As the title suggests, what issues need to be considered during welding?
Additionally, I know that the main materials used for both cryogenic liquid nitrogen washing systems and the distillation towers in air separation plants are aluminum products, with LF2 being the primary material. From the material used in the liquid nitrogen scrubber equipment, I can see that it is mainly an aluminum-magnesium alloy. Can it be considered that the main component of LF2 is an aluminum-magnesium alloy?
Reply 2# sun0225: LF2 is a 5xxx series aluminum-magnesium alloy with a magnesium content of 2.0–2.8%. Under the new standards, LF2 has been replaced by 5A02
