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 ye-weld. Ukupholisa okulawulwayo kuvumela ukwakheka kwezigaba ze-metallurgical ezifunwayo 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.
