Welding Property:
S32750 stainless steel pipes can be welded by GTAW, GMAW, SMAW and SAW welding methods. The welding materials used are shown in Table 1.25.10.4L is used for GTAW welding, 25.10.4LR and 25.10.4.LB are used for manual welding, and 25.10.4.LB alkaline electrodes are usually used when the welds have high toughness requirements.Table 2 Welding materials that can be used for dissimilar steel welding. The recommended line energy: 0.2 ~ 1.5kJ/mm. In order to avoid rapid cooling, upper limit is generally used for thick plate welding, while lower limit is mostly used for thin plate welding.In GTAW welding, pure argon or Ar+2%N2 protection is used.
