WE53 low aluminum welding aluminum wire low temperature cryogenic solid aluminum rod if you are the first to use it, be sure to look at the intentions of the instructions several times, and in strict accordance with the instructions to operate during the operation, it is best to go first to a waste aluminum, a little thin on the plane to find what the correct shape effect, results in the future to find the right shape, and then find a little practice of waste products! If it can not make it, please do not use WE53, thanks! Stressed: genuine WE53 low aluminum wire from Weiou Ding (Tianjin) Welding Technology Co., Ltd., please use genuine WE53 welding principle: the use of all the available heat directly to the base material 400 ℃ (high temperature can not be low), by thermal conductivity of molten base metal wire forming, complete operation three times, cleaning clean draw wire --- --- --- On the basis of bottoming bottoming brushed on and then draw the wire. Welding WE53 heating: If we recommend the use of a thin piece of porous WE53 special gun, burning gas, if it is thick pieces, or recommend the use of conventional oxygen acetylene gas welding torch, if it is possible to consider other mass induction heating, heat conduction heating etc., since the heating efficiency is also directly affects the production efficiency. Attention to detail WE53 operation: 1) the surface of the base material must be clean, that is clear that welding wire surface oxide layer need to use sandpaper or a blade shave 2) blade polished off with sandpaper or wire surface oxide residue WE53. 3) The temperature of the base material must reach 400 ℃, the temperature of the soldering process, including the base material must maintain 400 ℃, and the temperature can be high not low. 4) taboo deliberately to burn with a flame WE53 wire, the base material after the temperature reaches 400 ℃, the wire will naturally depend on the thermal conductivity of molten parent metal. WE53 wire under way: one side is heated by heat welding, again designated by WE53 welding wire, just like a match, like, draw wire angle is 60 degrees -80 degree angle, draw look back, and then back to the program, This operation is repeated until the WE53 plan to base metal wire with a thin layer on top of the correct results, as will be zoned to red iron candle above the kind of effect (if it is the same as earthworms, then climbed on the description of the base material designated angle the intensity is not right or wrong way to use fire to the wire). When using WE53 draw wire base metal surface was time to avoid the heat as much as possible to avoid what the direct use of heat to burn the wire can be moved to a nearby heat source and not be able to completely remove the welding heat, this benefit is to avoid heat loss. WE53 wire temperature control: under the wire in accordance with the method described above can be avoided insensitive to temperature control burn thin aluminum master, because you are in while heating wire draw WE53 process is actually a test temperature process because the temperature of the base material is not enough, WE53 wire to the base metal is not melted above the base metal is not melted, indicating the base metal temperature is not enough, you do not have to worry about the temperature enough to burn the base metal, heated to safely continue. WE53 special stainless steel small brush useful: 1) Surface treatment before welding, get rid of the aluminum surface oxide film, layman's terms brush "fluff." 2) When the draw wire to the base material is heated above the post, this time with a small brush to wipe WE53 molten steel welding layer to the base metal capillary, and then easily welded back a second time, in other words, only after two times of welding is complete welding, soldering the second time on the basis of the first pass were brushed on, so as to exhibit a good wettability. Analysis of possible problems: non-stick base material: 1) One may have to re-weld surface is oxidized or dirty no clean 2) base metal temperature is not enough, but the use of fire to burn WE53 wire, the wire is melted, But the base metal temperature is not enough, WE53 like earthworms climbed above the base material, it is difficult to see, it is considered to be non-stick base material. Welding Weld formation: 1) base metal temperature is not enough. 2) brushed the area is too large, brushed the welding area as long as the temperature is enough, then brushed off, it is not the formation of Weld, but brushed brushed finishing part is mandatory, but in fact at this time ending The base metal temperature was not enough, if you want to avoid this, at the time just brushed brushed into place, you should always add heat to reach the melting point of 400 degrees to work.
