Lesi sihloko sikhuluma ngombuzo wokuthi ingabe umshini wokushisela we-medium frequency inverter spot womshini wokushisela uyaphuma yini i-pulsed direct current (DC).Ukuqonda uhlobo lokuphuma kukagesi kubalulekile ekuhloleni ukufaneleka komshini wokushisela wezinhlelo ezithile zokusebenza kanye nokwenza kahle inqubo yokushisela.
- Umgomo Wokusebenza: Umshini wokushisela indawo ye-frequency inverter ophakathi usebenza ngomgomo wokuguqula okokufaka okushintshayo kwamanje (AC) kube okuphumayo kwamanje (DC) okuqondile ngokusebenzisa isekethe ye-inverter.Isifunda se-inverter sihlanganisa izingxenye ezifana nezihlungi nezihlungi ezilawula ukuphuma kwe-waveform.
- I-Pulsed Operation: Ezimweni eziningi, imishini yokushisela i-medium frequency inverter spot yenzelwe ukuletha i-pulsed current ngesikhathi senqubo yokushisela.I-pulsed current isho i-waveform lapho okwamanje kushintshana ngezikhathi ezithile phakathi kwamazinga aphezulu naphansi, okudala umthelela oshaya ngamandla.Lesi senzo sokushaya singanikeza izinzuzo ezihlukahlukene, okuhlanganisa okokufaka okuncishisiwe kokushisa, ukulawula okuthuthukisiwe kwenqubo yokushisela, kanye nokuhlanekezela okuncishisiwe.
- I-Direct Current (DC) Ingxenye: Nakuba umshini wokushisela indawo ye-medium frequency inverter uletha ngokuyinhloko i-pulsed current, uqukethe nengxenye yamanje eqondile (DC).Ingxenye ye-DC iqinisekisa i-arc yokushisela ezinzile futhi inomthelela ekusebenzeni kokushisela okuphelele.Ukuba khona kwengxenye ye-DC kusiza ukugcina ukuzinza kwe-arc, kuthuthukisa impilo ende ye-electrode, futhi kusize ukungena kwe-weld okungaguquki.
- Ukulawula Okuphumayo: Umshini wokushisela we-medium frequency inverter spot welding uvumela ukulungisa imvamisa ye-pulse, ubude be-pulse, kanye ne-amplitude yamanje, ihlinzeka ngokulawula inqubo yokushisela.Le mingcele eguquguqukayo inika amandla opharetha ukuthi basebenzise izimo zokushisela ngokususelwa kumpahla, ukumiswa okuhlanganyelwe, nezici zokushisela ezifiselekayo.
Umshini wokushisela indawo ye-frequency inverter emaphakathi ngokuvamile ukhipha i-pulsed current nengxenye yamanje eqondile (DC).I-pulsed current inikeza izinzuzo mayelana nokulawula okokufaka ukushisa kanye nekhwalithi ye-weld, kuyilapho ingxenye ye-DC iqinisekisa izici ezizinzile ze-arc.Ngokunikeza ukuguquguquka ekulungiseni imingcele ye-pulse, umshini wokushisela uvumela opharetha ukuba bafinyelele ukulawula okunembile phezu kwenqubo yokushisela.Ukuqonda izici zokuphuma komshini kubalulekile ekukhetheni imingcele yokushisela efanele kanye nokukhulisa ikhwalithi yokushisela nokusebenza kahle.
