Izinkinga Ezijwayelekile Okuhlangatshezwane Nazo Emishini Yokushisela I-Medium Frequency Inverter Spot

Imishini yokushisela i-Medium frequency inverter spot isetshenziswa kabanzi ezimbonini ezahlukahlukene ngokusebenza kahle kwayo kanye nempumelelo ekujoyineni izingxenye zensimbi. Kodwa-ke, njenganoma iyiphi enye inqubo yokushisela, ukushisela amabala kusetshenziswa le mishini kungahlangabezana nezinkinga ezithile ezithinta ikhwalithi nokuthembeka kokushisela. Lesi sihloko sihlose ukuxoxa ngezinkinga ezivamile ezingase ziphakame ngesikhathi sokushisela ngemishini ye-medium frequency inverter kanye nezixazululo ezingaba khona zokubhekana nazo.

1. Ukungena Kwe-Weld Okwanele: Enye yezinkinga ezivamile ekushiseleni kwendawo ukungena kwe-weld okwanele, lapho i-weld nugget yehluleka ukungena ngokugcwele emsebenzini. Lokhu kungabangelwa izici ezifana nokucindezela kwe-electrode okunganele, ukukhetha okungalungile kwempahla, noma imingcele ye-welding engalungile. Ukuze kuxazululwe le nkinga, kubalulekile ukuqinisekisa ukucindezela okufanele kwe-electrode, nokwandisa imingcele yokushisela (okwamanje, isikhathi, nobude besikhathi sokuminyanisa), bese ukhetha izinto ezifanele zama-electrode namasayizi ohlelo olunikeziwe.
2. I-Weld Spatter: I-weld spatter ibhekisela ekusakazeni okungathandeki kwensimbi encibilikisiwe phakathi nenqubo yokushisela. Kungabangela ukungcoliswa kwe-weld, ubuhle obumpofu, kanye nokulimala okungenzeka ezingxenyeni ezizungezile. I-weld spatter ivame ukubangelwa ama-welding currents aphezulu, i-electrode tip tip geometry engafanele, noma ukuhlanzeka okunganele kwendawo yokusebenza. Ukuze unciphise i-weld spatter, ukwenza ngcono imingcele yokushisela, ukugcina isimo esifanele sethiphu ye-electrode, kanye nokuqinisekisa ukulungiswa okwanele kwendawo (ukuhlanza nokwehlisa) isiqeshana somsebenzi kubalulekile.
3. I-Electrode Wear: Ukusetshenziswa okuphindaphindiwe kwama-electrode ekushiseleni indawo kungaholela ekugugekeni kwama-electrode, okuholela ekushintsheni kwejiyomethri ye-electrode kanye nokuncipha kokusebenza kokushisela. Ukugqoka kwe-electrode ngokweqile kungathinta ukuvumelana kanye nekhwalithi yama-welds. Ukuhlolwa njalo nokugcinwa kwama-electrode, njengokubunjwa kabusha noma ukushintsha ama-electrode agugile, kuyadingeka ukuze kuqinisekiswe ukusebenza kahle nokwelula ukuphila kwawo.
4. Ama-Weld Cracks: Ukuqhekeka kwe-Weld kungenzeka ngenxa yezinto ezifana nokushisa kwe-welding ngokweqile, ukulungiswa kwempahla enganele, noma ukulandelana kwe-welding engafanele. Le mifantu ingaphazamisa ubuqotho besakhiwo sejoyinti le-weld. Ukuze uvimbele ukuqhekeka kwe-weld, kubalulekile ukulawula okokufaka ukushisa kwe-welding, ukuqinisekisa ukuhlanzwa okufanele kwempahla kanye nokuhlanganisa ngokuhlanganyela, futhi ulandele ukulandelana kokushisela okufanele (okufana nezinhlangothi ezishintshayo) ukuze ukusabalalisa ukucindezeleka okushisayo ngokulinganayo.
5. Ikhwalithi yokushisela engahambisani: Ikhwalithi yokushisela engahambisani ingase ibalulwe ezicini ezihlukahlukene, okuhlanganisa ukuhluka kwezakhiwo zezinto ezibonakalayo, ukungahambi kahle kwe-electrode, noma ukulinganiselwa komshini okunganele. Ukuze uzuze ikhwalithi yokushisela engaguquki, kubalulekile ukusebenzisa izinto ezingaguquki nezisezingeni eliphezulu, ukuqondisa kahle ama-electrode, ukulinganisa umshini njalo, futhi uhlole ikhwalithi ngezikhathi ezithile usebenzisa izindlela zokuhlola ezingalimazi.

Isiphetho: I-Spot welding enemishini yokuguqula imvamisa emaphakathi ingahlangabezana nezinkinga ezimbalwa ezithinta ikhwalithi ye-weld kanye nokusebenza kwayo. Ukuqonda lezi zinkinga ezivamile nokusebenzisa izixazululo ezifanele kubalulekile ukuze kuzuzwe ukushiselwa kwamabala okuthembekile nokusezingeni eliphezulu. Ngokubhekana nezindaba ezinjengokungena okwanele, i-weld spatter, ukuguga kwe-electrode, ukuqhekeka kwe-weld, kanye nekhwalithi yokushisela engahambisani, opharetha bangakwazi ukuthuthukisa inqubo yokushisela indawo futhi baqinisekise imiphumela eyanelisayo kuzicelo zabo. Ukugcinwa njalo, ukubambelela emiqondisweni yokushisela, nokuqapha okuqhubekayo kwenqubo yokushisela kuyisihluthulelo sokunqoba lezi zinselele kanye nokuzuza ukushisela okuphumelelayo kwamabala.
