Ukulawula isikhathi sokulayisha kuqala kuyisici esibalulekile senqubo yokushisela emishinini yokushisela amantongomane. Lesi sihloko sichaza ukubaluleka kwesikhathi sokulayisha kuqala futhi sinikeza imininingwane yokuthi singaphathwa kanjani ngempumelelo ukuze kuzuzwe ukushisela okungaguquki nokuthembekile.
- Ukuqonda Isikhathi Sokulayisha Ngaphambili: Isikhathi sokulayisha kuqala sisho ubude besikhathi lapho ama-electrode acindezela khona inadi kanye nocezu lokusebenza ngaphambi kokuba kucushwe wamanje wokushisela. Le ngcindezi yokuqala, eyaziwa ngokuthi ukulayisha kuqala, iqinisekisa ukuthintana okufanele phakathi kwezingxenye futhi inciphise izikhala zomoya, okuholela ekuhlanganeni kwe-weld okuzinzile futhi okuvikelekile.
- Ukubaluleka Kwesikhathi Sokulayisha Ngaphambili: Ukulawula kahle isikhathi sokulayisha kuqala kubalulekile ukuze kuzuzwe ikhwalithi ephezulu yokushisela. Isikhathi esanele sokulayisha ngaphambili sivumela izindawo ezingaphezulu ukuthi zenze ukuxhumana okusondelene, kuncishiswe ubungozi bokushisela okungajwayelekile kanye nama-voids angaba khona. Ukwengeza, ikhuthaza ukuqhutshwa kokushisa okungcono, okuholela enkambisweni yokushisela efanayo futhi ephumelelayo.
- Izinto Ezithonya Isikhathi Sokulayisha Ngaphambili: Izinto ezimbalwa zithonya isikhathi esifanelekile sokulayisha kuqala emishinini yokushisela amantongomane, okuhlanganisa impahla yamantongomane, ukujiya kwezingcezu zokusebenza, i-welding current, namandla e-electrode. Ukuqonda lezi ziguquko nomthelela wazo ohlelweni lokushisela kubalulekile ekunqumeni isikhathi esifanele sokulayisha kuqala sezinhlelo zokusebenza ezithile.
- Ukuqapha Nokulungisa Isikhathi Sokulayisha Ngaphambili: Ukuze uzuze ukushisela okungaguquki, kubalulekile ukuqapha nokulawula isikhathi sokulayisha ngaphambilini ngokunembile. Imishini yokushisela amantongomane ethuthukisiwe ingase ifakwe izinzwa namasistimu azenzakalelayo ukuze ilinganise kahle futhi ilungise isikhathi sokulayisha kuqala ngokusekelwe kudatha yesikhathi sangempela phakathi nenqubo yokushisela.
- Ukulawula Isikhathi Sokulayisha Ngaphambi Kwesandla: Ezimweni lapho okuzenzakalelayo kungatholakali, opharetha bangakwazi ukulawula mathupha isikhathi sokulayisha kuqala. Lokhu kuhilela ukusebenzisa impendulo ebonakalayo nethintayo ukuze kuqinisekiswe ukuthi ama-electrode asebenzisa ingcindezi eyanele isikhathi esidingekayo ngaphambi kokuqala inqubo yokushisela.
- Ukulungiselela Isikhathi Sokulayisha Ngaphambili Ngezinhlelo Ezihlukene zokusebenza: Izinhlelo zokusebenza ezihlukene zokushisela amantongomane zingase zidinge ukuhluka kwesikhathi sokulayisha kuqala ukuze kufakwe izinto ezithile kanye nokucushwa okuhlanganyelwe. Ukwenza izivivinyo nezivivinyo kumasampula wokushisela kungasiza ekuboneni isikhathi esifanelekile sokulayisha kuqala sohlelo lokusebenza ngalunye oluhlukile.
- Ukugcina Ukungaguquguquki: Ukungaguquguquki kuyisihluthulelo sokuzuza ukushisela kwekhwalithi ephezulu. Ama-opharetha kufanele alwele ukugcina izikhathi zokulayisha kuqala ezingaguquguquki kukho konke ukusebenza kokushisela, ukugwema izinguquko ezingalindelekile ezingase zibe nomthelela ekuthembekeni kokushisela.
Ukulawula isikhathi sokulayisha kuqala emishinini yokushisela amantongomane kuyisici esibalulekile sokuqinisekisa ikhwalithi yokushisela namandla ahlangene. Ngokuqonda ukubaluleka kwesikhathi sokulayisha kuqala, kucatshangelwa izici ezinethonya, nokusebenzisa izinyathelo zokulawula ezinembile, abakhiqizi bangathuthukisa ukusebenza kahle nokuthembeka kwezinqubo zabo zokushisela. Isikhathi sokulayisha kusengaphambili esiphethwe kahle sinomthelela ekukhiqizeni amashisela aqinile futhi ahlala isikhathi eside, okwenza imishini yokushisela amantongomane ibe ithuluzi elibalulekile ezimbonini ezihlukahlukene.
