Izizathu ze-Electrode Sticking Phenomenon kwi-Medium-Frequency Inverter Spot Welding ye-Galvanized Steel Sheets?

Amaphepha ensimbi asetyenziswa ngokuqhelekileyo kumashishini ahlukeneyo ngenxa yokumelana nokugqwesa kwawo okugqwesileyo. Nangona kunjalo, xa udibanisa isinyithi esinezibilini usebenzisa umatshini we-inverter we-medium-frequency spot welding, into eyaziwa ngokuba yi-electrode sticking ingenzeka. Eli nqaku lijolise ekuphononongeni izizathu zokunamathela kwe-electrode kwi-medium-frequency inverter spot welding of sheets galvanized steel sheets kunye nokubonelela ngengqiqo malunga nendlela yokunciphisa lo mbandela.

1. I-Zinc Vapor kunye nokuNxinaniswa: Esinye sezizathu eziphambili zokunamathela kwe-electrode kwi-welding sheet sheets ensimbi kukukhululwa komphunga we-zinc ngexesha lenkqubo ye-welding. Amaqondo obushushu aphezulu avelisiweyo ngexesha le-welding angenza i-vaporize i-zinc coating, emva koko idibanise kwaye ibambelele kwi-electrode surfaces. Oku kungcoliseka kwe-zinc kwenza umaleko obangela ukuba i-electrode ibambelele kwi-workpiece, ekhokelela kubunzima bokwahlula i-electrode.
2. Ukubunjwa kweZinc Oxide: Xa umphunga we-zinc okhutshiweyo ngexesha le-welding isabela nge-oksijini ye-atmospheric, yenza i-zinc oxide. Ubukho be-zinc oxide kwiindawo ze-electrode kwandisa umba wokunamathela. I-zinc oxide ineempawu zokubambelela, ezincedisa ukubambelela phakathi kwe-electrode kunye neshiti lensimbi.
3. I-Electrode Material kunye ne-Coating: Ukukhethwa kwezinto ze-electrode kunye nokugquma kunokuchaphazela ukuvela kwe-electrode sticking. Izixhobo ezithile ze-electrode okanye iingubo zinokuba nobudlelwane obuphezulu be-zinc, okwandisa amathuba okuncamathela. Ngokomzekelo, ii-electrodes ezine-copper-based composition zivame ukunamathela ngenxa yobudlelwane obuphezulu be-zinc.
4. Ukupholisa okungonelanga kwe-Electrode: Ukupholisa okungonelanga kwe-electrode kunokufaka isandla kwi-electrode sticking. Imisebenzi ye-welding ivelisa ubushushu obukhulu, kwaye ngaphandle kweendlela zokupholisa ezifanelekileyo, ii-electrode zinokutshisa ngokugqithisileyo. Ukushisa okuphakamileyo kukhuthaza ukunamathela komphunga we-zinc kunye ne-zinc oxide kwiindawo ze-electrode, okubangelwa ukunamathela.

Amaqhinga okuNciphisa: Ukunciphisa okanye ukuthintela ukuncamathelwa kwe-electrode xa udityaniswa ngamashiti entsimbi enomatshini wokuwelda we-inverter ophakathi, iindlela ezininzi zinokusetyenziswa:

1. Ukugqoka i-Electrode: Ukugqoka rhoqo i-electrode kubalulekile ukususa i-zinc buildup kunye nokugcina indawo ecocekileyo ye-electrode. Ukugcinwa ngokufanelekileyo kwe-electrode kunceda ukukhusela ukuqokelela kwe-zinc vapor kunye ne-zinc oxide, ukunciphisa ukuvela kokunamathela.
2. I-Electrode Coating Selection: Ukukhetha iingubo ze-electrode ezinobudlelwane obuphantsi be-zinc kunokunceda ukunciphisa ukunamathela. Iingubo ezineepropati ezichasene ne-stick okanye iingubo ezenzelwe ngokukodwa i-welding steel galvanized zingaqwalaselwa.
3. Ukupholisa okwaneleyo: Ukuqinisekisa ukupholisa okwaneleyo kwee-electrode ngexesha le-welding kubalulekile. Iindlela zokupholisa ezifanelekileyo, ezifana nokupholisa amanzi, zinokutshabalalisa ubushushu ngokufanelekileyo kwaye zithintele ukunyuka kobushushu obugqithisileyo be-electrode, ukunciphisa ukubakho kokuncamathela.
4. Ukulungiswa kweeParameters ze-Welding: Ukulungiswa kakuhle kweeparamitha ze-welding, njengangoku, ixesha le-welding, kunye ne-electrode force, kunokunceda ukunciphisa ukunamathela. Ngokufumana iisetingi ezifanelekileyo zeparamitha, inkqubo ye-welding inokuphuculwa ukuze kuncitshiswe i-zinc vaporization kunye nokuncamathela.

Ukwenzeka kwe-electrode encamathela kwi-medium-frequency inverter spot welding of galvanized sheet sheets kubalelwa ikakhulu kukukhutshwa komphunga we-zinc, ukubunjwa kwe-zinc oxide, izinto ze-electrode kunye nezinto zokwaleka, kunye nokungonelanga kwe-electrode yokupholisa. Ngokuphumeza izicwangciso ezifana nokugqoka i-electrode rhoqo, ukukhetha iingubo ezifanelekileyo ze-electrode, ukuqinisekisa ukupholisa okwaneleyo, kunye nokuphucula imilinganiselo ye-welding, umba wokubambelela unokunciphisa. La manyathelo aya kuba negalelo ekusebenzeni kakuhle kwe-welding, ukuphuculwa kwemveliso, kunye nomgangatho ophezulu we-welds xa usebenza ngamashiti ensimbi.
