AWS E8015-B3L Low-alloy steels Metal powder welding terata kgokelo ya tjheseletsa
Sesebelisoa&Tse tloahelehileng&Hloko:
AWS E8015-B3L mofuta oa eleketrode ea letsoho ea tšepe e sa keneleng mocheso e lekanang le mofuta oa GB/T 5118 o tloaelehileng oa elektrode E5515-2C1ML, tumellanong le ISO 3580-B ea mohlala E5515-2CIML, e loketse 550 ℃ tlas'a mocheso o phahameng le o phahameng. phaephe ea khatello, mechine ea lik'hemik'hale ea maiketsetso, lisebelisoa tsa peterole ea peterole, joalo ka 2.5Cr1Mo tube plate, A335-P22 tube, A387Gr.22 poleiti. Re laola ka tieo phepelo ea thepa e tala, ka tlhahiso e tsoetseng pele ea tlhahiso ea theknoloji ea tlhahiso, sehlopha se seng le se seng sa thepa se felile tlhahlobo ea sehlahisoa, ho bareki ba na le ts'ebeletso e phethahetseng ea kamora thekiso. Re ela hloko lintlha tsohle tsa ts'ebetso. Feela ho fana ka lihlahisoa tsa boleng bo holimo.

AWS E8015-B3L mofuta oa letsoho oa ho tjheseletsa electrode bakeng sa tšepe e sa keneleng mocheso ke elektrode e tlase ea sodium hydrogen mofuta oa letsoho, e ntseng e na le khanyetso e ntle ea creep tlasa 550 ℃ mocheso o phahameng le maemo a ts'ebetso ea khatello e phahameng, 'me eleketrode e na le arc e tsitsitseng, e sa phatloheng, e ntle. ho theha, ho bonolo ho de-slagging le ts'ebetso e ntle haholo ea X-Ray. Ha ho tjheseletsa, poleiti e teteaneng e lokela ho ba le li-welding tse ngata, mocheso pakeng tsa lihlopha ha o fokotsehe ho feta mocheso oa preheating, welding e lokela ho phethoa ka nako, ho molemo ho se sitise. Haeba ho hlokahala khefutso ea li-interlayer, ho lokela ho nkoa mehato e thibelang mocheso le ho khoasolla butle, 'me ho lokela ho nkoa mehato e tšoanang ea ho futhumatsa pele ho chesetsoa bocha. Nakong ea ts'ebetso ea welding, ho lokela ho lefshoa tlhokomelo ea ho tlatsa sekoti sa arc, ho sila lenonyeletso, le ho tlosa lekhalo la arc (hot crack). Ha metsi a le kholoanyane, sekoti sa arc se tebile. Ka hona, litekanyo tsa ho tjheseletsa le matla a nepahetseng a ho tjheseletsa li lokela ho khethoa ho latela litaelo tsa ts'ebetso ea welding.
