Ukutshisa i-coating-kunye kunye ne-post{1}}i-weld corrosion ziingxaki ezixhaphakileyo xa i-spot welding galvanized steel, i-tin{2}}iitheminali ezinepleyiti, kunye nezibiyeli ezigqunyiweyo zeenkqubo zokugcina amandla. I-weld inokubonakala yamkelekile ekuqaleni, kodwa ilahleko egqithisiweyo yokwambathisa inokuthi iveze isiseko sesinyithi, inciphise ukuxhathisa kwe-corrosion, kunye nokunciphisa ubomi benkonzo kwiindawo ezifumileyo okanye ezinzima.
Kwizinto ezigqunyiweyo, isitshixo asikona nje ukusebenzisa umsinga ophakamileyo. Iziphumo ezizinzileyo zixhomekeke kumandla okukhutshwa alawulwayo, amandla afanelekileyo e-electrode, imathiriyeli efanelekileyo ye-electrode, indawo yokusebenza ecocekileyo, kunye nokhuseleko lweposi{1}}.
Kutheni le nto iGalanti kunye neTinki-iMathiriyeli ePlaytiweyo iqhelene nokutshiswa ngokutyabeka{1}}Kutyhutyha kunye nokuMhlwa Ngexesha lokuWelding?
Ngaphambi kokuphumeza amanyathelo okukhusela, kuyimfuneko ukuqonda izizathu ezisisiseko zomonakalo we-coating ukusuka kwizinto zombini kunye nemibono yokuziphatha kwe-thermal. Oku kuqonda kusisiseko sokuseka okuthembekileyoiparameters spot welding for galvanized steel usebenzisa oomatshini bokuwelda ukugcina amandla.
Indawo eNyibilikayo ePhantsi yeMatya ngoyena nobangela wokutsha{0}}Nga
Izinto ezenziwe ngegalati kunye nenkcenkce- zibonisa ubuntununtunu benkqubo ephezulu ngexesha lokumelana ne-welding kuba izinto zokugquma zineendawo zokunyibilika ezisezantsi kakhulu kunesiseko sesinyithi. Ngenxa yoko, iingubo zithande ukunyibilika okanye zibe ngumphunga kwangethuba ngexesha lomjikelo wewelding, idala ukutshiswa kwendawo{2}}kwizowuni.
Le theyibhile ilandelayo ithelekisa iimpawu zokunyibilika zemathiriyeli esetyenziswa ngokuqhelekileyo:
Uthelekiso lweNdawo yokuNyibilika eqhelekileyo yeMpahla ePlated
| Izinto eziphathekayo | Indawo yokunyibilika ( isidanga ) | Iimpawu zeNkqubo | Welding Impact |
|---|---|---|---|
| IZinc (Zn) | 419 | Iba ngumphunga ngokulula | Umngcipheko ophezulu wokutshiza |
| Itoti (Sn) | 232 | Inyibilika ngokukhawuleza | Umngcipheko wokutshisa ubuso |
| Intsimbi ephakathi | 1370–1510 | Uzinzile ngokushushu | Isiseko sesinyithi siyanyibilika kamva |
| Yenziwe ngentsimbi eshayinayo | 1400–1450 | Ukumelana ne-oxidation | Ifestile yewelding ebanzi |
Xa usenza i-capacitor discharge spot welding for galvanized steel, ukufudumeza kombane kwenzeka kwi-interface. Ngenxa yokuba i-coating inyibilika ngaphambi kwesiseko sezinto eziphathekayo, ukugqithisa kwamandla akhoyo okanye ukukhupha amandla kunokunyusa ngokukhawuleza i-coating, ivelise i-spatter kwaye ibangele ilahleko yendawo yokuhlala.
Ubushushu obuveliswe ngexesha lokumelana ne welding ilandela -ubudlelwane obaziwayo:
- Q = I² × R × t
Apho:
- Mna=welding yangoku
- R=ukunganyangeki kombane
- t=ixesha lokuwelda
Ngenxa yokuba imveliso yobushushu inyuka ngokulinganayo kwisikwere sangoku, ukonyusa kwangoku kwitoti{0}}izinto ezifakwe kwisixhobo sokuwelda ngaphandle kokuhlengahlengisa ixesha kunye noxinzelelo kunokudala igalelo lobushushu eligqithileyo, kwandisa kakhulu ingozi yomonakalo wokugquma.
Igalelo loBubushushu obuBabekileyo bukhawulezisa uMngcipheko wokuRhakala
Ukongeza kumaqondo obushushu aphantsi okunyibilika, ubushushu obugqithisileyo ngomnye onegalelo elikhulu kwi-post-i-weld Corrosion, ngakumbi kwindawo yokugcina amandla kunye ne-structural welding applications.
Xa igalelo lobushushu lidlula amanqanaba acetyiswayo, ezi ziphumo zilandelayo ziqhele ukubonwa:
- Indawo yokutshisa ekwandisiweyo
- Ukwanda kokuvezwa kwesiseko sesinyithi
- Ukunciphisa ukhuseleko lomhlwa
- Ukunyuka kwe-oxidation ngexesha lenkonzo
Idatha yokuvelisa ibonisa ukuba xa i-welding yangoku idlula imida ekhuthazwayo malunga15–20%, Umonakalo we-coating unokunyuka ngokuphawulekayo, ngakumbi xa i-current, ixesha, kunye ne-electrode force ingalungiswanga kunye, ngelixa amanqanaba e-spatter nawo aphakama kakhulu. Oku akuchaphazeli inkangeleko ye-weld kuphela kodwa konyusa iindleko zeposi{1}}zokulungisa.
Ubukhulu bengubo buchaphazela kwakhona ifestile ye-welding. Ubukhulu obuqhelekileyo bemali yokwaleka buphakathi5–20 μm, kwaye xa ubukhulu bugqithile15 μm, ukuchaneka okuphezulu kwe-welding kuyadingeka ukugcina iziphumo ezihambelanayo. Kungenxa yoko le ntoUgcino lwamandla eendawo zokuwelda iinkqubo zezixhobo ezigqunyiweyozifuna amandla achanekileyo okulawula amandla.
Yandisa i-Welding Parameters ukuze ulawule ngokuchanekileyo iNgeniso yoBushushu
Kwimathiriyeli ecwecwe, ulawulo oluchanekileyo lokungenisa ubushushu ngoyena mba ubalulekileyo ekuthinteleni ukutsha kwengubo{0}}ngokusebenzisa. Oku kuyinyani ngakumbi kwiigalvanized steel spot welding with capacitor discharge energy storage welders.
Lawula ngokungqongqo ukukhupha amandla kunye ne-Welding yangoku
Kwizinto ezisebenzayo, iiparamitha zewelding kufuneka ziphuhliswe ngokusekelwe kubukhulu bemathiriyeli kunye nohlobo lokwaleka kunokuxhomekeka kulingo-kunye{1}}nohlengahlengiso lwempazamo. Le theyibhile ilandelayo ibonelela ngemilinganiselo yereferensi eqhelekileyo ye-galvanized steel welding.
I-Welding Parameters ezicetyiswayo kwi-Galvanized Steel

A: Ukutsha kokutyabeka{0}kuqhele ukwenzeka xa ubushushu buphezulu kakhulu, ixesha lewelding lilide kakhulu, okanye amandla e-electrode akazinzanga. I-Zinc kunye ne-tin iyanyibilika ngaphambi kwesiseko sentsimbi, ngoko ke amandla okukhutshwa okugqithisileyo anokonakalisa ngokukhawuleza isambatho.
Umbuzo: Ndingawunciphisa njani umhlwa emva kokuwelda ngentsimbi enamabala?
A: Ukunciphisa i-corrosion, lawula igalelo lobushushu, unqande ilahleko eninzi yokwambathisa, i-spatter ecocekileyo emva kwe-welding, kwaye ugcine iindawo ezidityanisiweyo kwindawo eyomileyo. Kwizinto eziphezulu{1} ezithembekileyo, ukhuseleko olongezelelweyo lomphezulu lunokufuneka.
Umbuzo: Ngaba i-capacitor discharge spot welder ifanelekile kwintsimbi ye-galvanized?
A: Ewe. I-capacitor discharge spot welder ingalungela intsimbi kunye nenkcenkce{1}}indawo ezilathiweyo kuba ibonelela{2}}ixesha elifutshane{3}imveliso yangoku kwaye inceda ukulawula ubushushu{4}}indawo echaphazelekayo. Isiphumo sokugqibela sisaxhomekeke kulungiselelo lweparamitha, uyilo lwe-electrode, kunye nemeko yomphezulu.
Q: Yeyiphi imathiriyeli ye-electrode engcono kwi-coated spot welding?
A: Ii-electrode ze-CuCrZr ziqhele ukusetyenziswa kwi-galvanized spot welding kuba zibonelela nge-conductivity elungileyo kunye nokumelana nokunxiba. Ukhetho lokugqibela kufuneka luxhomekeke kuhlobo lokutyabeka, ubukhulu bezinto eziphathekayo, ubungakanani be-weld, kunye nomjikelo wemveliso.
Isiphelo: Lawula i-Heat Input ngaphambi kokuba Umonakalo weCoating Uba yiNgxaki yeMveliso
Ukutshisa i-coating-kunye ne-post-i-weld corrosion kwi-galvanized steel okanye i-tin{2}}i-Plated spot welding ayizoziphene. Kwiimeko ezininzi, zibangelwa kukufakelwa kobushushu obugqithisileyo, amandla e-electrode angazinzanga, ukulungiswa komphezulu okulambathayo, ii-electrode ezigugileyo, okanye ukhuselo olungonelanga lwesithuba{4}}se-weld.
Kwizinto ezigqunyiweyo ezisetyenziswa kwiimodyuli zokugcina amandla, iitheminali, izibiyeli, kunye nezindlu, injongo ayikona nje ukudala i-weld eyomeleleyo. Inkqubo yokuwelda kufuneka ikhusele i-coating kangangoko kunokwenzeka, inciphise isiseko sesinyithi esiveziweyo, kwaye igcine{1}}ixesha elide lokuxhathisa umhlwa.
Xa ukhetha iindawo yokugcina amandla welderokanye i-capacitor discharge spot welder, abathengi kufuneka bagxininise kwimveliso yamandla ezinzileyo, -ulawulo lokukhutshwa kwenqanaba, ulawulo oluchanekileyo loxinzelelo, ukupholisa i-electrode, uyilo lwe-fixture, kunye nenkxaso yesampulu ye-welding. Ezi zinto zinceda ukunciphisa umonakalo wokugquma kunye nokuphucula ukuhambelana kwimveliso ye-batch.
Ukuba iindawo zakho ezigqunyiweyo zifumana ukutsha{0}}nge-spatter, amanqaku amnyama, i-welds ebuthathaka, okanye ukubola emva kogcino, lungisa ubukhulu bemathiriyeli, uhlobo lokugquma, indawo yewelding, iiparamitha zangoku, kunye neefoto ezineziphene phambi kokulungelelanisa inkqubo. Uvavanyo lwe-welding yesampula lunokunceda ukuqinisekisa ukucwangciswa kwezixhobo ezifanelekileyo, isisombululo se-electrode, kunye neeparitha ze-welding kwimveliso ezinzileyo.
