As the board that heads film in recent years (the zine plate that be like plating) grow in quantity uses in industry, plating zine plate and aluminium, magnesium serves as together provide the data of foreground most and be taken seriously by people place more and more. But how galvanization plank solders effectively to perplexing project technology personnel all the time, because zincic melting point is 420 ℃ about, volatilize ℃ of temperature 908, the high temperature electric arc of common fusion welding (make an appointment with ℃ of 4000 of 3000 ～ ) make many zinc evaporate necessarily, bring about all sorts of weld defects thereby, destroyed zincic layer fight corrode a function. Now, these problems already became the past, the innovation technology of this appreciate German Cloos company development- - solder of drill rod of MIG electric arc, developed have solder of drill rod of MIG electric arc to solder the special welder of expert system. Solder of drill rod of MIG electric arc also is belonged to in some sense extremely fused gas protects solder (MAG) . The copper that it uses low melting point base welding wire replaces carbolic steel welding wire, hot input amount is small when soldering, mother capable person won't be fused, at the same time of zinc evaporate fall send lowest, the corrosion resistance that increased welding line can (cupreous radical welding line is anti-corrosive also) . Ensured plating zine plate is better thereby more effective solder. Solder of drill rod of MIG electric arc is in industry already gained huge success in actual application, a lot of automobile manufacturing industry more and more application cupreous radical welding wire produces important part. Latter, solder of MIG drill rod still is used solder be not film board (like alloy steel, blame alloy steel, stainless steel, copper) , achieve favorable result likewise. Many galvanization small plate is used at the car to make, deepfreeze, bldg. , ventilated make with heat addition establishment and furniture wait for a domain. Galvanization becomes important steely and anticorrosive method, because zinc can form compact covering layer in steely surface,be not just, still have cathode to protect the effect because of zinc, when galvanization layer damaged, it still can protect action to prevent iron to pledge mother capable person is corroded through cathode, effect of this kind of protection but outspread the area that does not have covering layer to 2mm of 1 ～ , because this galvanization protects the cut of plank and cold working effectively,the zinc of the micro-crack that cause and close welding line burns caustic area, prevent to begin to rust from here. Zincic melting point is 420 ℃ about, volatilize temperature is 908 ℃ , this is gone against solder, when electric arc firm one ignition volatilized. Zincic volatilization and oxidation can bring about stomatic, incomplete fusion and crackle to affect electric arc stability even, because this solders,the method with first-class talent of plating zine plate is to reduce hot input to measure. A kind of feasible method is to use material of drill rod solder to solder plating zine plate, this kind of the most commonly used welding wire is cupreous silicon alloy (be like CuSi3) with cupreous aluminium alloy. Because these welding wire are medium cupreous content is high, melting point is reduced relatively (about ℃ of 1080 of ～ of 1000 ℃ , decide by alloy component) , at this moment mother capable person is not fused still, such connect is connect of drill rod solder actually. Recommending use protection to enrage normally is argon gas, however experimental proof CuSi3 also can use the gas mixture that contains a few oxygen or carbon dioxide to make protection enrage, the stability of such electric arc is better. Advantage of solder of drill rod of MIG electric arc: 1) welding line is not had corrode 2) splatter rarely 3) galvanization layer burns caustic little 4) hot input amount is small 5) welding line easy machining 6) the MAG solder that seams an area to be able to be protected 7) to raise security tradition by cathode nearly (namely CO2 gas protects solder) solder galvanization, those who damage operation personnel is healthy. Solder with solder of drill rod of MIG electric arc, hot input amount is small, solder soot and splatter to be reduced greatly, can improve working environment effectively. Following copper alloy can regard galvanization of solder of drill rod of MIG electric arc as the welding wire of plank: ● A202M: Order of data of SG-CuSi3 (2. A207M of 1461) ● : Order of data of SG-CuSi2Mn (2.
522) is nonstandard ● A2115/8M: Order of data of SG-CuAL8 (2.
In 0921) real work, application of CuSi3 welding wire is the widest. Its advantage is welding line hardness low, treatment of the machine after solder is easy. The performance of going from place to place of welding wire depends on greatly the content of silicon, silicon content is higher, bath liquidity is better, this can satisfy the connect of little space. CuAL8 welding wire basically is used solder packet of aluminium board rolled steel. In addition copper alloy of a lot of other also can make welding wire of drill rod solder: ● A216M: A200SM of SG-CuAL8Ni2 ● : A203/6M of SG-CuSn ● : Solder of SG-CuSn6 MIG drill rod uses range: Drill rod solder can use MIG electric arc to solder alloy steel of low-alloy steel, blame and stainless steel, main use still solders the board that the surface has film. The low melting point of the welding wire that it uses reachs the character such as the input of low quantity of heat when soldering, reduced workpiece to seam the volatilization of area and zinc of welding line the reverse side nearly. Solder of MIG drill rod is the same as MAG solder same, can solder all sorts of type connect and whole place solder, although be in,stand downward, stand to fall with the circumstance that admires solder up, also can achieve satisfactory result, solder the level that speed can reach MAG solder likewise (100cm/min) . Current, solder of drill rod of MIG electric arc already had many practice application in car and bearing structure. Tall even strong steel (for example bicycle bracket) also used solder of MIG drill rod solder method. Because use short circuit,basically be what transferring MAG solder solder goes out is protruding welding line, this reduced the tensile strength of welding line; On the other hand, with traditional drill rod solder will make pipe generation is out of shape apparently. And solder of drill rod of MIG electric arc overcame above the defect of two kinds of methods, amount of input of the workpiece when soldering is small, welding line is smooth. Summary: 1.
Solder of drill rod of MIG electric arc to soldering power source has very firm demand. 2.
German CLOOS company was offerred for broad user solder high-poweredly equipment (like MC3, MC4 and welder of pulse of QUINTO series complete digitlization) the solder of MIG drill rod that applies extensively at galvanization thin plate produces practice. CNC Milling
