英语翻译
Soldering and Brazing
Soldering and brazing processes are similar in principle in that the filler material melts at a comparatively low temperature and this liquid filler is drawn by capillary action into the small gap between the parts being joined .One major advantage of soldering and brazing operations is that the joint is made at fairly low temperatures so that there is little heat distortion of parts and little change to the microstructure of the parent metal.Soft solders are comparatively weak but hard solders (brazes) may have tensile strengths in the range 400~500MN/㎡.
Soft soldering
Soft solders are alloys of tin and lead or tin/lead with antimony,cadmium or bismuth and have melting temperatures in the range 70~300℃.For soldering to be effective the liquid solder must ‘wet’the surface of the metal to be soldered.This means that some alloying must take place between a constituent of the solder and the metal to be joined.The type of alloying that occurs may cause formation of a solid solution or the formation of an intermetallic compound.In soft solders tin will form intermetallic compounds with both copper and iron.A liquid solder will only wet a metal surface that is clean and grease free so all surfaces to be soldered must be perfectly clean.A thin oxide film will quickly form on a fresh metal surface and so a soldering flux is necessary to dissolve this oxide layer.The flux used is either zinc chloride solution or of the resin type.
The most commonly used heat source for soft soldering is a soldering iron with an electrically heated copper bit.
Hard soldering
Hard soldering ,or brazing makes use of copper-base alloys with melting tempertures ranging from 620℃ to 900℃ for making the joint.Again,the materials to be joined must be clean and a flux must be used.The most commonly used flux is borax .Borax melts at 750℃ and is a good solvent for many metal oxides.For brazing at lower temperatures than this alkali metal fluorides are used as fluxes.
As with soft soldering the parts to be joined are prepared and fitted together.During brazing the molten filler metal is drawn by capillary action into the joint.The most commonly used heat source for brazing is the oxy-gas torch.The gas used is propane or acetylene.Generelly,a neutral or slightly reducing flame is used ,but when brazing copper a slightly oxidizing flame should be used to reduce the possibility of hydrogen embrittlement.

焊接和钎焊
焊接和钎焊过程原理相似,填充材料在一个相对低的温度熔化而这种液体填充剂在毛细作用下进入要被焊接的两部分之间.焊接及铜焊一个主要的好处是连接操作是在较低的温度,所以零件很少受热变形而且几乎不会改变金属微观组成.软焊料是相对较软但是很有延展性的焊料(比如铜)延展范围为400 500MN /㎡.
软钎焊
柔软的合金焊料有锡合金和铅或锡锑、镉或铋,熔化温度70 300℃范围.液体焊料必须表面很“湿润“这样才能使焊接高效的.这意味着在焊料和被连接的金属之间的组成部分会产生合金.这种类型的合金的产生可能导致固溶体和金属互化物的产生.用软焊料锡会与铜和铁反应生成金属互化物.液体焊料只会湿润金属表面,而所有的焊接面都要做到干净的无油脂保持绝对清洁.氧化膜薄就会迅速形成一种新的金属表面所以必须要用一种焊剂来溶解这个氧化层.使用的焊剂要么是锌氯溶液要么树脂的类型.最常用的是热源软焊为烙铁和铜电焊头.
硬焊
硬焊,或钎焊是利用铜基合金,融化的温度从620℃到900℃来焊接.再说一遍,材料必须是洁净而且焊接处必须使用熔剂.最常用的熔剂是硼砂.硼砂融化在750℃,对许多金属氧化物是一种优良的溶剂.对钎焊来说使用熔剂比使用碱金属氟化物操作温度温度更低.
作为连接处的软焊料因该准备好拟合在一起.在焊接时熔态钎料通过毛细管作用进入焊接处.最常用的热源钎焊是气焊焊炬.燃气常用丙烷或乙炔.通常来说,火焰要用中等或小火焰,但当铜有轻微的氧化时火焰应该被用来减少氢的可能性脆化作用.

锡焊接和铜焊接
锡焊接和铜焊接原则上是相似的。就是将填充材料处在适当低的温度状态（液态状），液态焊接剂熔化开，通过扩张使其填充到即将焊接部分的小空隙间。锡焊接和铜焊接的一个主要优点就是，焊接是在一个相当低的温度下进行，所以对部件的外部形状和母件的内部结构影响都是极其微小的。锡焊接剂是相对较弱但坚固的，焊接剂有400~500MN/㎡的抗张强度。
锡焊接
锡焊接剂是锡和铅的合金或是锡\铅同锑，镉或铋的合金。熔点温度范围在70~300℃。锡焊接的效果不错。液态焊接剂必须湿润将要焊接物体的表面。也就是说一些合金必定会填充到焊接剂和将要焊接的金属之间。这种合金的产生可能产生固体合成物或者金属化合物。因为锡焊接剂锑与铜和铁会形成金属化合物。液态焊接仅仅湿润金属表面所以将要焊接部分的表面一定要驱尘和除油脂以做到充分清洁。清洁金属的表面很快就会形成一层薄薄的氧化层所以焊接剂很可能溶解这层氧化层。焊接剂通常是氯化锌合成物或合成树脂类。
最常用的热源焊接为电烙铁铜焊头。
铜焊接
铜焊接，或铜锡焊接是在铜焊料合金的620℃ 到 900℃熔点范围内进行焊接℃。再次说明，物体焊接清洁和焊接剂是必需的。最常用的焊接剂是硼砂。硼砂合金在750℃时是除金属氧化层很有效的物质。由于铜的熔点低于碱性金属氢氟化合物得熔点，所以其被用于焊接剂使用。
通过锡焊接，使部件间有序牢固连接起来。通过铜焊接，融化的金属通过扩张得以延展焊接起来。铜焊接最常用的热源是氧气焰，气体通常是是丙烷或乙炔。通常用稳定的或者逐渐减少的火焰，当铜焊接剂刚开始氧化时火焰要适当，以降低氢脆化几率。
