appears. In this kind the requirement falls, traditional aeriform protection solders (MSG) already helpless, because gas protects what often need to undertake filling solder rehabilitate and solder broken bits after solder to clear,work, and these become the bottleneck that restricts gas to protect solder technology to undertake soldering to different ply plank. Solder to these difficult problem, mr HelmutHaspl of company of Elb-Form finite liability expresses, the CMT cold metal that produces by Fronius company research and development transfers solder equipment can solve all problems, assure successful manufacturing process thereby, avoid repair. The main product of Elb-Form company is appearance complex, use inside high pressure changes model treatment craft (IHU) production cavity steel structure, chromic - nickel steel structure with aluminium alloy structural member. Basically build course of study, autocycle and bicycle manufacturing industry to provide high strength for auto industry, flying mechanism structural member of material of alloy of Bao Bi, light structure. Change in the course model after treatment, these spare partses will solder in the robot solder in equipment make larger part, use in order to offer manufacturer home. CMT cold metal transfers solder the technology is in by Fronius company the CMT cold metal that revealed on exposition of European plank technology 2004 transfers solder the technology is a kind of new-style welder that splatters without solder broken bits art technology. Alleged cold metal transfers, the inverting that those who point to is the short electric arc below digital control means and welding wire sends silk monitoring. Among them inverting sends silk the system by before, hind two welding wire that work in coordination carry an orgnaization to comprise, make thereby the transportation of welding wire the process is shown send silk discontinuously. Evacuation silk orgnaization sends silk ahead according to constant rate sending silk, filar orgnaization sends to dictate according to what control a system the electric welding wire that dominating pulse type with the frequency of 70Hz is carried before. Digital type solders control what the system can know electric arc is generated to begin time, reduce automatically solder electric current, go out till electric arc, the welding wire of type of the pulse in adjusting is carried, welding wire of type of this kind of pulse carries what improved drop of welding wire frit effectively to transfer. Go up from welding wire in frit drop drippy later, digital control system rises again solder electric current, send welding wire ahead further. Later, generate afresh solder electric arc, begin new round solder process. This kind " cold - hot " the alternant change between was reduced greatly solder hot generation, CMT -- absolutely not the CMT of effective edge tool of repair is cold metal transfers solder technical abbreviate, say according to Elb-Form company, CMT cold metal transfers soldering is a kind of welder that does not produce any solder broken bits to splatter art technology. The installation that passes 2 months is debugged, CMT cold metal transfers solder the product that equipment can use at large quantities of quantities to produce 6 kinds to differ. Adjust after ending, CMT cold metal transfers solder equipment can assure automatically extremely tall solder quality decreased to solder heat is in be conducted mediumly by weldment. Besides, still can realize a variety of functions: Can set the parameter that frit drips correctly, realize better welding line ply to transfer, have very tall solder speed and do not produce any splattering. Introduce according to Fronius company, this equipment huge improved soldering productivity, can assure effectively by weldment solder quality. After the job of experiment test and verify that gets is sure Elb-Form company is interior in the experiment had 2 months, declare ends satisfactorily. In the manufacturing test and verify of these 2 months, according to large quantities of conditions that estimate production, be opposite respectively of 6 kinds of products solder quality and dependability undertook test and verify. The mobile ceiling bracket of car of canopy of open of Tigra of new-style Ou Bao and heat exchanger canal are the delegate product of two models. Mobile ceiling bracket is the thin wall structural member that material of a kind of aluminium alloy makes, the flowguide after containing, have the function that prevents capsize protection. Use CMT cold metal to transfer solder the plank of the bracket tubal material of arc of ceiling of technical general activity and flowguide solders an organic whole, the structural member that can assure to solder not only satisfies the requirement of safe technology, and look very smooth also on the exterior, achieve the requirement of quality of class A surface, broke through what what Elb-Form company achieves before this to solder quality. Soldering when heat exchanger is in charge of, need solders moire canal together, and the change of the length measure that because be heated place is caused,must avoid moire canal. In the meantime, the wall of moire canal is large for 0. 4mm, and as thick as wall of spare parts of moire canal connective for 2mm. Cold to CMT metal transfers solder facilities will tell, have a wall large difference is bigger soldering is without a problem, it can make sure good welding line transfers, do not arise to any waste residue splatter and be conducted by weldment medium quantity of heat is least also. Productivity and the actual production situation that assure Elb-Form company what produce character amount reliably prove: Use CMT cold metal to transfer solder the technology makes the technical level of its enterprise had substantially leap, and can think its user improves the finished product of higher value. New-style solder of the technology introduce, make the productivity of Elb-Form company and product quality reached new level inside short time. CNC Milling
