Ukuhlolwa komgangatho ngumba obalulekileyo we-medium-frequency inverter spot welding ukuqinisekisa ukuthembeka kunye nokuthembeka kwamalungu e-weld. Eli nqaku ligxile ekuxoxeni ngeendlela ezahlukeneyo kunye nobuchule obusetyenziselwa ukuhlolwa komgangatho kwiinkqubo ze-welding ye-inverter spot welding.
- Ukuhlolwa okubonakalayo: Ukuhlolwa okubonakalayo yeyona ndlela iphambili esetyenziselwa ukuvavanya umgangatho we-spot welds. Abaqhubi bajonga ngokubonakalayo amalunga e-weld kuzo naziphi na iziphene ezibonakalayo ezifana nokudityaniswa okungaphelelanga, ukuqhekeka, i-porosity, okanye imilo ye-nugget engaqhelekanga. Ukuhlolwa okubonakalayo kunceda ukuchonga ukungafezeki komphezulu kunye nokungahambelani okunokuthi kuchaphazele ukunyaniseka kwesakhiwo se-welds.
- Umlinganiselo woMda: Umlinganiselo wobukhulu ubandakanya ukuvavanya imilinganiselo ebonakalayo yeewelds ukuqinisekisa ukuba ziyahlangabezana neemfuno ezichaziweyo. Oku kubandakanya ukulinganisa iparameters ezifana nediameter ye-nugget, ukuphakama kwe-nugget, i-weld diameter, kunye nobukhulu bokungena. Imilinganiselo yobungakanani idla ngokusetyenziswa kusetyenziswa iikhalitha, iimicrometers, okanye ezinye izixhobo zomlinganiselo ochanekileyo.
- Uvavanyo olungabhubhiyo (NDT): Iindlela zokuvavanya ezingonakalisi zisetyenziselwa ukuvavanya umgangatho wangaphakathi we-spot welds ngaphandle kokwenza umonakalo. Iindlela eziqhelekileyo ze-NDT ezisetyenziswa kwi-medium-frequency inverter spot welding zibandakanya: a. Uvavanyo lwe-Ultrasonic (UT): Amaza e-Ultrasonic asetyenziselwa ukufumanisa iziphene zangaphakathi ezifana ne-voids, i-porosity, kunye nokungabikho kokudibanisa ngaphakathi kwee-weld joints. b. Uvavanyo lweRadiographic (RT): I-X-rays okanye imisebe ye-gamma isetyenziselwa ukuhlola i-welds kwiziphene zangaphakathi ezifana nokuqhekeka, ukudibanisa okungagqibekanga, okanye ukufakwa. c. Uvavanyo lweMagnetic Particle (MT): Iisuntswana zemagneti zisetyenziswa kwindawo ye-weld, kwaye ubukho bokuphazamiseka kwamagnetic bubonisa iziphene zomhlaba okanye ezikufutshane. d. Uvavanyo lwe-Dye Penetrant Testing (PT): Idayi enemibala isetyenziswe kwi-weld surface, kunye nedayi ewela kwiziphene eziqhekezayo zibonisa ubukho babo.
- Uvavanyo loomatshini: Uvavanyo lomatshini lwenziwa ukuvavanya amandla kunye neempawu zoomatshini ze-welds yendawo. Oku kubandakanya iimvavanyo ezitshabalalisayo ezifana novavanyo lwe-tensile, uvavanyo lokucheba, okanye uvavanyo lwe-peel, olubeka i-weld joints kwimikhosi elawulwayo ukumisela umthamo wabo wokuthwala umthwalo kunye nokuthembeka kwesakhiwo.
- Uhlalutyo lweMicrostructural: Uhlalutyo lwe-Microstructural lubandakanya ukuvavanya i-microstructure ye-weld zone usebenzisa ubuchule be-metallographic. Oku kunceda ukuvavanya iimpawu zentsimbi ye-weld, ezifana nokwakheka kweenkozo, indawo yokudibanisa, indawo echatshazelwe bubushushu, kunye nakuphi na ukungahambi kakuhle kwe-microstructural enokuthi ichaphazele iipropathi ze-weld's mechanical.
Ukuhlolwa komgangatho linyathelo elibalulekileyo ekuqinisekiseni ukuthembeka kunye nokusebenza kwee-welds ze-spot eziveliswe ngoomatshini bokuwelda be-inverter be-medium-frequency spot. Ngokusebenzisa uhlolo olubonakalayo, umlinganiso wobungakanani, uvavanyo olungonakalisi, uvavanyo koomatshini, kunye nohlalutyo lwe-microstructural, abavelisi banokuvavanya ingqibelelo ye-weld kwaye bachonge naziphi na iziphene okanye ukutenxa kwimigangatho efunekayo. Iindlela ezisebenzayo zokuhlola umgangatho zenza igalelo kwimveliso ye-welds ekumgangatho ophezulu ehlangabezana neemfuno ezingqongqo zamashishini ahlukeneyo.
