Ngokukhula okukhawulezileyo kwamandla ombane welizwe lam, iimfuno zokudibanisa iimpundu ze-copper-aluminiyam ziya zisetyenziswa ngokubanzi kwaye iimfuno ziya zinyuka ngokunyuka. Iinkqubo eziqhelekileyo ze-copper-aluminium welding kwimarike namhlanje ziquka: i-flash butt welding, i-rolling friction welding kunye ne-brazing. Umhleli ulandelayo uzakwazisa iimpawu zezi nkqubo kuwe.
I-Friction rolling welding okwangoku inqunyelwe kuphela kwimivalo ye-welding, kwaye imivalo edityanisiweyo inokuthi ifakwe kwiipleyiti, kodwa kulula ukubangela ukuqhekeka kwe-interlayers kunye ne-welds.
I-Brazing isetyenziswa kakhulu, kwaye isetyenziswa kakhulu kwiindawo ezinkulu kunye nezingaqhelekanga ze-copper-aluminiyam ye-butt joints, kodwa kukho izinto ezifana nokukhawuleza okuphantsi, ukusebenza okuphantsi, kunye nomgangatho ongazinzanga.
I-flash butt welding okwangoku yeyona ndlela ilungileyo yokuwelda ubhedu kunye ne-aluminiyam. I-flash butt welding ineemfuno eziphezulu kwigridi yamandla, kwaye kusekho ilahleko evuthayo. Nangona kunjalo, i-workpiece edibeneyo ayinayo i-pores kunye ne-dross kwi-weld seam kwaye amandla e-weld seam aphezulu kakhulu. Inokubonwa ukuba izinto ezingeloncedo ngayo ziyabonakala, kodwa iingenelo zayo ziye zagubungela iintsilelo zayo.
Inkqubo ye-welding ye-aluminium ye-copper-aluminium ye-welding iyinkimbinkimbi, kwaye amaxabiso eparameter ahlukeneyo kwaye ayanqanda ngokungqongqo omnye komnye, nganye eya kuchaphazela umgangatho wayo we-welding. Okwangoku, akukho ndlela yokufumanisa kakuhle umgangatho wobhedu-aluminium welding, kwaye uninzi lwazo luphumeza ukufumanisa okutshabalalisayo ukuze kuqinisekiswe amandla ayo (ukufikelela kumandla wezinto ze-aluminium), ukwenzela ukuba isebenze ngokuthembekileyo kwigridi yamandla.
Iimfuno zezixhobo ze-welding zobhedu-aluminiyam umatshini we-welding welding
1. Iimfuno zezinto eziphathekayo zomatshini we-flash butt welding;
Umgangatho we-welding consumables akufanele ube ngaphantsi komgangatho
2. Tshintshela kwiimfuno zemathiriyeli yempahla yomatshini we-butt:
Akufuneki kubekho amabala e-oyile kunye nezinye izinto ezichaphazela ukuqhuba xa u-welding ebusweni bamacandelo, kwaye akufanele kubekho ipeyinti kwi-welding end surface kunye namacala omabini.
3. Tshintshela kumatshini we-welding welding imathiriyeli yokuqala yokulungiselela:
Xa amandla ezinto eziphathekayo aphezulu kakhulu, kufuneka ahlanjululwe kuqala ukuze kuqinisekiswe ubunzima obuphantsi kunye neplastiki ephezulu ye-weldment, ehambelana nokukhutshwa kwe-slag yensimbi yamanzi ngexesha lokuphazamiseka.
4. Guqula ubungakanani bezinto zomatshini we-flash butt welding;
Xa ukhetha ubuninzi be-welding workpiece ngokobukhulu be-weldable yomshini wokuthunga, khetha ixabiso elibi lobhedu kunye nexabiso elihle le-aluminium (ngokubanzi 0.3 ~ 0.4). Umahluko wobunzima phakathi kobhedu kunye ne-aluminium akufanele udlule eli xabiso, ngaphandle koko kuya kubangela ukungonelanga okanye ukuphazamisa ukuhamba okugqithisileyo, okuya kuchaphazela kakhulu umgangatho we-welding.
5. Iimfuno zecandelo lezinto eziphathekayo zomatshini we-flash butt welding:
Isiphelo sobuso be-weld kufuneka sibe sicaba, kwaye ukusika akufanele kube kukhulu kakhulu, okuya kubangela ukuveliswa kobushushu obungalinganiyo kuzo zombini iziphelo ze-weld kwaye kubangele ukungalingani kwe-weld.
6. Ubukhulu be-flash butt welding machine workpiece:
Xa uvala i-weldment, inani lokutshisa i-flash kunye nokuphazamiseka kufuneka longezwe kumzobo ngokwenkqubo ye-welding.
