1. Ububanzi bangaphandle-Ngokusekelwe kumlinganiselo ojikelezayo ±0.5% yobubanzi bangaphandle obuchaziweyo.
2. Umahluko ongaphandle kobubanzi phakathi kobubanzi obukhulu nobubanzi obuncinci bangaphandle.
3. Ulungelelwaniso-Ukusebenzisa umphetho othe tye ongama-3m ubude ukuze omabini amacala adibane nombhobho, 1/8 in. (3mm).
4. Ubukhulu-Ubude bodonga obuncinci nakweyiphi na indawo kumbhobho akufuneki bube ngaphezulu kwe-0.01 intshi (0.3mm) phantsi kobukhulu obumiselweyo.
5. Ubude obuneziphelo ezingafakwanga matshini buya kuba ngaphakathi kwe -0,+1/2 intshi (-0,+13mm) kwezo zichaziweyo. Ubude obuneziphelo ezifakwe ngomatshini buya kuba njengoko kuvunyelwene phakathi komenzi kunye nomthengi.
Uvavanyo loxinzelelo—Iimpawu zoxinzelelo ezinqamlezileyo zejoyinti edibeneyo ziya kuhlangabezana neemfuno ezisezantsi zokuqina koxinzelelo lwento ekhankanyiweyo yepleyiti.
Uvavanyo olugobileyo olukhokelwa yi-transverse-guided weld-belt —Uvavanyo lokugoba luya kwamkeleka ukuba akukho mifantu okanye ezinye iziphene ezidlula i-1/8 intshi (3mm) kulo naliphi na icala ezikhoyo kwisinyithi esigobileyo okanye phakathi kwesinyithi esigobileyo kunye nesinyithi esisisiseko emva kokugoba.
Uvavanyo lweRadiographic-Ubude obupheleleyo be-weld nganye yeklasi X1 kunye ne-X2 buya kuhlolwa ngeradiographic ngokuhambelana neemfuno ze-ASME Boiler kunye nePressure Vessel Code, iCandelo lesixhenxe, isiqendu UW-51.
