冷壓焊特性

　　冷壓焊特性

優點

焊接時不需求添加焊絲、焊han劑ji等deng焊han接jie資zi料liao。由you於yu焊han接jie在zai室shi溫wen下xia停ting止zhi，不bu需xu求qiu加jia熱re安an裝zhuang，焊han接jie本ben錢qian低di，構gou造zao簡jian單dan，能neng夠gou節jie約yue大da量liang電dian能neng，並bing儉jian省sheng由you於yu焊han接jie加jia熱re需xu求qiu的de輔fu助zhu時shi間jian。不bu運yun用yong焊han劑ji，接jie頭tou不bu需xu求qiu焊han後hou清qing洗xi，不bu存cun在zai接jie頭tou運yun用yong中zhong因yin焊han劑ji惹re起qi的de腐fu蝕shi問wen題ti。焊han接jie參can數shu由you模mo具ju尺chi寸cun決jue議yi，不bu需xu求qiu像xiang電dian弧hu焊han接jie那na樣yang調tiao理li電dian流liu

缺陷

冷壓焊接部分變形量大，搭接接頭有壓坑。對某些異種金屬，如Cu和Al焊(han)後(hou)構(gou)成(cheng)的(de)焊(han)縫(feng)在(zai)高(gao)溫(wen)下(xia)會(hui)因(yin)擴(kuo)散(san)作(zuo)用(yong)而(er)產(chan)生(sheng)脆(cui)性(xing)的(de)化(hua)合(he)物(wu)，使(shi)其(qi)塑(su)性(xing)和(he)導(dao)電(dian)性(xing)明(ming)顯(xian)降(jiang)落(luo)
，這(zhe)類(lei)金(jin)屬(shu)組(zu)合(he)的(de)冷(leng)壓(ya)焊(han)接(jie)頭(tou)隻(zhi)能(neng)在(zai)較(jiao)低(di)溫(wen)度(du)下(xia)工(gong)作(zuo)。由(you)於(yu)受(shou)焊(han)機(ji)噸(dun)位(wei)限(xian)製(zhi)
，冷(leng)壓(ya)焊(han)工(gong)件(jian)的(de)搭(da)接(jie)板(ban)厚(hou)和(he)對(dui)接(jie)的(de)斷(duan)麵(mian)不(bu)能(neng)過(guo)大(da)。工(gong)件(jian)的(de)硬(ying)度(du)也(ye)受(shou)模(mo)具(ju)材(cai)質(zhi)的(de)限(xian)製(zhi)而(er)不(bu)能(neng)過(guo)高(gao)。
