(1) Chepetsani malo osungiramo zinthu momwe mungathere kuti mupewe ndikuchepetsa ming'alu, motero muwongolere moyo wa chipangizocho.
(2) Mphamvu yowotcherera imatsimikizika pogwiritsa ntchito zipangizo zowotcherera zolimba kwambiri komanso kugwiritsa ntchito njira zoyenera zowotcherera.
(3) Onetsetsani kuti zinthu zowotcherera zochulukirapo sizimamatira kumutu kwa chida mutagwiritsa ntchito brazing, zomwe zimathandiza kupukusa m'mphepete. Mfundozi zimasiyana ndi zomwe zinkagwiritsidwa ntchito kale pazida zowotcherera zolimba za multi-blade, zomwe nthawi zambiri zimakhala ndi mapangidwe otsekedwa kapena otsekedwa pang'ono. Chomalizachi sichinangowonjezera kupsinjika kwa brazing ndi ming'alu, komanso chinapangitsa kuti kuchotsa slag kukhale kovuta panthawi yowotcherera, zomwe zimapangitsa kuti slag igwire kwambiri mu weld komanso kusweka kwakukulu. Kuphatikiza apo, chifukwa cha kapangidwe kosayenera ka groove, zinthu zowotcherera zochulukirapo sizikanatha kulamulidwa ndikusonkhanitsidwa pamutu wa chida, zomwe zimayambitsa zovuta panthawi yopukusa m'mphepete. Chifukwa chake, chisamaliro chapadera chiyenera kuperekedwa popanga zida zowotcherera zolimba za multi-blade.
Zipangizo zowotcherera ziyenera kukhala zonyowa bwino, popeza zitsulo zolimba zimayikidwa mu brazing komanso chitsulo.
Iyenera kuonetsetsa kuti cholumikiziracho chili ndi mphamvu zokwanira pa kutentha kwa chipinda komanso kutentha kwakukulu (popeza zida zolimba za alloy ndi nkhungu zina zimakumana ndi kutentha kosiyanasiyana panthawi yogwiritsa ntchito).
Ngakhale kuti zikutsimikizira zomwe zili pamwambapa, zinthu zowotcherera ziyenera kukhala ndi malo otsika osungunula kuti zichepetse kupsinjika kwa brazing, kupewa ming'alu, kukulitsa magwiridwe antchito a brazing, ndikukonzanso magwiridwe antchito a ogwiritsa ntchito.
Zipangizo zowotcherera ziyenera kukhala ndi kutentha kwapamwamba komanso kutentha kwa chipinda kuti zichepetse kupsinjika kwa chitsulo chosungunula. Ziyenera kuyenda bwino komanso kulola kulowa mosavuta, ndipo izi ndizofunikira kwambiri pokonza zida zodulira zachitsulo chosungunula ndi malo akuluakulu olumikizirana achitsulo chosungunula.
Zipangizo zowotcherera siziyenera kukhala ndi zinthu zomwe zimakhala ndi malo ochepa otuluka mpweya, kuti ziletse kutuluka kwa zinthuzi panthawi yotenthetsera brazing ndikukhudza ubwino wa weld.
Zipangizo zolumikizira siziyenera kukhala ndi zitsulo zamtengo wapatali, zosowa, kapena zinthu zina zomwe zingawononge thanzi la anthu.
