Inqubo eshisayo yomshini wokushisela indawo yokugcina amandla idlala indima ebalulekile ekuzuzeni ukushisela okuyimpumelelo. Lesi sihloko sinikeza ukubuka kabanzi kwenqubo yokushisa ehilelekile ekushiselweni kwendawo yokugcina amandla, ichaza izigaba ezibalulekile nezici ezifaka isandla ekukhiqizeni ukushisa, ukudluliswa, nokulawula ngesikhathi sokusebenza kwe-welding.
- Ukukhiqiza Ukushisa: Ukukhiqiza ukushisa emshinini wokushisela indawo yokugcina amandla kufezwa ngokuyinhloko ngokukhipha amandla kagesi agciniwe. Amandla agcinwe kuma-capacitors akhululwa ngokushesha ngendlela yamanje kagesi, egeleza ngezinto zokusebenza. Lokhu kwamanje kuhlangabezana nokumelana, okuholela ekushiseni kwe-joule, lapho amandla kagesi eguqulwa abe amandla okushisa endaweni yokushisela.
- Ukudlulisa Ukushisa: Uma ukushisa sekukhiqizwe kusixhumi esibonakalayo se-weld, kungena inqubo yokudlulisa ukushisa. Lokhu kuhilela ukunyakaza kwamandla okushisa ukusuka endaweni yokushisela kuya ezintweni ezizungezile kanye nemvelo. Ukudluliswa kokushisa kwenzeka ngezindlela ezihlukahlukene, okuhlanganisa ukuqhutshwa, ukuguquguquka, kanye nemisebe. Izinga lokudlulisa ukushisa lincike ezintweni ezifana nezakhiwo zezinto ezibonakalayo, ukumiswa kwamalungu, nezimo ezizungezile.
- Ukuncibilika kanye Nokuqinisa: Ngesikhathi senqubo yokushisela, ukushisa kwendawo kubangela ukuthi izinto zokusebenza zifinyelele endaweni yazo yokuncibilika. Izinga lokushisa eliphezulu esibonakalayo se-weld liphumela ekuncibilikeni nasekuhlanganisweni okulandelayo kwezinto. Njengoba ukushisa kuncipha, izinto ezincibilikisiwe ziyaqina, zenze isibopho esiqinile se-metallurgical. Ukulawula okokufaka ukushisa nezinga lokupholisa kubalulekile ukuze kuqinisekiswe ukuhlangana okufanele futhi kugwenywe amaphutha njengama-undercuts noma izindawo ezithinteke kakhulu ukushisa.
- Ukulawula Okushisayo: Ukuthola ikhwalithi ye-weld efanele kudinga ukulawula okushisayo okunembile ngesikhathi senqubo yokushisela. Imishini yokushisela indawo yokugcina amandla inikezela ngezindlela ezahlukahlukene zokulawula amapharamitha ashisayo. Ama-opharetha angalungisa i-welding current, ubude be-pulse, namanye amapharamitha ukuze alawule okokufaka ukushisa futhi alawule ukusatshalaliswa kwezinga lokushisa ngaphakathi kwendawo yokusebenza. Lokhu kulawula kuqinisekisa ukushisela okungaguquki nokuphindaphindwayo, kunciphisa ubungozi bokushisa ngokweqile noma ukuhlanganisa okunganele.
- Indawo Ethinteke Ukushisa: Eduze nendawo yokushisela, isifunda esaziwa ngele-heat-affected zone (HAZ) ihlangabezana nezinguquko zokushisa ngesikhathi sokushisela. I-HAZ ithola amazinga ahlukene okushisa, okungaholela ekuguqulweni kwesakhiwo esincane, njengokukhula okusanhlamvu noma izinguquko zesigaba. Ubukhulu nobukhulu be-HAZ buncike kumapharamitha wokushisela, izakhiwo zezinto ezibonakalayo, kanye nokucushwa okuhlangene. Ukulawulwa okufanele kwenqubo yokushisa kusiza ukunciphisa ububanzi kanye nemiphumela engaba yingozi ye-HAZ.
Inqubo eshisayo yomshini wokushisela indawo yokugcina amandla iyisici esibalulekile sokuthola ukushisela okuphumelelayo nokusezingeni eliphezulu. Ngokusebenzisa isizukulwane esilawulwayo, ukudluliswa, nokuphathwa kokushisisa, opharetha bangakha amashisela athembekile futhi aqinile anokuphazamiseka okuncane kanye namaphutha. Ukuqonda inqubo yokushisa nokusebenzisa amasu okulawula afanele kuvumela izimo zokushisela ezithuthukisiwe, kuqinisekiswe ikhwalithi ye-weld engaguquki kanye nokuhlangabezana nezidingo zezinhlelo zokusebenza ezihlukahlukene zezimboni.
