Tsebo ea Mekhoa ea ho Welding ea Pipe: Tataiso e Pharalletseng
1. Utloisisa metheo ea mekhoa ea ho tjheseletsa pipe
Ho tjheseletsa lipeipi ho kenyelletsa ho kopanya likarolo tsa lipeipi ho etsa phala e sa khaotseng le e sa lutleng. Ts'ebetso ena e hloka kutloisiso e phethahetseng ea mekhoa ea ho cheselletsa e kang TIG (tungsten inert gas), MIG (metal inert gas) le stick stick. Theknoloji e 'ngoe le e' ngoe e na le melemo le mefokolo ea eona, 'me khetho ea theknoloji e itšetlehile ka lintlha tse kang mofuta oa thepa, bophara ba pipe le sebaka sa welding.

2. Tokiso ea ho tjheseletsa phala
Boitokisetso bo lekaneng bo bohlokoa pele o qala ts'ebetso ea welding. Sena se kenyelletsa ho hloekisa libaka tse lokelang ho chesetsoa, ho netefatsa hore liphaephe li kenngoa ka nepo le ho khetha lisebelisoa tse loketseng tsa ho tjheseletsa. Ntle le moo, ho bohlokoa ho latela melaoana ea polokeho le ho netefatsa hore sebaka sa mosebetsi ha se na likotsi tse ka bang teng.
3. Khetha thepa e nepahetseng
Khetho ea lisebelisoa tsa ho tjheseletsa e phetha karolo ea bohlokoa katlehong ea lenaneo la hau la ho tjheseletsa lipeipi. Sena se kenyelletsa ho khetha mochini o loketseng oa ho tjheseletsa, li-electrode tsa welding, likhase tse sireletsang le lisebelisoa tse ling. Ho bohlokoa ho tsetela lisebelisoa tsa boleng bo holimo ho netefatsa bots'epehi ba li-welds le sistimi eohle ea liphaephe.
4. Phethahatsa mekhoa e metle
Ho khomarela mekhoa e metle ho bohlokoa bakeng sa ho fumana tjheseletso ea lipeipi tsa boleng bo holimo le tse tšoarellang. Sena se kenyelletsa ho boloka liparamente tse nepahetseng tsa welding joalo ka voltage, hona joale le lebelo la maeto ho netefatsa ho kenella ka nepo le ho kopanngoa. Ho feta moo, ho itokisa hantle ka kopanelo, ho kenyelletsa ho itokisa le bevel, ho bohlokoa ho fihlela weld e matla le e tšepahalang.
5. Netefatsa Tumellano ea Khoutu
Liindastering tse ngata,mekhoa ea ho kenya lipeipie tlameha ho khomarela melao le litekanyetso tse khethehileng ho netefatsa botšepehi le polokeho ea tsamaiso ea liphaephe. Sena se ka kenyelletsa ho ikamahanya le lintlha tse kang ASME B31.3, API 1104, kapa AWS D1.1. Bahlahlobi ba li-welders le li-welding ba tlameha ho ba le kutloisiso e phethahetseng ea litlhaloso tsena le ho netefatsa hore mekhoa eohle ea li-welding e finyella litekanyetso tse hlokahalang.
6. Taolo ea boleng le tlhahlobo
Taolo ea boleng le tlhahlobo ke likarolo tsa bohlokoa tsa lenaneo la ho tjheseletsa lipeipi. Sena se kenyelletsa ho etsa tlhahlobo ea pono, tlhahlobo e sa senyeheng (NDT) le liteko tse senyang ho netefatsa boleng le bots'epehi ba li-welds. Bahlahlobi ba li-welding ba bapala karolo ea bohlokoa ho netefatsa hore lits'ebetso tsa welding li lumellana le litlhoko le litekanyetso tse boletsoeng.
Ka bokhutšoanyane, ho tseba mekhoa ea ho tjheseletsa lipeipi ho hloka motsoako oa botsebi ba tekheniki, lisebelisoa tse nepahetseng, ho latela mekhoa e metle, le ho latela maemo a indasteri. Ka ho latela litataiso tsena, li-welders li ka netefatsa ts'epo le ts'ireletseho ea lits'ebetso tsa liphaephe lits'ebetsong tse fapaneng tsa indasteri. Koetliso e tsoelang pele le tlhokomeliso ea tsoelo-pele ea morao-rao ea theknoloji ea ho tjheseletsa li bohlokoa hape bakeng sa ho tseba mekhoa ea ho tjheseletsa liphaephe le ho finyella bokhabane tšimong.
