Annealing treatment
Thread Content
After the structural components are welded, stress-relief heat treatment is carried out. Due to constraints related to the annealing furnace, it can only be used at night; during that time, the temperature can only be raised to 500°C. During the day, the power is turned off to stop the heating process, and heating resumes the next night to reach 600°C, after which the temperature is maintained at that level. Can such annealing treatment have an impact on structural components?
This stepwise annealing process has a minimal impact on the structural components. Although it is not completed in one go, the nightly heating and holding process is sufficient to relieve the stresses generated by welding and improve the microstructure, thereby achieving the effect of stress-relief heat treatment. It should be noted, however, that during the annealing process, the heating rate and temperature must be carefully controlled, along with ensuring an adequate holding time, in order to guarantee the effectiveness of the treatment and the quality of the product. .
