Amapharamitha wesikhathi kumishini yokushisela i-Nut Spot?

Imishini yokushisela yamantongomane isebenzisa imingcele yesikhathi ehlukahlukene ukuze ilawule futhi yandise inqubo yokushisela. Lawa mapharamitha esikhathi adlala indima ebalulekile ekunqumeni ubude besikhathi nokulandelana kwezigaba ezithile zokushisela, ukuqinisekisa ukukhiqizwa kokushisela kwekhwalithi ephezulu. Lesi sihloko sinikeza ukubuka kabanzi kwemingcele yesikhathi ebalulekile esetshenziswa emishinini yokushisela amantongomane.

1. Isikhathi sangaphambi kokushisela: Isikhathi sangaphambi kokushisela sisho ubude besikhathi ngaphambi kokuqala kwenqubo yokushisela. Ngalesi sikhathi, ama-electrode ahlanganiswa nendawo yokusebenza, esebenzisa ingcindezi yokusungula ukuthintana kahle kukagesi. Isikhathi sangaphambi kokushisela sivumela ukuhlanganiswa kwelunga kanye nokususwa kwanoma yikuphi ukungcola okungaphezulu noma izendlalelo ze-oxide.
2. Isikhathi sokushisela: Isikhathi sokushisela simelela ubude besikhathi lapho i-welding yamanje igeleza ngama-electrode, okwenza i-weld nugget. Isikhathi sokushisela silawulwa ngokucophelela ukuze kuzuzwe okokufaka okushisa okufunayo kanye nokuhlanganisa phakathi kwamantongomane nezinto zokusebenza. Kuncike ezintweni ezifana nobukhulu bezinto ezibonakalayo, ukwakheka okuhlanganyelwe, namandla okushisela afiswayo.
3. Isikhathi se-Post-Weld: Ngemva kokuba i-welding current ivaliwe, isikhathi se-post-weld sibhekisela esikhathini lapho ingcindezi igcinwa khona ekuhlanganyeleni ukuze kuvunyelwe ukuqina nokupholisa kwe-weld. Le parameter yesikhathi iqinisekisa ukuthi i-weld iqina ngokwanele ngaphambi kokukhulula ukucindezela. Isikhathi se-post-weld singahluka kuye ngezinto ezibonakalayo kanye nezidingo ezihlangene.
4. Isikhathi se-Inter-Weld: Kwezinye izinhlelo zokusebenza lapho ukushisela okuningi kwenziwa ngokulandelana, isikhathi se-inter-weld singeniswa phakathi kokushisela okulandelanayo. Lesi sikhawu sesikhathi sivumela ukuchithwa kokushisa, ukuvimbela ukunqwabelana kokushisa okudlulele kanye nokulimala okungaba khona kuma-electrode noma ucezu lokusebenza. Isikhathi se-inter-weld sibalulekile ekugcineni izimo zokushisela ezingaguquki kuyo yonke inqubo yokukhiqiza.
5. I-off-Time: I-off-time imelela ubude besikhathi phakathi kokuqedwa komjikelezo owodwa wokushisela kanye nokuqaliswa kolandelayo. Ivumela ukumiswa kabusha kwe-electrode, ukubekwa kabusha kwe-workpiece, noma noma yiziphi izinguquko ezidingekayo ngaphambi kokuqala umsebenzi wokushisela olandelayo. I-off-time ibalulekile ekuqinisekiseni ukuhamba komsebenzi okufanele kanye nokuhambisana phakathi kwama-electrode kanye ne-workpiece.
6. Isikhathi Sokukhama: Isikhathi sokuminyanisa sibhekisela esikhathini lapho ingcindezi ifakwa esihlanganyelwe ngaphambi kokuba kuqaliswe umshini wokushisela. Lesi sikhathi sepharamitha siqinisekisa ukuthi ama-electrode abamba ngokuqinile isiqeshana sokusebenza futhi asungule ukuthintana kukagesi okulungile. Isikhathi sokuminyanisa sivumela ukususwa kwanoma yiziphi izikhala zomoya noma ukungalungi kwendawo, okuthuthukisa ikhwalithi yokushisela engaguquki.

Imingcele yesikhathi idlala indima ebalulekile ekulawuleni inqubo yokushisela indawo yamantongomane kanye nokuzuza ukushisela kwekhwalithi ephezulu. Isikhathi sangaphambi kokushisela, isikhathi sokushisela, isikhathi sangemva kokushisela, isikhathi sokushisela, isikhathi sokuphumula, nesikhathi sokuminyanisa kuphakathi kwemingcele yesikhathi ebalulekile esetshenziswa emishinini yokushisela amantongomane. Ukulungiswa okufanele kanye nokwenza kahle kwalezi zinhlaka zesikhathi kuqinisekisa imiphumela ethembekile futhi engaguquki yokushisela, kucatshangelwa izici ezifana nokuklama okuhlangene, izakhiwo zezinto ezibonakalayo, nezici zokushisela ezifiselekayo. Ukuqonda nokuphatha ngempumelelo le mingcele yesikhathi kunomthelela ekusebenzeni kahle kanye nekhwalithi yenqubo yokushisela amantongomane.
