Does a tube box made of composite material Q345R+S30403, with partitions, require heat treatment? Help! !
If welding occurs during the processing of a tube box made of composite plate material Q345R+S30403, heat treatment is generally required to relieve welding stresses and improve the material’s properties. Especially for high-pressure vessels or applications with high requirements, heat treatment is essential. However, whether heat treatment is actually necessary depends on the design requirements and manufacturing specifications. It is recommended to consult relevant design and manufacturing experts for confirmation. .
Generally, heat treatment is required. If high corrosion resistance of the clad layer is required, intergranular corrosion testing after heat treatment is necessary, or a specialized welding process can be used without heat treatment.
