Izimbangela Zemifantu Emajoyini Welding Okumelana

I-Resistance welding iyindlela esetshenziswa kabanzi yokuhlanganisa izinsimbi ezimbonini ezihlukahlukene, kodwa akuvikelekile ekuveleni kwemifantu emajoyini ashiselwe. Le mifantu ingaphazamisa ubuqotho besakhiwo sezingxenye ezishiselwe, okuholela ekuhlulekeni okungenzeka. Ukuqonda izimbangela zokuqhekeka kwamajoyinti we-welding welding kubalulekile ekuvimbeleni ukwenzeka kwawo kanye nokuqinisekisa ikhwalithi yemikhiqizo eshiselwe.

1. I-High Residual Stress:Esinye sezizathu eziyinhloko zokuqhekeka kwamajoyinti we-welding welding ukucindezeleka okuphezulu kwensalela okukhiqizwa ngesikhathi senqubo yokushisela. Njengoba impahla eshiselwe iphola ngokushesha futhi iqina, iyafinyela, ibangele ukucindezeleka kwakheke. Uma lokhu kucindezeleka kudlula amandla ezinto ezibonakalayo, kungakheka imifantu.
2. Ukulungiswa Kwezinto Ezingenele:Ukulungiswa kwempahla engalungile, njengokuba khona kokungcola okungaphezulu noma ama-oxides, kungavimbela ukwakheka kwe-weld eqinile. Lokhu kungcola kungakha izindawo ezibuthakathaka ejoyintini, kwenze kube lula ukuqhekeka.
3. I-Electrode Force engalungile:Ukusetshenziswa okufanele kwamandla e-electrode kubalulekile ekushiseni ukumelana. Amandla amakhulu angaholela ekucindezelekeni ngokweqile nasekuxoshweni kwezinto ezibonakalayo, kuyilapho amandla anganele angase abangele ukuhlangana okungaphelele. Zombili lezi zimo zingafaka isandla ekwakhekeni kwemifantu.
4. Isikhathi sokushisela esinganele:Isikhathi somjikelezo wokushisela kufanele silawulwe ngokucophelela. Isikhathi sokushisela sifushane kakhulu singase singavumeli ukushisa okwanele ukukhiqizwa, okuholela ekuhlanganiseni okungaphelele kanye nokuqhekeka okungaba khona.
5. Ukuhlukahluka kumapharamitha we-Welding:Imingcele ye-welding engahambisani, njengamanje nesikhathi, ingaholela ekuhlukeni kwekhwalithi yama-welds. Lokhu kuhlukahluka kungabandakanya izindawo zejoyinti lapho izinga lokushisa lingekho phezulu ngokwanele ukuze kuhlanganiswe kahle, okwenza izifunda ezivame ukuqhekeka.
6. Ukungafani Kwezinto:Izinto zokushisela ezinezakhiwo ezishisayo ezihluke kakhulu zingabangela imifantu. Amazinga ahlukene okunwetshwa kwe-thermal kanye nokufinyela angabangela ingcindezi kusixhumi esibonakalayo esihlanganyelwe, okuthuthukisa ukwakheka kokuqhekeka.
7. Ukupholisa okunganele:Ukupholisa okusheshayo kwelunga elishiselwe kungabangela ukuba libe brittle futhi kube lula ukuqhekeka. Ukwelashwa okufanele kwangemuva kokushisela noma ukupholisa okulawulwayo kungasiza ekudambiseni le nkinga.
8. I-Electrode Wear:Ngokuhamba kwesikhathi, ama-electrode okushisela angaguga noma angahambi kahle, okuholela ekusabalaliseni kwamanje okungalingani kanye nekhwalithi yokushisela esengozini. Lokhu kungase kubangele amaphuzu abuthakathaka angase agcine eqhekekile.

Ukuze kuncishiswe ukuvela kokuqhekeka kwamajoyinti wokushisela, abakhiqizi kufanele basebenzise izinyathelo eziqinile zokulawula ikhwalithi, bagcine imishini yokushisela njalo, futhi baqinisekise ukuqeqeshwa okufanele kwabashiseli. Ukwengeza, ukuhlola okuphelele kwezingxenye ezishiselwe kungasiza ekutholeni nasekulungiseni ukuqhekeka kusenesikhathi, kuvimbele ukwehluleka okungenzeka komkhiqizo kanye nokuqinisekisa ubuqotho bemikhiqizo yokugcina.
