Welding TechnologyWelding low-temperature steel requires the use of low-hydrogen welding materials, controlling the heat input during welding to prevent the weld seam from becoming brittle.

Heat TreatmentAfter welding, heat treatment may be required to relieve residual stress and enhance toughness.

Inspection and TestingIncluding non-destructive testing (such as RT, UT), pressure testing, and low-temperature impact testing, etc.
