(1) Chepetsani malo owotchera momwe mungathere kuti mupewe ndi kuchepetsa ming'alu, potero kuwongolera moyo wa chida.
(2) Mphamvu yowotcherera imatsimikiziridwa pogwiritsa ntchito zida zowotcherera zolimba kwambiri komanso kugwiritsa ntchito njira zowotcherera zolondola.
(3) Onetsetsani kuti zowotcherera owonjezera satsatira mutu wa chida pambuyo brazing, kutsogoza m'mphepete akupera.Mfundozi zimasiyana ndi zomwe kale zinkagwiritsidwa ntchito popanga zida za multi-blade hard alloy, zomwe nthawi zambiri zinkakhala ndi mapangidwe otsekedwa kapena otsekedwa.Zotsirizirazi sizinangowonjezera kupsinjika kwa brazing ndi kuchitika kwa ming'alu, komanso zinapangitsa kuti kuchotsedwa kwa slag kukhala kovuta panthawi yowotcha, zomwe zimapangitsa kuti slag atsekeredwe kwambiri mu weld ndi kutsekeka kwakukulu.Komanso, chifukwa cha mapangidwe olakwika a groove, zowotcherera zochulukirapo sizikanatha kuwongolera ndikuwunjika pamutu wa zida, zomwe zidapangitsa kuti pakhale zovuta pogaya.Chifukwa chake, chidwi chapadera chiyenera kulipidwa popanga zida zamitundu yambiri zolimba.
Chowotchereracho chiyenera kukhala chonyowa bwino ndi alloy yolimba kukhala yolimba komanso gawo lapansi lachitsulo.
Iyenera kuwonetsetsa kuti weldyo ali ndi mphamvu zokwanira kutentha kwa chipinda komanso kutentha kokwera (monga zida zolimba za alloy ndi nkhungu zina zimakhala ndi kutentha kosiyanasiyana pakagwiritsidwa ntchito).
Kuonetsetsa zomwe zili pamwambazi, zowotcherera ziyenera kukhala ndi malo otsika osungunuka kuti achepetse kupsinjika kwa mawotchi, kuteteza ming'alu, kukulitsa luso la mawotchi, ndikuwongolera momwe amagwirira ntchito.
Zowotcherera ziyenera kuwonetsa kutentha kwambiri komanso kutentha kwachipinda kuti muchepetse nkhawa.Iyenera kukhala ndi kuyenda kwabwino komanso kupenya, pomwe chinthuchi chimakhala chofunikira kwambiri pakumangirira zida zodulira zamitundu yambiri komanso zolumikizira zazikulu zolimba.
Zinthu zowotcherera siziyenera kukhala ndi zinthu zomwe zimakhala ndi mfundo zochepa za evaporation, kuteteza kuphulika kwa zinthu izi panthawi yotentha yamoto komanso kukhudza mtundu wa weld.
Zowotcherera siziyenera kukhala ndi zitsulo zamtengo wapatali, zosowa, kapena zinthu zovulaza thanzi la munthu.
