Yini Ebangela Imifantu Emikhiqizweni Eshiselwe Imishini Yokushisela I-Nut Spot?

I-Spot welding iyinqubo esetshenziswa kakhulu ekukhiqizeni, eyaziwa ngokusebenza kahle kwayo kanye nesivinini. Kodwa-ke, njenganoma iyiphi enye indlela yokushisela, akuvikelekile ezindabeni ezithile ezingathinta ikhwalithi yomkhiqizo wokugcina. Inkinga eyodwa evamile okuhlangatshezwana nayo lapho kusetshenziswa umshini wokushisela amantongomane ukuba khona kwemifantu emikhiqizweni eshiselwe. Kulesi sihloko, sizohlola izizathu ezingase zibangele lolu daba.

1. Ingcindezi Enganele:Isizathu esisodwa esiyinhloko sokuqhekeka emikhiqizweni eshiselwe ukucindezela okunganele okusetshenziswa ngesikhathi senqubo yokushisela. Uma ingcindezi inganele, insimbi encibilikisiwe ingase ingahlangani kahle, okuholela emalungeni abuthakathaka ajwayele ukuqhekeka.
2. Amapharamitha Welding Angalungile:Esinye isici esibalulekile ukusebenzisa imingcele yokushisela engalungile, njengamanje, isikhathi, noma amandla e-electrode. Le mingcele idinga ukulinganiswa ngokucophelela ngokusekelwe ezintweni ezishiselwe, futhi noma yikuphi ukuphambuka kusuka kuzilungiselelo ezifanele kungaholela ekuqhekekeni.
3. Ukungahambisani Kwezinto:Izinto ezishiselwayo kufanele zihambisane ukuze kuzuzwe ibhondi eqinile, engena-crack. Uma izinsimbi ezingafani noma izinto ezinobukhulu obuhlukahlukene zishiselwe, amathuba okuqhekeka ayanda, njengoba asabela ngendlela ehlukile kwinqubo yokushisela.
4. Ukungcoliswa kanye ne-Oxidation:Noma yikuphi ukungcoliswa endaweni okumele kushiselwe, njengokugqwala, uwoyela, noma okunye ukungcola, kungaphazamisa inqubo yokushisela futhi kudale izindawo ezibuthakathaka ezingase ziqhekeke. Ukwengeza, i-oxidation ingenzeka uma izindawo zensimbi zingahlanzwa kahle noma zivikelwe, okuholela ekushiselweni kwe-subpar.
5. Ukulungiswa Kwe-Electrode Okungalungile:Ama-Electrodes ayingxenye ebalulekile ekushiseleni kwendawo. Uma zigugile, zonakalisiwe, noma zigcinwe ngendlela engafanele, zingabangela ukungahambisani nenqubo yokushisela, okuholela ekuqhekekeni komkhiqizo wokugcina.
6. I-Thermal Stress:Ukushisisa okusheshayo nokupholisa ngesikhathi sokushisela kungadala ingcindezi yokushisa endaweni eshiselwe. Uma lokhu kucindezeleka kungaphathwa kahle, kungaholela ekwakhekeni kwemifantu ngokuhamba kwesikhathi.
7. Ukuntuleka Kokulungiselela Ngaphambi Kokushisela:Ukulungiselela kahle, okuhlanganisa nokuqondanisa izinto kanye nokuqinisekisa ukuthi zibambeke ngokuqinile, kubalulekile ukuvimbela imifantu ngesikhathi sokushisela. Ukulungiselela okunganele kungaholela ekungaqondiseni kahle noma ekuphikiseni, okubangela ukwakheka kwemifantu.

Sengiphetha, imifantu emikhiqizweni eshiselwe imishini yokushisela amantongomane ingaba nezimbangela ezihlukahlukene, ngokuvamile ezixhunyaniswa nezinkinga zokucindezela, imingcele yokushisela, ukuhambisana kwezinto ezibonakalayo, ukungcoliswa, ukugcinwa kwe-electrode, ukucindezeleka okushisayo, nokulungiswa kwangaphambili kwe-welding. Ukuze kukhiqizwe ama-welds asezingeni eliphezulu, angena-crack, kubalulekile ukunaka lezi zici futhi uqinisekise ukuthi inqubo yokushisela yenziwa ngokunemba nokunamathela emikhubeni engcono kakhulu. Ngokubhekana nalezi zinkinga, abakhiqizi bangathuthukisa ubuqotho nokuqina kwemikhiqizo yabo eshiselwe.
