Izinketho zamapharamitha we-Medium Frequency Spot Welder?

Ama-welder amabala aphakathi nendawo asetshenziswa kakhulu ezimbonini ezahlukahlukene ngekhono lawo lokukhiqiza izinto zokushisela eziqinile nezinembayo ngesikhathi esifushane. Laba bashiseli banikeza uhla lwezinketho zepharamitha ezingalungiswa ukuze kuzuzwe imiphumela ye-welding efanele. Kulesi sihloko, sizohlola izinketho ezibalulekile zepharamitha ezitholakalayo kumashisela amabala aphakathi nendawo.

1. I-Welding Yamanje:Enye yemingcele ebaluleke kakhulu i-welding current, enquma inani lokushisa okukhiqizwa ngesikhathi senqubo yokushisela. Imisinga yokushisela ephakeme iphumela ekushiseleni okuqinile, kodwa amandla amanje ngokweqile angaholela ekushintshashintsheni kwezinto noma ngisho nokushiswa. Ukuthola ibhalansi efanele kubalulekile.
2. Isikhathi sokushisela:Isikhathi sokushisela isikhathi lapho i-welding current isetshenziswa khona ezintweni zokusebenza. Idlala indima ebalulekile ekulawuleni okokufaka ukushisa kanye nekhwalithi iyonke ye-weld. Isikhathi sokushisela sifushane kakhulu singaholela ekushiseleni okubuthakathaka, kuyilapho isikhathi eside singabangela ukushisa ngokweqile kanye nokulimala ezintweni.
3. I-Electrode Force:Amandla e-electrode ingcindezi esetshenziswa ezintweni zokusebenza ngesikhathi sokushisela. Amandla okwanele e-electrode aqinisekisa ukuthintana okuhle phakathi kwezinto zokusebenza futhi asiza ekuzuzeni ukushisela okungaguquki. Kodwa-ke, amandla amaningi angakhubaza izinto noma aholele ekugqokeni kwama-electrode.
4. I-Electrode Diameter kanye Nomumo:Ubukhulu nokuma kwama-electrode okushisela kungaba nomthelela ekusabalaliseni ukushisa nokucindezela ngesikhathi sokushisela. Ukukhetha ububanzi obufanele be-electrode kanye nesimo sohlelo oluthile kungaba nomthelela ekushiseleni okufanayo futhi kunciphise noma yimiphi imiphumela engadingeki.
5. I-Electrode Material:Ama-Electrodes ngokuvamile enziwa ngama-alloys ethusi ngenxa ye-conductivity yawo enhle kakhulu nokumelana nokushisa. Kungase kudingeke izinto ezihlukene zama-electrode ngokusekelwe ezintweni ezishiselwayo kanye nekhwalithi yokushisela oyifunayo.
6. Imodi yokushisela:Ama-Welder spots aphakathi nendawo ngokuvamile ahlinzeka ngezindlela zokushisela eziningi, ezifana ne-single-pulse, i-double-pulse, noma izindlela ze-multiple-pulse. Lezi zindlela zilawula ukulandelana nesikhathi se-welding current pulses, ezithinta ukungena kwe-weld kanye nokwakheka kwe-nugget.
7. Isikhathi Sokupholisa:Ngemuva kokuthi i-welding current ivaliwe, isikhathi sokupholisa sivame ukusetshenziswa ngaphambi kokuba ama-electrode aphakanyiswe. Lokhu kuvumela indawo eshiselwe ukuthi iphole futhi iqine, kube nomthelela emandleni e-weld jikelele.
8. I-polarity:Amanye ama-medium frequency spot welders avumela i-polarity ye-welding current ukuthi ilungiswe. I-polarity ingathinta isiqondiso sokugeleza kokushisa kanye nekhwalithi ye-weld iyonke.
9. Izigaba ze-Pre-Welding kanye ne-Post-Welding:Lezi yizikhathi ezengeziwe zamanje eziphansi ezisetshenziswa ngaphambi nangemva kokushaya kwe-welding main. Basiza ekwehliseni ukuhlanekezelwa kwezinto kanye nokugxilisa ingcindezi endaweni yokushisela.

Sengiphetha, ukusebenza kwe-medium frequency spot welder kuncike kakhulu ekulawuleni okunembile kwemingcele ehlukahlukene yokushisela. Abakhiqizi nabasebenzi badinga ukucabangela lezi zinketho ngokucophelela ukuze bathole ikhwalithi yokushisela efiselekayo, amandla, nokuvumelana kwezinhlelo zokusebenza ezithile. Ukukhethwa nokulungiswa okufanele kwepharamitha kungaholela ezinkambisweni zokukhiqiza eziphumelelayo kanye nemikhiqizo eshiselwe esezingeni eliphezulu.
