Ho sa tsotellehe hore na motsoako oa welding o hokae, ha e le hantle ke pokello ea phihlelo ea welding. Bakeng sa ba qalang, maemo a bonolo ke boikoetliso ba mantlha, ho qala ka ho potoloha ebe o fetela pele ho boikoetliso ba maemo a tsitsitseng.
Motsoalle oa tjheseletsa e tsitsitseng ka lipeipi tjheseletsa ke rotational welding. Welding e tsitsitseng e bolela hore lenonyeletso la welding le ke ke la sisinyeha ka mor'a hore phaepe e kopane. Nakong ea ts'ebetso ea ho tjheseletsa, boemo ba tjheseletsa bo fetoha (ho rapama, ho theosa, ho ya hodimo le tlase).
Ho potoloha boema-kepe ba tjheseletsa ho bolela ho potoloha boemakepe ba tjheseletsa nakong ya tjheseletsa e le hore setjheseletsa se kgone ho etsa welding sebakeng se loketseng (se seng se tshekaletseng, se otlolohileng, ho ya hodimo kapa tlase).
Ha e le hantle, ho bua ka mokhoa o bonolo, li-welding tse tsitsitseng ke li-welds tse cheselitsoeng sebakeng sa marang-rang, tse bapisoang le liphaephe tse entsoeng esale pele.
Motsoako o tsitsitseng oa tjheseletsa o bolela hore phala ha e sisinyehe mme welder o etsa welding ka hohle. Haholo-holo ha ho cheseletsa holimo, mokhoa oa ho cheselletsa ho thata ho sebetsa, o hloka litlhoko tse phahameng tsa tekheniki bakeng sa welder, 'me o na le bofokoli. Hangata e hahiloe holim'a setsi sa lipeipi;
Boema-kepe ba rotary bo lumella phala ho potoloha, 'me boemo ba ho tjheseletsa ha e le hantle ke tjheseletsa e bataletseng kapa welding e otlolohileng. Ts'ebetso ea welding e bonolo ebile e na le liphoso tse fokolang. Ha e le hantle e hahiloe fatše kapa fatše.
Nakong ea tlhahlobo ea li-welding, e le ho thibela likou tsohle tse potolohang ho khethoa bakeng sa ho hlahlojoa le ho finyella tekanyo e phahameng ea ho feta, ho hlokahala ho hlahloba ka mokhoa o sa reroang karolo e itseng ea likou tse tsitsitseng ho netefatsa boleng ba ho tjheseletsa ba phaephe eohle. "Pressure Pipeline Safety Technical Supervision Regulations-Industrial Pipelines" e bolela hore karo-karolelano ea ho lemoha ha li-welding tse tsitsitseng ha li ka tlase ho 40%.
Tlas'a maemo a tloaelehileng, re sebelisa boema-kepe bo tsitsitseng e le boema-kepe bo tsamaisoang. Boema-kepe bo suthang ke lenonyeletso le cheselitsoeng esale pele la phaephe. Karolo ea liphaephe e ka sisinyeha kapa ea potoloha ha phaepe e se e entsoe ka ntle ho sebaka. Boema-kepe bo tsitsitseng ke boema-kepe bo kentsoeng tšimong, 'me phala ha e khone ho sisinyeha kapa ho potoloha ka nako ena.
Litlhaloso tsa liphaephe tsa liphaephe tsa libaka tse telele li bitsoa "libaka tse shoeleng" 'me li hloka "100% tlhahlobo ea radiographic." The dead joint welding angle e rarahane, 'me boleng ba tjheseletsa ha bo bonolo ho netefatsa.
Thepa ea welding ea Xinfa e na le litšobotsi tsa boleng bo holimo le theko e tlase. Ho fumana lintlha, ka kopo etela:Baetsi ba Welding & Cutting Manufacturers - China Welding & Cutting Factory & Suppliers (xinfatools.com)
Boema-kepe bo tsitsitseng ba tjheseletsa bo amana le boema-kepe ba tjheseletsa bo potolohang.
The rotating tjheseletsa kopanelo bolela hore nakong ea lipeipi prefabrication tjheseletsa tshebetso, lenonyeletso tjheseletsa ka rotated ka ho rata ho ea ka ho fetisisa phutholohile angle bakeng sa tshebetso tjheseletsa. Boleng ba welding bo batla bo tsitsitse, kahoo li-welders li rata mofuta ona oa motsoako oa ho cheselletsa.
Leha ho le joalo, ba bang ba workpiece tjheseletsa manonyeletso ka feela e tsitsitseng ka lebaka la maemo a sebaka kapa mefokolo ea workpiece ka boeona. Sena ke se bitsoang "fixed welding joint". Ha lenonyeletso le tsitsitseng la welding le kentsoe le ho chesetsoa, ho na le lenonyeletso le le leng feela la welding. Mofuta ona oa motsoako oa ho tjheseletsa o thata ho o tjheseletsa mme o hloka tekanyo e phahameng ya tlhahlobo e sa senyeheng.
Litaelong tse ling tsa kaho ea liphaephe, karolo ea tlhahlobo e tsitsitseng ea weld e boletsoe ka ho hlaka. Hobane li-angles tsa li-welding tse tsitsitseng li fapane, li-welding manual li tla fetoha, 'me boleng ba li-welding joints bo tla ba le tšusumetso e itseng. Ka mohlala, manonyeletso a tsitsitseng a liphaephe tsa tšepe a hloka hore li-welders li etse li-welding tsohle, tse behang litlhoko tse phahameng ho li-welders. Ehlile, ba na le mekhoa e phahameng le maemo a tekheniki. Motho ea chesehelang hantle ha a tsotelle.
Tsamaisong ea kaho, palo ea menyetla e tsitsitseng e lokela ho fokotsoa ka hohle kamoo ho ka khonehang. Ka lehlakoreng le leng, e ka laola boleng ba tjheseletsa, 'me ka nako e ts'oanang, e ka boela ea fokotsa palo ea maqeba a ho lemoha le ho fokotsa litšenyehelo.
