Kauv submerged arc welded steel yeeb nkab, tseem hu ua kauv welded yeeb nkab, kauv yeeb nkab, submerged arc welded steel yeeb nkab, thiab lwm yam., yog ib hom welded steel yeeb nkab uas lub vuam seam yog kauv-puab, ua los ntawm sawb hlau los yog coiled phaj. los ntawm ntau txoj kev ua haujlwm txias txias.
Vim li cas cov kauv submerged arc welded steel kav muaj qhov pores?
Cov pores nyob rau hauv loj-inch kauv welded kav tsis tsuas yog cuam tshuam qhov raug ntawm cov yeeb nkab weld thiab ua rau cov kav dej xau, tab sis kuj ua corrosion induction cov ntsiab lus, tiag txo lub zog thiab tsis kam ntawm cov weld. Feem ntau ntawm cov npuas nyob rau hauv kauv steel kav tshwm nyob rau hauv nruab nrab ntawm lub weld hlaws. Qhov laj thawj tseem ceeb yog tias hydrogen tseem muab zais hauv cov hlau welded hauv daim ntawv ntawm npuas. Nyob rau tib lub sijhawm, cov dej noo, av, oxide nplai thiab hlau filings nyob rau hauv lub flux, vuam Cheebtsam thiab npog txheej thickness, nto zoo ntawm steel phaj thiab kev kho mob ntawm steel phaj sab phaj, vuam txheej txheem thiab cov hlau. yeeb nkab txoj kev siv tshuab yuav tag nrho induce qhov tshwm sim ntawm pores nyob rau hauv lub kauv steel yeeb nkab.
Yog li ntawd, txhawm rau tshem tawm qhov tsis xws luag, nws yog ib qho tsim nyog yuav tsum tshem tawm cov xeb, roj, noo noo, thiab noo noo los ntawm vuam hlau thiab vuam seam, thiab ziab cov flux kom tshem tawm cov dej noo. Tsis tas li ntawd, ua kom cov tam sim no, txo qhov vuam ceev, thiab ua kom lub zog ceev ntawm cov hlau molten kuj tseem ua tau zoo.
