I-soldering flux

Iialloyi zokuwelda (ii-agent zokuwelda) Isilivere isetyenziswa ngobuninzi ukwenza iialloyi zokuwelda, ezizii-alloys ze-ternary ezenziwe ngesilivere, ubhedu kunye nezinc. Ukubunjwa kwesilivere kunokuvela kwi-10 ukuya kwi-80%, ubhedu ukusuka kwi-15 ukuya kwi-50%, kunye ne-zinc ukusuka kwi-5 ukuya kwi-40%. Uninzi lwezi ngxubevange zineendawo zokunyibilika phakathi kwe-650 kunye ne-775C. Ngamanye amaxesha ubhedu okanye i-tin yongezwa ukwenza i-alloy ene-melting point ephantsi. I-alloys ye-welding yesilivere isetyenziselwa ukudibanisa ezo zinyithi, oko kukuthi, xa i-alloys ye-brazing ifuna ukushisa okuphezulu kwe-welding, inokubangela ukukhula okugqithiseleyo okanye ezinye iziphumo ezinobungozi kwintsimbi kwi-weld.

Izinto zoqhagamshelwano zombane

Ukuchasana koqhagamshelwano oluphantsi lwesilivere kunye ne-conductivity ephezulu yenza ukuba ibe yintsimbi efunekayo kakhulu kwisixhobo soqhagamshelwano lombane, kodwa ukuba i-voltage yoqhagamshelwano iphezulu okanye kukho i-arc, ubomi bomnxeba owenziwe ngesilivere ecocekileyo abukho ixesha elide. Uluhlu lwezinto ezenziwe ngesilivere kunye neentlobo ezahlukeneyo zesinyithi kunye nentsimbi ephikisayo ziye zaphuhliswa zibe zizixhobo zoqhagamshelwano zombane ezinamandla aphezulu. Ezi zinto aziyiyo i-alloys kwindalo kuba amacandelo awanyibiliki. Ziyalungiswa ngeteknoloji ye-metallurgical, oko kukuthi, ngokucinezela kunye ne-sintering umxube womgubo ococekileyo wecandelo ngalinye. Izinto ezahlulwe kwisilivere kunye ne-tungsten, isilivere kunye nesitshixo, isilivere kunye ne-nickel, isilivere kunye negraphite, isilivere kunye ne-oxidation picks, kunye nesilivere kunye ne-oxide oxide zisetyenziswa njengezinto zoqhagamshelwano zombane. Ukuchasana nokunxibelelana kwabo kuphezulu kancinci kunoko kwesiqhamo esibuthuntu kodwa kukufutshane nesilivere encinci esebenzayo kunye nemigca ephindwe kane abafikelela kuyo phantsi komkrolo otyheli.
