Ukunikezwa kokushisa okuqhubekayo okukhiqizwa yi-flat output current yomshini wokushisela imvamisa ephakathi kwenza izinga lokushisa le-nugget likhuphuke ngokuqhubekayo. Ngesikhathi esifanayo, ukulawulwa okunembile kwe-slope yamanje ekhuphukayo kanye nesikhathi ngeke kubangele i-spatter ngenxa yokushisa kokushisa kanye nesikhathi sokukhuphuka kwamanje esingalawuleki. Khiqiza.
I-intermediate frequency inverter spot welder inomshini wokushisela ophumayo oyisicaba, oqinisekisa ukusebenza kahle okuphezulu nokunikezwa okuqhubekayo kokushisa kokushisela. Futhi isikhathi sokusebenza kwamandla sifushane, sifinyelela izinga le-ms, okwenza indawo ye-welding ethinteke ukushisa ibe yincane, futhi amalunga e-solder akhiwe kahle.
Ngenxa yefrikhwensi ephezulu yokusebenza (imvamisa engu-1-4KHz) yomshini wokushisela we-intermediate frequency spot welding, ukunemba kokulawula impendulo izikhathi ezingama-20-80 zomshini wokushisela indawo we-AC ojwayelekile kanye nomshini wokushisela wendawo yokulungisa, kanye nokulawula okukhiphayo okuhambisanayo. ukunemba nakho kuphezulu kakhulu.
ukonga amandla 30%. Ngenxa yokusebenza kahle kokushisa okuphezulu, i-welding transformer encane kanye nokulahlekelwa okuncane kwensimbi, i-inverter welder ingonga amandla angaphezu kuka-30% kunomshini wokushisela indawo ye-AC kanye nomshini wokushisela wendawo wokulungisa lapho ushisela ucezu lokusebenza olufanayo.
Isetshenziselwa ukushisela amabala kanye nokushisela amantongomane ensimbi enamandla amakhulu kanye nensimbi eyakhiwe eshisayo embonini yokukhiqiza izimoto, ukushisela indawo kanye ne-multi-point projection welding yepuleti lensimbi elinekhabhoni eliphansi, ipuleti lensimbi engagqwali, ipuleti elinothayela, i-resistance brazing kanye indawo yokushisela kocingo lwethusi embonini kagesi enamandla naphansi, ukushisela indawo yesiliva, njll.
A: Lapho ugcina umshini wokushisela indawo, udinga ukunaka ukuphepha kukagesi kwemishini, ulondoloze ama-electrode futhi ugcine ezinye izingxenye zemishini.
A: Uma usebenzisa imishini yokushisela indawo, kufanele kuqashelwe ukuphepha kukagesi, ukuphepha komqhubi kanye nokusebenza okuvamile kwemishini.
IMPENDULO: Lapho ulungisa indawo yokushisela, udinga ukunaka ukuphepha kukagesi kwempahla, ubunzima bezobuchwepheshe bokulungisa, kanye nokusetshenziswa kwamathuluzi afanelekile.
A: Isizathu sokuhluleka komshini wokushisela indawo kungase kube izici ezihlukahlukene ezifana nokulimala kwezingxenye zikagesi, ukugqoka ama-electrode, nokuhluleka kwamandla.
A: Izindlela zokushisela zomshini wokushisela amabala zifaka i-manual spot welding, i-automatic spot welding kanye ne-semi-automatic spot welding.
A: Inqubo yokushisela yomshini wokushisela indawo izokhiqiza iphunga elikhethekile, futhi kuyadingeka ukugcina indawo enomoya omuhle.
