Litšepe tse timang li cheseletsa li hlahisa mathata a itseng ka lebaka la ho thatafala ha tsona le tlhoko ea ho boloka thepa eo li e batlang ka mor'a ho cheselletsa. Boemong ba ho tjheseletsa letheba la maqhubu a mahareng, sengoloa sena se shebane le lintlha le litataiso tsa litšepe tse timang. Ho utloisisa le ho latela lintlha tsena ke tsa bohlokoa bakeng sa ho fihlela litšepe tse tšepahalang le tsa boleng bo holimo lits'ebetsong tse hlokang tšepe e timang.
Khetho ea Lintho:
Ho bohlokoa ho khetha tšepe e ka timang bakeng sa welding. Litšepe tse fapaneng tse timang li na le libopeho tse fapaneng le litšobotsi tsa ho thatafala. Ke habohlokoa ho nahana ka lintlha tse kang matla a lakatsehang, ho tiea, le litlhoko tsa phekolo ea mocheso ka mor'a weld ha u khetha tšepe e ka timang bakeng sa kopo e itseng.
Moralo o Kopanetsoeng:
Moralo o kopanetsoeng o phetha karolo ea bohlokoa ho tjheseletsa ka katleho ha litšepe tse timang. Ho bohlokoa ho khetha tlhophiso e kopaneng e netefatsang ho lekana hantle, phihlello e lekaneng ea ho beha li-electrode, le kabo e nepahetseng ea mocheso. Meralo e tloaelehileng e kopanetsoeng bakeng sa litšepe tse timang e kenyelletsa manonyeletso a liropeng, manonyeletso a butt le T-joints.
Preheating le Interpass Temperature Control:
Ho futhumatsa tšepe pele ho welding ho ka thusa ho fokotsa kotsi ea ho phatloha le ho fokotsa khatello ea maikutlo. Mocheso oa preheating o lokela ho khethoa ho latela sebopeho sa tšepe le botenya. Ho feta moo, ho laola mocheso pakeng tsa li-welding ho bohlokoa ho thibela ho bata ho feteletseng le ho netefatsa botšepehi bo nepahetseng.
Mekhahlelo ea Welding:
Ho fetola litekanyo tsa tjheseletsa ho bohlokoa bakeng sa ho tjheseletsa ka katleho ha litšepe tse timang. Mekhabiso e kang ea hona joale ea welding, nako, matla a electrode, le nako ea ho pholisa e lokela ho laoloa ka hloko ho finyella ho kenella ka tsela e nepahetseng, ho kopanya le ho senya mocheso. Mekhahlelo ea tjheseletsa e ka 'na ea fapana ho ea ka tšepe e itseng e timang e cheselitsoeng, kahoo ho bohlokoa ho buisana le litlhahiso tsa moetsi le ho tsamaisa li-welds tsa liteko ho ntlafatsa litekanyetso.
Kalafo ea Mocheso ka Mor'a Weld:
Litšepe tse timang hangata li hloka kalafo ea mocheso ka mor'a weld ho fihlela thepa e lakatsehang ea mochini. Sena se ka kenyelletsa lits'ebetso tse joalo ka ho halefisa kapa ho tima le ho futhumatsa. Mokhoa o khethehileng oa phekolo ea mocheso o lokela ho khethoa ho latela boemo ba tšepe le litlhoko tsa ho thatafala, matla le ho tiea.
Taolo ea Boleng le Teko:
Ho kenya ts'ebetsong mehato ea ho laola boleng le ho etsa liteko tse nepahetseng ke tsa bohlokoa bakeng sa ho netefatsa botšepehi ba litšepe tse timang. Mekhoa ea tlhahlobo e sa senyeheng joalo ka tlhahlobo ea pono, tlhahlobo ea ultrasonic kapa tlhahlobo ea radiographic e lokela ho sebelisoa ho bona bofokoli bofe kapa bofe bo ka bang teng.
Litšepe tse timang tse nang le mochini oa welding oa maqhubu a mahareng a frequency inverter li hloka ho latela lintlha le litataiso tse itseng. Ka ho khetha ka hloko tšepe e ka timang, ho qapa lenonyeletso, ho laola mocheso oa preheating le mocheso oa interpass, ho ntlafatsa mekhoa ea ho tjheseletsa, ho sebelisa phekolo ea mocheso oa post-weld, le ho etsa taolo e feletseng ea boleng le tlhahlobo, li-welders li ka finyella li-welds tse tšepahalang le tsa boleng bo phahameng lits'ebetsong tse hlokang ho tima. tshepe. Ho latela litataiso tsena ho tla etsa bonnete ba hore likarolo tse cheselitsoeng li boloka thepa ea tsona e lakatsehang ea mochini, ho kenya letsoho ts'ebetsong e akaretsang le ho ts'epahala ha lihlahisoa tse feliloeng.
