I-Medium-frequency direct current (MFDC) spot welding iyindlela yokushisela ebalulekile esetshenziswa ezimbonini ezahlukahlukene, njengezezimoto, i-aerospace, kanye neyokukhiqiza. Ukuqinisekisa ikhwalithi yokushisela kubaluleke kakhulu ukuze kuqinisekiswe ubuqotho besakhiwo kanye nokuphila isikhathi eside komkhiqizo wokugcina. Kulesi sihloko, sizoxoxa ngezici ezibalulekile zokuhlolwa kwekhwalithi ku-MFDC spot welding.
1. Ukuhlolwa kwe-Weld Seam:
Enye yezinto eziyinhloko zokuhlolwa kwekhwalithi ku-MFDC spot welding ukuhlolwa komthungo wokushisela. Lokhu kuhilela ukuhlola i-geometry, usayizi, kanye nokubukeka okuphelele kwe-weld. Umthungo oshiselwe kahle kufanele ube nesimo esifanayo, ungabi namaphutha abonakalayo njengokuqhekeka noma ukuqina, futhi ube nephrofayili yobuhlalu engaguquki. Noma yikuphi ukungahambi kahle ku-weld seam kungaholela ebuthakathakeni besakhiwo kanye nokuncipha kokusebenza komkhiqizo.
2. Ukuhlola Amandla Weld:
Ukuqinisekisa ubuqotho bemishini ye-weld, ukuhlola amandla kubalulekile. Izindlela ezahlukahlukene zingasetshenziswa, njengokuhlola okuqinile noma ukuhlola ukugoba, ukuze kuhlolwe ikhono le-weld lokumelana nengcindezi. Imiphumela yalezi zivivinyo kufanele ihlangabezane noma yeqe amazinga ashiwo, njengoba kunqunywa iphrojekthi noma izidingo zemboni.
3. Ukuhlaziywa kwamapharamitha kagesi:
I-MFDC spot welding incike ekulawuleni okunembile kwemingcele kagesi, okuhlanganisa yamanje, i-voltage, nesikhathi. Ukuqapha nokuhlaziya le mingcele kubalulekile ekulawuleni ikhwalithi. Ukuchezuka emananini ashiwo kungaholela kukhwalithi yokushisela engahambisani. Ngakho-ke, ukuqapha okuqhubekayo nokuhlaziya kubalulekile ukuze kuqinisekiswe ukuthi umshini wokushisela usebenza ngendlela efanele.
4. Electrode Wear and Maintenance:
Isimo sama-electrode wokushisela sibalulekile kwikhwalithi yokushisela kwamabala. Ukuhlolwa njalo kwama-electrode ukuze kuguge futhi kudabuke kuyadingeka. Ama-electrode agugile angaholela ekuxhumaneni okungalungile, okuholela ekushiseni okungahambisani. Ukugcinwa okufanele kanye nokushintshwa kwama-electrode uma kunesidingo kubalulekile ukuze kugcinwe izinga.
5. Indawo yokushisela kanye nokuphepha:
Ukuhlolwa kwekhwalithi kufanele futhi kucabangele indawo yokushisela kanye nezinqubo zokuphepha. Indawo yokusebenza ehlanzekile futhi enomoya omuhle ibalulekile ekuqinisekiseni ikhwalithi yamashisela. Ukwengeza, ukubambelela ezimisweni zokuphepha kubalulekile ukuze kuvikelwe abaqhubi kanye nokuqinisekisa ubuqotho benqubo yokushisela.
6. Amadokhumenti nokugcinwa kwamarekhodi:
Ukugcina amarekhodi aphelele enqubo yokushisela kubalulekile ekulawuleni ikhwalithi nokulandeleka. Lawa marekhodi kufanele afake imininingwane efana nemingcele yokushisela, ulwazi lomsebenzisi, imiphumela yokuhlolwa, nanoma yiziphi izinyathelo zokulungisa ezithathiwe.
Sengiphetha, ukuhlolwa kwekhwalithi ku-medium-frequency direct spot welding kuyinqubo enezici eziningi. Ukuqinisekisa ikhwalithi yokushisela kuhilela ukuhlolwa kwe-weld seams, ukuhlolwa kwamandla, ukuqapha imingcele kagesi, ukugcinwa kwe-electrode, ukugcina indawo ephephile yokushisela, kanye nemibhalo ngokucophelela. Lezi zinyathelo zihlangene zifaka isandla ekukhiqizweni kwekhwalithi ephezulu yokushisela ehlangabezana namazinga emboni kanye nokulindelwe ngamakhasimende.
