Aluminous welding wire is a kind columnar strength is relative poorer soft material, and be when melt extremely sensitive to hydrogenous solubility, accordingly, its success in producing an environment depended on greatly the method that its are producing the place in the process to apply and control step are logical. Impact of function of aluminous to MIG welding wire is the biggest is the surface cast cleanness of luminosity, welding wire to spend, pitch of control of welding wire diameter and welding wire become warped be apart from and helix circumstance. One, exterior polish and degree of polish of surface of clean aluminous welding wire depend on greatly quality of performance of raw aluminous material, its character is the biggest factor that affects welding wire performance. Normally aluminous welding wire makes an appointment with the aluminium of 9mm to silk is machined via drawing again and be become by a diameter. The United States solders the chemical constituent that the standard of association is controlling these welding wire greatly. However welding wire manufacturer may be in to oneself be set to undertake stricter composition is controlled inside limits, will help the productivity that can accuse now actually, weldability, make sure its solder thereby metallic strength is characteristic. Production carries out a proof, the physical quality of filar club is very important, the impurity in the product or discontinuous can deliver in whole production process, bring about end item quality thereby serious and inferior. For this, yi Sa company applies a kind of distinctive dig to cut technical production to go out smooth and clean surface, improve the performance sending silk of welding wire thereby, can pass the excellent welding line that X- ray detects. This kind of dig cuts a technology to go effectively the discontinuous layer besides welding wire surface layer, the welding line that and make end item avoids brings about is stomatic (1) seeing a picture. Be controlled strictly and safeguard die quality to give high grade aluminous welding wire to be weighed particularly to serial production should. Produce successive high grade appearance to assure to be in the whole process that pull silk, must the die pulling silk with best service mass and special lubricant. Because different aluminium alloy needs to have different working character, the meeting in producing a course normally so undertakes to its intermediate heat treatment is operated. These intermediate heat treatment are necessary not only, and it is to assure to have proper physical characteristic place must, acquire good character sending silk thereby. After the welding wire dimension that expects to place when drawing, must undertake cleanness to aluminous welding wire, this is a very important step, this is deciding finished product to whether can solder through X- ray detects and be being achieved substantially quality standard requirement. Additional, the monitoring that operates to cleanness also is very important, yi Sa has strict test in process of welding wire production, in order to ensure clean program lasts effective. Normally of welding wire detecting is to be in drawing, cleanness and twine after finishing, undertake. After test sample is soldered, the ray that use X- will detect of welding wire complete solder characteristic. 2, control of welding wire diameter removes exterior quality feature outside, quality of the die that pull silk and it is very important to safeguard quality to control welding wire diameter and solder accurately to assuring to receive continuity. Relative to at AWS character, yi Sa produces aluminous welding wire inside more strict tolerancepublic errand limits. Diameter of this kind of strict and coherent control welding wire from this and the successive electric arc character of generation makes final user is benefited fine is much. The little difference of diameter of aluminous welding wire can make electric arc character produces tremendous change, metabolic result is with exorbitant or too low electric current volume the form is mirrorred, both metropolis produces the weld defects of a variety of forms. The Yi Sa strict control to welding wire diameter (2) seeing a picture ensured solder steadily parameter (although changing silk dish hind) , this are in those using to solder welder of craft itself and rather than the person is strict to parameter pilot is automatic the application on solder, it is a very main factor. 3, become warped be apart from and helix pesters a welding wire to have become warped successionally be apart from and helix can ensure uninterrupted report is contacted (3) seeing a picture, flowing electric arc feature and more coherent solder are appeared. Of the welding wire on bobbin of AWS norms requirement become warped be apart from and helix is application no matter be being returned automatically is semi-automatic solder equipment, should can suit those who no keeping anything from each other to send silk. Circle the welding wire on online axis become warped be apart from size to be able to use the circuit welding wire that gets off from bobbin to undertake metrical. After should cutting below one paragraph of welding wire to be put on plane from bobbin, its should form a free circle, the diameter is in most Xiaohe is the biggest between the diameter. If become warped,twine aluminous welding wire be apart from impropriety or do not coordinate, will bring about soldering the welding wire in the process is interrupted with what electrode contacts between solder mouth, the consequence of this kind of circumstance is to reduce electric arc stability, and wronger electric arc character may be caused solder discontinuous. The welding wire that gets off through going up from bobbin can use the helix case that surveys the aluminous welding wire that is circled on bobbin, welding wire takes circuit above, it is 3 ~ 4 normally. After welding wire is cut from bobbin, answer to put its on a lever, lever shows a level, welding wire circle is perpendicular hang on lever. The largest space between circle of two welding wire should not exceed the largest size of the regulation. Overmuch helix can be brought about soldering in the process, welding wire will produce free from electric mouth comes out, make its contact undesirable. This kind of circumstance to full automatic solder particularly harmful, the likelihood when soldering like the robot brings about incomplete fusion to reach not solder shows the generation that waits for weld defects. Yi Sa developed those who satisfy best requirement to become warped be apart from and helix, application is controlled and detect the method undertakes to its desired result is mixed safeguard. 4, the requirement of overall quality control in production process of aluminous welding wire of point of other quality control must be in whole production process undertake be maintenanced coherently to product quality and desired result. Yi Sa uses to be based on ISO9001 quality system to undertake aluminous welding wire is produced, this system is right the United States solders AWS A5 of association state level.

10 " naked aluminium and aluminium alloy solder electrode and welding rod standard " a complement. Additional, a lot of attestation association pledge to the product quantity and QA system undertake checkup every year, for example Lloyds shipbuilding is registered, TUV Rheinland, DB, Det Norske Veritas and Germanischer Lloyds, the test that they ask to pass pair of sample getting check is achieved examine the purpose of welding wire, include ruinous experiment with nondestructive. 5, epilogue solders to those cares quality, devote oneself to to reduce repair rate and the aluminium that improve productivity to solder manufacturer, using high grade aluminous welding wire is very important. Because even if the flaw that affects quality of aluminous welding wire, if cleanness is spent, welding wire diameter or the problem that exterior state institute may pose, last to those pursuit user of eligible aluminous weldment production, can cause huge trouble.
