Alloy cov ntsiab (CR, P, CU, thiab lwm yam): High P Des cov khaub thuas tawg; Cr / mo boosts hardenability, nquag martensite hauv haz.
Lub zog qib: high - lub zog qib (piv txwv li, Q690NH) nrog ntau dua tawg {{} ua rau muaj kev tawg.
Thickness / Mob: Daim Phiaj Cov Ntawv Tas Ra Phem Lis Ke Grainening; residual kev ntxhov siab lossis tuab teev ua kom muaj kev phom sij.
Mismatched muaj pes tsawg leeg (piv txwv li, cov electrodes zoo tib yam rau spa- h) tsim corrosion ib qho tsis muaj zog aav.
Lub zog tsis muaj zog (piv txwv li, qis - lub zog xaim x355Nh) ua rau muaj kev sib koom tes tsis txaus.
Cov tswv yim tshav kub: Tshaj tawm ua rau muaj kev nyuaj siab hnyav; tsis txaus ua tiav ua rau tsis tiav fusion.
Preheating / post {{- cua sov: tsis muaj preheating (piv txwv li,<100℃ for Q355NH below 0℃) induces cold cracking.
Vuam txoj kev: GMAW cov pa tiv thaiv kom zoo; Kaw cov khaub ncaws tuab tab sis tsis yog cov nyias nyias.
Kev tsim kho tsis zoo (cov grave me me lub ntsej muag) ua rau muaj kev puas tsuaj; Kev ntxhov siab ntawm kev ntxhov siab (Fillet Welds) accumulates residual kev ntxhov siab.
Rigid Constraints tiv thaiv kev cog lus, nce ntxiv kev ntxhov siab.
Siab - corrosion ib puag ncig (ntug dej hiav txwv / ntsev tshuaj tsuag) nrawm sib koom ua mob corrosion yog tias tsis meej.
Unremoved slag / spatter lossis tsis -} kho cov xeb txheej uas puas tsuaj tiv thaiv corrosion.
