Summary

 
The paper provides results of experimental studies regarding strength and fracture resistance of new weldable corrosion-resistant Al-Mg alloys 1550М and 1565ChМ and their welding joints at room temperature and at the cryogenic LNG temperature of –165 °С. The paper shows that the effect of cooling down to –165 °С practically does not affect tension diagrams of the samples under static load, and fracture resistance parameters grow as temperature decreases.
