Kungani I-Induction Preheating Ibalulekile Ekushiseleni: Izinzuzo Namasu.
I-Induction preheating inqubo lapho into eqhutshwa ngogesi ishisiswa ngokufaka umsinga kagesi kuyo. Ukushisa kukhiqizwa ukuphikiswa kwezinto ekugelezeni kwamanje. I-Induction preheating isetshenziswa kabanzi embonini yokushisela ukuthuthukisa ikhwalithi yama-welds. Leli phepha lihlola izinzuzo zokushisisa kokungeniswa ngaphambi kokushisela, inqubo ehilelekile, kanye nomthelela onalo ekuhlanganyeleni okushiselwe.
Izinzuzo induction preheating ngaphambi kokushisela
Ukushisa kwe-induction kunikeza izinzuzo eziningi, kufaka phakathi:
1. Ukukhululeka Kwingcindezi
Ukushisa kwe-induction kunciphisa ingcindezi esele ekuhlanganyeleni kwe-weld ngokwandisa izinto eziyisisekelo ngaphambi kokushisela. Njengoba impahla ishisa, iyanwebeka, futhi lapho iphola, iyafinyela. Lokhu kwandiswa nokufinyela kunciphisa ingcindezi esele ekuhlanganyeleni okushiselayo, okuholela ekuhlanganyeleni okuqinile futhi okuhlala isikhathi eside.
2. Ikhwalithi Ye-Weld Ethuthukisiwe
Ukushisa kwe-induction kusiza ukuthuthukisa ikhwalithi ye-weld ngokunciphisa amathuba okuba ne-porosity nokuqhekeka. Inqubo inciphisa inani le-hydrogen ku-weld pool, inciphisa ingozi ye-porosity. Ukwengeza, inqubo yokushisa isiza ukuthuthukisa ukuhlanganiswa kwe-weld, iyenze ibe namandla futhi ihlale isikhathi eside.
3. Ukwengeza Ukuphumelela
Ukushisa kwe-induction kukhulisa ukusebenza kahle kwenqubo yokushisela ngokwenza ngcono ukusatshalaliswa kokushisa endaweni yokusebenza. Inqubo iqinisekisa ukuthi ukushisa kusatshalaliswa ngokulinganayo, kunciphisa isikhathi sokushisela nokuthuthukisa ukukhiqiza jikelele.
Inqubo ye-Induction Preheating ngaphambi kwe-Welding
Inqubo ye-induction preheating ngaphambi kwe-welding ibandakanya lezi zinyathelo ezilandelayo:
1.Ungakhetha kanjani i-heater yokungeniswa efanele yephrojekthi yakho yokushisela
Ngenkathi ukhetha i-heater yokungeniswa yephrojekthi yakho yokushisela, kunezici eziningi okufanele uzicabangele. Okokuqala, udinga ukunquma usayizi we-heater oyidingayo. Lokhu kuzoncika kusayizi nogqinsi lwensimbi oyishiselayo. 
Kufanele futhi uqinisekise ukuthi i-heater iyahambisana nohlobo lwensimbi osebenza ngayo. Izinsimbi ezihlukene zinezindawo zokuncibilika ezihlukene, ngakho-ke kubalulekile ukukhetha i-heater ekwazi ukumelana nokushisa okudingekayo. Ukwengeza, kufanele ucabangele uhlobo lomthombo wamandla i-heater edingayo, kanye nezindleko zokuyisebenzisa. Amanye ama-heaters angenayo adinga amandla amaningi futhi angabiza ukuwaqhuba, ngakho-ke kubalulekile ukucabangela lezi zici ngaphambi kokuthenga. Okokugcina, kufanele ucabangele uhlobo kanye nesithunzi somkhiqizi. Ufuna ukwenza isiqiniseko sokuthi uthenga i-heater yekhwalithi ephezulu eyakhelwe ukuthi ihlale isikhathi eside. Ngokucabangela lezi zici, ungakhetha i-heater yokungeniswa efanele yephrojekthi yakho yokushisela futhi uqinisekise ukuthi iphrojekthi yakho iyimpumelelo.
2. Ukubeka Ucwecwe
Isinyathelo esilandelayo ukubeka isiqeshana somsebenzi ngendlela efanele. I-workpiece kufanele ibekwe ukuze ikhoyili ye-induction ibekwe eduze nendawo yokushisela.
3. Ukusebenzisa Ikhoyili Yokungeniswa
The coil induction bese isetshenziswa kucezu lokusebenza, futhi i-AC ye-high-frequency current idluliswa kuyo. Njengoba i-current idlula ku-workpiece, iyayishisa, iyishise ngaphambili ngaphambi kokushisela.
4. Ukushisa
Lapho i-workpiece isishisiwe, inqubo yokushisela ingaqala. Izinto ezishisiwe zinciphisa okokufaka ukushisa kanye nesikhathi se-welding, okuholela ekuhlanganyeleni okunamandla futhi okuhlala isikhathi eside.
Umthelela we-Induction Preheating on the Welded Joint
Ukukhipha ukushisa kunomthelela omkhulu ekuhlanganyeleni okushiselwe. Inqubo yokushisa inciphisa ukucindezeleka okusele ekuhlanganyeleni futhi ithuthukise ikhwalithi ye-weld. Ukuguqulwa kwesakhiwo sensimbi ngemva kokushisa kwangaphambili kuholela ekunciphiseni ukuqina endaweni ethinteke ukushisa (HAZ). Sekukonke, inqubo yokushisa ngaphambili iholela ekuthuthukisweni kwekhwalithi ye-weld nokuqina. 
Izinhlobo zezifudumezi zokungeniswa zokushisa kuqala
Nakuba isihloko sokuba yindoda engcono sibanzi, kubalulekile ukugxila ezinyathelweni zoguquko ezingathathwa ukuze kufezwe lo mgomo. Isinyathelo esisodwa esingathathwa ukutshala imali kumathuluzi ekhwalithi ephezulu angakusiza ohambweni lwakho. Izifudumezi zokungeniswa ziyithuluzi elinjalo elingaba usizo ngendlela emangalisayo, ikakhulukazi uma kuziwa ezintweni zokushisa kwangaphambili. Kunezinhlobo eziningana ezahlukene zezifudumezi zokungeniswa ezitholakalayo, ngayinye enezinzuzo zayo ezihlukile. Isibonelo, amanye ama-heaters aklanyelwe ukuthi aphatheke futhi kube lula ukuhambahamba, kanti amanye amile futhi aklanyelwe ukusetshenziswa esitolo noma egaraji. Ngokufanayo, ezinye izifudumezi zokungeniswa zenzelwe ukusetshenziswa ngezinto ezincane, kanti ezinye zinamandla futhi zingasetshenziswa ngezinto ezinkulu. Uma ukhetha i-heater yokufaka ukushisa ngaphambi kokushisa, kubalulekile ukucabangela izidingo zakho ezithile bese ukhetha imodeli eklanyelwe ukuhlangabezana nalezo zidingo. Ngethuluzi elilungile esandleni sakho, ungathatha isinyathelo sokuqala sokuguqula ukuze ube yindoda engcono.
Isiphetho
Ukushisa kwe-induction ngaphambi kwe-welding kuyinqubo ebalulekile embonini yokushisela. Le nqubo inezinzuzo eziningi, okuhlanganisa ukukhululeka kwengcindezi, ikhwalithi yokushisela ethuthukisiwe, kanye nokusebenza kahle okwandisiwe. Inqubo ihilela ukukhetha okokusebenza okufanele, ukubeka indawo yokusebenza, ukusebenzisa ikhoyili yokungeniswa, kanye nokushisela. Ukushisa kwe-induction kuholela ekuhlanganyeleni okunamandla futhi okuhlala isikhathi eside futhi kunciphisa ingozi ye-porosity nokuqhekeka. Ngakho-ke, ukushiswa kwe-induction kunconywa kuzo zonke izinhlelo zokusebenza zokushisela.
