3. Txiav thiab sib sau
Thermal Cutting: Nplaim taws (Oxy- roj) lossis Plasma txiav yog tus qauv. Vim yog 5% Chromium cov ntsiab lus, cov npoo txiav yuav tawv heev. Nws raug nquahu kom zom cov tawv tawv "kub- cuam tshuam" ntug ua ntej vuam tom ntej.
Cold forming: Chav kawm 1 daim hlau muaj qhov zoo tshaj plaws formability. Txawm li cas los xij, yog tias cov kab mob ntau dua 5%, qhov kev ntxhov siab tom ntej - kev kho mob los yog kev kho cua sov tag nrho feem ntau yuav tsum tau ua los ntawm cov cai (xws li ASME BPVC).
Kub txoj kev: Ua ntawm 850℃thiab 1050 degree. Yog tias kub- tsim, lub phaj yuav tsum tau mus rau tag nrho Normalizing thiab Tempering lub voj voog rov qab los kho cov khoom siv kho tshuab.
4. Kev kho deg & tshuaj xyuas
Pickling lossis Blasting: Siv los tshem cov nplais ua ntej tsim kom ntseeg tau siab -welds zoo.
Nondestructive Testing (NDT): Standard txheej txheem rau 2026 tej yaam num koom nrog Ultrasonic Testing (UT) ib ASTM A435 thiab Sib Nqus Particle Inspection (MPI) ntawm weld seams los xyuas micro- tawg.
