Ngokukhula kwesidingo sekhwalithi ephezulu yokushisela, ukusebenza kahle kokukhiqiza, nokuzinza kwenqubo, abakhiqizi bayaqhubeka nokuthuthukisa imishini yabo yokushisela ukumelana. Imishini yokushisela indawo ye-AC yendabuko ingahlangabezana nezidingo eziningi zokushisela eziyisisekelo, kodwa ingase ibhekane nemikhawulo lapho abakhiqizi bedinga ukunemba okuphezulu, ukuphindaphinda okungcono, nokusebenza okuzinzile kwezinhlelo zokusebenza ezithuthukile.
AnI-MFDC inverter spot welding machineinikeza isixazululo esithuthuke kakhulu ngokusebenzisa ubuchwepheshe be-inverter ukuze kuzuzwe ukulawula okunembe kakhudlwana kwe-welding kanye nokuvumelana kwe-welding okuthuthukisiwe. Uma kuqhathaniswa nezinhlelo zokushisela ezivamile ze-AC, ubuchwepheshe bokushisela be-MFDC bunikeza ukulawula okungcono kokufaka ukushisa, ukusabela okusheshayo, nokuvumelana nezimo okuthuthukisiwe kwezingxenye ezinembayo.
Namuhla, imishini yokushisela indawo ye-MFDC isetshenziswa kabanzi ezimbonini ezinjengokukhiqiza izimoto, amabhethri emoto kagesi, amasistimu okugcina amandla, izingxenye zikagesi, kanye nemihlangano yensimbi enembile, lapho ukuthembeka kokushisela kuthinta ngokuqondile ukusebenza komkhiqizo wokugcina.
Nokho, ukukhetha imishini yokushisela efanele kudinga okungaphezu kokumane uqhathanise izilinganiso zamandla omshini. Abakhiqizi badinga ukucabangela izinhlobo zezinto ezibonakalayo, izimfuneko zokushisela, umthamo wokukhiqiza, izidingo zokuzenzakalela, kanye{1}}nezindleko zokusebenza zesikhathi eside.
Lesi sihloko sichaza ukuthi uyini umshini we-MFDC inverter spot welding, izinzuzo zawo ezibalulekile, izinhlelo zokusebenza, kanye nendlela yokukhetha isixazululo esifanelekile sokukhiqizwa kwezimboni.
I. I-MFDC Inverter Technology: I-Quality Leap ukusuka ku-AC kuya ku-DC
I-MFDC inverter spot welder isebenza ngokuqala ngokulungisa amandla ajwayelekile angu-50/60Hz AC ibe yi-DC, bese iwaguqulela ku-1-4kHz medium-imvamisa yamanje yamanje kusetshenziswa ubuchwepheshe be-inverter yemvamisa ephezulu. Lokhu kuphumelela kwezobuchwepheshe kunikeza izinzuzo ezibalulekile:
1. Okukhiphayo kwe-DC okuqhubekayo futhi okuzinzile, Ukuqeda "Zero-Ukuphazamiseka Okudlulayo"
Ama-spot welders endabuko e-AC ahlangabezana nokuphazamiseka kwamandla lapho i-waveform yamanje idlula iphoyinti elinguziro, okuholela ekufakweni kokushisa okungazinzile. Ubuchwepheshe be-MFDC bukhipha i-DC yamanje ebushelelezi, eqinisekisa:
- Okokufaka Ukushisa Okuqhubekayo Okuqinisekisiwe: I-current ayinazo iziro-iziphazamiso zokuwela, okuqinisekisa ukuthi amandla e-welding agxile ngokuqhubekayo futhi azinzile endaweni yokushisela, okunqoba ngempumelelo i-aluminium conductivity ephezulu ye-thermal.
- Ikhwalithi yokushisela ethuthukisiwe: I-waveform yamanje ezinzile inciphisa i-spatter kanye ne-porosity, okubalulekile ukuze kuzuzwe{0}}ikhwalithi ephezulu ye-weld nugget.
2. Ukuqeda Umphumela Wesikhumba Wokugxilisa Ukushisa Okuqondile
Ku-AC welding, i-current ivame ukugeleza ebusweni bomqhubi (owaziwa ngokuthi umphumela wesikhumba), ikakhulukazi kuma-currents aphezulu, okuholela ekusakazweni kokushisa okungalingani. I-MFDC isebenzisa-imvamisa yamanje emaphakathi, enciphisa kakhulu umphumela wesikhumba, okuvumela lokhu:
- Ukugxiliswa Kokushisa Okunembe Kakhudlwana: I-current ingena endaweni yokusebenza ngokufana kakhudlwana, igxilise ukushisa ngokuqondile kusixhumi esibonakalayo phakathi kwezinto ezimbili zokusebenza, kunasendaweni ye-electrode{0}}yomsebenzi.
- Ukuminyana Okuphezulu Kwamanje: I-MFDC ingafinyelela ukuminyana kwamanje kufika ku-150A/mm², iqinisekise ukujula okwanele kokungena ukuze yakhe indawo yokushisela eqinile.
