Pipe ea tšepe e kentsoeng ka tlas'a metsi e fetohile phala ea tšepe ea merero e meholo ea lipalangoang tsa oli le khase lapeng le kantle ho naha ka lebaka la botenya ba eona bo boholo ba lerako, boleng bo botle ba thepa le theknoloji e tsitsitseng ea ts'ebetso. Likarolong tse kholo tse kentsoeng ka metsing a lipeipi tsa tšepe tsa arc, seam le sebaka se anngoeng ke mocheso ke libaka tse atisang ho ba le mefokolo e fapaneng, ha li-welding undercuts, li-pores, li-slag inclusions, fusion e sa lekaneng, ho kenella ho sa phetheheng, li-weld bumps, ho chesa. , le mapetsong a tjheseletsa Ke mofuta o ka sehloohong oa sekoli sa welding, 'me hangata ke tšimoloho ea likotsi tsa pipe ea tšepe ea arc e kentsoeng ka metsing. Mehato ea taolo ke e latelang:

1. Laola pele ho tjheseletsa:

1) Lisebelisoa tse tala li tlameha ho hlahlojoa pele, 'me feela ka mor'a ho feta tlhahlobo li ka kena sebakeng sa kaho ka mokhoa o hlophisitsoeng,' me li ikemiselitse ho sebelisa tšepe e sa tšoanelehang.
2) Ea bobeli ke tsamaiso ea lisebelisoa tsa welding. Hlahloba hore na lisebelisoa tsa ho tjheseletsa ke lihlahisoa tse tšoanelehang, hore na mokhoa oa ho boloka le oa ho baka o kenngoa ts'ebetsong, hore na bokaholimo ba lisebelisoa tsa welding tse ajoang bo hloekile ebile ha bo na mafome, ho sa tsotellehe hore na ho roala ha molamu oa welding ho tiile le hore na ho na le hlobo.
3) Ea boraro ke tsamaiso e hloekileng ea sebaka sa welding. Sheba bohloeki ba sebaka sa welding, 'me ha hoa lokela ho ba le litšila tse kang metsi, oli, mafome le filimi ea oxide, e phethang karolo ea bohlokoa ho thibela mefokolo e ka ntle ho weld.
4) Ho khetha mokhoa o loketseng oa tjheseletsa, molao-motheo oa ho tjheseletsa teko ea pele le ho tjheseletsa ho latelang o lokela ho kenngwa tshebetsong.

2. Taolo nakong ea welding:

1) Lekola hore na lintlha tsa terata ea welding le flux li nepahetse ho latela melaoana ea ts'ebetso ea welding ho thibela ts'ebeliso e fosahetseng ea mohala oa welding le flux le ho baka likotsi tsa welding.
2) Laola tikoloho ea ho cheselletsa. Ha tikoloho ea tjheseletsa e se ntle (mocheso o ka tlase ho 0℃, mongobo o lekanyeditsweng o feta 90%), mehato e tsamaellanang e lokela ho nkuwa pele ho tjheseletsa.
3) Pele ho tjheseletsa pele, hlahloba litekanyo tsa groove, ho akarelletsa le likheo, metshetshe lerootho, li-angles le misalignments, hore na ba kopana le ditlhoko tsa tshebetso.
4) Ho sa tsotellehe hore na motlakase oa ho tjheseletsa, lebelo la ho tjheseletsa, lebelo la ho tjheseletsa le mefuta e meng ya tshebetso e kgethilweng tshebetsong ya othomathike ya ho tjheseletsa arc e nepahetse.
5) Laola basebetsi ba tjheseletsa hore ba sebelise ka botlalo bolelele ba poleiti ea sefofane ea arc qetellong ea phala ea tšepe nakong ea welding ea arc e kenelletseng ka metsing, le ho matlafatsa ts'ebeliso e ntle ea sejana sa sefofane nakong ea welding ea kahare le kantle, e thusang ho ntlafatsa ho tjheseletsa ha pipe qetellong.
6) Laola hore na basebetsi ba tjheseletsa ba qala ho hloekisa slag nakong ea ho lokisa welding, hore na manonyeletso a se a sebelitsoe, ho sa tsotellehe hore na ho na le oli, mafome, slag, metsi, pente le litšila tse ling ho groove.
