| 1. Dab tsi yog qhov tsis xws luag "steel-melting captivity thiab o" nyob rau hauv seamless kav? | Nws yog ib qho chaw sab hauv defect uas ua los ntawm cov kab ntev nrog cov npoo tortuous. Nws pib los ntawmdov tsis xws luag xws li central porosity thiab axial segregation nyob rau hauv nruam nruam billet-4. |
| 2. Dab tsi yog qhov kev sib tw tseem ceeb hauv kev tsim cov loj - txoj kab uas hla, tuab - cov kav hlau stainless welded los ntawm ib txwm siv JCOE? | Nws feem ntau ua rau muaj qhov tsis xws luagnon-cov phab ntsa tuab, tsis sib xws, thiab tsis txaus roundness, uas ua rau tsis tshua muaj yield tus nqi thiab nyuaj rau kev nruam zus tau tej cov specifications-2. |
| 3. Lub hom phiaj tseem ceeb yog dab tsi thaum tsim lub vuam rau cov kav dej? | Lub hom phiaj tseem ceeb yog los xyuas kom meejlongitudinal strain tsis concentrated nyob rau hauv lub weld, tab sis yog faib ntau tusyees. Kev ua tiav qhov no tsis tu ncua yog qhov nyuaj vim muaj kev hloov pauv hauv cov ntaub ntawv thiab cov txheej txheem-3. |
| 4. Dab tsi tsis yog -kev ntsuas kev puas tsuaj yog qhov yuav tsum tau ua rau DIN 17175 Qib III Cov kav dej zoo? | 100% ultrasonic kuaj rau longitudinal tsis xws luag-9. |
| 5. Dab tsi ua rau "weld lwj" hauv austenitic stainless hlau? | Nws yog tshwm sim los ntawmkev xav, qhov twg chromium carbides precipitate ntawm grain ciam teb nyob rau hauv lub HAZ thaum lub sij hawm welding, depleting chromium thiab ua rau thaj tsam cuam tshuam rau intergranular corrosion. |
