I-Mid-frequency spot welding iyindlela esetshenziswa kakhulu ezimbonini ezahlukahlukene, njengezezimoto nezokukhiqiza, yokuhlanganisa izingxenye zensimbi. Ukuqinisekisa ikhwalithi yalawa majoyini wokushisela kubalulekile ukugcina ubuqotho nokuphepha komkhiqizo. Lesi sihloko sizodingida ekuhlaziyweni kwezindaba zekhwalithi ezijwayelekile ezihambisana namajoyinti wokushisela amabala aphakathi nemvamisa.
Udaba Lwekhwalithi 1: I-Weld Porosity I-Weld porosity ibhekisela ekubeni khona kwe-void encane noma imigodi endaweni ehlangene eshiselwe, engenza buthaka isakhiwo futhi yehlise ubuqotho buphelele be-weld. Izinto ezimbalwa zingaba nomthelela ekuqineni kokushisela, okuhlanganisa igesi enganele yokuvikela, imingcele yokushisela engafanele, noma izinsimbi eziyisisekelo ezingcolile. Izinyathelo ezisebenzayo zokulawula ikhwalithi, njengokuqapha igesi nokugcinwa njalo kwemishini yokushisela, kubalulekile ukubhekana nalolu daba.
Udaba Lwekhwalithi 2: Ukuqhekeka kwe-Weld Ukuqhekeka, noma ukwakheka kwemifantu endaweni ehlangene eshiselwe, kungenye ukukhathazeka kwekhwalithi okwandile. Kungenzeka ngenxa yokupholisa okusheshayo kwe-weld, ukushisa okunganele, noma amazinga aphezulu okucindezeleka okusala. Izinyathelo zokuvimbela ezifana nokulawula amazinga okupholisa, ukusebenzisa izinqubo ezifanele zokushisisa kwangaphambili, nokusebenzisa izinto zokugcwalisa ezifanele kungasiza ukunciphisa ukuqhekeka kwe-weld.
Udaba Lwekhwalithi yesi-3: Ukungena Okungaphelele Ukungena okungaphelele kwenzeka lapho i-weld yehluleka ukufinyelela ugqinsi olugcwele lwesisekelo, okuholela ekuhlanganeni okubuthakathaka. Izici ezinomthelela kule nkinga zihlanganisa i-welding current engalungile, usayizi we-electrode ongafanele, noma ukulungiswa kwamalunga okungavamile. Abaqhubi kufanele bathole ukuqeqeshwa okwanele futhi bahlole njalo okokusebenza kwabo kokushisela ukuze baqinisekise ukungena okufanele kanye nekhwalithi ehlangene engaguquki.
Udaba Lwekhwalithi yesi-4: I-Weld Spatter Weld spatter ukukhishwa kwezinhlayiya zensimbi ezincibilikisiwe ngesikhathi senqubo yokushisela, okungaholela ezingozini zokuphepha kanye nokunciphisa ubuhle. Ukugqoka ama-electrode okulungile, ukugcina izindawo zokusebenza zihlanzekile, nokulungisa amapharamitha wokushisela kunganciphisa ukuvela kwe-weld spatter.
Udaba Lwekhwalithi yesi-5: Ukugqokwa kwe-Electrode Isimo sama-electrode wokushisela sidlala indima ebalulekile ekuzuzeni ukushisela kwekhwalithi ephezulu. Ukuguga kwe-Electrode, okubangelwa izici ezifana nokupholisa okwedlulele kwamanje noma okunganele, kungaholela kwikhwalithi ehlangene engahambisani kanye nezindleko zokulungisa ezikhuphukayo. Ukusebenzisa ukuqapha kwama-electrode namashejuli okushintsha kungasiza ekuxazululeni le nkinga.
Isiphetho: Ukuqinisekisa ikhwalithi yamajoyinti okushisela amabala aphakathi nefrequency kubalulekile ukuze kugcinwe ubuqotho nokuphepha komkhiqizo ezimbonini ezihlukahlukene. Ngokubhekana nezindaba ezijwayelekile zekhwalithi ezifana ne-weld porosity, ukuqhekeka, ukungena okungaphelele, i-weld spatter, nokugqoka kwe-electrode, abakhiqizi bangathuthukisa izinqubo zabo zokushisela futhi bakhiqize amalunga athembekile, aphezulu we-weld. Izinyathelo zokulawula ikhwalithi ezisebenzayo, ukuqeqeshwa komsebenzisi, nokugcinwa njalo kwemishini yizici ezibalulekile ekuzuzeni ukushisela okungaguquki, kwekhwalithi ephezulu.
