Ukusebenza kahle ku-Mid-Frequency Direct Current Spot Welding

I-Mid-frequency direct current spot welding iyinqubo yokushisela esebenza kahle kakhulu futhi eguquguqukayo enikeza inqwaba yezinzuzo ezinhlelweni ezihlukahlukene zezimboni. Kulesi sihloko, sizohlola izici ezingavamile kanye nezinzuzo zale ndlela yokushisela.

I-Mid-frequency direct current (MFDC) spot welding isithole ukuqashelwa kabanzi embonini yokukhiqiza ngokusebenza kwayo okuphakeme kokushisela kanye nezinzuzo eziningi. Le nqubo ibonakala ngokusetshenziswa kwayo kwe-direct current (DC) kumafrikhwensi ebanga eliphakathi, ngokuvamile phakathi kuka-1000 Hz no-100,000 Hz. Le ndlela enembile futhi elawulwayo ye-welding inikeza izici ezimbalwa eziphawulekayo.

1. Ukunemba nokulawula

Enye yamandla ayinhloko e-MFDC spot welding ukunemba nokulawula kwayo okungavamile. Ngokusebenzisa i-DC kumaza amaphakathi nebanga, abashiseli bangathola imiphumela enembe kakhulu futhi engaguquki. Lokhu kunemba kunenzuzo ikakhulukazi uma usebenza ngezinto ezincane noma izingxenye eziyinkimbinkimbi, njengoba kunciphisa ubungozi bokulimala futhi kuqinisekisa ukushisela kwekhwalithi ephezulu.

2. Indawo Eyehlisiwe Ethinteke Ukushisa (HAZ)

I-MFDC spot welding ikhiqiza ukushisa okuncane ngesikhathi senqubo yokushisela uma kuqhathaniswa nezindlela zokushisela zendabuko. Lokhu kubangela indawo encane ethinteke ukushisa (HAZ), ebalulekile ekugcineni ubuqotho bezinto eziyisisekelo. I-HAZ encishisiwe inciphisa ukuhlanekezela kanye nengozi yoshintsho lwensimbi, ikwenze kube ukukhetha okuhle kwezinhlelo zokusebenza lapho amandla nezinto ezibonakalayo kufanele zigcinwe.

3. Ukuphumelela Kwamandla

I-Mid-frequency welding iyonga amandla ngendlela emangalisayo. Ukusetshenziswa kwamandla e-AC anemvamisa ephezulu ezinhlelweni zokushisela ze-MFDC kuvumela ukulawula okunembile kokufaka kwamandla. Lokhu akugcini nje ukunciphisa ukusetshenziswa kwamandla kodwa futhi kunomthelela ekongeni izindleko ngokuhamba kwesikhathi.

4. I-Faster Welding Cycles

I-MFDC spot welding yaziwa ngemijikelezo yayo yokushisela esheshayo. Imvelo ye-high-frequency yamanje ivumela ukuncibilika ngokushesha kanye nokuqina kwe-weld pool, okuholela ezikhathini zokukhiqiza ezisheshayo. Lokhu kuyinzuzo ephawulekayo ezindaweni zokukhiqiza umthamo omkhulu.

5. Ukuzivumelanisa nezimo

Izinhlelo zokushisela ze-MFDC zivumelana nezimo kakhulu futhi zingenziwa ngezifiso ukuze zivumelane nezinhlelo zokushisela ezihlukahlukene. Ayakwazi ukushisela inhlobonhlobo yezinto zokwakha, okuhlanganisa inhlanganisela ehlukene yezinsimbi, futhi angamukela ukujiya kwempahla ehlukahlukene. Lokhu kuguquguquka kwenza i-MFDC yokushisela ifanelekele uxhaxha lwezimboni ezihlukahlukene, kusukela ekukhiqizeni izimoto kuya ekukhiqizeni ugesi.

6. Ikhwalithi nokuvumelana

Ukungaguquguquki kubalulekile ekukhiqizeni, futhi i-MFDC yokushisela iyahamba phambili kulokhu. Ukulawulwa okunembile kwemingcele yokushisela kuqinisekisa ukushisela okufanayo kuyo yonke inqubo yokukhiqiza, kunciphisa isidingo sokusebenza kabusha kanye nokuthuthukisa ikhwalithi yonke yomkhiqizo oqediwe.

I-Mid-frequency direct current spot welding iphuma phambili njengenketho enhle kakhulu ezinhlobonhlobo zezinhlelo zokushisela ngenxa yokunemba kwayo, ukulawula, ukusebenza kahle kwamandla, nokuvumelana nezimo. Ikhono layo lokukhiqiza amashisela ekhwalithi ephezulu anezindawo ezincane ezithinteke ekushiseni kuyenza ibe inketho ekhethwayo ezimbonini ezidinga kokubili ukusebenza nokungaguquguquki. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, ukushisela amabala kwe-MFDC cishe kuzohlala kuyinsika yokukhiqiza yesimanje, kube nesandla ekwenyukeni kokusebenza kahle nokonga izindleko.
