Litšitiso tse tloaelehileng tsa pipe weld
1. Porosity: Sekoli sena se etsahala ha lipokotho tsa moea li theha ka har'a weld, li fokolisa cheseletso. Porosity e ka bakoa ke tšilafalo, mongobo, kapa mekhoa e sa lokelang ea ho cheselletsa.
2. Undercut: Ha tšepe ea motsoali e pheletsong ea chesella e qhibiliha, ho thehoa groove, e fokolisang weld. Hangata sena se bakoa ke ho chesa haholo kapa lebelo le fosahetseng la welding.
3. Li-inclusions: Tsena ke lisebelisoa tse seng tsa tšepe tse ts'oarehang ka har'a weld le ho fokolisa chesele. Li-inclusions li ka tsoa ho slag kapa litšila tse ling tse neng li sa tlosoe hantle pele ho welding.
4. Ho petsoha: Mapetso a ka hlaha ka har'atube weldkapa sebaka se anngoeng ke mocheso ka lebaka la ho pholile ka potlako, thepa ea ho tlatsa e sa lokelang kapa khatello e feteletseng ea weld.
5. Insufficient Fusion: Bothata bona bo etsahala ha tšepe ea weld e sa kopane ka ho lekaneng le tšepe ea motsoali, e leng se etsang hore ho be le motsoako o fokolang. Sena se ka bakoa ke mocheso o sa lekaneng kapa mokhoa o sa lokelang oa ho cheselletsa.
Mokhoa oa ho thibela liphoso tsa ho cheselletsa
Ho thibela mefokolo ena e tloaelehileng ea ho cheselletsa liphaephe ho hloka motsoako oa koetliso e nepahetseng, tlhokomelo ea lisebelisoa, le ho khomarela mekhoa e metle. Maano a mang ao u ka a sebelisang ke ana:
1. Koetliso e Nepahetseng: Ho bohlokoa ho etsa bonnete ba hore li-welders tsa hau li koetlisoa hantle ka mekhoa ea li-arc welding. Koetliso ea kamehla e ka ba thusa hore ba lule ba tseba mekhoa le mekhoa ea morao-rao.
2. Taolo ea Boleng: Ho kenya ts'ebetsong mokhoa o matla oa ho laola boleng ho thusa ho lemoha mefokolo qalong ea ts'ebetso ea tlhahiso. Ho hlahlojoa le ho hlahlojoa khafetsa ha li-welds ho ka bona mathata pele a fetoha litaba tse tebileng.
3. Tlhokomelo ea Thepa: Tlhokomelo ea kamehla ea lisebelisoa tsa welding ke ea bohlokoa ho netefatsa ts'ebetso e nepahetseng. Sena se kenyelletsa ho hlahloba boemo bo nepahetseng, ho hloekisa le ho kenya likarolo tse tsofetseng.
4. Tokisetso ea Boitsebiso: Ho lokisetsa thepa ka nepo pele ho tjheseletsa ho ka fokotsa haholo kotsi ya bofokodi. Sena se kenyelletsa ho hloekisa bokaholimo ho tlosa litšila le ho netefatsa hore thepa e omme.

6. Sebelisa lisebelisoa tsa boleng: Ho reka lisebelisoa tsa boleng ba welding ho ka fokotsa monyetla oa ho ba le liphoso. Sena se akarelletsa ho sebelisa thepa e loketseng ea ho tlatsa le ho etsa bonnete ba hore boitsebiso ba botsoali bo finyella litlhoko tse nepahetseng.
Setsi sa rona se Cangzhou se hlahisa lithane tse 400,000 tsa lipeipi tsa tšepe tse spiral ka selemo ka basebetsi ba 680 ba inehetseng. Boitlamo ba rona ba boleng le boqapi bo re boloka re le ka pele indastering. Ka ho tsepamisa maikutlo ho thibeleng mefokolo e tloaelehileng ea liphaephe, re etsa bonnete ba hore liphaephe tsa rona tse cheselitsoeng ka spiral, haholo-holo tse sebelisoang liphaepheng tsa khase ea tlhaho, li finyella litekanyetso tse phahameng ka ho fetisisa tsa ho tšepahala le tsa tshebetso.
Ka kakaretso, ho utloisisa mefokolo e tloaelehileng ea liphaephe le ho kenya ts'ebetsong mehato ea thibelo ho bohlokoa ho baetsi ba indasteri ea lipeipi tse cheselitsoeng. Ka ho etelletsa pele boleng le koetliso, lik'hamphani li ka hlahisa lihlahisoa tse tšoarellang, tse tšepahalang tse emelang nako e telele.
