Ungawalungisa Kanjani Amapharamitha ku-I-MFDC Spot Welder?
Indawo ye-MFDC (Mid-Frequency Direct Current).ama-welders asetshenziswa kabanzi ezinhlelweni zokushisela insimbi. Ikhwalithi yabo yokushisela nokusebenza kahle kuncike kakhulu ekulungisweni okufanele kwamapharamitha. Ukwazi lezi zindlela zokulungisa kubalulekile ukuze uqinisekise ubuqotho be-weld nokusebenza kahle kokukhiqiza.
I. Amapharamitha angumongo weI-MFDC Spot Welders
Ngaphambi kokulungiswa, qonda le mingcele ebalulekile:
- Welding current
- Isikhathi sokushisela
- Amandla kagesi
- Isikhala se-electrode
Lezi kufanele zisethwe ngokusekelwe ezintweni ezibonakalayo kanye nezidingo zokushisela.
II. Okubalulekile{{1}Ukulungiswa Kwepharamitha Okususelwe
Izinto ezihlukile zidinga izilungiselelo ezenzelwe wena:
- Izinsimbi-ezincibilika{1}eziphezulu{1}}eziphezulu(isb, insimbi engagqwali):
Khulisa i-welding yamanje nesikhathi sokungena ngokugcwele.
- Izinto zokusebenza{0}ezingalungile(isb, ama-alloys e-aluminium):
Yehlisa isikhala samanje nesincane se-electrode ukuze uvimbele ukuhlangana okungaphelele.
III. Ukulungiswa-Kwesikhathi Sangempela Nge-Weld Inspection
Lungisa amapharamitha asuselwa kukhwalithi yokushisela:
- Isici: Ukufakwa kwe-Porosity/slag
Nciphisa samanje noma ukwandisa isikhathi weld.
- Ukuguqulwa kwamalunga okweqile
Nciphisa amandla e-electrode noma ulungiselele isikhathi sokubamba.
IV. Ukuqinisekisa Ukuzinza Kwepharamitha
Gcina ukungaguquguquki ngokusebenzisa:
- Ukulinganiswa kwemishini evamile
- Ukugcinwa kwe-electrode ehlanzekile/eyomile
- Amasistimu okuqapha{0}esikhathi sangempela(kunconyiwe)
V. Amasu Okulungisa
Sebenzisa izindlela ezifakazelwe:
- Ukushuna kwamanje: Yandisa/yehla kancane kancane ngenkathi uhlola ama-weld nuggets.
- Ukuhlaziywa kokusebenzelana kwepharamitha: Gwema izinguquko ezidlulele-zepharamitha eyodwa (isb, amandla aphezulu + amandla aphansi abangela i-splatter).
- I-DOE (Umklamo Wokuhlola): Hlola ngokuhlelekile izinhlanganisela zepharamitha.
