Uhlalutyo olunzulu loBuchule bokuJonga ubuGcisa boBuchwephesha obuDityanisiweyo kumatshini wokuwelda we-Inverter Spot ophakathi

Umgangatho wamalungu adityanisiweyo aveliswa ngoomatshini bokuwelda bendawo ephakathi-frequency inverter ibalulekile ekuqinisekiseni intembeko kunye nokusebenza kweemveliso ezahlukeneyo. Ukufezekisa ii-welds ezihambelanayo nezithembekileyo, kubalulekile ukuphumeza iindlela ezisebenzayo zokubeka iliso lomgangatho. Eli nqaku libonelela ngombono obanzi weendlela zokubeka iliso ezisetyenziselwa ukuvavanya umgangatho wamalungu adityanisiweyo kumatshini we-welding we-inverter spot we-medium-frequency.

1. Ukuhlolwa okubonakalayo: Ukuhlolwa okubonakalayo yindlela esisiseko yokuvavanya umgangatho wamalungu adityanisiweyo. Abaqhubi bahlola ngokubonakalayo indawo ye-weld ukuchonga iziphene eziqhelekileyo ezifana nokudityaniswa okungaphelelanga, i-spatter egqithisileyo, iintanda, okanye ukubunjwa kwe-nugget engafanelekanga. Ukuhlolwa okubonakalayo kunokwenziwa kusetyenziswa izixhobo zokukhulisa, ezifana ne-microscopes okanye iiborescopes, ukunyusa uviwo lwe-welds entsonkothileyo okanye ekunzima ukufikelela kuyo.
2. Iindlela zoVavanyo olungonakalisi (NDT): Iindlela zokuvavanya ezingonakalisi zidlala indima ebalulekileyo ekuvavanyeni ukunyaniseka kwangaphakathi kunye nomgangatho wamalungu adibeneyo ngaphandle kokwenza umonakalo. Ezinye iindlela eziqhele ukusetyenziswa ze-NDT zokujonga umgangatho koomatshini bokuwelda bendawo ye-inverter ephakathi ibandakanya:

• Uvavanyo lwe-Ultrasonic (UT): I-UT isebenzisa amaza omsindo we-high-frequency ukuze ibone iziphene zangaphakathi ezifana nokungabikho kwe-fusion, i-porosity, okanye i-cracks kwi-joint welded. Amaza abonakalisiweyo ayahlalutywa ukuze kubonwe ubungakanani, imilo, kunye nendawo yeziphene.
• Uvavanyo lweRadiographic (RT): I-RT ibandakanya ukusetyenziswa kwe-X-rays okanye imisebe ye-gamma ukwenza imifanekiso ye-welded joint. Ivumela ukufunyanwa kweziphene zangaphakathi, ezifana nokufakwa, i-voids, okanye ukungahambi kakuhle. Imifanekiso yeRadiographic inokubonelela ngolwazi oluneenkcukacha malunga nomgangatho we-weld kunye nokuthembeka.
• Uvavanyo lweMagnetic Particle (MT): I-MT isetyenziselwa ikakhulu imathiriyeli ye-ferromagnetic. Inkqubo ibandakanya ukusetyenziswa kwentsimi yamagnetic kunye nokusetyenziswa kwamasuntswana magnetic. Naziphi na iziphene eziqhekezayo, ezifana nokuqhekeka okanye i-laps, ziphazamisa i-magnetic field, ezibangela ukuba iinqununu ziqokelele kwiindawo eziphosakeleyo kwaye zibonakale.
• I-Dye Penetrant Testing (PT): I-PT ifanelekile ukufumanisa iziphene zomhlaba kwizinto ezingenayo i-porous. Inkqubo ibandakanya ukusebenzisa idayi enemibala kumphezulu, ukuvumela ukuba ingene kuzo naziphi na iziphene eziqhekeza phezulu. Idayi eyongezelelweyo iyasuswa, kwaye umphuhlisi usetyenziselwa ukunyusa ukubonakala kweziphene.

3. Uvavanyo loomatshini: Iindlela zokuvavanya oomatshini zisetyenziselwa ukuvavanya iipropathi zoomatshini kunye namandla adibeneyo adibeneyo. Ezinye iindlela eziqhelekileyo ziquka:

• Uvavanyo lwe-tensile: Uvavanyo lwe-tensile lubandakanya ukusebenzisa amandla e-tensile kwijoyinti elidityanisiweyo de laphuka. Olu vavanyo lunceda ekumiseleni ukomelela kokugqibela kwejoyinti, ukomelela kwesivuno, kunye nobude, inika ingqiqo kwimfezeko yomatshini.
• Uvavanyo lokuqina: Uvavanyo lokuqina lulinganisa ubulukhuni bejoyinti edityanisiweyo kusetyenziswa izixhobo ezikhethekileyo, ezifana nomvavanyi wobulukhuni. Inika isibonakaliso samandla edibeneyo kunye nokuchasana nokuguqulwa.

4. I-In-Process Monitoring: Iinkqubo zokubeka iliso kwiinkqubo zivumela ukuhlolwa kwexesha langempela kwiiparitha ze-welding kunye nezikhombisi zekhwalithi ngexesha lokusebenza kwe-welding. Obu buchule bubandakanya ukusetyenziswa kwezivamvo okanye iinkqubo zokubeka iliso ukubamba kunye nokuhlalutya idatha enxulumene nangoku, umbane, ubushushu, okanye amandla. Ukuphambuka kwimida emiselweyo okanye indlela echazwe kwangaphambili kunokubangela izilumkiso okanye uhlengahlengiso oluzenzekelayo ukugcina umgangatho we-weld ongaguqukiyo.

Ubuchule obusebenzayo bokubeka iliso obusemgangathweni buyimfuneko ekuqinisekiseni ukuthembeka kunye nokusebenza kwamalungu adityanisiweyo aveliswe ngoomatshini bokuwelda bendawo ye-inverter ye-medium-frequency. Ngokudibanisa uhlolo olubonakalayo, iindlela zovavanyo ezingonakalisi, uvavanyo koomatshini, kunye nokubekwa kweliso kwinkqubo, abavelisi banokuwuvavanya ngokupheleleyo umgangatho wee-welds. Obu buchule buvumela ukubonwa kwangaphambili kweziphene, ukuqinisekisa ukuba amanyathelo okulungisa anokuthathwa ngokukhawuleza ukuze kugcinwe umgangatho ophezulu we-welds kunye nokuhlangabezana nemigangatho efunekayo. Ukuphumeza iindlela ezomeleleyo zokubeka iliso ezisemgangathweni kuphucula ukusebenza kakuhle kunye nokusebenza koomatshini be-welding be-inverter spot welding, ekhokelayo.
