Intsimbi engatyiwayo ixatyiswe kakhulu ngenxa yokuxhathisa okugqwesileyo kokutya kunye neempawu zoomatshini, ukanti iimpawu zayo ezizodwa zinika imicelimngeni ecacileyo yokuwelda. Ubuchwephesha obungalunganga bunokukhokelela ekungoneli kwe-weld nugget amandla, i-oxidation yomhlaba, kunye nokuguqulwa kwezinto.
Esi sikhokelo sibonelela ngendlela ecwangcisiweyo yokulawula ukuwelda kwentsimbi engenakutyiwa, siqinisekisa ukuba yonke intsimbi iphumeza ubungcali,-umgangatho ophezulu womgangatho ngezixhobo eziphuculweyo, ulungelelwaniso oluchanekileyo lweparamitha, kunye neenkqubo ezisemgangathweni.
I. ULungiselelo olungundoqo: Ukusukela ukuGqwesa kwiZixhobo kunye ne-Electrodes
I-weld eyimpumelelo iqala ngokulungiselela ngononophelo. Insimbi engenasici inomdla ngokukodwa kwimeko yezixhobo kunye nokukhethwa kwee-electrodes, apho nakuphi na ukongamela kunokuphazamisa umgangatho wokugqibela.
1.Spot Ukuhlolwa kweWelder kunye noLondolozo
- Amandla kunye nokuBeka: Phambi kokuqaliswa kwemihla ngemihla, zihlole ngocoselelo iintambo zombane kunye noqhagamshelo olusezantsi lokhuseleko, uqinisekise ukuba akukho monakalo okanye ukukhululeka. Ubonelelo lwamandla oluzinzileyo lubalulekile ekuhambiseni imisinga yokuwelda echanekileyo.
- Uvavanyo lwe-Insulation Resistance: Ngamaxesha athile (umzekelo, ngenyanga), sebenzisa i-megohmmeter ukuvavanya ukuxhatshazwa komatshini wokukhusela, uqinisekise ukuba uhlala ungaphezulu kwe-2.5 MΩ. Esi senzo sithintela ngokufanelekileyo ukuvuza kombane kunye neengozi ezimfutshane{4} zesekethe, iqinisekisa ukhuseleko lokusebenza.
- Inkqubo yokupholisa "yiNtliziyo": Ubushushu obugxininisiweyo kwi-welding yensimbi engenasici yenza ukupholisa okusebenzayo kubaluleke kakhulu.
- Ubushushu baManzi ekungeneni: Gcina ubushushu bokungena kwamanzi okupholisa phakathi kwe-5-30℃(41-86℃F). Amaqondo obushushu aphezulu kakhulu amanzi aya kunciphisa kakhulu ukusebenza kakuhle kokupholisa.
- Ubushushu boMoya obuphumayo: Qhubeka ubeka iliso kwiqondo lokushisa lomoya lokuphuma, ekufuneka ligcinwe ngaphantsi kwe-40℃(104 degrees F). Ukunyuka okungaqhelekanga kokushisa kuphawu olucacileyo lomgca wamanzi ovaliweyo okanye ukuhamba okunganeleyo, okudinga ukuvalwa ngokukhawuleza ukuze kuhlolwe.
2.Ukhetho lwe-Electrode, Ukunxiba, kunye noLondolozo
I-electrode, ehambisa zombini ngoku kunye noxinzelelo, ichaza ngokuthe ngqo ukubunjwa kwe-weld nugget.
- Izinto ezikhethwayo ze-Electrode: Kwinsimbi engenasici, iChromium Zirconium Copper (Cr{0}}Zr-Cu) yinto ekhethwayo ye-electrode. Le ngxubevange igcina ubulukhuni obugqwesileyo kunye nokuhanjiswa kumaqondo obushushu aphezulu kwaye ayithandeki kakhulu ukuncamathela kwisixhobo sokusebenza sentsimbi.
- Electrode Tip Ukunxiba: I-electrode tip iya kunxiba ngokuthe ngcembe kwaye iguqule (into eyaziwa ngokuba yi "mushrooming") ngexesha le-welding. Xa ubukhulu bayo bukhula ngaphezu20%okanye i-pitting ebalulekileyo iyenzeka, kufuneka inxibe ngokukhawuleza ngesixhobo esikhethekileyo okanye itshintshwe. Ukungaphumeleli ukwenza oko kuya kunciphisa ukuxinana kwangoku kwaye kubangele ukomelela okungafanelekanga kwe-weld.
- Gcina Ucocekile: Emva komjikelezo we-welding ngamnye, i-microscopic oxides okanye i-spatter inokubambelela kwindawo ye-electrode. Sula rhoqo iingcebiso ngelaphu elicocekileyo le-emery okanye isixhobo esizinikezeleyo sokucoca ukukhusela ukungcoliseka komsebenzi kunye nokuqinisekisa ukuxhathisa okuzinzile.
II. IParameter Optionation: Isitshixo kwi-Weld egqibeleleyo
Uqwalaselo oluchanekileyo lweparameter ngumphefumlo wentsimbi yestainless spot welding. Iiparameters ezingundoqo-zangoku, ixesha, kunye noxinzelelo{2}}kufuneka zilungelelaniswe kakuhle ukuze ufumane iziphumo ezizezona. Itheyibhile engezantsi ishwankathela uluhlu olucetyiswayo lweparamitha kunye neengqwalaselo eziphambili kwiingqimba ezahlukeneyo zentsimbi.
IiParameters eziCetyisiweyo zeStainless Steel Spot Welding
| Uluhlu lweParameter | IParameter engundoqo | AMashiti amancinci (0.5mm - 1.5mm) | AMashiti atyebileyo (1.5mm - 3.0mm) | Iingqwalasela eziPhambili kunye neeNgcebiso zokuSebenza |
| Ngoku kunye nexesha | I-Welding yangoku (kA) | 6 - 10 kA | 10 - 15 kA (okanye ngaphezulu) | Umgaqo: Landela "ishedyuli enzima" (ixesha eliphezulu, ixesha elifutshane) ukunciphisa ubushushu-indawo echaphazelekayo (HAZ) kunye nokugqwetheka. |
| Ixesha le-Weld (ms) | 10 - 100 ms | 80 - 200 ms | Ukuphucula: Amaxesha amafutshane akhokelela kwi-oxidation encinci. -Ingoma entle esekwe kwiziphumo zovavanyo lwamandla e-weld. | |
| Isicwangciso-qhinga sokuSebenza | Beka phambili "ishedyuli enzima" ukwenza i-nugget ngokukhawuleza kwaye uthintele ukutshisa. | Kusenjalo ngokuyintloko "ishedyuli enzima," kodwa qinisekisa ukuba okwangoku kungene ngokupheleleyo; ixesha linokolulwa kancinane. | Qaphela: Kwizinto eziphathekayo ezineemfuno eziphezulu ze-cosmetic, "ishedyuli ethambileyo" (ixesha eliphantsi langoku, ixesha elide) inokuzanywa, kodwa ifuna ukulawulwa kakuhle ukukhusela ukushisa. | |
| Uxinzelelo | Uxinzelelo lweWeld (MPa) | 0.3 - 0.5 iMPa | 0.5 - 0.8 iMPa | Umsebenzi: Iqinisekisa unxibelelwano olusondeleyo phakathi kwezinto zokusebenza, yoyisa ukuqina kwesixhobo kumaqondo obushushu aphezulu, kwaye icinezela ukugxothwa (i-spatter). |
| Cwitsa/Bamba Ixesha | Ixesha elide ngokwaneleyo ukuzinzisa i-workpiece. | Ixesha elide ngokwaneleyo ukuzinzisa i-workpiece. | Umgaqo: Uxinzelelo kufuneka lusetyenziswe phambi kwangoku (Ixesha lokuCwangcisa) kwaye ligcinwe emva (Ukubamba ixesha) ukuvumela ukuqina okufanelekileyo kwe-nugget. | |
| Adjustment Advice | Uxinzelelo oluncinci kakhulu lubangela ukugxothwa kunye neziphene zangaphakathi; kakhulu kubangela ukufakwa ngokugqithisileyo kwaye kukhawulezise ukunxiba kwe-electrode. | Qala ngamaxabiso acetyiswayo kunye -yengoma entle esekwe kubunzulu bokwenyani kunye nokugxothwa. | Khangela: Ubunzulu be-weld indentation kufuneka bungadluli kwi-10-15% yobuninzi bezinto eziphathekayo. | |
| Inkqubo yokuqinisekisa | UHlolo Olubonwayo | I-Nugget kufuneka ibe yisilivere{0}emhlophe okanye emthubi okhanyayo kunye neyunifomu, ukuhlehlisa kancinci. | Umbala weNugget kunye ne-indentation kufuneka ihlale ihambelana. | Isilumkiso: Ibhulowu elimnyama, elimfusa, okanye elimnyama libonisa ukushisa okugqithisileyo kunye ne-oxidation. Ngokukhawuleza ukunciphisa okwangoku okanye unciphise ixesha le-weld. |
| Uvavanyo lwamandla | Yenza uvavanyo lwe-peel, olufanele lubangele "i-nugget pullout" okanye "iqhosha." | Yenza uvavanyo lwe-peel okanye i-shear ukuqinisekisa ukuba amandla e-weld adibana neenkcukacha zoyilo. | Umgangatho: I-diameter ye "iqhosha" elitsaliweyo kufuneka ubuncinane libe yi-80% ye-weld nugget diameter, ebonisa ukudibanisa okulungileyo kunye nokusetyenziswa ngokupheleleyo kwamandla esiseko sesinyithi. |
Amanqaku osetyenziso:
- Isiqalo, Hayi Isiphelo: Le theyibhile inika indawo yokuqala ethembekileyo. Iiparamitha ezifanelekileyo ziya kwahluka ngokusekelwe kwimodeli ye-welder ethile, imeko ye-electrode, kunye nebakala lensimbi engenasici (umz., 304, 316).
- Uhlengahlengiso olucwangcisiweyo: Xa ulungisa iiparamitha, kuyacetyiswa ukuba utshintshe enye kuphela ngexesha (umzekelo, lungisa okwangoku kuqala, emva koko ixesha) ukujonga isiphumo salo kwisiphumo se-weld.
- Yakha iDatabase: Kucetyiswa kakhulu ukuba wenze "iKhadi leShedyuli ye-Weld" eqinisekisiweyo kwindibaniselwano yemathiriyeli nganye osoloko uyiqhuba, ubhala iiparamitha ezifanelekileyo zokwakha isiseko sedatha esisemgangathweni seworkshop yakho.
