Isingeniso Semishini Yokushisela, I-Pre-Pressure, kanye nokubamba Isikhathi Emishinini Yokushisela Ephakathi Nemvamisa Ye-Inverter Spot

Imishini yokushisela indawo ye-medium-frequency inverter isetshenziswa kabanzi ezimbonini ezahlukahlukene ngekhono layo lokukhiqiza ama-welds aqinile futhi athembekile. Ukuqinisekisa ikhwalithi ephezulu yokushisela nokusebenza, kubalulekile ukuqonda imiqondo yokushisela, ingcindezi yangaphambili, nokubamba isikhathi kule mishini. Lesi sihloko sinikeza ukubuka konke kwe-welding, pre-pressure, kanye nokubamba isikhathi emshinini wokushisela we-medium-frequency inverter spot.

1. Ukushisela: Ukushisela kuyinqubo yokuqala lapho izingcezu zensimbi ezimbili noma ngaphezulu zihlanganiswa ndawonye kusetshenziswa ukushisa nokucindezela. Emishinini yokushisela indawo ye-inverter ye-medium-frequency, inqubo yokushisela ihlanganisa ukudlulisa amandla aphezulu kuma-workpieces ukukhiqiza ukushisa endaweni yokuxhumana. Ukushisa kubangela ukuba insimbi incibilike futhi yakhe i-weld nugget, eqina lapho ipholisa. I-weld nugget inikeza amandla nobuqotho belunga.
2. I-Pre-Pressure: I-Pre-pressure, eyaziwa nangokuthi i-squeeze noma i-electrode force, ibhekisela ekucindezelweni kokuqala okufakwe ezintweni zokusebenza ngaphambi kokuba kusebenze i-welding current. Ingcindezi yangaphambi kwesikhathi ibalulekile ukuze kuqinisekiswe ukuthintana okufanele kanye nokuhambisana phakathi kwezinto zokusebenza nama-electrode. Kuyasiza ukuqeda noma yiziphi izikhala noma ukungahambi kahle okungathinta ikhwalithi ye-weld. Amandla angaphambi kokucindezela kufanele abe anele ukusungula othintana naye ozinzile ngaphandle kokudala ukuwohloka ngokweqile noma ukulimala kweziqephu zokusebenza.
3. Isikhathi Sokubamba: Isikhathi sokubamba, esaziwa nangokuthi isikhathi sokushisela noma isikhathi se-nugget, ubude besikhathi lapho i-welding current igcinwa khona ngemva kwesigaba sangaphambili sokucindezela. Isikhathi sokubamba sivumela ukushisa ukuthi kusabalale ngokulinganayo futhi kusiza ukwakheka kwe-weld nugget ethuthuke kahle futhi eqinile. Ubude besikhathi sokubamba buncike ezintweni ezifana nempahla yokusebenza, ukujiya, amandla okushisela, kanye nekhwalithi yokushisela oyifunayo. Kubalulekile ukunquma isikhathi esikahle sokubamba ukuze kuzuzwe ukushisela okungaguquki nokuthembekile.

I-Welding, pre-pressure, kanye nesikhathi sokubamba yizici ezibalulekile ekusebenzeni kwemishini yokushisela indawo ye-medium-frequency inverter spot. Ukuqonda izimiso ezingemuva kwalezi zinqubo kubalulekile ukuze kuzuzwe ukushiselwa kwekhwalithi ephezulu ngamandla afanele nobuqotho. Ngokulungiselela amapharamitha wokushisela, okuhlanganisa amandla angaphambi kokucindezela nokubamba isikhathi, opharetha bangaqinisekisa ukushisela okuthembekile nokungaguquguquki ezinhlelweni ezihlukahlukene.
