Zingaphi Iindidi zeMacroscopic Fractures ezikhoyo kwiResistance Spot Welding?

I-Resistance spot welding yinkqubo eqhelekileyo kunye neyimfuneko kumashishini ahlukeneyo, kodwa ngaba ukhe wazibuza malunga neentlobo ezahlukeneyo zokuqhekeka kwe-macroscopic ezinokuthi zenzeke kule ndlela ye-welding? Kweli nqaku, siza kuphonononga iintlobo ezahlukeneyo zokuqhekeka kwe-macroscopic ezinokubonwa kwindawo yokumelana ne-welding.

1. Ukuqhekeka koMphakathi: Ukuqhekeka kobuso, okwakwaziwa ngokuba “kukwahlulwa kobuso bobuso,” kwenzeka kumdibaniso wezinto ezimbini ezidityanisiweyo. Olu hlobo lokuqhekeka luhlala ludibaniswa kumgangatho ophantsi we-weld kwaye lunokubangelwa yimiba efana noxinzelelo olunganeleyo okanye iiparitha ze-welding ezingafanelekanga.
2. Ukutsalwa kweqhosha: Ukuqhawula iqhosha lokukhupha iqhosha libandakanya ukukhutshwa kweqhosha lentsimbi etyhidiweyo eyenziwe ngexesha lenkqubo ye-welding. Oku kunokwenzeka xa izinto ze-weld zingabotshwanga ngokufanelekileyo kwizinto ezisisiseko, ezikhokelela ekubeni iqhosha likhutshwe ngexesha lokuvavanya.
3. Iinyembezi: Ukuqhekeka kweenyembezi kubonakaliswa ngokukrazulwa kwezinto ezisisiseko ezijikeleze indawo ye-weld. Olu hlobo lokuphuka ngokuqhelekileyo lwenzeka xa kukho igalelo lobushushu obugqithisileyo okanye xa iiparamitha ze-welding zingalawulwa kakuhle.
4. Iplagi: Ukuqhekeka kweeplagi kwenzeka xa inxalenye yesinye sezinto ezidibeneyo zihlulwe ngokupheleleyo kuyo yonke i-weld. Olu hlobo lokuphuka lunokubangelwa yimiba eyahlukeneyo, kubandakanywa ukungcoliswa kwi-electrodes ye-welding okanye ubuchule obungafanelekanga bokudibanisa.
5. I-Edge Crack: Iintanda zomphetho ziintanda ezakha kufutshane nomphetho wendawo edityanisiweyo. Zinokuvela kwizinto ezahlukeneyo ezifana nokulungiswa kwezinto ezimbi okanye ukulungelelaniswa kwe-electrode engafanelekanga.
6. I-Nugget Fracture: I-Nugget fractures ibandakanya ukungaphumeleli kwendawo ye-weld ephakathi, eyaziwa ngokuba yi "nugget." Ezi fractures zibalulekile kuba zinokubeka esichengeni ukuthembeka kwayo yonke i-weld. I-Nugget fractures ingabangela ukunyanzeliswa kwe-welding engafanelekanga okanye i-parameters ye-welding engafanelekanga.
7. Ukuqhekeka: Iifractures ze-Fissure zihlala ziqhekeza ezincinci okanye iifassure ngaphakathi kwempahla ye-weld. Oku kunokuba ngumceli mngeni ukubona ngokubonakalayo kodwa kunokuwenza buthathaka ulwakhiwo lwe-weld ngokubanzi. Iifissures zingenzeka ngenxa yemicimbi kunye nenkqubo ye-welding okanye umgangatho wezinto ezisetyenzisiweyo.

Ukuqonda ezi ntlobo zahlukeneyo zokuqhekeka kwe-macroscopic kwindawo yokumelana ne-welding kubalulekile ekuqinisekiseni umgangatho kunye nokuthembeka kwamalungu adityanisiweyo kwizicelo ezahlukeneyo. Abaqhubi be-welding kunye nabahloli kufuneka baqaphele ekufumaneni nasekujongeni ezi ziqhekeza ukugcina ukunyaniseka kwesakhiwo samacandelo adibeneyo.

Ukuqukumbela, i-resistance spot welding ingakhokelela kwiindidi ezahlukeneyo zokwaphuka kwe-macroscopic, nganye ineseti yayo yezizathu kunye neziphumo. Ukuchonga ezi fractures kunye nokujongana noonobangela bazo kubalulekile ekuveliseni iiwelds ezikumgangatho ophezulu ezihlangabezana nemigangatho engqongqo yamashishini anamhlanje.
