其一、在鋁件焊接處先涂上焊藥，然后將燒熱的烙鐵蘸飽錫后放在焊處進行預(yù)熱，待溫度升高，焊藥由稠變稀后再加一些焊藥和焊錫，使焊錫將烙鐵頭包容起來，然后用烙鐵頭在焊接處前后摩擦，摩擦距離不要過大，一般在3～5mm之間使烙鐵頭處劃破鋁制元件表面的氧化鋁膜。焊接處由于有熔錫覆蓋與空氣隔絕不可能產(chǎn)生新的氧化膜而錫則能及時沾到剛剛除去的氧化膜的鋁件上。等列熔錫由圓球狀變成扁平狀，表明鋁件已經(jīng)與錫結(jié)合牢固，這時就停止摩擦并趁熱擦去剩余的焊藥，再與預(yù)先蘸好錫的導(dǎo)線頭或其它元件進行焊接就很方便了。
First, apply solder on the welding place of aluminum parts, then dip the hot soldering iron into tin and put it on the welding place for preheating. When the temperature rises and the solder turns from thick to thin, add some solder and solder to make the solder contain the soldering iron head, and then rub the soldering iron head before and after the welding place. The friction distance should not be too large, Generally, the aluminum oxide film on the surface of aluminum components is scratched at the soldering iron head between 3 ~ 5mm. Because the welding joint is covered with molten tin and separated from the air, it is impossible to produce a new oxide film, and tin can be stained on the aluminum parts with the oxide film just removed in time. The equal row of molten tin changes from ball shape to flat shape, indicating that the aluminum parts have been firmly combined with tin. At this time, it is very convenient to stop friction and wipe off the remaining flux while hot, and then weld with the conductor head or other components dipped in tin in advance.
其二、在鋁制元件的焊接處滴幾滴稀鹽酸用以除去表面氧化膜，稍待片刻，再加入幾滴較濃的硫酸銅溶液，等到焊處全部有銅覆蓋時，用水洗掉多余的硫酸銅溶液和鹽酸溶液，然后用45-75W烙鐵就可以進行焊接，其效果不錯。
Second, first drop a few drops of dilute hydrochloric acid at the welding position of aluminum components to remove the surface oxide film. Wait a moment, and then add a few drops of concentrated copper sulfate solution. When all the welding positions are covered with copper, wash off the excess copper sulfate solution and hydrochloric acid solution with water, and then weld with 45-75w soldering iron. The effect is good.
其三、取一塊鋁放入坩堝內(nèi)加溫熔化，再加入2～5倍的錫熔化后待用，再按常規(guī)方法焊接十分方便。
Third, take a piece of aluminum and put it into the crucible for heating and melting, then add 2 ~ 5 times of tin for melting, and then wait for use. It is very convenient to weld according to the conventional method.
其四、在處理干凈的鋁表面，涂上一層溶液，用100w烙鐵頭上多吃錫，用烙鐵頭在焊接面上邊摩擦邊涂溶液即可。這便可以牢固的焊上。但注意：汞有毒，要在通風(fēng)處焊接，且不要用劇毒的氯化汞。
Fourth, apply a layer of solution on the cleaned aluminum surface, eat more tin on the 100W soldering iron head, and apply the solution while rubbing on the welding surface with the soldering iron head. This can be firmly welded. But note: Mercury is toxic. Welding should be carried out in a ventilated place, and do not use highly toxic mercuric chloride.

其五、鋁件土法焊接，預(yù)先準(zhǔn)備好鋸玻璃纖維板的白粉沫，放在焊處表面，用75w烙鐵在焊接面上用力摩擦直至在鋁表面上附上一層錫，然后再用布將白粉沫和松香的混合物清除掉，這時就可用一般的方法焊接了，經(jīng)實踐此法簡單，焊接效果令人滿意。
Fifth, aluminum parts are welded by native method. Prepare the white powder of sawing fiberglass board in advance, put it on the welding surface, rub it on the welding surface with 75W soldering iron until a layer of tin is attached to the aluminum surface, and then remove the mixture of white powder and rosin with cloth. At this time, it can be welded by the same method. After practice, this method is simple and the welding effect is satisfactory.
也可取松香、鐵屑混合，再用砂紙打光鋁件面，把松香和鐵粉放在焊接處光面上，用烙鐵反復(fù)摩擦使鋁表面吃上一層錫，然后再按一般方法即可順利焊接。
It is also advisable to mix rosin and iron filings, polish the aluminum surface with sandpaper, put rosin and iron powder on the smooth surface of the welding place, rub repeatedly with a soldering iron to make the aluminum surface eat a layer of tin, and then weld smoothly according to the general method.
后方法之六、先將鋁件的焊接處表面打磨光亮，再滴幾滴縫紉機油，油量要充足，然后用鋒利小刀在焊接處來回刮幾次，再用烙鐵蘸上焊錫和松香在焊接處來回摩擦，錫很快就會牢固地附著在鋁件上，此法也較簡單、實用。
The sixth method is to polish the surface of the welding part of the aluminum part first, and then drop a few drops of sewing oil. The amount of oil should be sufficient. Then scrape it back and forth at the welding part with a sharp knife, and then rub it back and forth with a soldering iron dipped in solder and rosin at the welding part. The tin will soon be firmly attached to the aluminum part. This method is also simple and practical.
