Ezweni lokushisela, ukunemba kubaluleke kakhulu.I-Resistance spot welding nayo ihlukile.Isici esisodwa esibalulekile esivame ukunganakwa kodwa esidlala indima ebalulekile ekuzuzeni amashisela ekhwalithi ephezulu isikhathi sokulayisha kuqala.Kulesi sihloko, sizocubungula ukubaluleka kwesikhathi sokulayisha ngaphambili emishinini yokushisela indawo yokumelana.
Qonda
I-Resistance spot welding, indlela yokuhlanganisa esetshenziswa kakhulu ezimbonini zezimoto, i-aerospace, neyokukhiqiza, ihlanganisa ukuhlanganisa amashidi ensimbi amabili ndawonye kusetshenziswa ukumelana nogesi nokucindezela.Ukuzuza ukushisela okuqinile, okuqinile kuncike ekulawuleni amapharamitha ahlukahlukene, ngesikhathi sokulayisha kuqala esingesinye sezibaluleke kakhulu.
Siyini Isikhathi Sokulayisha ngaphambilini?
Isikhathi sokulayisha ngaphambili, esimweni sokushisela indawo yokumelana, sibhekisela esikhathini lapho ama-electrode ecindezelwa ndawonye ngamandla ngaphambi kokuba kusetshenziswe i-welding current.Yisikhathi lapho amashidi ensimbi amabili ehlangana khona, futhi inqubo yokushisela iqala.
Kungani Sibalulekile Isikhathi Sokulayisha Ngaphambili?
- Ukuxhumana Okubalulekile: Ukulayisha kuqala okufanele kuqinisekisa ukuthi amashidi ensimbi axhumene ngokugcwele.Lokhu kuthintana kokuqala kubalulekile ngoba noma yiziphi izikhala noma ukungahambi kahle kungaholela ekushiseleleni okubuthakathaka noma ngisho nezici zokushisela.Amandla asetshenziswa ngesikhathi sokulayisha ngaphambili asiza ukuqeda ukungapheleli okunjalo.
- Ukulawula Okushisayo: Isikhathi sokulayisha ngaphambili siphinde sisize ekulawuleni ukushisa kokuqala okukhiqizwa lapho kusetshenziswa i-welding current.Uma i-curse iqaliswa ngaphambi kokulayisha kusengaphambili okufanele, ukushisa okudlulele kungahlanekezela izinto zokusebenza noma kudale imiphumela engathandeki yokushisa, okonakalise ikhwalithi ye-weld.
- Ukuvumelana: Ukungaguquguquki kuyisihluthulelo ku-resistance spot welding.Ngokuba nesikhathi esichaziwe sokulayisha ngaphambili, opharetha bangaphinda izimo ezifanayo kuwo wonke ama-weld, baqinisekise ukufana nokuthembeka enqubweni yokukhiqiza.
- I-Electrode Wear: Ukulayisha kuqala okunganele kungasheshisa ukugqokwa kwama-electrode.Amandla asetshenziswa ngesikhathi sokulayisha ngaphambili asiza ukugcina ukuxhumana okuhle kukagesi phakathi kwama-electrode nezinto zokusebenza, kwehlise ukuguga nokwelula ukuphila kwama-electrode.
- Ukuphepha: Isikhathi esanele sokulayisha ngaphambili sibalulekile ekuphepheni komqhubi.Inciphisa ubungozi bokuthi ama-electrode anamathele ezintweni zokusebenza, okungaholela ezimweni eziyingozi uma uzama ukuzihlukanisa.
Ukulungiselela Isikhathi Sokulayisha ngaphambilini
Ukuze uthole ikhwalithi ephezulu yokushisela, kubalulekile ukunquma isikhathi esifanele sokulayisha kuqala sezinto ezithile nezimo zokushisela.Izinto ezifana nohlobo lwempahla, ukujiya, kanye nezakhiwo zokushisela ezifiselekayo zonke zithonya isikhathi esifanele sokulayisha kuqala.Abakhiqizi bavamise ukwenza ukuhlola okubanzi nokuhlola ukuze bathole izinqubo ezingcono kakhulu zezinhlelo zabo zokusebenza ezithile.
Sengiphetha, nakuba isikhathi sokulayisha kuqala singase sibonakale njengemininingwane emincane ekushiseleleni indawo yokumelana, empeleni, into eyisisekelo engenza noma yephule ikhwalithi ye-weld.Ukuqinisekisa isikhathi esifanele sokulayisha ngaphambili akuphumeleli nje kuphela ekushiseleni okuqinile, okuthembeke kakhulu kodwa futhi kuthuthukisa ukuphepha nokusebenza kahle enqubweni yokushisela.Kuyisikhumbuzo sokuthi emhlabeni wokushisela ngokunemba, sonke isikhathi sibalulekile.
