Ukuhlolwa koMgangatho kwi-Medium-Frequency Inverter Spot Welding

Ukuhlolwa komgangatho ngumba obalulekileyo we-medium-frequency inverter spot welding ukuqinisekisa ukuthembeka kunye nokuthembeka kwamalungu e-weld.Eli nqaku lijolise ekuxoxeni ngeendlela ezahlukeneyo kunye nobuchule obusetyenziselwa ukuhlolwa komgangatho kwiinkqubo ze-welding ye-inverter spot welding.

1. 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.
2. Umlinganiselo woMda: Umlinganiselo wobukhulu ubandakanya ukuvavanya imilinganiselo ebonakalayo yeewelds ukuqinisekisa ukuba ziyahlangabezana neemfuno ezichaziweyo.Oku kubandakanya imilinganiselo yokulinganisa imilinganiselo efana nedayamitha yenugget, ubude benugget, idiameter yeweld, kunye nobukhulu bokungena.Imilinganiselo yobukhulu idla ngokusetyenziswa kusetyenziswa iikhalitha, iimicrometers, okanye ezinye izixhobo zomlinganiselo ochanekileyo.
3. 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 okungaphelelanga, 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.
4. 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.
5. 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.
