Ukuqonda umahluko phakathi kweentlobo zezihluzi ze-aluminiyam kunokunceda ukugqiba ukuba yeyiphi i-aluminiyam filler ilungele umsebenzi wakho, okanye ezinye iinketho zinokufaneleka ngakumbi.
Ukuwelda kweAluminiyam kuya kuxhaphaka njengoko abavelisi bezama ukwenza ukukhanya kunye neemveliso ezinamandla.Ukukhethwa kwesinyithi se-aluminium filler ngokuqhelekileyo kuhla kwenye yee-alloys ezimbini: 5356 okanye 4043. Ezi zimbini ze-alloys zibandakanya i-75% ukuya kwi-80% ye-aluminium welding.Ukukhetha phakathi kweebini okanye enye kuxhomekeke kwi-alloy yesiseko sentsimbi ukuba ifakwe kunye neempawu ze-electrode ngokwayo.Ukwazi umahluko phakathi kwezi zimbini kunokukunceda ukuba ubone ukuba yeyiphi esebenza kakuhle emsebenzini wakho, okanye yeyiphi esebenza kakuhle.
Enye inzuzo yentsimbi ye-4043 kukumelana kwayo okuphezulu nokuqhekeka, okwenza kube lolona khetho lungcono kwii-welds ezithintekayo.Isizathu soku kukuba yintsimbi ye weld engamanzi enoluhlu oluqina kakhulu.Uluhlu lokukhenkceza luluhlu lweqondo lokushisa apho i-material iyingxenye yolwelo kunye nenxalenye eqinile.Ukuqhekeka kunokwenzeka ukuba kukho umahluko omkhulu wobushushu phakathi kolwelo olupheleleyo kunye nayo yonke imigca eqinileyo.Yintoni elungileyo malunga ne-4043 kukuba isondele kubushushu be-eutectic kwaye ayitshintshi kakhulu ukusuka eqinile ukuya kulwelo.
I-fluidity kunye ne-capillary action ye-4043 xa i-welded yenza ukuba ifaneleke ngakumbi kumacandelo okutywinwa.Ngokomzekelo, abatshintshi bokushisa bahlala be-welded ukusuka kwi-alloy ye-4043 ngenxa yesi sizathu.
Nangona u-welding 6061 (i-alloy eqhelekileyo kakhulu), ukuba usebenzisa ubushushu obuninzi kunye nokuxubana kakhulu kweso siseko sesinyithi, amathuba okuqhekeka ayanda kakhulu, yingakho i-4043 ikhethwa kwezinye iimeko.Nangona kunjalo, abantu bahlala besebenzisa i-5356 kwi-solder 6061. Kule meko ngokwenene kuxhomekeke kwiimeko.I-Filler 5356 inezinye izibonelelo ezenza ukuba zixabiseke kwi-welding 6061.
Enye inzuzo enkulu yentsimbi ye-4043 kukuba inika indawo eqaqambileyo kakhulu kunye ne-soot encinci, eyona nto i-black streak onokuyibona kumda we-5356 weld.Lo msizi akufanele ube kwi-weld, kodwa uya kubona umgca we-matte kwi-sock kunye nomgca omnyama ngaphandle.Yi-magnesium oxide.I-4043 ayikwazi ukwenza oku, okubaluleke kakhulu ukuba usebenza kwiindawo apho ufuna ukunciphisa ukucocwa kwe-post-weld.
Ukuchasana nokuqhekeka kunye nokugqitywa okukhazimulayo zibini zezizathu eziphambili zokukhetha i-4043 yomsebenzi othile.
Nangona kunjalo, ukuhambelana kombala phakathi kwe-weld kunye nesiseko setsimbi kunokuba yingxaki nge-4043. Le yingxaki xa i-weld idinga ukuba i-anodized emva kwe-welding.Ukuba usebenzisa i-4043 inxalenye, i-weld iya kuba mnyama emva kwe-anodizing, edla ngokungafanelekanga.
Enye into engalunganga yokusebenzisa i-4043 kukuqhuba kwayo okuphezulu.Ukuba i-electrode i-conductive kakhulu, kuya kuthatha ixesha elingakumbi ukutshisa umlinganiselo ofanayo wocingo kuba akuyi kubakho ukuxhathisa okungako ukudala ubushushu obufunekayo kwi-welding.Nge-5356, ungafikelela ngokubanzi kwizantya eziphezulu zomxhesho, olungele imveliso kunye nocingo olubekwe ngeyure.
Ngenxa yokuba i-4043 iqhuba ngakumbi, kuthatha amandla amaninzi ukutshisa inani elifanayo locingo.Oku kubangela igalelo eliphezulu lobushushu kwaye kungoko ubunzima bokudibanisa izinto ezibhityileyo.Ukuba usebenza ngezinto ezicekethekileyo kwaye unenkathazo, sebenzisa i-5356 njengoko kulula ukufumana useto oluchanekileyo.Ungathengisa ngokukhawuleza kwaye ungatshisi ngasemva kwebhodi.
Enye into engalunganga yokusebenzisa i-4043 ngamandla ayo aphantsi kunye ne-ductility.Ayikhuthazwa ngokubanzi malunga ne-welding, efana ne-2219, i-2000 yochungechunge lwe-alloy yobhedu olunyangekayo.Ngokubanzi, ukuba u-welding 2219 kuwe, uya kufuna ukusebenzisa i-2319, eya kukunika amandla amaninzi.
Amandla aphantsi e-4043 enza kube nzima ukondla izinto eziphathekayo ngokusebenzisa iinkqubo ze-welding.Ukuba ucinga nge-0.035 ″ ubukhulu be-electrode ye-4043, uya kuba nengxaki yokondla ucingo kuba luthambile kakhulu kwaye luthanda ukugoba malunga nombhobho wompu.Ngokufuthi abantu basebenzisa imipu yokutyhala ukusombulula le ngxaki, kodwa imipu yokutyhala ayikhuthazwa kuba isenzo sokutyhala sibangela oku kugoba.
Ngokuthelekisa, ikholomu ye-5356 inamandla aphezulu kwaye kulula ukuyondla.Kulapho inenzuzo kwiimeko ezininzi xa ii-alloys ze-welding ezifana ne-6061: ufumana amazinga okutya okukhawulezayo, amandla aphezulu, kunye neengxaki ezimbalwa zokutya.
Ukusetyenziswa kobushushu obuphezulu, malunga ne-150 degrees Fahrenheit, yenye indawo apho i-4043 isebenza kakhulu.
Nangona kunjalo, oku kwakhona kuxhomekeke ekubunjweni kwesiseko se-alloy.Enye ingxaki enokuthi ihlangabezane ne-5000 series aluminium-magnesium alloys kukuba ukuba umxholo we-magnesium udlula i-3%, ukuphazamiseka kwe-corrosion yoxinzelelo kunokwenzeka.Ii-alloys ezifana ne-5083 baseplates aziqhelekanga ukusetyenziswa kumaqondo aphezulu.Okufanayo kuya kwi-5356 kunye ne-5183. I-Magnesium alloy substrates ngokuqhelekileyo zisebenzisa i-5052 ethengiswayo ngokwayo.Kule meko, umxholo we-magnesium we-5554 uphantsi ngokwaneleyo ukuba uxinzelelo lwe-corrosion cracking alukwenzeka.Lo ngowona matshini uqhelekileyo wokuzalisa intsimbi xa iintsimbi zifuna amandla oluhlu lwe-5000.Ihlala ingaphantsi kuneewelds eziqhelekileyo, kodwa isenamandla ayimfuneko kwizicelo ezifuna amaqondo obushushu angaphezu kwe-150 degrees Fahrenheit.
Ewe, kwezinye izicelo, ukhetho lwesithathu lukhethwa ngaphezu kwe-4043 okanye 5356. Umzekelo, ukuba udibanisa into efana ne-5083, i-alloy ye-magnesium eqinile, ufuna ukusebenzisa isinyithi esiqinileyo njenge-5556, 5183, okanye I-5556A, enamandla amakhulu.
Nangona kunjalo, i-4043 kunye ne-5356 zisasetyenziswa ngokubanzi kwimisebenzi emininzi.Kuya kufuneka ukhethe phakathi komyinge wesondlo kunye neenzuzo eziphantsi zokuqhutywa kwe-5356 kunye nezibonelelo ezahlukeneyo ezibonelelwa ngu-4043 ukufumanisa ukuba yeyiphi eyona ilungele umsebenzi wakho.
