Iimeko zokuwelda kunye neenkcukacha zizinto ezibaluleke kakhulu ekufezekiseni ukuwelda okuthembekileyo kunye nomgangatho ophezulu kwindawo ephakathi frequency inverter indawo oomatshini welding. Eli nqaku linika inkcazo yeemeko ze-welding kunye neenkcukacha ezifunekayo ukuba zithathelwe ingqalelo kwimisebenzi ye-spot welding eyimpumelelo.
- Iimeko zeWelding: Iimeko ezifanelekileyo ze-welding ziqinisekisa ukudityaniswa okufunwayo, amandla, kunye nokuthembeka kweendawo zokuwelda. Imiba ephambili yeemeko ze-welding ziquka:
- Iisetingi zangoku kunye ne-voltage: Ukumisela amaxabiso afanelekileyo ngokusekwe kuhlobo lwemathiriyeli, ubukhulu, kunye neemfuno ezidibeneyo.
- Ixesha le-Welding: Ukubeka ixesha lokuhamba kwe-welding yangoku ukufezekisa igalelo elaneleyo lokushisa kunye nokungena ngokufanelekileyo.
- Amandla e-Electrode: Ukusebenzisa uxinzelelo olufanelekileyo ukuqinisekisa uqhagamshelwano olulungileyo kunye nokuguqulwa okufanelekileyo ngaphandle kokwenza umonakalo.
- Ixesha lokupholisa: Ukuvumela ixesha elaneleyo lokuba i-weld iphole kwaye iqine ngaphambi kokususa uxinzelelo.
- Iinkcazo ze-Welding: Iimpawu ze-Welding zibonelela ngezikhokelo kunye nemigangatho yokufezekisa i-welds yendawo ehambelanayo kunye nethembekileyo. Iingqwalasela ezibalulekileyo malunga neenkcukacha ze-welding ziquka:
- Ukuhambelana kwezinto: Ukuqinisekisa ukuba izinto ezisisiseko kunye nezixhobo ze-electrode zifanelekile kwisicelo esijoliswe kuyo.
- Uyilo oludityanisiweyo: Ukulandela ulungelelwaniso olukhankanyiweyo oludibeneyo, kubandakanywa ubude be-overlap, umgama we-gap, kunye nokulungiswa komphetho.
- Ubungakanani be-weld kunye nesithuba: Ukubambelela kwidayamitha ye-weld nugget echaziweyo, i-pitch, kunye neemfuno zezithuba.
- Iinqobo zokwamkelwa: Ukuchaza imilinganiselo yomgangatho wokuvavanya i-welds, njengobungakanani obamkelekileyo be-nugget, iziphene ezibonakalayo, kunye neemfuno zamandla.
- Inkqubo ye-Welding: Inkqubo ye-welding echazwe kakuhle ibalulekile ekugcineni ukuhambelana kunye nomgangatho kwi-welding spot. Inkqubo ye-welding kufuneka ibandakanye:
- Ukulungiswa kwangaphambili kwe-weld: Ukucoca umphezulu, ukubeka izinto eziphathekayo, kunye nokulungelelaniswa kwe-electrode.
- Ukulandelelana kwemisebenzi: Amanyathelo achazwe ngokucacileyo okubekwa kwe-electrode, ukusetyenziswa kwangoku, ukupholisa, kunye nokususwa kwe-electrode.
- Amanyathelo okulawula umgangatho: Iindlela zokuhlola, uvavanyo olungonakalisi, kunye namaxwebhu eeparamitha ze-welding.
- Ukuthotyelwa kweMigangatho kunye neMimiselo: Oomatshini be-welding spot welding kufuneka bahambelane nemigangatho efanelekileyo kunye nemigaqo yokhuseleko. Oku kunokubandakanya:
- Imigangatho yamazwe ngamazwe: ISO 18278 yokuwelda indawo yemoto, i-AWS D8.9 yokuwelda indawo ye-aerospace, njl.
- Imigaqo yokhuseleko yasekhaya: Ukuthotyelwa kokhuseleko lombane, ukugada koomatshini, kunye neemfuno zokusingqongileyo.
Ukubambelela kwiimeko ezifanelekileyo ze-welding kunye neenkcukacha kubalulekile ekufezekiseni ukungaguquguquki, okuthembekileyo, kunye nomgangatho ophezulu we-welds kwi-medium frequency inverter spot welding machines. Ngokuqwalasela ngenyameko izinto ezifana ne-welding current, ixesha, amandla e-electrode, kunye nokupholisa, abaqhubi banokuqinisekisa ukudibanisa okufanelekileyo, amandla adibeneyo kunye nokunyaniseka kwemilinganiselo. Ukulandela imigaqo ye-welding kunye neenkqubo, kunye nokuthobela imigangatho esebenzayo kunye nemimiselo, iqinisekisa umgangatho ofunekayo we-weld kwaye ixhasa impumelelo yonke yemisebenzi ye-welding.
