Indlela yokuchonga uhlobo lweingxubevange yobhedu?
Ubhedu olumhlophe, ubhedu, ubhedu obomvu (okwabizwa ngokuba “lubhedu olubomvu”), kunye nobhedu (oluhlaza-grey okanye olungwevu-tyheli) lwahlulwa ngombala.Phakathi kwabo, ubhedu olumhlophe kunye nobhedu kulula kakhulu ukwahlula;ubhedu obomvu ubhedu olusulungekileyo (ukungcola <1%) kunye nobhedu (amanye amacandelo e-alloy malunga ne-5%), okunzima ukuhlukanisa.Xa i-noxidized, umbala wobhedu obomvu ukhanya ngakumbi kunobhedu, kwaye ubhedu buncinci okanye bubumnyama obuphuzi;emva kwe-oxidation, ubhedu obomvu buba mnyama, kwaye i-bronze i-turquoise (i-oxidation enobungozi yamanzi) okanye i-tshokoleta.
Ukwahlula kunye neempawu ze-welding zobhedu kunye ne-alloys zethusi:
(1) Ubhedu olusulungekileyo: Ubhedu olusulungekileyo ludla ngokubizwa ngokuba lubhedu olubomvu.Ine-conductivity elungileyo yombane, i-thermal conductivity kunye ne-corrosion resistance.Ubhedu olucocekileyo lumelwe ngunobumba + T}} (ubhedu), njenge-Tl, T2, T3, njl. Umxholo we-oksijeni uphantsi kakhulu, kunye nobhedu olucocekileyo olungekho ngaphezu kwe-0.01% lubizwa ngokuba yi-oxygen-free copper, emele i-TU (i-copper free), njenge-TU1, i-TU2, njl.
(2) Ubhedu: Ingxubevange yobhedu enezinki njengeyona nto idibanisayo ibizwa ngokuba lubhedu.Ubhedu lusebenzisa +H;(mthubi) uthetha i-H80, i-H70, i-H68, njl.
(3) Ubhedu: Ngaphambili, ialloyi yobhedu nenkcenkce yayibizwa ngokuba lubhedu, kodwa ngoku ezinye iialloyi zobhedu zibizwa ngokuba lubhedu.Ngokuqhelekileyo kusetyenziswa i-tin bronze, i-aluminium bronze kunye ne-min bronze.Ubhedu lumelwe ngu "Q" (cyan).
Iimpawu zokuwelda zobhedu kunye nealloyi zobhedu zezi: ① kunzima ukudityanisa kwaye kulula ukonakala;② kulula ukwenza iintanda ezishushu;③ kulula ukwenza imingxunya
Ukuwelda kobhedu kunye nobhedu kusetyenziswa ukuwelda kwerhasi, ukuwelda kwegesi engasebenziyo, ukuwelda kwe-arc entywilayo, ukujongisa kunye nezinye iindlela.
I-alloys yobhedu kunye ne-copper ine-conductivity efanelekileyo ye-thermal, ngoko ke kufuneka ifudunyezwe ngokubanzi ngaphambi kwe-welding, kwaye amandla omgca omkhulu kufuneka asetyenziswe kwi-welding.I-hydrogen tungsten arc welding ithatha udibaniso oluhle lwe-DC.Kwi-welding yegesi, idangatye elingathathi hlangothi okanye ilangatye elibuthathaka le-carbonization lisetyenziselwa ubhedu, kwaye idangatye elibuthathaka le-oxidizing lisetyenziselwa ubhedu ukunqanda ukuvela kwe-zinc.
