Tsim nyog vuam yog qhov tseem ceeb los tswj cov nqaj hlau nqaj:
Preheating:Yuav tsum muaj cov ntu tuab (S355) txhawm rau tiv thaiv kev tawg.
Xaiv electrode:Tsawg - hydrogen rods rau high- lub zog hlau.
Post - Weld Kev Kho Mob:Kev ntxhov siab - rov qab kom tsis txhob distortion.
Fabrication yuav tsum ua rawsEn 1090 cov qauvkom ntseeg tau kev nyab xeeb.
