1. The kuwotcherera ndondomeko sikutanthauza kuwotcherera zipangizo (m'malo ndi chitoliro kukulitsa mbali).Chitoliro chachitsulo chimayikidwa muzitsulo za chitoliro choyenerera, ndipo mapeto a chitolirocho amawotchedwa mozungulira ndi tungsten argon arc welding (GTAW) kuti asungunuke chitoliro mu thupi limodzi.Msoko wowotcherera ndi payipi zimaphatikizidwa, mtundu ndi womwewo, ndipo zida zothandizira zowotcherera zimatha kuchotsedwa, ndipo liwiro la kuwotcherera limatha kuwongolera.

2. Pambuyo pakuyesa kukana kukakamiza, kutulutsa mpweya, kujambula, kukakamiza koyipa, ndi kupopera mchere, mphamvu yolumikizira ndi kusindikiza kwa zida zapaipi zimakhala ndi zabwino zoonekeratu kuposa njira zina zolumikizirana;ili ndi ntchito zambiri, ndipo "kugwirizanitsa kosagwirizana" Njira yolumikizira ili ndi ubwino wapadera makamaka m'zitsime zamapaipi, makoma ophatikizidwa ndi zochitika zina, ntchito zopulumutsa ndi zipangizo, kukonza bwino, ndi kukwaniritsa zofunikira zoteteza chilengedwe.

3. Kugwira ntchito kwamtengo wapatali, mawonekedwe osavuta opangira chitoliro, phindu lamtengo wapatali, lotetezeka ndi lodalirika, lokhazikika, lowoneka bwino, kuteteza chilengedwe, ndi ukhondo, zosavuta kugwiritsa ntchito ndi kusamalira.
