Kwihlabathi le-welding, ukuchaneka kubaluleke kakhulu. Ukuchaswa kwendawo ye-welding akukho nto. Omnye umba obalulekileyo ohlala ungaqatshelwa kodwa udlala indima ebalulekileyo ekuphumezeni iiwelds ezikumgangatho ophezulu lixesha lokulayisha kwangaphambili. Kweli nqaku, siza kuphonononga ukubaluleka kwexesha lokulayisha kwangaphambili koomatshini bokuwelda bamabala.
Qonda
I-Resistance spot welding, indlela yokudibanisa esetyenziswa ngokubanzi kwimizi-mveliso yeemoto, i-aerospace, kunye neyokuvelisa, ibandakanya ukudibanisa amashiti amabini esinyithi kunye kusetyenziswa ukuxhathisa kombane kunye noxinzelelo. Ukufezekisa i-weld eyomeleleyo, ehlala ixesha elide ixhomekeke ekulawuleni iiparamitha ezahlukeneyo, kunye nexesha lokulayisha kwangaphambili lelona libalulekileyo.
Yintoni Ixesha Lokulayisha kwangaphambili?
Ixesha lokulayisha kwangaphambili, kumxholo wokumelana ne-welding spot, ibhekisela kwixesha apho i-electrode icinezelwe kunye namandla ngaphambi kokuba i-welding current isetyenziswe. Lixesha apho amacwecwe amabini esinyithi adibana, kwaye inkqubo yokuwelda iqala.
Kutheni kubalulekile nje ixesha lokulayishwa kwangaphambili?
- Uqhagamshelwano lwezinto eziphathekayo: Ukulayishwa kwangaphambili ngokufanelekileyo kuqinisekisa ukuba amaphepha esinyithi adibene ngokupheleleyo. Olu qhagamshelwano lokuqala lubalulekile kuba naziphi na izikhewu okanye ukungalungelelani kakuhle kunokukhokelela kwiintsimbi ezibuthathaka okanye neziphene zeweld. Amandla asetyenziswa ngexesha lokulayishwa kwangaphambili anceda ukuphelisa ukungafezeki okunjalo.
- Ulawulo lobushushu: Ixesha lokulayishwa kwangaphambili likwanceda ekulawuleni ubushushu bokuqala obuveliswe xa i-welding current isetyenziswa. Ukuba umsinga uqaliswe phambi kokulayishwa kwangaphambili okufanelekileyo, ubushushu obugqithisileyo bunokuphazamisa izixhobo zokusebenza okanye zenze iziphumo ezingathandekiyo zobushushu, kubeke esichengeni umgangatho weweld.
- Ukungqinelana: Ukungaguquguquki ngundoqo kwi-welding spot yokumelana. Ngokuba nexesha elichaziweyo lokulayisha kwangaphambili, abaqhubi banokuphindaphinda iimeko ezifanayo kwi-weld nganye, ukuqinisekisa ukufana kunye nokuthembeka kwinkqubo yokuvelisa.
- I-Electrode Wear: Ukulayisha kwangaphambili okungonelanga kunokukhawulezisa ukunxiba kwe-electrode. Amandla asetyenziswayo ngexesha lokulayisha kwangaphambili anceda ukugcina unxibelelwano lombane olulungileyo phakathi kwee-electrode kunye nezinto zokusebenza, ukunciphisa ukuguga kunye nokwandisa ubomi be-electrode.
- Ukhuseleko: Ixesha elaneleyo lokulayisha kwangaphambili libalulekile kukhuseleko lomsebenzisi. Inciphisa umngcipheko we-electrodes enamathela kwizinto zokusebenza, ezinokubangela ukuba kubekho iimeko ezinobungozi xa uzama ukuhlukana.
Ukulungisa Ixesha lokulayisha kwangaphambili
Ukufezekisa umgangatho we-weld, kubalulekile ukumisela ixesha elifanelekileyo lokulayisha kwangaphambili kwizinto ezithile kunye neemeko ze-welding. Izinto ezinje ngodidi lwemathiriyeli, ubukhulu, kunye neepropathi ezinqwenelekayo ze-weld zonke zinefuthe elona xesha lifanelekileyo lokulayisha. Abavelisi bahlala beqhuba uvavanyo olubanzi kunye nokulinga ukuseka ezona zenzo zilungileyo zezicelo zabo.
Ukuqukumbela, ngelixa ukulayisha kwangaphambili kunokubonakala ngathi yinkcukacha encinci kwi-weld spot yokumelana, yinto, eneneni, yinto esisiseko enokwenza okanye yophule umgangatho we weld. Ukuqinisekisa ixesha elililo lokulayisha kwangaphambili akuphumeleli nje kuphela kukuqina, iiwelds ezithembeke ngakumbi kodwa konyusa ukhuseleko kunye nokusebenza kakuhle kwinkqubo ye-welding. Sisikhumbuzo sokuba kwihlabathi le-welding echanekileyo, umzuzu ngamnye ubalulekile.
