其一、在铝件焊接处先涂上焊药,然后将烧热的烙铁蘸饱锡后放在焊处进行预热,待温度升高,焊药由稠变稀后再加一些焊药和焊锡,使焊锡将烙铁头包容起来,然后用烙铁头在焊接处前后摩擦,摩擦距离不要过大,一般在3~5mm之间使烙铁头处划破铝制元件表面的氧化铝膜。焊接处由于有熔锡覆盖与空气隔绝不可能产生新的氧化膜而锡则能及时沾到刚刚除去的氧化膜的铝件上。等列熔锡由圆球状变成扁平状,表明铝件已经与锡结合牢固,这时就停止摩擦并趁热擦去剩余的焊药,再与预先蘸好锡的导线头或其它元件进行焊接就很方便了。
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、首先在铝制元件的焊接处滴几滴稀盐酸用以除去表面氧化膜,稍待片刻,再加入几滴较浓的硫酸铜溶液,等到焊处全部有铜覆盖时,用水洗掉多余的硫酸铜溶液和盐酸溶液,然后用45-75W烙铁就可以进行焊接,其效果不错。
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、取一块铝放入坩埚内加温熔化,再加入2~5倍的锡熔化后待用,再按常规方法焊接十分方便。
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、在处理干净的铝表面,涂上一层溶液,用100w烙铁头上多吃锡,用烙铁头在焊接面上边摩擦边涂溶液即可。这便可以牢固的焊上。但注意:汞有毒,要在通风处焊接,且不要用剧毒的氯化汞。
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、铝件土法焊接,预先准备好锯玻璃纤维板的白粉沫,放在焊处表面,用75w烙铁在焊接面上用力摩擦直至在铝表面上附上一层锡,然后再用布将白粉沫和松香的混合物清除掉,这时就可用一般的方法焊接了,经实践此法简单,焊接效果令人满意。
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、铁屑混合,再用砂纸打光铝件面,把松香和铁粉放在焊接处光面上,用烙铁反复摩擦使铝表面吃上一层锡,然后再按一般方法即可顺利焊接。
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、先将铝件的焊接处表面打磨光亮,再滴几滴缝纫机油,油量要充足,然后用锋利小刀在焊接处来回刮几次,再用烙铁蘸上焊锡和松香在焊接处来回摩擦,锡很快就会牢固地附着在铝件上,此法也较简单、实用。
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.
