Iyini i-Fusion Nugget?Inqubo ye-Fusion Nugget Formation ku-Medium-Frequency Inverter Spot Welding

Enqubweni ye-medium-frequency inverter spot welding, ukwakheka kwe-fusion nugget kudlala indima ebalulekile ekuzuzeni ukushisela okuqinile nokuthembekile.Lesi sihloko sihlose ukuchaza umqondo we-fusion nugget futhi sijule enqubweni yokwakheka kwayo ku-medium-frequency inverter spot welding.

1. I-Fusion Nugget: I-fusion nugget ibhekisela endaweni eyenziwe yasendaweni yezinto ezincibilikisiwe ezakha phakathi nenqubo yokushisela.Kungumphumela wokushisa okukhulu okukhiqizwa ukumelana kukagesi phakathi kwezinto zokusebenza kanye ne-welding current esetshenziswayo.I-fusion nugget inesibopho sokuhlanganisa ama-workpieces ndawonye, ​​​​ukwakha ijoyinti le-weld eliqinile neliqinile.
2. Inqubo ye-Fusion Nugget Formation: Ukwakhiwa kwe-fusion nugget ku-medium-frequency inverter spot welding kuhilela izigaba ezimbalwa:

a.Ukuthintana Nokucindezelwa: Izinto zokusebenza ezizoshiselwa zihlanganiswa futhi zicindezelwe ndawonye ngamandla e-electrode.Lokhu kuqinisekisa ukuthintana okusondelene futhi kusungula indlela yokuhambisa ye-welding current.

b.Ukushisisa: Uma ama-workpieces esexhumene, i-welding current ephezulu idlula kuwo.Ukumelana nogesi kusixhumi esibonakalayo kudala ukushisa, kukhuphule izinga lokushisa ngokushesha endaweni yokuxhumana.Ukushisa kubangela ukuthi izinto zithambe futhi ekugcineni zincibilike, kwakheka ichibi elincibilikisiwe.

c.Ukuxuba kanye Nokuqinisa: Njengoba i-welding current iqhubeka nokugeleza, izinto ezincibilikisiwe ezivela kuzo zombili izinto zokusebenza zihlangana ndawonye echibini elincibilikisiwe.Lokhu kukhuthaza ukusakazeka kwama-athomu futhi kusiza ukwakheka kwezibopho ze-metallurgical phakathi kwezinto zokusebenza.Ichibi elincibilikisiwe libe seliqala ukuqina njengoba ukushisa kuncipha, kwakheka i-fusion nugget.

d.Ukupholisa kanye Nokuqinisa: Ngemva kokuba i-welding current ivaliwe, i-fusion nugget iqala ukuphola futhi iqine.Izinga lokupholisa lithinta i-microstructure kanye nezakhiwo zemishini ze-weld.Ukupholisa okulawulwayo kuvumela ukwakheka kwezigaba ze-metallurgical oyifunayo futhi kuqinisekisa amandla afanele we-weld.

3. Izinto Ezithonya Ukwakhiwa Kwe-Fusion Nugget: Izinto ezimbalwa zingathonya ukwakheka kwe-fusion nugget ku-medium-frequency inverter spot welding:

• I-Welding current: Ubukhulu be-welding current buthinta ngokuqondile isizukulwane sokushisa futhi, ngenxa yalokho, ubukhulu nokujula kwe-fusion nugget.
• Amandla e-Electrode: Ingcindezi esetshenzisiwe inquma indawo yokuxhumana phakathi kwezinto zokusebenza, okuthinta ukusatshalaliswa kokushisa nokwakheka kwe-nugget.
• Isikhathi sokushisela: Ubude benqubo yokushisela buthinta inani lokufaka ukushisa kanye nosayizi we-fusion nugget.
• Izakhiwo zezinto ezibonakalayo: I-conductivity, ukujiya, kanye nokwakheka kwezinto zokusebenza kuthonya ukumelana kwazo nokugeleza kwamanje futhi, ngenxa yalokho, ukukhiqizwa kokushisa nokwakheka kwe-nugget ye-fusion.

I-fusion nugget iyingxenye ebalulekile ekuzuzeni ukushisela okuphumelelayo ekushiseleleni kwendawo ye-inverter ye-medium-frequency.Ukuqonda inqubo yokwakheka kwe-fusion nugget kanye nezici eziyithonya kungasiza ekuthuthukiseni amapharamitha wokushisela, ukulawula ikhwalithi yokushisela, nokuqinisekisa amandla nokuqina kwejoyinti lokushisela.Ngokuphatha ngokucophelela i-welding current, amandla e-electrode, isikhathi sokushisela, kanye nezakhiwo zezinto ezibonakalayo, abashiseli bangakwazi ukufeza ukwakheka okungaguquki nokuthembekile kwe-fusion nugget, okuholela ekushiselweni kwendawo okuphezulu.
