AR400 STEEL Phajyog cov steel uas muaj kev cia siab thiab cov tawv nqaij kub thiab tej zaum yuav nyuaj rau Weld vim nws lub zog siab thiab ua tau nyuaj.
Thaum lub sij hawm vuam txheej txheem, lub hauv paus steel nyob ib ncig ntawm weld ntawm weld ntawm weld ntawm weld ntawm weld ntawm weld ntawm weld ntawm weld ntawm ar400 steel phaj yog rhuab thiab txias ib cheeb tsam cuam tshuam li cas (haz) nrog siab tawv.
Tej helrogen nyob rau hauv weld hlau ntawmAR400 STEEL PhajTej zaum yuav diffuse rau hauv haz thiab ua rau hydrogen embrittlement, uas ua rau qeeb tawg los yog ntiv taw tawg sab nraum lub weld.
Txhawm rau kom txo tau cov tawg hauv haz ntawm ar400 steel phaj kom ntau li ntau tau:
1. Siv - H4 lossis - H2 Cov Hydrogen ntau cov neeg muaj peev xwm
2. Lub AR400 steel phaj tau preheated kom qeeb qeeb tus nqi txias.
Nco ntsoov tias preheating ntau dhau yuav ua rau annealing ntawm ar400 steel phaj substrate
3. Cua txias qeeb. Lub sijhawm ntev dua ntawm qhov kub thiab txias, cov dej cawv uas yaj yuav dim;
4. Weld hlaws dai tau ntse los txo cov kev ntxhov siab weld residual;
5. Qhov tsawg kawg nkaus muaj lub zog muab lub rooj sib tham hlau lub rooj sib tham Cov qauv yuav tsum tau ua; Yog tias tus neeg faus Weld tau tsim, chav WELD yuav loj dhau los muab lub zog ntawm lub zog;
6. Txo cov ntaub pua chaw vuam ntawm ar400 steel phaj kom deb li deb tau;
