Indlela yokubona umgangatho weWeld Point kwiResistance Spot Welding Machines

I-Resistance spot welding yindlela esetyenziswa ngokubanzi kumashishini okuvelisa ukujoyina amacandelo esinyithi ngokufanelekileyo. Ukuqinisekisa umgangatho wamanqaku e-weld kubalulekile ukugcina imfezeko yesakhiwo kunye nokhuseleko lwemveliso yokugqibela. Kweli nqaku, siza kuxubusha indlela yokukhangela umgangatho we-weld kwindawo yokumelana nomatshini wokuwelda.

I-Resistance spot welding yinkqubo apho amaqhekeza amabini esinyithi adityaniswa ngokufaka ubushushu kunye noxinzelelo kwiindawo ezithile. Umgangatho wenqaku le-weld lixhomekeke kwizinto ezahlukeneyo, kubandakanywa iiparitha ze-welding, iipropati zezinto eziphathekayo, kunye nemeko ye-electrodes ye-welding. Ukukhangela kunye nokuqinisekisa umgangatho wala manqaku e-weld kubalulekile ukukhusela iziphene kunye nokugcina ukuthembeka kwamacandelo adibeneyo.

Indlela yokubona umgangatho weWeld Point

1. UHlolo Olubonwayo: Eyona ndlela ilula yokubona umgangatho we-weld point kungokuhlola okubonakalayo. Abaqhubi abanobuchule banokujonga iindawo ze-weld kwizitenxo ezinje ngokuqhekeka, i-voids, okanye ukungena okungonelanga. Ukuhlolwa okubonakalayo kunika ingxelo ngokukhawuleza kwaye kaninzi kuyindlela yokuqala yokukhusela ekulawuleni umgangatho.
2. Uvavanyo lwe-ultrasonic: Uvavanyo lwe-Ultrasonic yindlela engonakalisiyo esebenzisa amaza omsindo we-high-frequency ukuze ihlole isakhiwo sangaphakathi se-weld. Iyakwazi ukubona iziphene zangaphakathi ezinokuthi zingabonakali ngokuhlola okubonakalayo, njengokuqhekeka okufihliweyo okanye i-voids.
3. Ukuhlolwa kweX-reyi: Ukuhlolwa kwe-X-ray yenye indlela engonakalisi enika umfanekiso ocacileyo wesakhiwo sangaphakathi se-weld. Isebenza kakhulu ekufumaneni iziphene zangaphakathi kunye nokuqinisekisa ukuthembeka kwamanqaku e-weld ebalulekileyo.
4. Weld yangoku kunye Voltage esweni: Ukubeka iliso kwi-welding current kunye ne-voltage ngexesha lenkqubo ye-welding inokubonelela ngolwazi lwexesha langempela malunga nomgangatho we-weld. Ukuphambuka kwiiparameters ezichaziweyo kungabonisa imiba nge-weld, njengoqhagamshelwano olubi okanye ukungahambelani kwezinto.
5. Uvavanyo lwe-Shear kunye ne-Tensile: Ukuvavanya amandla omatshini we-weld, iisampulu zinokuthi zifakwe kwi-chear kunye novavanyo lwe-tensile. Olu vavanyo lumisela ukukwazi kwe-weld ukumelana namandla angaphandle kwaye iqinisekise ukuba iyahlangabezana neenkcukacha zamandla afunekayo.
6. Uhlalutyo lweMicrostructural: Uhlalutyo lwe-Microstructural lubandakanya ukuphonononga i-microstructure ye-weld phantsi kwe-microscope. Le ndlela inokutyhila ulwazi malunga nokwakheka kweenkozo ze-weld, ezinokuchaphazela iimpawu zayo zomatshini.
7. Idayi Penetrant Testing: Uvavanyo lokungena kwedayi yindlela esetyenziselwa ukufumanisa iziphene zomhlaba kwi-welds. Idayi yokungena ifakwe kwi-weld surface, kwaye nayiphi na idayi engaphezulu iyacinywa. Idayi iya kungena kwiziphene ezingaphezulu, izenze zibonakale phantsi kokukhanya kwe-UV.
8. Uvavanyo lweMagnetic Particle: Le ndlela ilungele ukufumanisa iziphene ezingaphezulu kunye nezikufuphi nomphezulu kwizinto ze-ferromagnetic. Amasuntswana amagnetic asetyenziswa kwi-weld, kwaye nakuphi na ukuphazamiseka kwintsimi yamagnetic okubangelwa ziziphene kuchongiwe.

Ukuqinisekisa umgangatho wamanqaku e-weld kumatshini wokuwelda indawo yokumelana kubalulekile ukugcina ingqibelelo yamacandelo adibeneyo. Ukusebenzisa indibaniselwano yokuhlola okubonakalayo kunye neendlela zokuvavanya ezingonakalisi ezifana novavanyo lwe-ultrasonic, ukuhlolwa kwe-X-ray, kunye nokuhlolwa kwe-weld yangoku kunokunceda ukufumanisa iziphene kunye nokuphambuka kwimigangatho yomgangatho. Uvavanyo lomatshini kunye nohlalutyo lwe-microstructural luqinisekisa ngakumbi ukuba i-welds ihlangabezana namandla afunekayo kunye neenkcukacha zesakhiwo. Ngokuphumeza ezi ndlela, abavelisi banokuvelisa iimveliso ezidityanisiweyo eziphezulu ngokuzithemba.
